    CRAMER v TRANSITIONAL HEALTH SERVICES OF WAYNE
    Docket No. 163559. Argued December 8, 2022 (Calendar No. 3). Decided July 28, 2023.
    Agnes N. Cramer petitioned for workers’ compensation benefits for the alleged physical
    and mental injuries she sustained after suffering an electrical shock and falling from a ladder while
    working for Transitional Health Services of Wayne, which was insured by American Zurich
    Insurance Company. Plaintiff asserted that, as a result of the shock and fall, she injured her right
    shoulder and suffered from post-traumatic stress disorder (PTSD) and non-epileptic seizures. The
    magistrate denied benefits for plaintiff’s PTSD/non-epileptic seizure claim, finding that there was
    insufficient evidence that the disability was work-related. Applying the four-factor test set forth
    in Martin v Pontiac Sch Dist, 2001 ACO 118, the magistrate concluded that plaintiff failed to meet
    her burden of proof that her employment contributed to or accelerated her mental injuries in a
    significant manner as required by MCL 418.301(2) of the Worker’s Disability Compensation Act
    (MWDCA), MCL 418.101 et seq. The magistrate also denied wage-loss benefits on the basis that,
    although plaintiff was physically disabled from the injury to her shoulder, there was no evidence
    that plaintiff had made a good-faith effort to secure other employment. Plaintiff appealed the
    magistrate’s ruling to the Michigan Compensation Appellate Commission, questioning whether
    Martin was consistent with MCL 418.301(2). The commission affirmed the magistrate’s denial
    of benefits for mental/emotional problems, concluding that (1) the magistrate correctly determined
    that the workplace incident did not significantly contribute to plaintiff’s emotional difficulties; (2)
    the magistrate’s determination that plaintiff’s emotional problems were not work-related was
    supported by competent, material, and substantial evidence; (3) the magistrate applied the correct
    analysis to find that plaintiff had no organic neurologic problems and that the magistrate’s finding
    in that regard was supported by competent, material, and substantial evidence; and (4) Martin was
    binding in cases applying MCL 418.301(2). However, the commission reversed the magistrate’s
    denial of wage-loss benefits for plaintiff’s shoulder injury. Plaintiff and defendants separately
    sought leave to appeal in the Court of Appeals. In Court of Appeals Docket No. 347745, the Court
    of Appeals denied defendants’ application for lack of merit in the grounds presented. In Docket
    No. 347806, the Court of Appeals remanded the matter to the Board of Magistrates for a
    determination of whether plaintiff was entitled to a discretionary award of attorney fees on unpaid
    medical benefits; the Court denied the remainder of the application for lack of merit in the grounds
    presented. Plaintiff sought leave to appeal that order in the Supreme Court. In lieu of granting the
    application, the Supreme Court remanded the case to the Court of Appeals for consideration as on
    leave granted. 
    505 Mich 1022
     (2022). In a split opinion, the Court of Appeals, JANSEN and
    BECKERING, JJ. (SHAPIRO, P.J., dissenting), affirmed the commission. In addressing the questions
    as posed in the Supreme Court order, the Court of Appeals held that (1) the commission correctly
    concluded that the magistrate had properly applied both the four-factor Martin test and the standard
    set forth in Yost v Detroit Bd of Ed, 2001 Mich ACO 118; (2) Martin was not at odds with the rule
    that the presence of a preexisting condition is not a bar to eligibility for MWDCA benefits and
    does not conflict with MCL 418.301(2); and (3) the commission correctly concluded the record
    contained competent, substantial, and material evidence to support the magistrate’s finding of a
    lack of causation. 
    338 Mich App 603
     (2021). Plaintiff sought leave to appeal in the Supreme
    Court, and the Supreme Court granted the application, limited to two issues: (1) whether the four-
    factor test in Martin is at odds with the principle that a preexisting condition is not a bar to
    eligibility for workers’ compensation benefits and conflicts with the plain meaning of MCL
    418.301(2), and (2) assuming that Martin provides the appropriate test, whether the Court of
    Appeals erred by affirming the commission’s conclusion that the magistrate properly applied
    Martin as well as the standard in Yost. 
    509 Mich 871
     (2022).
    In an opinion by Chief Justice CLEMENT, joined by Justices BERNSTEIN, CAVANAGH, and
    WELCH, the Supreme Court held:
    MCL 418.301(2) provides that mental disabilities and conditions of the aging process,
    including but not limited to heart and cardiovascular conditions and degenerative arthritis, are
    compensable if contributed to or aggravated or accelerated by the employment in a significant
    manner. Martin was overruled to the extent it established an exclusive test, in place of a totality-
    of-the-circumstances analysis, because that test was contrary to MCL 418.301(2) and imposed a
    higher burden on claimants than the statute requires. The Court adopted a clarified version of the
    test set forth in Farrington v Total Petroleum, Inc, 
    442 Mich 201
     (1993), as the test to apply when
    claimants seek compensation under MCL 418.301(2). A claimant must show that their health
    injury was significantly caused or aggravated by employment considering the totality of all the
    occupational factors and all the claimant’s health circumstances and nonoccupational factors.
    Occupational factors include: the temporal proximity of the health problem to the work experience,
    the physical stress to which the claimant was subjected, the conditions of employment, and the
    repeated return to work after each instance of a health problem; the occupational factors must be
    considered together with the totality of a claimant’s health circumstances to analyze whether the
    health problem was significantly caused by work-related events. In evaluating mental injuries, all
    nonoccupational factors must be measured against all occupational factors to determine if the
    significant manner requirement is satisfied. Because the magistrate applied Martin in their
    decision, the magistrate’s findings were vacated. The Court of Appeals judgment was reversed,
    and the case was remanded for further proceedings.
    1. With regard to workers’ compensation benefits, MCL 418.301(2) provides that mental
    disabilities and conditions of the aging process, including but not limited to heart and
    cardiovascular conditions and degenerative arthritis, are compensable if contributed to or
    aggravated or accelerated by the employment in a significant manner. Mental disabilities are
    compensable if arising out of actual events of employment, not unfounded perceptions thereof,
    and if the employee’s perception of the actual events is reasonably grounded in fact or reality.
    Thus, to recover compensation under MCL 418.301(2) for mental injuries, a claimant must
    establish: (1) a mental disability, (2) that arises out of actual events of employment, and (3) that
    those events contributed to or aggravated the mental disability in a significant manner.
    2. In determining whether a disability arising out of a workplace injury is eligible for
    compensation under MCL 418.301(2), the Martin test required the fact-finder to consider: (1) the
    number of occupational and nonoccupational contributors to the disability, (2) the relative amount
    of contribution of each contributor, (3) the duration of each contributor, and (4) the extent of
    permanent effect that resulted from each contributor. While Martin was originally designed to
    interpret the term “significant,” it instead became the test for overall compensability. Martin
    created confusion and led to inconsistent resolution of workers’ compensation claims because,
    while it stated that the four-factor test was not a bright-line test or checklist, it then stated that it
    had adopted a definition for significant contribution that could be satisfied only when the four-
    factor test was met, resulting in some panels adhering strictly to the four factors, while other panels
    considered additional factors. To the extent that Martin established an exclusive test, in place of
    a totality-of-the-circumstances analysis, that test was contrary to MCL 418.301(2) and imposed a
    higher burden on claimants than the statute requires. Specifically, the Martin test exhibited bias
    against finding for claimants and was problematic because courts, magistrates, and the commission
    functionally used Martin as a bright-line test, ignoring the rest of the statute and factors not
    enumerated by Martin. Moreover, Martin erroneously construed “a significant manner” to mean
    the most significant manner, in contradiction of the statutory text. In addition, the limited factors
    in Martin often tipped the scales in favor of noncompensability: although Martin stated that
    overwhelming proofs regarding one factor could overcome the absence of proof regarding another
    factor, the Martin test was not applied like that; in particular, the commission applied the test as
    requiring noncompensation merely because one of the four factors was absent or as allowing the
    disregard or minimization of evidence that did not fit under one of the four factors. The Martin
    test was overruled because it conflicted with the plain meaning of MCL 418.301(2) and was at
    odds with the principle that a preexisting condition is not a bar to eligibility for workers’
    compensation benefits.
    3. In place of Martin, the test set forth in Farrington should be used. That case held that,
    under MCL 418.301(2), a claimant must show that their health injury was significantly caused or
    aggravated by employment considering the totality of all the occupational factors and the
    claimant’s health circumstances and nonoccupational factors. Occupational factors include: the
    temporal proximity of the health problem to the work experience, the physical stress to which the
    claimant was subjected, the conditions of employment, and the repeated return to work after each
    instance of a health problem; this list is not all-inclusive. Stated differently, the occupational
    factors must be considered together with the totality of a claimant’s health circumstances to
    analyze whether the health problem was significantly caused by work-related events. The
    Farrington test was clarified, in part, by Lombardi v William Beaumont Hosp (On Remand), 
    199 Mich App 428
     (1993), which held that the “significant manner” test requires analysis of whether
    the events occurring at work had more than a minor contributing, aggravating, or accelerating
    effect in the overall psychiatric scheme, which involves reviewing and comparing all the factors
    contributing to the disability, both occupational and nonoccupational; in evaluating mental
    injuries, all nonoccupational factors must be measured against all occupational factors to determine
    if the significant manner requirement is satisfied. Thus, reviewing workers’ compensation claims
    under MCL 418.301(2) requires consideration of the totality of the circumstances, including, but
    not limited to, those factors discussed in Farrington and Lombardi. Under this clarified
    Farrington test, the four Martin factors may still be relevant in considering the totality of the
    circumstances—but only as part of the inquiry, not the whole inquiry.
    4. Because the magistrate and the commission in this case applied the Martin four-factor
    test, the findings of the magistrate were vacated, the judgment of the Court of Appeals was
    reversed, and the case was remanded for further proceedings, including a redetermination applying
    the new clarified Farrington standard and MCL 418.301(2).
    Magistrate’s findings vacated, Court of Appeals judgment reversed, and case remanded for
    further proceedings.
    Justice ZAHRA, joined by Justice VIVIANO, dissenting, disagreed with the majority’s
    conclusion that Martin’s four-factor test conflicted with MCL 418.301(2) and was at odds with
    the principle that a preexisting condition is not a bar to the receipt of workers’ compensation
    benefits. Because there was a lack of evidence supporting plaintiff’s claim of developing non-
    epileptic seizures as a result of her accident, the case was a poor vehicle to consider altering the
    longstanding standards set forth in Martin. Further, MCL 418.861a(14) requires the judiciary to
    treat the commission’s factual findings as conclusive in a workers’ compensation case if there is
    any evidence supporting that decision. By premising its conclusions on facts that were not
    accepted by the commission, the majority’s recitation of facts violated MCL 418.861a(14). In
    addition, none of the majority’s criticisms of Martin was compelling. The Martin test was
    consistent with caselaw interpreting MCL 418.301(2). Indeed, the Martin test set forth sound
    guidance for determining whether occupational factors contributed in a significant manner to a
    claimant’s existing mental disability. The majority’s addition of the Farrington factors did not
    resolve any perceived conflict between Martin and the text of MCL 418.301(2); it also did not
    bolster the principle that a preexisting condition is not a bar to the receipt of benefits any more
    than Martin. In fact, the Farrington factors are subsumed by the Martin factors as applied and,
    when relevant, integrated into a proper application of the Martin test. At most, the majority should
    have clarified and emphasized that the four-factor test in Martin was not dispositive and allowed
    for any relevant factors to be considered, including the Farrington factors if applicable. The
    majority failed to offer a sound basis for overruling Martin, and in its place established a test
    requiring consideration of additional factors that are not very relevant to mental disability claims
    under MCL 418.301(2). Justice ZAHRA would have affirmed the Court of Appeals judgment
    affirming the commission’s decision, which in turn, affirmed the magistrate’s denial of benefits
    for plaintiff’s alleged mental disability. Because it was unlikely that plaintiff would be able to
    establish her claim under the majority’s new test, Justice ZAHRA would not have remanded the
    case for further proceedings and instead would have affirmed the denial of plaintiff’s mental
    disability claim.
    Justice BOLDEN did not participate in the disposition of this case because the Court
    considered it before she assumed office.

    Plaintiff-Appellant,
    v                                                                No. 163559

    INSURANCE COMPANY,
    Defendants-Appellees.
    BEFORE THE ENTIRE BENCH (except BOLDEN, J.)
    CLEMENT, C.J.
    This case presents two questions arising under Michigan’s Worker’s Disability
    Compensation Act (MWDCA), MCL 418.101 et seq. First is whether the four-factor test
    laid out in Martin v Pontiac Sch Dist, 2001 ACO 118, lv den 
    466 Mich 873
     (2002), conflicts
    with MCL 418.301(2). Second is whether Martin is at odds with the principle that a
    preexisting condition is not a bar to the receipt of workers’ compensation benefits. We
    answer both questions in the affirmative.
    The test set forth in Martin—initially designed to be used merely as a “guide” when
    determining whether a plaintiff has demonstrated that their workplace injury significantly
    contributed to the claimed disability—has morphed into a straitjacket. 1 For more than 20
    years, Martin has effectively replaced MCL 418.301(2), requiring plaintiffs to meet a
    higher burden than what the Legislature intended and enacted. Martin’s strict, four-factor
    test is routinely misapplied in workers’ compensation cases, potentially depriving plaintiffs
    of benefits to which they may be entitled under the proper test. Today, this Court seeks to
    remedy this issue and ensure proper application of MCL 418.301(2) by overruling Martin
    and adopting a clarified version of the test set forth in Farrington v Total Petroleum, Inc,
    
    442 Mich 201
    ; 
    501 NW2d 76
     (1993). Accordingly, we reverse the Court of Appeals’
    judgment applying the now-overruled Martin test and remand this case to the magistrate
    for consideration under the clarified Farrington standard.
    I. FACTUAL AND PROCEDURAL BACKGROUND
    Plaintiff, Agnes Cramer, worked as the dietary manager for defendant Transitional
    Health Services of Wayne, a nursing care facility. In February 2012, while wiping off a
    light fixture with a damp rag at work at the instruction of her manager, plaintiff was
    1
    Justice ZAHRA’s dissent belabors the assertion that because Martin was intended to be a
    mere “guide” and because “its four-factor test is not dispositive,” “there is not much, if
    any, purpose served by the action taken by the Court in this case.” However, the majority’s
    interest in taking on this case is premised on this exact point. While it’s true that Martin
    was only supposed to be a guide, over the last two decades, its test has been treated as
    dispositive.
    2
    electrocuted and fell off a ladder. Plaintiff claimed that she hit her shoulder and head, lost
    consciousness, and was rushed to the hospital. Plaintiff testified that she felt disoriented
    in the hospital and could not walk. She complained of pain in her arm, shoulder, and head.
    However, finding no injury to plaintiff at that time, the hospital released plaintiff and
    cleared her to return to work. 2
    Plaintiff returned to work two days later but continued feeling dizzy and disoriented
    and left. She sought a second opinion from her family doctor, who diagnosed her with a
    concussion and sent her to another facility to address her complaints of shoulder pain.
    Plaintiff notified defendant of the concussion diagnosis, and defendant requested that
    plaintiff be evaluated at an outpatient, neurological medical facility. The neuro facility
    confirmed the concussion diagnosis, treated plaintiff for seizures, and reported that plaintiff
    could not return to work.          Plaintiff then received an electroencephalogram (EEG)
    neurological examination at another clinic, but that examination yielded normal test
    results—even though plaintiff and her caregiver still reported six seizure events.
    Plaintiff claimed that she began experiencing seizures in April 2012, about two
    months after her workplace fall. During this time, she began receiving treatment for
    seizures at the hospital, including a two-week continuous video-EEG monitoring test,
    which did not show any evidence of epilepsy. Critical to these proceedings, Dr. Mariana
    Spanaki-Varalas, a board-certified clinical neurophysiologist, determined that these were
    “nonepileptic” seizures, meaning they were not caused by any physical brain abnormality,
    2
    Plaintiff’s workplace accident and subsequent hospital visit occurred on Wednesday,
    February 8, 2012. The hospital released plaintiff that same day, and it cleared her to return
    to work two days later, on Friday, February 10, 2012.
    3
    but by stress. 3 Dr. Spanaki-Varalas also diagnosed plaintiff with post-traumatic stress
    disorder (PTSD), and plaintiff also claimed to be experiencing severe headaches. Dr.
    Spanaki-Varalas related plaintiff’s diagnoses to the workplace accident in February 2012,
    and she transferred plaintiff to psychologist Andrea Thomas for treatment of her non-
    epileptic seizures. Ms. Thomas stated that her Axis I diagnosis for plaintiff was conversion
    disorder characterized by non-epileptic seizures, and she also diagnosed plaintiff with
    PTSD and a major depressive disorder.         Ms. Thomas’s opinion was that plaintiff’s
    conversion disorder and PTSD were either caused or significantly aggravated by plaintiff’s
    workplace accident in February 2012, but she was unable to provide a professional opinion
    as to whether plaintiff’s depression was also related to the accident.
    Plaintiff alleged that she remained unable to work following the accident due to her
    injuries. Plaintiff also alleged that she has only driven her car once since the date of the
    accident because of medical restrictions from her doctors.
    3
    When conversion disorder manifests in seizures, the seizures are referred to as non-
    epileptic seizures. “Conversion disorder is a disorder in which a person experiences
    blindness, paralysis, or other symptoms affecting the nervous system that cannot be
    explained solely by a physical illness or injury. Symptoms usually begin suddenly after
    a period of emotional or physical distress or psychological conflict.” Genetic and
    Rare         Diseases        Information         Center,        Conversion         Disorder
     (accessed June 23,
    2023) [https://perma.cc/3SZ8-6H4L] (emphasis added). The term “nonepileptic” seizures
    is outdated in the medical community, and the “[c]ommonly used current terms for this
    phenomenon are psychogenic nonepileptic spells or seizures (PNES), psychogenic
    nonepileptic episodes (PNEE), or psychogenic nonepileptic attacks. These terms
    reinforce the idea that the events are not epileptic seizures and are of psychiatric origin.”

    Plaintiff petitioned for workers’ compensation benefits for the physical and mental
    injuries she sustained from her workplace fall. Plaintiff’s claims were tried before a
    magistrate judge. Plaintiff and numerous experts testified before the magistrate. At that
    time, defendants elicited testimony from plaintiff regarding other stressors in her life that
    may have contributed to her seizures.        Specifically, plaintiff testified that she was
    repeatedly physically and emotionally abused by her first husband of nineteen years. Upon
    divorcing her abusive husband in 2006, plaintiff was then disowned by her mother, church
    community, and friends—all of whom were unsupportive of the divorce for religious
    reasons. She also lost custody of her children. But despite these challenges, there is no
    evidence in the record that plaintiff had experienced seizures or took any time off work
    between her divorce and the workplace fall as a result of these past experiences. At the
    time of the accident, plaintiff had been divorced from her husband for six years and was
    happily remarried.
    Experts testified regarding plaintiff’s mental injuries. Dr. Gregory Barkley, a board-
    certified neurologist specializing in seizure disorders, diagnosed plaintiff with PTSD and
    explained that the injury physically and mentally devastated her. Dr. Spanaki-Varalas and
    Ms. Thomas testified as to their diagnoses of PTSD and non-epileptic seizures, and both
    testified that plaintiff’s workplace injury significantly contributed to the development of
    her physical and mental injuries. Thomas additionally testified as to her diagnosis of a
    conversion disorder characterized by nonepileptic seizures. After treating plaintiff for
    more than 11 months, Thomas testified before the magistrate. The magistrate summarized
    Thomas’s testimony as follows:
    5
    [The] sole causation opinion of plaintiff’s current diagnosis is a work
    incident of February 8, 2012. If there were any other prior issues they were
    not evident and they were not causing her problems. The seizures began after
    the work incident of February 8, 2012.
    Conversely, one of defendant’s experts, Dr. Manfred F. Greiffenstein, a
    neuropsychologist, testified that plaintiff was not disabled from a psychological standpoint
    and that any mental health treatment she needed was not connected to the work accident.
    He diagnosed her with pseudo-seizures 4 and noted no cognitive difficulties.             Dr.
    Greiffenstein opined, without reference to any of plaintiff’s medical records prior to the
    workplace incident, that she suffers from “weaknesses in [her] personality” that had likely
    been around since adolescence. He dismissed a connection to the workplace incident
    because, in his words, if it had happened to him, he would not have been traumatized. He
    testified that only a life-threatening event or threat of serious physical injury would be
    stressful enough to be causally related to employment and that plaintiff’s fall from a ladder
    wasn’t enough to cause such a severe physical and mental response. Dr. Wilbur Boike, a
    neurologist who focuses on spinal injuries, agreed with the pseudo-seizure diagnosis but
    expressed skepticism at plaintiff’s “convenient” self-reporting of symptoms.
    The magistrate issued an opinion that (1) denied benefits for plaintiff’s
    PTSD/nonepileptic-seizure claim, finding that there was insufficient evidence that the
    4
    “Pseudoseizure is an older term for events that appear to be epileptic seizures but, in
    fact, do not represent the manifestation of abnormal excessive synchronous cortical
    activity, which defines epileptic seizures. They are not a variation of epilepsy but are of
    psychiatric origin. Other terms used in the past include hysterical seizures, psychogenic
    seizures, and others. The most standard current terminology is psychogenic nonepileptic
    seizures (PNES).”           Huff & Murr, Psychogenic Nonepileptic Seizures
     (accessed June 23, 2023)
    [https://perma.cc/WK8T-L7MT].

    disability was work-related, and (2) denied lost wages because, although plaintiff was
    physically disabled from the injury to her right shoulder, there was no evidence that
    plaintiff had made a good-faith effort to secure other employment, and thus, lost wages
    were denied. 5
    Relevant to the appeal before us today, the magistrate concluded plaintiff failed to
    meet her burden of proof that her employment “contributed to or aggravated or accelerated”
    her mental injuries “in a significant manner” as required by MCL 418.301(2).            In
    determining whether the occupational contributors met the definition of “significant” in
    MCL 418.301(2), the magistrate applied the four-factor test set forth in Martin, 2001 ACO
    118, considering: (1) the number of occupational and nonoccupational contributors, (2) the
    relative amount of contribution of each contributor, (3) the duration of each contributor,
    and (4) the extent of permanent effect that resulted from each contributor.
    Applying Martin to plaintiff’s claims, the magistrate first compared the sole
    occupational contributor of the electric shock and fall from the ladder to the
    nonoccupational factors of cumulative physical and mental abuse from plaintiff’s prior
    marriage and the separation from her family, community, and children after the divorce.
    The magistrate concluded that these nonoccupational contributors outnumbered the
    occupational contributors. As for the relative duration of the contributors, the magistrate
    5
    The claim related to plaintiff’s shoulder injury is not subject to this appeal as the
    magistrate’s decision on that issue was reversed by the Commission and the parties did not
    further raise the issue. The Commission specifically reversed the portion of the
    magistrate’s order that denied plaintiff wage-loss benefits for the shoulder injury and
    affirmed the remainder of the order, including the magistrate’s finding that plaintiff was
    not entitled to workers’ compensation benefits for emotional problems or organic
    neurologic problems.
    7
    determined that the nonoccupational stressors were continuing, whereas the work event
    was a one-time incident. Finally, the magistrate noted that there was no objective evidence
    of permanent effects to plaintiff from the workplace incident. She rejected the expert
    testimony presented by plaintiff’s witnesses regarding causation, in part, because those
    experts failed to establish a hierarchy of plaintiff’s nonoccupational stressors compared
    with her occupational stressors. The magistrate instead relied on defendant’s experts, who
    testified there was no objective neurological abnormality accounting for plaintiff’s
    subjective symptoms and no objective evidence of any involvement of the central nervous
    system due to head trauma. The magistrate also relied on the experts’ testimony providing
    that health services were indicated for interpersonal conflicts, but that plaintiff’s personal
    problems predate the incident. Having concluded that plaintiff failed to establish that the
    workplace fall contributed to her mental injuries “in a significant manner,” the magistrate
    rejected plaintiff’s PTSD/nonepileptic-seizure claim for disability benefits.
    Plaintiff appealed the magistrate’s ruling to the Michigan Compensation Appellate
    Commission (the Commission), 6 raising one issue: whether Martin is consistent with
    § 301(2) of the MWDCA, MCL 418.301(2). The Commission affirmed the magistrate’s
    denial of benefits for mental/emotional problems, concluding: (1) that the magistrate
    6
    Governor Gretchen Whitmer’s Executive Reorganization Order No. 2019-13 created the
    Workers’ Disability Compensation Appeals Commission to manage, process, and decide
    appeals from orders of the Director of the Workers’ Disability Compensation Agency and
    the Workers’ Compensation Board of Magistrates. This commission used to be called the
    Michigan Compensation Appellate Commission (the MCAC). At the time that the
    Commission rendered its decision in this case it was still called the MCAC. As the name
    of this body has changed over the years, this opinion simply refers to this body as “the
    Commission” throughout.
    8
    applied the proper analysis in finding that the workplace incident did not significantly
    contribute to plaintiff’s emotional difficulties; (2) that the magistrate’s determination that
    plaintiff’s emotional problems were not work-related was supported by competent,
    material, and substantial evidence; (3) that the magistrate applied the correct analysis to
    find that plaintiff has no organic neurologic problems and that the magistrate’s finding in
    that regard is supported by competent, material, and substantial evidence; and perhaps,
    most importantly (4) that Martin is binding in cases applying MCL 418.301(2). The
    Commission held that the magistrate properly applied Martin’s four-factor test in the
    analysis. Relevant to this appeal, the magistrate rejected the medical opinions of Dr.
    Barkley, Dr. Spanaki-Varalas, and Ms. Thomas, and instead relied on the testimony of Dr.
    Boike and Dr. Greiffenstein.       The Commission concluded that this aspect of the
    magistrate’s decision was supported by “competent, material, and substantial evidence and
    therefore must be affirmed.”
    All parties sought leave to appeal in the Court of Appeals. 7 The Court of Appeals
    denied leave for lack of merit on the issue of compensability for the mental injury. 8

    and Cramer v Transitional Health Servs of Wayne (Court of Appeals Docket No. 347806).
    8
    The Court of Appeals order remanded the matter to the Board of Magistrates for a
    determination of whether plaintiff was entitled to a discretionary award of attorney fees on
    unpaid medical benefits; the Court denied the remainder of the application for lack of merit
    in the grounds presented. See Cramer v Transitional Health Servs of Wayne, unpublished
    order of the Court of Appeals, entered August 16, 2019 (Docket No. 347806). In Docket
    No. 347745, the Court of Appeals denied the application for leave to appeal for lack of
    merit in the grounds presented. Cramer v Transitional Health Servs of Wayne, unpublished
    order of the Court of Appeals, entered August 16, 2019 (Docket No. 347745). The appeal
    in this matter involves only the issues raised and addressed by the parties in Court of
    Appeals Docket No. 347806.
    9
    Plaintiff sought leave to appeal in this Court. In lieu of granting leave to appeal, the
    Court remanded the case to the Court of Appeals for consideration as on leave granted.
    Cramer v Transitional Health Servs of Wayne, 
    505 Mich 1022
     (2020). The remand order
    instructed the Court of Appeals to consider whether
    (1) the Michigan Compensation Appellate Commission correctly concluded
    that the magistrate properly applied the four-factor test in Martin v Pontiac
    Sch Dist, 2001 Mich ACO 118, lv den 
    466 Mich 873
     (2002), and the standard
    in Yost v Detroit Board of Education, 2000 Mich ACO 347, lv den 
    465 Mich 907
     (2001); (2) the Martin test is at odds with the principle that a preexisting
    condition is not a bar to eligibility for workers’ compensation benefits and
    conflicts with the plain meaning of MCL 418.301(2); and (3) the Michigan
    Compensation Appellate Commission correctly concluded that the
    magistrate’s lack of causation conclusion was supported by the requisite
    competent, substantial, and material evidence utilizing the proper standard of
    law. [Cramer, 505 Mich at 1022.]
    On remand, the Court of Appeals issued a split decision affirming the Commission.
    Writing for the majority, Judge JANSEN, joined by Judge BECKERING, held (1) the
    Commission correctly concluded that the magistrate had properly applied the Martin and
    Yost tests, (2) Martin is not at odds with the rule that the presence of a preexisting condition
    is not a bar to eligibility for MWDCA benefits and does not conflict with MCL 418.301(2),
    and (3) the Commission correctly concluded the record contained competent, substantial,
    and material evidence to support the magistrate’s finding of a lack of causation. Cramer v
    Transitional Health Servs of Wayne, 
    338 Mich App 603
    , 628-630, 632-639; 
    980 NW2d 744
     (2021). The majority endorsed the Martin test on the basis that it “essentially conforms
    with the Supreme Court’s own guidance regarding how to apply” MCL 418.301(2) because
    it “provides for a comparison of nonemployment and employment factors.” Id. at 638-639.
    According to the majority, so long as the Martin analysis shows that the “work stressor
    10
    contributed to, aggravated, or accelerated the illness in a significant manner,” a preexisting
    condition will not bar a plaintiff from obtaining benefits. Id. at 639.
    Judge SHAPIRO dissented. He concluded that the Martin test is divorced from the
    statutory text and is “wholly a creation of the commission,” adopted without following
    proper rulemaking procedures. Id. at 647 (SHAPIRO, P.J., dissenting). Judge SHAPIRO
    noted that the Commission incorrectly understood the word “significant,” as used in MCL
    418.301(2), to mean “substantial,” increasing the threshold for relief beyond what the
    Legislature intended. Id. at 647-648. Judge SHAPIRO explained that the Martin test is
    biased against compensating workers, though he acknowledged that the test’s factors are
    not totally irrelevant to evaluating compensability under the statute, just incomplete. Id. at
    650-651. Particularly, when there is a preexisting condition, a single workplace incident
    will never constitute more than one “contributor” and will therefore “never outnumber
    nonoccupational contributors . . . .” Id. at 650. Similarly, a single-event injury “can never
    compare in ‘duration’ to a preexisting condition.” Id.
    Plaintiff sought leave to appeal in this Court, and we granted the application on two
    limited issues: “(1) whether the four-factor test in Martin (a) is at odds with the principle
    that a preexisting condition is not a bar to eligibility for workers’ compensation benefits,
    and (b) conflicts with the plain meaning of MCL 418.301(2); and (2) assuming that Martin
    provides the appropriate test, whether, on this record, the Court of Appeals erred in
    affirming the [Commission’s] conclusion that the magistrate properly applied Martin, as
    well as the standard in Yost v Detroit Bd of Ed, 2000 Mich ACO 347, lv den 
    465 Mich 907
    (2001).” Cramer v Transitional Health Servs of Wayne,

    II. STANDARD OF REVIEW 9
    Under MCL 418.861a(3), the Commission looks at the whole record to determine
    whether the magistrate’s factual findings are supported by competent, material, and
    substantial evidence; if such support exists, the magistrate’s findings of fact are considered
    conclusive. Substantial evidence is defined as “such evidence, considering the whole
    record, as a reasonable mind will accept as adequate to justify the conclusion.” 
    Id.
     When
    interpreting the MWDCA, this Court has explained that “the statute has been liberally
    construed to provide broad coverage for injured workers.” Wells v Firestone Tire &
    Rubber Co, 
    421 Mich 641
    , 651; 
    364 NW2d 670
     (1984).                  Judicial review of the
    Commission’s decision is governed by MCL 418.861a(14), which provides as follows:
    The findings of fact made by the commission acting within its powers,
    in the absence of fraud, shall be conclusive. The court of appeals and the
    supreme court shall have the power to review questions of law involved with
    any final order of the commission, if application is made by the aggrieved
    party within 30 days after the order by any method permissible under the
    Michigan court rules.
    Questions of law involved in workers’ compensation cases are reviewed de novo.

    The plain text of MCL 418.861a(14) expressly grants this Court the power to “review
    questions of law involved with any final order of the commission[.]” As the majority is
    opining strictly on questions of law and, contrary to the dissent’s claim, is not weighing in
    on facts absent from the record, it is acting well within its authority.

    III. HISTORY OF THE MWDCA
    When the Legislature first enacted the MWDCA, the statutory scheme referred only
    to “personal injury” and did not explicitly refer to mental injuries. 10 However, this Court
    later concluded that mental injuries were compensable as a type of personal injury. See,
    e.g., Klein v Len H Darling Co, 
    217 Mich 485
    , 487-489, 494; 
    187 NW 400
     (1922) (holding
    that the decedent’s death from severe emotional shock—the result of injuring a coworker
    and initially believing that he had killed the coworker—was compensable as accidental
    personal injury). In the years that followed, the Court grappled with determining which
    categories of mental disabilities would be compensable. Specifically, determining which
    conditions were “caused” by a workplace injury proved difficult.          This Court later
    concluded that aggravation of a preexisting mental injury could be compensable under the
    statute. Carter v Gen Motors Corp, 
    361 Mich 577
    , 580-583, 591-594; 
    106 NW2d 105
    (1960). In Carter, the Court held that compensation could be awarded for a mental injury
    that arose out of and in the course of employment because of the effects of workplace
    stresses on a preexisting mental injury. 
    Id.
     In Deziel v Difco Laboratories, Inc (After
    Remand), 
    403 Mich 1
    ; 
    268 NW2d 1
     (1978), this Court further examined the causal link
    that must exist between the work and the disability to receive compensation. Deziel
    established a subjective causal analysis based on the claimant’s perceptions, which led to
    10
    1915 CL 5431 provided, in part, “If an employee . . . receives a personal injury arising
    out of and in the course of his employment by an employer . . . , he shall be paid
    compensation in the manner and to the extent hereinafter provided.”
    13
    two problems. First, compensation could be awarded based on a claimant’s imagined or
    perceived version of the events. Second, under Deziel, there was no need to prove causal
    connection between the injury and the employment events.
    In 1980, ostensibly in response to Deziel, the Legislature amended MCL 418.301(2)
    to its current form. MCL 418.301(2) states, in relevant part:
    Mental disabilities and conditions of the aging process, including but
    not limited to heart and cardiovascular conditions and degenerative arthritis,
    are compensable if contributed to or aggravated or accelerated by the
    employment in a significant manner. Mental disabilities are compensable if
    arising out of actual events of employment, not unfounded perceptions
    thereof, and if the employee’s perception of the actual events is reasonably
    grounded in fact or reality. [Emphasis added.]
    Thus, a plaintiff claiming compensation for mental injuries under MCL 418.301(2)
    must “prove: (1) a mental disability; (2) which arises out of actual events of employment,
    not unfounded perceptions thereof; and (3) that those events contributed to or aggravated
    the mental disability in a significant manner.” Zgnilec v Gen Motors Corp (On Remand),
    
    224 Mich App 392
    , 396; 
    568 NW2d 690
     (1997). At issue in this case is whether plaintiff’s
    workplace incident “contributed to or aggravated or accelerated [her mental
    disability] . . . in a significant manner.” MCL 418.301(2) (emphasis added).
    This Court has considered the boundaries of MCL 418.301(2) twice before. This
    Court’s first significant attempt to define this statutory language occurred in Farrington v
    Total Petroleum, Inc, 
    442 Mich 201
    ; 
    501 NW2d 76
     (1993). There, the plaintiff, a 49-year-
    old employee, received workers’ compensation benefits after suffering several on-the-job
    heart attacks. 
    Id. at 204-206
    . The Court affirmed the award of benefits, explaining that
    MCL 418.301(2) required the plaintiff to show that his heart injury was “significantly
    14
    caused or aggravated by employment considering the totality of all the occupational factors
    and the claimant’s health circumstances and nonoccupational factors.” 
    Id. at 216-217
    .
    This Court outlined occupational factors that must be weighed when evaluating the
    “significant manner” requirement under MCL 418.301(2). Those factors included: “the
    temporal proximity of the . . . [health problem] to the work experience, the physical stress
    to which the plaintiff was subjected, the conditions of employment, and the repeated return
    to work after each [instance of a health problem].” 
    Id. at 221
    . However, the Court noted
    that these factors were “not all inclusive,” specifically directing that, “[a]fter the enactment
    of the ‘significant manner’ amendments, these occupational factors must now be
    considered together with the totality of claimant’s health circumstances to analyze whether
    the heart injury was significantly caused by work-related events.” 
    Id. at 221-222
    .
    Later, in Gardner v Van Buren Pub Sch, 
    445 Mich 23
    , 47; 
    517 NW2d 1
     (1994),
    overruled on other grounds by Robertson v DaimlerChrysler Corp, 
    465 Mich 732
    ; 
    641 NW2d 567
     (2002), 11 this Court built upon its ruling in Farrington for a claim premised on
    11
    The Robertson Court questioned the idea that individuals with mental injuries or
    disabilities could, in many cases, “misperceive or altogether lose contact with reality.”
    Robertson, 
    465 Mich at 751
    . The Robertson Court noted that Gardner took a broad view
    of this by reasoning that “it would be ‘absurd’ to allow compensation for a mental disability
    injury resulting from an actual event of employment only to subsequently ‘exclude[] the
    vast majority of all mental disabilities [which are often] based on unfounded perceptions
    of actual events.’ ” 
    Id.
     (first alteration in original), quoting Gardner, 
    445 Mich at 44
    .
    Addressing Gardner further, this Court stated:
    [T]o satisfy the mental disability requirements of the second sentence of
    [MCL 418.301(2)], a claimant must demonstrate: (a) that there has been an
    actual employment event leading to his disability, that is, that the event in
    question occurred in connection with employment and actually took place;
    and (b) that the claimant’s perception of such actual employment event was
    not unfounded, that is, that such perception or apprehension was grounded in
    fact or reality, not in the delusion or the imagination of an impaired mind.
    15
    a mental disability. Gardner held that when evaluating mental injuries, all nonoccupational
    factors must be measured against all occupational factors to determine if the significant-
    manner requirement of MCL 418.301(2) is satisfied. Gardner emphasized that employers
    must “take employees as they find them, with all preexisting mental and physical frailties.”
    Gardner, 
    445 Mich at 48
    . The Gardner Court specifically concluded that when evaluating
    whether a disability is compensable, the issue is not whether a reasonably healthy person
    would have been injured under the circumstances. Instead, “[i]t is whether a specific
    individual, regardless of preexisting conditions, sustained an injury that arose out of, and
    in the course of employment.” 
    Id.
     The Court recognized that, “[a]bsent an explicit
    legislative mandate, mental disabilities should not be treated differently [than physical
    injuries].” 
    Id. at 48-49
    .
    Also relevant is a portion of a pre-Gardner opinion from the Court of Appeals—
    Lombardi v William Beaumont Hosp (On Remand), 
    199 Mich App 428
    ; 
    502 NW2d 736
    (1993)—in which an individual sought compensation for a psychiatric disability that he
    argued was the result of “repeated verbal and physical abuse on the job from co-workers
    and supervisors.” Id. at 429. Regarding the “significant manner” criteria in MCL
    418.301(2), the Court of Appeals opined:
    Because significance is a relative concept, the significant manner test
    requires an analysis whether the events occurring at work had more than a
    minor contributing, aggravating, or accelerating effect in the overall
    psychiatric scheme. This necessarily involves a review and comparison of
    all the factors contributing to disability, both occupational and non-
    occupational. [Id. at 435-436 (emphasis added, citations omitted).]
    To the extent that Gardner is inconsistent with this interpretation of [MCL
    418.301(2)], we overrule it. [Robertson, 
    465 Mich at 752-753
    .]
    16
    The Court of Appeals remanded the case to the Workers’ Compensation Appeal Board due,
    in part, to the board’s failure to consider or weigh nonoccupational factors that could have
    contributed to the plaintiff’s disability. Id. at 436.
    In Yost, 2000 Mich ACO 347, the Commission further explored preexisting
    conditions under MCL 418.301(2). The Commission rejected the plaintiff’s argument that,
    despite her preexisting health conditions, her workplace injury was compensable merely
    because it was the “ ‘last straw’ ” that caused her mental and physical injuries. Id. at 6.
    Yost concluded that the plaintiff’s argument was unavailing and conflicted with MCL
    418.301(2). See id. at 2 & n 2. Specifically, the Commission determined that the last factor
    in a given causal chain does not automatically qualify as “significant” under the statute,
    simply because it came last. Id. at 5, 6. Nothing more, nothing less. In short, not every
    “last straw” workplace incident will be automatically compensable:
    Evidence of structural change or a mere shift from asymptomatic status to
    symptomatic status is never enough, standing alone, to demonstrate
    significant contribution, because a pre-existing condition might be so severe
    that a minor, insignificant workplace event pushes the employee over the
    edge into a symptomatic condition, providing merely the ‘last straw breaking
    the camel’s back.’ The full extent of the underlying pre-existing condition
    must be understood when determining whether the workplace injury
    significantly contributed to a disabling condition. [Id. at 6.]
    If that were not the case, said the Commission, the “significant factor” language
    would be stripped of all meaning, and MCL 418.301(2) would become more or less
    “identical to the regular ‘any contribution’ standard otherwise applicable [under MCL
    418.300 et seq. of the MWDCA].” Id. at 2 n 2. Yost requires more than a quick glance at
    the order of events; it requires the fact-finder to consider the totality of the circumstances—
    including, specifically, temporal proximity and severity of the injury.
    17
    Despite this Court’s holdings in Farrington and Gardner, the Court of Appeals’
    decision in Lombardi, and the Commission’s decision in Yost, magistrate judges and the
    Commission struggled to uniformly apply MCL 418.301(2). In an attempt to provide
    greater consistency, the Commission issued an en banc decision 12 setting forth the “Martin
    test.” In Martin, the Commission addressed how to interpret the “significant manner”
    language from MCL 418.301(2). In determining whether a disability arising out of a
    workplace injury is eligible for compensation, the four-factor Martin test requires the fact-
    finder to consider: “1) the number of occupational and non-occupational contributors [to
    the disability], 2) the relative amount of contribution of each contributor, 3) the duration of
    each contributor, and 4) the extent of permanent effect that resulted from each contributor.”
    Martin, 2001 Mich ACO 118, p 16. While Martin was originally designed to interpret the
    term “significant,” it has become the touchstone for overall compensability.
    However, this four-factor test was not intended to be dispositive. The Martin
    Commission specified:
    [W]e avoid creating a bright-line test or checklist. Instead, we propose
    factors which concentrate the analysis on the fundamental evidence
    regarding increased contribution. We prefer factors because factors differ
    from elements. Each element requires a preponderance of proof. Factors do
    not require such proof. Rather, overwhelming proofs regarding one factor
    can overcome the absence of proof regarding another factor. [Id. at 12.]
    12
    This is especially significant because en banc Commission decisions serve as binding
    precedent on other Commission panels under MCL 418.274(3) (“Any matter that is to be
    reviewed by the commission that may establish a precedent with regard to worker’s
    compensation in this state as determined by the chairperson, or any matter that 2 or more
    members of the commission request be reviewed by the entire commission, shall be
    reviewed and decided by the entire commission.”).
    18
    But the Commission then contradicted itself. After stating that the Martin factors are not
    supposed to be a “bright-line test or checklist,” the Commission declared, “we have
    adopted a definition for significant contribution that can be satisfied only when a four-
    factor test is met,” and then restated the factors. Id. at 15-16 (emphasis added). Martin’s
    conflicting characterization of its test has resulted in widespread confusion and
    inconsistency in resolving workers’ compensation claims, as some Commission panels
    strictly adhere to considering only the four factors, while others consider additional
    factors. 13
    IV. THE MARTIN TEST
    Martin and its inconsistency had remained confined to the Commission and its
    panels until the present case, when the Court of Appeals affirmed that Martin created an
    exclusive test. We disagree and now hold that, insofar as Martin established an exclusive
    test, in place of a totality-of-the-circumstances analysis, that test is contrary to MCL
    418.301(2) and imposes a higher burden on claimants than the statute requires. 14
    13
    In this case, the Commission concluded that the Martin test is binding and exclusive
    when applying MCL 418.301(2). Cramer v Transitional Health Servs of Wayne, 2019
    Mich ACO 4, p 11. However, other panels have considered it a nonbinding guide. See,
    e.g., Dortch v Yellow Transp, Inc, 2007 ACO 21, p 4.
    14
    The Court of Appeals opinion stated, “While we do not conclude that there are grounds
    to overturn Martin, we acknowledge that magistrates and the [Commission] should always
    remain cognizant that there can be more than one contributor or group of contributors
    affecting a mental disability ‘in a significant manner’ and that the Martin test is only a
    guide to aid in the fact-finding process.” Cramer, 338 Mich App at 643. The majority
    finds this reasoning to be internally inconsistent in the same way as Martin. Either the test
    is exclusive, and all the factors must be met, or it’s a nonexclusive guide; it cannot
    simultaneously be both.
    19
    The Martin test requires a comparative analysis of the four identified factors when
    deciding whether an employee’s work has significantly contributed to, aggravated, or
    accelerated a mental disability. Generally, “[w]hen the non-occupational contributors
    outnumber the importance of various occupational contributors,” a worker’s claim for
    disability benefits will likely fail. Martin, 2001 Mich ACO 118, p 12. Under Martin,
    “significant contribution requires more than minimal contribution,” but “ ‘significant’ does
    not require a preponderance standard where work contributors in combination with any
    natural progression of the condition accelerate the condition more than non-work
    contributors.” Id.
    The Martin test, in both theory and practice, exhibits bias against finding for
    plaintiffs and is problematic for three reasons. First, Martin’s test does not reflect the
    statutory language. Although Martin was only supposed to define the term “significant”
    as used in MCL 418.301(2), it is functionally being used by courts, magistrates, and the
    Commission as the start and end of the analysis, with fact-finders ignoring the rest of the
    statute and factors not enumerated by Martin. In particular, the test erroneously construes
    the statutory language “a significant manner” to mean the most significant manner, in total
    contradiction of the statutory text. However, MCL 418.301(2) permits compensation for
    mental injuries if the employment contributes to, or aggravates, or accelerates the injury
    “in a significant manner.” (Emphasis added.)
    This Court has previously emphasized the difference between “a” and “the” for
    purposes of statutory interpretation. For example, in Paige v Sterling Heights, 
    476 Mich 495
    , 507-508; 
    720 NW2d 219
     (2006), this Court stated:
    20
    Traditionally in our law, to say nothing of our classrooms, we have
    recognized the difference between “the” and “a.” “The” is defined as
    “definite article. 1. (used, esp. before a noun, with a specifying or
    particularizing effect, as opposed to the indefinite or generalizing force of
    the indefinite article a or an) . . . .” Random House Webster’s College
    Dictionary, p 1382. Further, we must follow these distinctions between “a”
    and “the” as the Legislature has directed that “all words and phrases shall be
    construed and understood according to the common and approved usage of
    the language . . . .[”] MCL 8.3a[.] [Quotation marks and citation omitted.]
    Under this logic, it must follow that, as used in MCL 418.301(2), the phrase “a significant
    manner” cannot be understood to mean “the most significant manner.”
    Martin’s contorted reading of the statute was highlighted in Taig v Gen Motors
    Corp, 2006 Mich ACO 134, for example. There, the Commission criticized Martin’s
    requirement that the claimant prove that the workplace was “ ‘the most significant’ ” cause
    of the disability. Id. at 13. The Taig panel explained:
    [Martin] creates a legal standard far a field [sic] from the one envisioned by
    MCL 418.301(2). Martin fails to recognize that there can be more than one
    significant contributing factor in a compensable condition. . . .
    * * *
    . . . [I]f the work-related conditions are found not to have aggravated
    the condition “in a significant manner” because some other condition is more
    significant, this is legal error because it alters the legislative scheme of “in a
    significant manner” into requiring the employment conditions be “the most
    significant” cause of the injury before it will be found to be compensable.
    This is precisely the kind of shift in policy that is not the role of the
    administrative agency to make.
    . . . [T]he obligation here is to interpret MCL 418.301(2) according to
    its plain language. Any issues relating to the soundness of the policy
    underlying the statute or its practical ramifications are properly directed to
    the Legislature. To follow Martin is to “rewrite the plain statutory language
    and substitute our own policy decisions for those already made by the
    Legislature.” [Id. at 11-13 (citations omitted).]
    21
    If the Legislature intended the phrase “in a significant manner” to be understood as “the
    most significant manner,” it would have so provided. The Legislature did not do so
    however, and Martin’s requirement to construe the statute as such is erroneous. 15
    Second, as evidenced by the magistrate, the Commission, and the Court of Appeals
    panel here, Martin is being treated as a bright-line test, as opposed to the “guide” it was
    intended to be. See, e.g., Bolden v DaimlerChrysler Corp, 2006 Mich ACO 170, p 7
    (“Martin is not, in our view, a bright line test for compensability in conditions of the aging
    process.”); Dortch v Yellow Transp, Inc, 2007 Mich ACO 21, p 4 (“We repeat our previous
    caution that the factors enumerated in Martin should act as merely guides, aiding the fact
    finder in their often difficult task of weighing the evidence before them, and not as a
    Bright-Line test.”) (emphasis added); Jones-Stott v Henry Ford Hosp, 2007 Mich ACO 31,
    p 6 (“[W]e continue to believe that Martin . . . is not a bright line test but it can be a useful
    tool in some cases involving the aging process.”) (emphasis added).
    Finally, the limited factors themselves often tip the scales in favor of
    noncompensability. Factors one and three are most problematic and inherently biased
    against plaintiffs. Contrary to Martin’s assertion that “overwhelming proofs regarding one
    factor can overcome the absence of proof regarding another factor,” Martin, 2001 ACO
    15
    Compare MCL 712B.3(l) (“[T]he Indian child’s tribe is the tribe with which the Indian
    child has the most significant contacts.”) (emphasis added); MCL 700.7107 (twice using
    “the most significant” relationship when describing the law of the jurisdiction designations
    and the absence of such a designation in trusts); MCL 722.26d(b) (“[T]he action shall be
    filed in the circuit court in the county having the most significant connection with the
    child.”) (emphasis added); and Paige, 
    476 Mich at 499
     (holding that the phrase “the
    proximate cause” in MCL 418.375(2) means “the sole proximate cause”), with Doe v Dep’t
    of Corrections, 
    312 Mich App 97
    , 107-108; 
    878 NW2d 293
     (2015) (holding that the phrase
    “a prisoner” in MCL 600.5507(2) applies to all prisoners rather than only indigent
    prisoners), vacated in part on other grounds 
    499 Mich 886
     (2016).
    22
    118, p 12, application of the test in Martin and subsequent cases has been rigid and
    formulaic. Application of the Martin test has conflicted with the statutory scheme to the
    extent that the Commission has read the test as requiring noncompensation merely because
    one of the four factors is absent or as allowing the disregard or minimization of evidence
    that does not neatly fit under one of the four factors.
    The first factor involves the raw counting of the number of occupational and
    nonoccupational stressors. Here, as in most cases, the number of nonoccupational stressors
    are greater in number than the occupational stressors because workplace injuries resulting
    in workers’ compensation claims usually involve a one-time accident. A person can
    understandably acquire several stressors throughout the course of their life before their
    workplace accident. We agree with the dissent that nonoccupational factors are relevant.
    However, under the current application of Martin, more nonoccupational factors points
    toward noncompensability as a result of raw mathematics. This puts a thumb on the scale
    in favor of noncompensability in a way that MCL 418.301(2) does not require or permit.
    The second factor of the Martin test requires quantifying the relative amount of
    contribution, acceleration, or aggravation of each factor. While we decline to comment on
    how the magistrate and Commission applied this factor in this case, more general
    commentary is warranted. Experts are not required to present their testimony in the form
    of a hierarchical analysis of the contribution, acceleration, or aggravation of each
    occupational and nonoccupational factor. Even under Martin, such weighing and analysis
    is the job of the magistrate and the Commission based on the evidence, not medical experts
    who provide testimony and medical opinions. Nonphysical workplace-injury disputes will
    typically involve competing testimony from medical experts and potentially conflicting
    23
    medical records, which puts the reliability and veracity of experts at issue. Magistrates and
    the Commission must remain cognizant of the area of expertise and experience of testifying
    experts, and whether they have experience dealing with the specific neurological or
    psychological conditions that are allegedly at issue when determining the reliability and
    the veracity of expert testimony. 16
    The third factor looks at the “duration of each contributor,” Martin, 2001 ACO 118,
    p 16, with longer duration indicating higher contribution. Like the first, this factor tends
    to generate findings of noncompensability any time a plaintiff suffers from a longstanding
    preexisting condition. Placing too much weight on the duration of a preexisting condition
    or contributor risks writing “aggravat[ion]” out of MCL 418.301(2). 17
    Martin’s fourth and final factor is “whether any permanent effect resulted from any
    contributor.” Martin, 2001 ACO 118, p 13. Thus, the magistrate must evaluate the ability
    of medical treatment, including rest and abstaining from work, to reverse the effect of the
    16
    Although Mich Admin Code, R 418.97(3) does not require expert testimony to satisfy
    Daubert v Merrell Dow Pharmaceuticals, Inc, 
    509 US 579
    ; 
    113 S Ct 2786
    ; 
    125 L Ed 2d 469
     (1993), in many ways magistrates and the Commission must still fulfill the same
    gatekeeper function as circuit courts do when considering the reliability of proposed expert
    evidence under MRE 702. See Rule 418.97(1) (“Except as provided in these rules, the
    Michigan rules of evidence, as applied in a civil case in circuit court, must be followed in
    all proceedings as far as practicable, but a magistrate may admit and give probative effect
    to evidence of a type commonly relied upon by reasonably prudent persons in the conduct
    of their affairs.”).
    17
    Much of Justice ZAHRA’s dissent revisits the facts, with an unnecessary focus on the
    various family-related hardships plaintiff experienced before her workplace fall. We do
    not dispute the existence of these hardships. However, the dissent fails to recognize that
    the record lacks any evidence that plaintiff ever missed work, was diagnosed with any
    serious or disabling mental illness, or was affected in any other way as a result of these
    prior hardships. Plaintiff’s employment-related complaints began after the accident.
    24
    contributor. “In those instances where the contributors can be separated, the more lasting
    effect produces greater significance.” Id. at 13. In some matters, the lack of objective
    neurological evidence will be dispositive, but some compensable psychological issues will
    not present neurological symptoms. When dealing with disputes about such issues,
    magistrates and the Commission must give due weight to the technical medical opinions
    of qualified experts. It is not proper to disregard a valid medical diagnosis on the basis that
    there are no objective neurological symptoms if it is well-accepted within the medical
    community that the condition at issue does not present neurological symptoms.
    We agree with plaintiff and the Court of Appeals dissent that Martin, which had
    never been adopted by the courts until now and is not uniformly applied by every
    Commission panel, prevents the fair and consistent adjudication of claims seeking
    compensation for mental injuries under MCL 418.301(2). Martin’s four-factor test has
    disturbed the Legislature’s intent and infiltrated the workers’ compensation arena for far
    too long. It must be corrected.
    V. THE FARRINGTON TEST
    Despite defendant’s argument that Martin is merely a “guide,” the magistrate’s and
    Commission’s analysis below—as is often the case in workers’ compensation cases—
    begins and ends with Martin. This case illustrates the frequent problem of treating Martin
    as dispositive in denying plaintiffs benefits. We conclude that the test in Farrington more
    appropriately reflects the text of MCL 418.301(2).
    Under the Farrington standard, plaintiff must demonstrate that her workplace fall
    and resulting medical problems were “significantly caused or aggravated by employment
    25
    considering the totality of all the occupational factors and the claimant’s health
    circumstances and nonoccupational factors.”           Farrington, 
    442 Mich at 216-217
    .
    Farrington outlined occupational factors that must be weighed when evaluating the
    “significant manner” requirement, including: “the temporal proximity of the [injury] to the
    work experience, the physical stress to which the plaintiff was subjected, the conditions of
    employment, and the repeated return to work after each episode.” 
    Id. at 221
    . Depending
    on the circumstances, other relevant factors might include the natural history of any
    underlying or preexisting condition and whether the condition would have worsened
    naturally in the absence of occupational contributors. Finally, where mental injuries are
    concerned, we agree with the observation in Lombardi that the “significant manner”
    analysis must consider whether “the events occurring at work had more than a minor
    contributing, aggravating, or accelerating effect in the overall psychiatric scheme.”
    Lombardi, 
    199 Mich App at 435
     (emphasis added). However, as we stated in Farrington,
    these factors are “not all inclusive.” Farrington, 
    442 Mich at 221
    . 18 As we ruled in
    Farrington, “[a]fter the enactment of the ‘significant manner’ amendments, these
    occupational factors must now be considered together with the totality of claimant’s health
    circumstances to analyze whether the [mental or physical] injury was significantly caused
    18
    The dissent mischaracterizes the majority’s new test as criticizing the Martin factors,
    while simultaneously permitting their consideration under the clarified Farrington
    standard. However, to reiterate, the majority opinion today specifically takes issue with
    the Martin test being treated as dispositive, not the individual factors themselves. Thus, as
    explained in this part of the opinion, the test being set forth today requires that the totality
    of the circumstances be considered. Under a totality-of-the-circumstances analysis, all
    circumstances are to be considered, which would of course include the Martin factors,
    among the others specified herein.
    26
    by work-related events.” 
    Id. at 221-222
    . Nothing in MCL 418.301(2) suggests that the
    workplace factors must be the most significant cause of a mental disability for it to be
    compensable; there can be more than one significant contributing factor for a compensable
    condition to exist.
    Farrington, as clarified today, advances a test that more closely aligns with the
    statute’s plain text.   Reviewing the totality of the circumstances, including temporal
    proximity and severity, realigns the test with the string of preceding cases that were
    temporarily swallowed by Martin. We are puzzled by the dissent’s objection to the test that
    we adopt today given the acknowledgment that it is a totality-of-the-circumstances standard
    that allows consideration of all relevant facts. Nothing in this opinion precludes the
    consideration of occupational and nonoccupational factors so long as they are not counted as
    a matter of raw mathematics. Our opinion also does not preclude consideration of factors
    concerning mental illness that the medical community has deemed medically relevant.
    Plaintiff’s claims here were rejected on the basis that she could not prove that her
    workplace accident was “the most significant” cause of her mental injuries. While this
    conclusion was reached via the unsound application of Martin, it has yet to be determined
    whether plaintiff’s claims would pass muster when applying the reinstated and clarified
    Farrington totality-of-the-circumstances standard.      There is no dispute that plaintiff
    endured difficult challenges and tragedies in her life prior to the accident. There is also no
    dispute that the fall at issue here was a one-time accident. Therefore, as noted by Judge
    SHAPIRO in his dissent, plaintiff’s single workplace incident could “never constitute more
    than one ‘contributor’ and . . . [could] never outnumber nonoccupational contributors”
    under the Martin test.     Cramer, 338 Mich App at 650 (SHAPIRO, P.J., dissenting).
    27
    Similarly, the single event of falling from a ladder could never compare to the decades of
    abuse plaintiff had sustained before the fall.
    Under the Farrington standard, these factors may still be relevant in considering the
    totality of the circumstances—but they are only part of the inquiry, not the whole inquiry.
    Farrington requires looking beyond the four rigid factors in Martin. The test being set
    forth today in replacement of Martin requires consideration of the factors outlined in this
    opinion when reviewing the totality of the circumstances, including but not limited to, those
    provided in Farrington and Lombardi. However, we do not address today whether plaintiff
    has met her burden. We instead remand this case to the magistrate to review plaintiff’s
    claims under the clarified Farrington standard.
    VI. CONCLUSION
    We hold that the Martin test (1) conflicts with the plain meaning of MCL 418.301(2)
    and (2) is at odds with the principle that a preexisting condition is not a bar to eligibility
    for workers’ compensation benefits. For those reasons, we overrule the four-factor test
    adopted in Martin, and we adopt a clarified version of the test set forth in Farrington in its
    place. We therefore vacate the findings of the magistrate, reverse the judgment of the Court
    of Appeals, and remand this case for further proceedings not inconsistent with this opinion,
    including a redetermination based on the standard set forth in this opinion and MCL
    418.301(2).

    STATE OF MICHIGAN
    SUPREME COURT
    AGNES N. CRAMER,
    Plaintiff-Appellant,
    v                                                            No. 163559

    WAYNE and AMERICAN ZURICH
    INSURANCE COMPANY,
    Defendants-Appellees.
    ZAHRA, J. (dissenting).
    While on an aluminum ladder at work, plaintiff touched a damp towel to an open
    light fixture, causing her to fall to the floor, injuring her shoulder.        The Michigan
    Compensation Appellate Commission (MCAC) affirmed in part and reversed in part the
    magistrate’s decision under the Worker’s Disability Compensation Act (MWDCA): 1 the
    MCAC approved benefits for the treatment of, and wage-loss necessitated by, her shoulder
    injury, 2 but denied benefits for plaintiff’s claim for a mental disability.
    The question before this Court is whether the workplace event aggravated plaintiff’s
    mental condition in “a significant manner” as required under MCL 418.301(2). Plaintiff’s
    treating physicians and psychologist, respectively, diagnosed her in neurological terms
    1
    MCL 418.101 et seq.
    2
    The MCAC also peremptorily corrected and provided plaintiff an additional period to
    recover wage-loss benefits. Defendant has not appealed this decision.
    with post-traumatic stress disorder, and in psychological terms, with conversion disorder. 3
    They believe these disorders account for plaintiff’s reporting of non-epileptic seizures
    (NESs). The diagnoses of these disorders are generally based on a patient’s reported
    history and verified through clinical observation and objective testing. Yet the magistrate
    and the MCAC rejected much of plaintiff’s reported history regarding the workplace
    incident; indeed, plaintiff’s contention that she suffered a severe head injury during the fall
    was not accepted. Also, plaintiff received extensive clinical observation and significant
    objective testing, including 12 days of continuous monitoring, but no NES was indicated.
    To date, not a single medical professional has witnessed plaintiff experience an NES or
    otherwise objectively verified that plaintiff suffered an NES. Given the dearth of evidence,
    any reasonable person would question whether plaintiff’s alleged claims of NESs are
    genuine, let alone significant, and thereby question whether she suffers from PTSD or
    conversion disorder. This alone makes this case a decidedly poor vehicle to consider
    altering longstanding standards addressing the contribution, aggravation, or acceleration of
    a preexisting mental disability.

    “Conversion disorder is a disorder in which a person experiences blindness, paralysis, or
    other symptoms affecting the nervous system that cannot be explained solely by a physical
    illness or injury. Symptoms usually begin suddenly after a period of emotional or physical
    distress or psychological conflict. Conversion disorder is thought to be caused by the
    body’s reaction to a stressful physical or emotional event. Some research has identified
    potential neurological changes that may be related to symptoms of the disorder. Diagnosis
    of Conversion disorder is based on identifying particular signs that are common among
    people with the disorder, as well as performing tests to rule out other causes of the
    symptoms.” Genetic and Rare Diseases Information Center, Conversion Disorder
     (accessed July 14,
    2023) [https://perma.cc/3SZ8-6H4L].

    As such, I believe it to be imprudent to meddle with Martin v Pontiac Sch Dist, a
    unanimous, en banc administrative opinion decided more than 20 years ago. 4 Yet a
    majority of this Court holds the four-factor test laid out in Martin conflicts with MCL
    418.301(2) and is at odds with the principle that a preexisting condition is not a bar to the
    receipt of workers’ compensation benefits. In my view, Martin is entirely consistent with
    this Court’s caselaw interpretating MCL 418.301(2) and is expressly not at odds with the
    principle “that a preexisting condition is not a bar to the receipt of workers’ compensation
    benefits.” Rather, Martin provides sound guidance for determining whether occupational
    factors contributed in a significant manner to a claimant’s existing mental disability.
    In addition, I am not persuaded that the majority’s addition of factors from
    Farrington v Total Petroleum, Inc, 5 resolves any perceived conflict between Martin and
    the text of MCL 418.301(2) or bolsters the principle “that a preexisting condition is not a
    bar to the receipt of workers’ compensation benefits” any more than Martin.               The
    Farrington factors are subsumed in the application of the Martin factors, and when
    relevant, are part and parcel of a proper application of the Martin test. 6

    Farrington v Total Petroleum, Inc, 
    442 Mich 201
    ; 
    501 NW2d 76
     (1993). The Farrington
    factors adopted in the majority opinion are “the temporal proximity of the episodes to the
    work experience, the physical stress to which the plaintiff was subjected, the conditions of
    employment, and the repeated return to work after each episode.” 
    Id. at 221
    .
    6
    The majority embraces the Martin factors in its new test as only permissive; yet it is
    decidedly difficult to imagine an instance in which these factors—“ ‘1) the number of
    occupational and non-occupational contributors [to the disability], 2) the relative amount
    of contribution of each contributor, 3) the duration of each contributor, and 4) the extent of
    permanent effect that resulted from each contributor’ ”—are not fundamental to the
    quantitative and qualitative assessment of the workplace event in relation to a preexisting
    3
    Martin is consistent with MCL 418.301(2). The majority has not cited a single
    workers’ compensation decision that has excluded relevant evidence because it was
    deemed outside of Martin’s four-factor test. To the contrary, many MCAC panels have
    properly utilized Martin for guidance in the interpretation and application of MCL
    418.301(2). Given this fact, we ought not overrule Martin.
    At most, we should clarify and emphasize that Martin expressly provides that its
    four-factor test is not dispositive and that it allows for the consideration of any relevant
    factors, including the Farrington factors if applicable. 7 Thus, there is not much, if any,
    purpose served by the action taken by the Court in this case. The ultimate determination
    the majority now requires under MCL 418.301(2) will, in large part, implicitly rest on the
    Martin factors because they are and will remain the most relevant factors to the ultimate
    determination of a mental disability claim under MCL 418.301(2).
    In sum, the majority opinion has not offered any sound basis to overrule Martin,
    which the MCAC has relied on for over 20 years. I would affirm the Court of Appeals’
    judgment affirming the MCAC’s decision, which in turn, affirmed the magistrate’s denial
    of benefits for plaintiff’s alleged mental disability. For these reasons and those more fully
    developed below, I dissent.

    I. APPLICABLE STANDARDS OF REVIEW
    The majority opinion’s reliance on MCL 418.861a(3) is misplaced because that
    standard only applies to the MCAC’s review of whether the magistrate’s factual findings
    are supported by competent, material, and substantial evidence. Because this case arises
    from a decision of the MCAC, appellate review is controlled exclusively by MCL
    418.861a(14), which provides:
    The findings of fact made by the commission acting within its powers,
    in the absence of fraud, shall be conclusive. The court of appeals and the
    supreme court shall have the power to review questions of law involved with
    any final order of the commission, if application is made by the aggrieved
    party within 30 days after the order by any method permissible under the
    Michigan court rules. [Emphasis added.]
    In Mudel v Great Atlantic & Pacific Tea Co, 8 this Court took up “the task of
    clarifying and definitively setting forth the proper standards of administrative and judicial
    review, to resolve the confusion [then] existing in the law and to further the efficient
    administration of worker’s compensation cases.” 9
    In regard to judicial review, the Court provided an appendix with this basic
    framework:
    The judiciary treats the WCAC’s findings of fact, made within the
    WCAC’s powers, as conclusive absent fraud. If there is any evidence
    supporting the WCAC’s factual findings, the judiciary must treat those
    findings as conclusive. MCL 418.861a(14).
    The judiciary reviews the WCAC’s decision, not the magistrate’s
    decision. MCL 418.861a(14).

    The judicial tendency should be to deny leave to appeal from
    decisions of the WCAC or, if leave is granted, to affirm, in recognition of the
    WCAC’s expertise in this extremely technical area of law. Holden v Ford
    Motor Co, 
    439 Mich 257
    , 269; 
    484 NW2d 227
     (1992).
    The judiciary exercises a very narrow scope of review over the
    WCAC’s decisions, designed to ensure that the WCAC did not misapprehend
    its administrative appellate role in reviewing decisions of the magistrate. 
    Id.
    The judiciary continues to review questions of law involved in any
    final order of the WCAC under a de novo standard of review. DiBenedetto
    v West Shore Hosp, 
    461 Mich 394
    , 401; 
    605 NW2d 300
     (2000).[10]
    The majority opinion’s recitation of facts violates the edict of MCL 418.861a(14),
    as interpreted in Mudel, by premising its conclusions on facts that were not accepted by the
    MCAC. 11 A majority of this Court nonetheless denies that the Court is acting outside the
    boundaries of MCL 418.861a(14), which expressly authorizes this Court to “review
    questions of law involved with any final order of the commission[.]” Questions of law,
    however, are framed by context. 12 And if the context in this case were to frame the question
    of law under plaintiff’s version of the facts, as the majority plainly does, there is no
    interpretation of MCL 418.301(2) under which plaintiff’s claim would be denied. Anyone
    injured at work by being nearly electrocuted to death and then thrown from the fourth step
    of a ladder, striking one’s head on a sink, then falling to the floor injuring both a shoulder
    and head again, is all but guaranteed compensation. But MCL 418.861a(14) does not
    authorize this Court to review de novo the factual assertions of the litigants. Rather, MCL

    11
    Application of the erroneous standard of review and the failure to give deference to the
    factual determinations of the MCAC are reason enough not to meddle with the Martin

    Id.
    II. FINDINGS OF FACTS MADE BY THE COMMISSION
    Plaintiff, Agnes Cramer, worked for defendant Transitional Health Services of
    Wayne, a nursing care facility. On February 8, 2012, plaintiff received an electrical shock
    arising out of and in the course of her employment with defendant, which precipitated her
    fall from a ladder and injury to her right shoulder. Plaintiff’s husband drove her to
    Oakwood Annapolis Hospital, where she was assessed, and showing no indications of
    injury, released. Medical records contained a specific note that plaintiff denied any
    headaches, dizziness, or visual problems. The records did not reflect that she appeared
    confused or presented cognitive problems, nor was there any mention of a loss of
    consciousness. There was no indication that her hand required treatment for an electrical
    injury. At trial, plaintiff claimed that these medical records were wrong. Yet she also
    agreed with the hospital’s assessment and plan upon discharge, which stated, “after the
    whole assessment and work up, therefore it appears patient has escaped from any major
    injury or trauma to herself, [and] will be going home most probably.”
    Plaintiff returned to work two days later; she claimed to feel dizzy and disoriented
    and left. Plaintiff claims that she sought an opinion from her family doctor, who allegedly
    diagnosed her with a concussion.       Nonetheless, plaintiff’s medical records did not
    document that plaintiff appeared confused or presented with cognitive problems, nor was
    7
    there any mention of a loss of consciousness. Plaintiff was referred to the Michigan
    Institute for Neurological Disorders (MIND). She was first evaluated there on March 7,
    2012, where for the first time she reported headaches and cognitive dysfunction stemming
    from a closed head injury on February 8, 2012. On March 15, 2012, she underwent an
    EEG, which was normal. On April 16, 2012, plaintiff completed an at-home ambulatory
    EEG, which was normal. The MCAC found, “During that period of treatment plaintiff
    underwent a two-day ambulatory home EEG that was interpreted as normal despite
    plaintiff and her caregiver reporting six seizure events.”
    Notably, during MIND’s evaluation, plaintiff had also gone to the Henry Ford
    Hospital on April 1, 2012, claiming that she had been experiencing “seizures” since she
    was “electrocuted” on February 8, 2012, and self-reporting that she had been having
    persistent twitches. The following day, plaintiff visited Chicago and went to the emergency
    room at the Alexian Brothers Medical Center in Elk Grove, Illinois, with complaints of
    seizures. Her test results again were normal, and she did not have any seizure episodes
    from admission to discharge. She admitted to having two glasses of wine, yet her medical
    records indicate a very substantial blood-alcohol content of .24%.
    After completing her two-day ambulatory, home EEG with MIND on April 16,
    2012, which was normal, plaintiff felt it necessary to visit the emergency room at the
    Garden City Hospital, again claiming that she had suffered seizures. Her test results were
    again normal, though medical records reflected that she might be having NESs. The
    records also reflected a blood-alcohol content of .087. She was informed that she should
    not be drinking alcohol.
    8
    On June 25, 2012, plaintiff was admitted to the Henry Ford Epilepsy Monitoring
    Unit for diagnostic monitoring. No seizures or spells were recorded during two weeks of
    continuous video-EEG monitoring, including 12 days without antiseizure medications.
    She was subsequently discharged.
    Plaintiff was again seen on July 1, 2014, and reported the February 8, 2012 incident
    as a “near fatal electrocution.” She reported suffering terrible flashbacks when there is
    thunder and lightning, loud noises, or bright flashing lights. She sought treatment for an
    injured rib she claimed to have suffered by falling into a fireplace during a seizure two days
    before. She also reported that her previous husband had physically and emotionally abused
    her and that after she obtained a divorce, her mother said to her, “You’re dead to me now.”
    On July 4, 2014, plaintiff overdosed on prescribed anti-epileptic medications, and medical
    records reflect that she was feeling lonely and isolated since being abandoned by her family
    and living apart from her friends in Indiana.
    Plaintiff’s treating doctors diagnosed her with PTSD from the February 8, 2012
    incident and opined that she was suffering from NESs, meaning that her seizures were
    brought on, not by any physical brain abnormality, but by stress. When questioned about
    the significance of the February 8, 2012 incident, plaintiff’s treatment professionals
    provided similar responses. The Court of Appeals majority explained in regard to one
    expert:
    Dr. [Mariana V.] Spanaki-Varalas concluded that plaintiff’s accident at work
    “led to anxiety” and that she therefore “developed [PTSD].” The doctor
    testified, “The patient had none of those episodes before the insult, and then
    she progressively developed those up to the point that she had convulsive
    episodes.” Dr. Spanaki-Varalas stated that the workplace incident “was the
    starting point of [plaintiff’s] symptoms” and was a significant factor that led
    9
    to PTSD and related [NESs]. Dr. Spanaki-Varalas admitted that she was not
    in the best position to determine the “cause or etiology of what ultimately
    was [the] diagnosis of PTSD leading to” NESs and that this was best left to
    other professionals.[13]
    As to Andrea J. Thomas, plaintiff’s treating psychologist, the Court of Appeals
    majority observed
    that plaintiff had NESs because they were “diagnosed during her stay in the
    [epilepsy] unit,” and she determined that plaintiff had PTSD by taking
    plaintiff’s history. Thomas said that plaintiff had stressors earlier in her life,
    but the workplace incident made “the situation that much worse” and
    contributed to or caused her NESs and PTSD.[14]
    Last, as to Dr. Gregory Barkley, the Court of Appeals majority noted he
    stated that plaintiff had been able to cope with “the other things that had
    happened to her,” but the workplace incident “became the straw that broke
    the camel’s back.” He admitted that he was relying on plaintiff’s provided
    information in making his conclusions.[15]
    Given that NESs can and are often diagnosed based on previous physical, sexual, or
    mental abuse, defendant sought to prove that the traumatic and stressful events in her
    personal life were the root cause of her current mental condition. 16 As the Court of Appeals

    16
    The majority opinion claims it is unnecessary to focus on plaintiff’s various family-
    related hardships that she experienced before her workplace fall. This is a confounding
    criticism. After all, this is a claim under MCL 418.301(2), which relates to aggravation of
    a pre-existing mental condition. And plaintiff did testify that, “what happens when you
    have a severe trauma in your life, there are things that come flooding back into your head.
    And it’s hard for you to push them away because it’s like a dam being burst. Things that
    were taken care of, resolved, issues that no longer were issues you think about again.”
    While the majority opinion correctly observes that “plaintiff’s employment-related
    10
    majority aptly explained, “plaintiff had an extremely traumatic history, including 19 years
    of horrific abuse at the hands of her ex-husband. The defense posture was that plaintiff’s
    mental issues stemmed primarily from this history and that plaintiff was also exaggerating
    her claims of disability.” 17
    Defendant provided expert support from Manfred Greiffenstein, a licensed
    psychologist. The Court of Appeals summarized his testimony as follows:
    Greiffenstein met with plaintiff and conducted a neuropsychological
    evaluation of plaintiff. Greiffenstein spoke with plaintiff and reviewed
    several imaging scans. Specifically, Greiffenstein reviewed an MRI of
    plaintiff’s brain that was normal and an EEG that showed no epileptiform
    activity. Greiffenstein concluded on the basis of plaintiff’s medical history
    that her apparent symptoms “waxed and waned in dramatic fashion,” with
    diagnoses added and dropped accordingly.                    Plaintiff was having
    “psychogenic non-epileptic seizures” (PNESs). Greiffenstein stated that
    such seizures “are usually caused by the intersection of an underlying
    personality disorder and unusually stressful circumstances.” He said that the
    causes could be in the distant past or “in the here and now.” He added, “[T]he
    theory is that [PNESs] act to control the environment in persons who
    otherwise have inadequate coping skills.” PNESs are “a complex behavior
    triggered by stress that mimics seizures.” Plaintiff had been in a physically
    and sexually abusive marriage, was still in contact with her ex-husband, was
    estranged from some of her children, and maintained a contentious
    relationship with her mother. Accordingly, Greiffenstein found that “the
    stressors in [plaintiff’s] life are not at one time or at [sic] one off event. They
    are recurrent features of her daily existence.”
    Greiffenstein reported that plaintiff “used exaggerated language to
    describe the symptoms and their functional impact on her life.” After
    administering several tests, Greiffenstein concluded that plaintiff’s results
    complaints began after the accident,” her mental disability claim must still be evaluated
    under all the relevant circumstances. (Emphasis omitted.) Moreover, plaintiff’s lack of a
    previous diagnosis for mental illness does not mean that plaintiff would not have been
    diagnosed with mental illness had she sought treatment before the workplace event.
    17
    Id. at 610.
    11
    were consistent with someone “grossly overstating” disability-related
    complaints. He noted that plaintiff “did not make the types of errors
    associated with focal or diffuse brain disease” and stated that, “[b]ased on
    negative brain scans and a chart history of waxing and waning complaints,
    the evidence favors histrionic personality” or “Undifferentiated Somatoform
    Disorder.” He said, “This is a form of mental illness characterized by prolific
    but medically unexplained symptoms, where personality and situational
    factors are the root cause.” Greiffenstein stated that it is difficult to
    distinguish this illness from “malingering,” or faking, and that this difficulty
    was present in plaintiff’s case, because she had presented elements of such
    faking. Greiffenstein also gave a diagnosis of “conversion disorder.” When
    asked to define this, he stated:
    Conversion disorder is the modern term for what used to be
    called chronic hysteria, meaning a psychologically disturbed
    patient whose mental illness takes the form of medically
    unexplained symptoms. In the case of conversion disorder, the
    medically unexplained symptoms refer to the central nervous
    system, meaning they might mimic disorders of the central
    nervous system but on further medical testing there is no lesion
    of the central nervous system found. These are typically
    persons who are histrionic and give colorful and dramatic
    medical histories that ultimately don’t add up or make sense.
    Greiffenstein concluded that plaintiff was able to work. He stated, “Mental
    health services are presently indicated for interpersonal conflict. These are
    personal problems that pre-date the accident.” Greiffenstein said that
    plaintiff’s “symptom claims are best understood as an interaction between a
    disturbed personality and psychosocial stressor.” This personality issue
    would have been present before plaintiff even began working at Transitional
    Health Services.[18]
    Another defense expert, Dr. Wilbur J. Boike, agreed and stated:
    It remains my strong opinion that [plaintiff] has no neurological impairment
    or disability. So long as her subjective complaints provoke yet evermore
    evaluation and treatment by medical care providers, it is likely that
    [plaintiff’s] complaints will escalate over time. Given her complaints
    regarding comments reportedly made to her concerning the possibility of
    18
    Cramer, 338 Mich App at 611-612 (alterations in original).
    12
    future “Parkinson’s” disease, I would not be at all surprised if this will be the
    next “presentation” of her “illness.”
    I strongly recommend that medical care providers discontinue the
    current practice of reacting to every new symptom as a manifestation of some
    serious underlying illness. I actually believe [plaintiff’s] long-term
    prognosis is excellent. I believe it is likely that she will completely resolve
    all of her current “difficulties” once there is resolution of whatever legal
    proceedings are underway at this time. I do not believe [plaintiff] requires
    any additional evaluation or treatment of her ongoing complaints.
    I strongly doubt that she is actually experiencing headaches at this
    time.[19]
    The magistrate issued a 43-page decision. After a detailed summary of the evidence
    presented at trial, the magistrate observed that “[t]here was no objective medical testimony
    that plaintiff sustained a disabling injury to her head, headaches, right hand and wrist.”
    The magistrate concluded that, “[b]ecause plaintiff’s seizures and headaches are unrelated
    to the incident on February 8, 2012, [plaintiff] has failed to establish a limitation in her
    wage earning capacity in work suitable to her qualifications and training.” (Emphasis
    added.)
    The magistrate accepted “plaintiff’s claim that she injured her shoulder in the fall
    based in part on the statement by Dr. Greiffenstein that the emergency room records are
    usually the most accurate records because honesty and self-preservation intersect at that
    time.” Accordingly, the magistrate found that “plaintiff was disabled due to the injury to
    her right shoulder from the date of the incident on February 8, 2012 through April 12,
    2013 . . . .” 20 Plaintiff appealed in the MCAC, which for all intents and purposes, affirmed
    19
    Comma omitted.
    20
    The magistrate found, “There was no evidence that plaintiff made a good faith effort to
    find employment.” Thus, the magistrate rejected plaintiff’s disability wage-loss claim.
    13
    the magistrate’s findings on the merits. Plaintiff sought leave to appeal in the Court of
    Appeals, which entered an order remanding “this matter to the Board of Magistrates for
    the limited purpose of allowing the magistrate to determine whether plaintiff is entitled to
    a discretionary award of attorney fees on unpaid medical benefits.” 21 The order also stated
    “[i]n all other regards, the application for leave to appeal is DENIED for lack of merit in
    the grounds presented.” 22
    Plaintiff sought leave to appeal in this Court, and we issued the following order:
    Pursuant to MCR 7.305(H)(1), in lieu of granting leave to appeal, we remand
    this case to the Court of Appeals for consideration, as on leave granted, of
    whether: (1) the Michigan Compensation Appellate Commission correctly
    concluded that the magistrate properly applied the four-factor test in Martin
    v Pontiac Sch Dist, 2001 Mich ACO 118, lv den 
    466 Mich 873
     (2002), and
    the standard in Yost v Detroit Board of Education, 2000 Mich ACO 347, lv
    den 
    465 Mich 907
     (2001); (2) the Martin test is at odds with the principle
    that a preexisting condition is not a bar to eligibility for workers’
    compensation benefits and conflicts with the plain meaning of MCL
    418.301(2); and (3) the Michigan Compensation Appellate Commission
    correctly concluded that the magistrate’s lack of causation conclusion was
    supported by the requisite competent, substantial, and material evidence
    utilizing the proper standard of law. In all other respects, leave to appeal is
    denied, because we are not persuaded that the remaining question presented
    should be reviewed by this Court.[23]
    The MCAC, however, reversed the magistrate’s finding in this regard, instead concluding
    that, “[c]ontrary to the finding of the magistrate, the unrebutted evidence supports a finding
    that plaintiff did engage in a good faith job search, such that she is entitled to receive wage
    loss at the stipulated weekly rate of $390.22 from February 8, 2012, through April 12,
    2013.” These findings are not challenged here.
    21

    Appeals, entered August 16, 2019 (Docket No. 347806).

    505 Mich 1022

    14
    On remand, a divided panel of the Court of Appeals affirmed. The Court of Appeals
    majority first held that “[t]here was evidence to support the MCAC’s decision . . . , and no
    indication that the MCAC somehow misapplied the governing legal standards.” 24 The
    panel majority then held that the MCAC properly reviewed the magistrate’s application of
    Martin and Yost and “conclude[d] that the MCAC did not err by concluding that the
    magistrate’s conclusions regarding the Martin and Yost factors were supported by
    competent, material, and substantial evidence.” 25 Last, the majority held:
    We cannot conclude that the Martin test conflicts with the plain
    language of MCL 418.301(2) when it essentially conforms with the Supreme
    Court’s own guidance regarding how to apply that statute—i.e., it provides
    for a comparison of nonemployment and employment factors. Indeed,
    analyzing the number of stressors, the relative amount they contribute to a
    condition, the various stressors’ duration, and the extent of the stressors’
    permanent effect essentially implements the language from Gardner [v Van
    Buren Pub Sch, 
    445 Mich 23
    ; 
    517 NW2d 1
     (1994), overruled on other
    grounds by Robertson v DaimlerChrysler Corp, 
    465 Mich 732
     (2002)] and
    Farrington. A worker with a preexisting illness can obtain benefits as long
    as an analysis of pertinent factors shows that a work stressor contributed to,
    aggravated, or accelerated the illness in a significant manner.[26]
    The Court of Appeals majority would later add, “[w]hile we do not conclude that
    there are grounds to overturn Martin, we acknowledge that magistrates and the MCAC
    should always remain cognizant that there can be more than one contributor or group of
    24

    15
    contributors affecting a mental disability ‘in a significant manner’ and that the Martin test
    is only a guide to aid in the fact-finding process.” 27
    Plaintiff again sought leave to appeal in this Court. We granted the application and,
    similarly to our remand order to the Court of Appeals, we directed the parties to address
    the following:
    (1) whether the four-factor test in Martin v Pontiac Sch Dist, 2001 Mich ACO
    118, lv den 
    466 Mich 873
     (2002), (a) is at odds with the principle that a
    preexisting condition is not a bar to eligibility for workers’ compensation
    benefits, and (b) conflicts with the plain meaning of MCL 418.301(2); and
    (2) assuming that Martin provides the appropriate test, the parties shall
    address whether, on this record, the Court of Appeals erred in affirming the
    Michigan Compensation Appellate Commission’s conclusion that the
    magistrate properly applied Martin, as well as the standard in Yost v Detroit
    Bd of Ed, 2000 Mich ACO 347, lv den 
    465 Mich 907
     (2001).[28]
    III. ANALYSIS
    A. MARTIN SHOULD NOT BE DISTURBED
    MCL 418.301(2) provides:
    Mental disabilities and conditions of the aging process, including but
    not limited to heart and cardiovascular conditions and degenerative arthritis,
    are compensable if contributed to or aggravated or accelerated by the
    employment in a significant manner. Mental disabilities are compensable if
    arising out of actual events of employment, not unfounded perceptions
    thereof, and if the employee’s perception of the actual events is reasonably
    grounded in fact or reality.
    To determine whether a workplace event contributed, aggravated, or accelerated a
    mental disability in “a significant manner,” the Martin test provides that the fact-finder
    27
    Cramer, 338 Mich App at 643.
    28
    Cramer v Transitional Health Servs of Wayne, 
    509 Mich 871
     (2022).
    16
    consider four non-exclusive factors: “1) the number of occupational and non-occupational
    contributors [to the disability], 2) the relative amount of contribution of each contributor,
    3) the duration of each contributor, and 4) the extent of permanent effect that resulted from
    each contributor.” 29
    The majority criticizes the Martin test as it, “in both theory and practice, exhibits
    bias against finding for plaintiffs and is problematic for three reasons. First, Martin’s test
    does not reflect the statutory language.” “Second, as evidenced by the magistrate, the
    Commission, and the Court of Appeals panel here, Martin is being treated as a bright-line
    test, as opposed to the ‘guide’ it was intended to be.” And third, “the limited factors
    themselves often tip the scales in favor of noncompensability.” 30
    None of the majority’s criticisms of Martin is compelling. The majority’s first
    criticism relies almost exclusively on an MCAC panel’s divided opinion in Taig v Gen
    Motors Corp, 31 which declined to rely on Martin, asserting that it “creates a legal standard
    far a field [sic] from the one envisioned by MCL 418.301(2).” The Taig majority’s view
    of Martin is highly flawed, not only because it reads Martin with a jaundiced eye, but
    because its understanding of MCL 418.301(2) is directly contrary to this Court’s decisions
    in Farrington and Gardner. Taig’s majority asserted that “if the employee’s (here,
    emotional) condition is aggravated ‘in a significant manner’ by the conditions of
    
    29 Martin, 2001
     Mich ACO 118, p 16.
    30
    In discussing Martin’s factors, the majority opinion concludes that “[f]actors one and
    three are most problematic and inherently biased against plaintiffs.”
    31
    Taig v Gen Motors Corp, 2006 Mich ACO 134, p 11.
    17
    employment to produce an injury, nothing in MCL 418.301(2) allows the identification of
    some other factor, even if non-work-related and even if significant, to refute the causal
    connection.” 32     This is simply not true: Farrington stated that an “injury must be
    significantly caused or aggravated by employment considering the totality of all the
    occupational factors and the claimant’s health circumstances and nonoccupational
    factors.” 33 Indeed, Farrington noted that nonoccupational factors relevant to a preexisting
    heart condition, include, for example, age, weight, diet, previous cardiac ailments or
    injuries, genetic predispositions, and the claimant’s consumption of alcohol and use of
    tobacco or other drugs. 34 Likewise, Gardner expressly states that “[t]he analysis [under
    MCL 418.301(2)] must focus on whether actual events of employment affected the mental
    health of the claimant in a significant manner. This analysis will, by necessity, require a
    comparison of nonemployment and employment factors.” 35 This comports with basic
    common sense: to decide whether the injury’s contribution was significant, one must also
    consider the significance of other contributing factors. For this reason alone, the Taig
    opinion is poorly reasoned and should be rejected.
    But there are more reasons to disregard the majority opinion in Taig, which also
    criticizes Martin over concerns that a “pre-existing condition will always place a figurative

    18
    finger on the scale and militate against a conclusion of work relationship.” 36 This is
    precisely how the Legislature intended MCL 418.301(2) to operate, which is why MCL
    418.301(2) requires a significant work contribution in this class of cases as opposed to all
    other classes of cases requiring any work contribution. While Taig’s majority apparently
    disagrees with MCL 418.301(2) as a policy, policy-making is primarily a legislative
    function. Here, the language of MCL 418.301(2) couldn’t be clearer. The Legislature
    made it more difficult for claimants to recover for, among other types of claims, mental
    disabilities.
    The Taig majority opinion then claimed that “Martin substitutes for an analysis of
    the record a default rule that a ‘subjectively significant event’ cannot constitute a legally
    significant contribution.” 37 Even if that claim had any merit in 2006 when Taig was
    decided (which it did not) and held true for a period of time, the Legislature amended MCL
    418.301(2) in 2011 38 to mandate that which was already obvious: requiring that an
    “employee’s perception of the actual events is reasonably grounded in fact or reality.” By
    law, Taig’s so-called “subjectively significant event” is no longer a sustainable claim when
    contribution to a preexisting mental disability lacks objective proof that the event is
    significant. Taig was never sound, likely prompting the Legislature to later amend the
    statute, in part, to put an end to claims solely based on a “subjectively significant event.”

    .
    19
    A majority of this Court also clings to another misguided criticism of Martin from
    Taig, which asserted:
    [I]f the work-related conditions are found not to have aggravated the
    condition “in a significant manner” because some other condition is more
    significant, this is legal error because it alters the legislative scheme of “in a
    significant manner” into requiring the employment conditions be “the most
    significant” cause of the injury before it will be found to be compensable.
    This is precisely the kind of shift in policy that is not the role of the
    administrative agency to make.[39]
    This claim is wholly flawed. Martin does not hold that a more-significant nonoccupational
    condition precludes an occupational condition from aggravating a preexisting mental
    disability in a significant manner. Rather, Martin rejected this assertion by likening its
    “evaluation to Judge Learned Hand’s explanation in United States v Carroll Towing, 159
    F2d 169 ([CA 2,] 1947), which defined ‘reasonable conduct’ as that which produces a
    burden of alternative conduct greater than the product of the probability and gravity of its
    detrimental consequences.” 40 Martin explained that its evaluation “defies mathematic
    calculation.” 41 Martin then elaborated on this point, borrowing from Scott v Broder Bros
    Co, Inc: 42
    “If, as a matter of objective fact, a workplace event is a significant contributor
    to a claimant’s mental disability, such disability is compensable, even if the
    same event would have had little or no impact on an ordinary or reasonable
    person.

    It is for this reason that pre-existing frailties cannot act as a bar to
    recovery. A pre-existing condition which makes a claimant more susceptible
    to mental injury does not act as a bar to benefit entitlement if workplace
    injury causes the claimant to become disabled. Corbett v Charter Township
    of Plymouth . . . .[43] It is entirely possible that an employee with pre-existing
    mental complaints might become mentally disabled because of a workplace
    event that, for this particular employee, was so weighty as to become a
    significant source of the mental disability. But there is an enormous
    difference between saying that a pre-existing frailty cannot act as a bar to
    recovery, and saying that it should not be considered.”[44]
    This explanation refutes any assertion that Martin interpreted the phrase “in a significant
    manner” to be understood as “the most significant manner.” 45

    Many MCAC decisions also refute this assertion, and many of these decisions consider
    the temporal proximity of the episodes to the work experience. Yahia v Omega Indus, Inc,
    2005 Mich ACO 80, pp 3, 11 (affirming an open award for mental disability, stating,
    “Aided by the magistrate’s Martin review, we are convinced that his decision pertaining to
    psychiatric disability is supported by competent, material and substantial evidence on the
    whole record” and agreeing with the magistrate that plaintiff’s loss of custody of his child
    from a previous marriage was a significant nonwork-related factor); Traylor v Wayne Co,

    work connection; her pre-existing personality disorders, her prior treatment, her past
    traumatic experiences (possible rape/possible suicide attempt) and, most importantly, the
    murder/suicide of her sister/brother-in law being the out-of-work factors. Numerically,

    depression and mental treatment, indicate such predisposition”); Dawkins v Wal Mart

    The majority opinion next claims Martin is being treated as a bright-line test, as
    opposed to the “guide” it was intended to be. But it is far from clear that this is indeed the
    case. The language of Martin made clear:
    [W]e avoid creating a bright-line test or checklist. Instead, we propose
    factors which concentrate the analysis on the fundamental evidence
    regarding increased contribution. We prefer factors because factors differ
    from elements. Each element requires a preponderance of proof. Factors do
    not require such proof. Rather, overwhelming proofs regarding one factor
    can overcome the absence of proof regarding another factor.[46]
    It is true that Martin later said in its decision that “we have adopted a definition for
    significant contribution that can be satisfied only when a four-factor test is met.” 47 But this
    single, then-unnecessary and now-unfortunate, mention of the word “only” viewed in
    magistrate balanced the work-related factors and the non-work-related factors and
    concluded that plaintiff’s mental disability had been precipitated ‘in a significant manner’
    by the injury at work” and noting that “the record does not establish that [a traumatic auto
    accident involving a significant head injury that] occurred in 1982 was part of a work-related
    journey”); Raguckas v Mich Dep’t of Corrections 2009 Mich ACO 82, pp 7-8 (affirming a

    contributors have not contributed too much to plaintiff’s major depression since she had
    coped many years without having major depression until she was transferred to Chelsea
    and began experiencing work-related difficulties’ ”).

    hindsight from a lengthy en banc agency decision does not plausibly negate that which
    Martin had previously made clear: the factors are not intended to create a rigid test.
    Martin has never precluded the consideration of evidence “in addition to medical
    testimony, [relating to] ‘potentially significant factors in the causal equation,’ ” including:
    “the temporal proximity of the [injury] to the work experience, the physical stress to which
    the plaintiff was subjected, the conditions of employment, and the repeated return to work
    after each episode.” 48 Farrington recognized that the crux of Martin turned on the
    Legislature’s hope that, “[a]fter the enactment of the ‘significant manner’ amendments,
    [applicable] occupational factors must now be considered together with the totality of
    claimant’s health circumstances to analyze whether the [health condition] was significantly
    caused by work-related events.” 49 Martin maintained that in workers’ compensation
    proceedings, “the totality of claimant’s health circumstances [must be examined to
    determine] whether the [plaintiff’s disability] was significantly caused by work-related
    events.” 50

    . Oddly, the same criticism the majority lodges against
    Martin in terms of “contradiction” can as easily be lodged at Farrington: Farrington listed
    potential factors in the opinion and later stated that the same potential factors must be
    addressed. This minor discrepancy does not suggest the totality of the circumstances can
    be ignored. Rather, a reasonable reading of Farrington is that all applicable factors must
    be addressed.

    I find puzzling that the majority opinion cites cases that simply reiterate the point
    the Court of Appeals’ majority made clear: Martin is not a bright-line test. 51 Even more
    confounding is plaintiff counsel’s understanding of Martin. At argument, plaintiff’s
    counsel engaged in the following colloquy:
    Justice VIVIANO: I mean there is no case that says, if there is four
    outside contributors and one, one, workplace contributing factor, that’s
    enough, is there? Is there any case that holds that?
    Roger Kline [plaintiff’s counsel]: Did you say four outside and one at
    work, . . . well that’s what Martin says.
    Justice VIVIANO: So Martin says just count and if the count is more
    outside than inside then the analysis is over? That’s your, that’s your
    interpretation of Martin?
    [Plaintiff’s counsel]: Yeah.
    Justice VIVIANO: Really?
    [Plaintiff’s counsel]: Yeah that’s my interpretation.
    Justice VIVIANO: So, when Martin says look at all these other factors,
    look at factors we didn’t list, no factor alone is conclusive. No, it didn’t mean
    any of those things, it only meant count them and if the accounting is more
    outside than inside you’re done.
    [Plaintiff’s counsel]: That’s how I read it.
    If the understanding of plaintiff’s counsel were correct, I would agree that Martin is
    a bright-line test, which I understand to mean “[a] legal rule of decision that tends to resolve
    issues, esp. ambiguities, simply and straightforwardly, sometimes sacrificing equity for
    51
    Bolden v DaimlerChrysler Corp, 2006 Mich ACO 170, p 7; Dortch v Yellow Transp,
    Inc, 2007 Mich ACO 21, p 4; Jones-Stott v Henry Ford Hosp, 2007Mich ACO 31, p 6.
    24
    certainty.” 52 But the argument of plaintiff’s counsel that Martin only requires a tally of
    factors cannot be taken seriously. Over the past 20 years, Martin has only once been called
    into question by the MCAC, in Taig, a divided agency opinion. This single case does not
    support the false narrative that has been suggested, which the majority opinion accepts
    without proof, that some magistrates arbitrarily apply Martin while others do not. 53 Even
    if true, overruling Martin is clearly not a measured response when this Court can simply
    reiterate, as the Court of Appeals did, that Martin is not a bright-line test. The only aspect
    of the majority opinion that suggests an improper bright-line test is the notion of a
    workplace event that amounts to the “straw that broke the camel’s back.” I agree that this
    metaphorical approach is often inapt because it suggests the workplace event was a minor
    or trivial event, which may or may not be the case. Yet Yost makes clear that the weight
    of the workplace event must be evaluated, regardless of whether a plaintiff’s expert
    mentions the metaphor and the likelihood that a defendant will then rely on the metaphor
    to argue that the workplace event was not significant. 54 This aspect of Yost, however, is
    not implicated in this case. The magistrate here did not “apply” a “last event” analysis and
    52
    Black’s Law Dictionary (11th ed), p 1594 (defining “bright-line rule”).
    53
    Indeed, while the majority makes many empirical assertions about how the factors work
    in practice, it provides no citations or other proof to support the assertions. See, e.g., ante
    at 22 (stating, without citation, that “the limited factors themselves often tip the scales in
    favor of noncompensability”); ante at 24 (stating, without attribution or citation to
    authority, “Like the first, [the third] factor tends to generate findings of noncompensability
    any time a plaintiff suffers from a longstanding preexisting condition.”).
    54
    Yost, 2000 Mich ACO 347, p 2.
    25
    instead criticized plaintiff’s expert because he introduced the metaphor yet refused to
    consider the weight of the nonoccupational factors.           In other words, the magistrate
    understood the obligation requires an assessment of “the relative amount of contribution of
    each contributor[.]” 55 The magistrate stated:
    There was no testimony that Dr. Barkley, Dr. Spanaki-Varalas and Ms.
    Thomas attempted to quantify the stressors from the work incident to the
    other stressors in plaintiff’s life. Ms. Thomas said plaintiff’s post-traumatic
    stress disorder and conversion disorder was significantly caused or
    contributed to by the accident at her workplace; however she appeared to
    contribute little significance to plaintiff’s non-occupational stressors. Ms.
    Thomas merely stated plaintiff had some issues earlier in her life but she was
    doing fairly well with everything prior to the workplace incident.
    Dr. Barkley made no comparison between plaintiff’s occupational and
    non-occupational stressors. He said plaintiff had various traumatic
    experiences in life and had been able to cope with the other things that had
    happened to her but the work injury was the straw that broke the camel’s
    back. It was Dr. Barkley’s opinion that the fact that plaintiff did not have the
    [symptoms] before the injury and now has them appears to be causally
    related.
    Dr. Spanaki-Varalas also did not make a comparison between
    plaintiff’s occupational and non-occupational stressors. Dr. Spanaki-Varalas
    said the injury brought up or maximized plaintiff’s previous stressors. She
    said plaintiff had stressors but she was coping relatively well until the
    electrical shock and the fall.
    Dr. Barkley, Dr. Spanaki-Varalas and Ms. Thomas all said the
    incident of February 8, 2012 caused plaintiff’s post-traumatic stress disorder
    and conversion disorder. They did not compare the non-occupational
    stressors to the occupational stressors in plaintiff’s life to determine which
    stressors were the more substantive contributors.

     Mich ACO 118, p 16.
    26
    The MCAC did not commit error by accepting the magistrate’s determination that
    plaintiff’s expert improperly relied on a “straw that broke the camel’s back” analysis. None
    of the majority’s criticisms of Martin is sound, and Martin should be retained.
    B. THE NEW TEST ADOPTED BY THIS COURT IS UNECCESSARY AND NOT
    HELPFUL
    The majority opinion concludes:
    Under the Farrington standard, [the Martin] factors may still be
    relevant in considering the totality of the circumstances—but they are only
    part of the inquiry, not the whole inquiry. Farrington requires looking
    beyond the four rigid factors in Martin. The test being set forth today in
    replacement of Martin requires consideration of the factors outlined in this
    opinion when reviewing the totality of the circumstances, including but not
    limited to, those provided in Farrington and Lombardi [v William Beaumont
    Hosp (On Remand), 
    199 Mich App 428
    ; 
    502 NW2d 736
     (1993)].
    The majority in essence improperly criticizes the Martin factors only to permit those
    same factors in its new test. 56 The same reasons that the majority has criticized the Martin
    factors will be the same reasons that later claimants will rely on to challenge the Farrington
    standard. And Martin explicitly allows the consideration of the Farrington factors. The
    new test, therefore, is not necessary.
    Moreover, Farrington is a case involving a heart attack while Martin is a case that
    only considered mental disability. Apparently—and without much, if any, explanation—
    the majority asserts that the addition of the Farrington factors will be helpful. This is an
    odd assertion given that the Farrington factors were not drawn from a mental disability
    56
    The majority opinion expressly denies criticizing the Martin factors, yet states that
    Martin “[f]actors one and three are most problematic and inherently biased against
    plaintiffs.”
    27
    claim. Instead, they were first drawn from Kostamo v Marquette Iron Mining Co, a 1979
    decision of this Court that, like Farrington, addressed a heart attack claim, 57 in which focus
    on “the temporal proximity of the . . . episodes to the work experience, the physical stress
    to which the plaintiff was subjected, the conditions of employment, and the repeated return
    to work after each episode,” 58 and consideration of these factors in a physical injury case
    makes sense. 59 But as applied to claims of mental disability cases, the majority’s resolution
    will only create confusion by requiring the consideration of factors that, like in this case,
    are not particularly relevant to a mental disability claim. The majority’s new test does not
    resolve any inconsistency. Rather, the majority simply applies an ineffective Band-Aid
    that obscures the inconsistency the majority wrongly believes existed under the Martin test.
    Likewise, I am not persuaded that addition of the Farrington factors bolsters the
    proposition “that a preexisting condition is not a bar to the receipt of workers’
    compensation benefits” any more than Martin. Given that Martin plainly provides that its
    four-factor test is not exclusive and allows for the consideration of any relevant factors,
    including the Farrington factors if applicable, there is not much, if any, purpose served by
    the majority’s opinion. The ultimate determination this Court now requires under MCL
    418.301(2) still rests on the Martin factors because they are, and will remain, the most
    relevant factors to the ultimate determination of a mental disability claim under MCL

    418.301(2). In contrast, in most mental disability cases, the Farrington factors will still be
    viewed as peripheral, at best supplementing the Martin factors because, like in this case,
    the Farrington factors are not highly relevant.
    Amicus AF Group draws our attention to a far better list of relevant factors (set forth
    by the Mayo Clinic), all or any of which Martin allows to be considered in a mental
    disability case:
    Mental illnesses, in general, are thought to be caused by a variety of
    genetic and environmental factors:
    • Inherited traits. Mental illness is more common in people whose
    blood relatives also have a mental illness. Certain genes may
    increase your risk of developing a mental illness, and your life
    situation may trigger it.
    • Environmental exposures before birth. Exposure to
    environmental stressors, inflammatory conditions, toxins, alcohol
    or drugs while in the womb can sometimes be linked to mental
    illness.
    • Brain chemistry. Neurotransmitters are naturally occurring brain
    chemicals that carry signals to other parts of your brain and body.
    When the neural networks involving these chemicals are impaired,
    the function of nerve receptors and nerve systems change, leading
    to depression and other emotional disorders.
    * * *
    Certain factors may increase your risk of developing a mental illness,
    including:
    • A history of mental illness in a blood relative, such as a parent or
    sibling
    • Stressful life situations, such as financial problems, a loved one’s
    death or a divorce
    • An ongoing (chronic) medical condition, such as diabetes
    29
    • Brain damage as a result of a serious injury (traumatic brain
    injury), such as a violent blow to the head
    • Traumatic experiences, such as military combat or assault
    • Use of alcohol or recreational drugs
    • A childhood history of abuse or neglect
    • Few friends or few healthy relationships
    • A previous mental illness[60]
    These factors are relevant to evaluating a stress-related mental disability claim. In
    this case, many of these nonoccupational factors are clearly present in the record, including
    plaintiff’s share of stressful life situations (a contentious divorce, estrangement from
    children, abandonment by a parent); use of alcohol; history of physical, sexual, and mental
    abuse; and few friends after moving to another state. Even accepting plaintiff’s testimony
    that she has been happily married for five years, common experience dictates that these
    factors do not simply dissipate, especially given that most of the factors are clearly
    ongoing. So, as the majority opinion emphasizes, consideration of the temporal proximity
    of mental injury to the work experience is relevant in this case, but it is not remotely
    dispositive given these ongoing stressors. Very few people simply “get over” the stress of
    a contentious divorce that results in a loss of custody and continued estrangement from
    their children and a parent. And since plaintiff relocated, she is no longer in regular contact
    with friends who might be able to help her cope with these ongoing factors. Under these
    circumstances, it is entirely appropriate that defendant would argue that plaintiff falsely or
    60
    Mayo Clinic, Mental Illness,  (accessed July 16, 2023).
    30
    mistakenly attributes all of her perceived problems to the February 8, 2012 workplace
    incident. And none of the majority’s other proposed factors, as set forth in Farrington 61—
    the physical stress to which the plaintiff was subjected, the conditions of employment, and
    the repeated return to work after each episode—are relevant.
    In sum, the majority’s new test is unnecessary, unhelpful, and should be rejected.
    C. THE UNDERLYING DECISION SHOULD BE AFFIRMED AND A REMAND IS
    UNECCESSARY
    The MCAC specified that “on February 8, 2012, plaintiff received an electrical
    shock arising out of and in the course of her employment with defendant which precipitated
    her fall from a ladder and injury to her right shoulder.” Reviewing courts must accept this
    factual conclusion if there is evidence in the record to support this finding. And more than
    ample evidence supports this finding. As mentioned, plaintiff was treated shortly after the
    February 8, 2012 incident at the Oakwood Annapolis Hospital, where she was assessed
    and, showing no indications of injury, released. Medical records contained a specific note
    that plaintiff denied any headaches, dizziness, or visual problems. The records did not
    reflect that she appeared confused or presented cognitive problems, nor was there any
    mention of a loss of consciousness.
    Other than plaintiff’s allegations, no evidence has been presented that plaintiff was
    injured at work from a fall hurting her head. Certainly, there is no evidence to support her
    claims that she was nearly electrocuted to death by a light fixture, was thrown off a ladder,
    first striking her head on a kitchen sink, and then somehow landed on the kitchen floor, not
    61
    Farrington, 
    442 Mich at 221
    .
    31
    only hurting her shoulder but also striking her head a second time. Clearly, had plaintiff
    arrived at the hospital after having suffered those injuries, there would be some indication
    of a head injury in the medical records. To the contrary, the hospital’s assessment and plan
    upon discharge stated, “after the whole assessment and work up, therefore it appears patient
    has escaped from any major injury or trauma to herself, will be going home most probably.”
    Plaintiff agreed with this document and later affirmed her agreement with the document
    during her trial testimony.
    Moreover, plaintiff’s own testimony at trial, if true, shows how her perception that
    she received a head injury may not have been grounded in reality. Plaintiff testified there
    were other people standing around, one saying, “[O]h my god, are you okay?” Another,
    plaintiff stated, “just stood there with her eyes as wide as wide could be.” Plaintiff stated
    that “[t]hey were the ones that told me what happened because I did lose consciousness at
    the time I got thrown. When I hit my head the second time I came to.” Plaintiff even
    claimed her supervisor told the two witnesses “to go and write up an accident report.”
    Plaintiff also testified that “Carol, who is one of the nurses, came in and took my blood
    pressure.” Plaintiff presented none of these witnesses. At the very least, plaintiff should
    have provided some evidence from her supervisor confirming the existence of the two
    witnesses to corroborate that she hit her head.
    Yet the majority opinion, contrary to our legislative directive on adopting the factual
    findings of the MCAC, inexplicably adopts plaintiff’s fanciful narrative of her workplace
    injury and ignores the circumstances surrounding plaintiff’s immediate treatment for the
    injury. Looking at the entire record, a clear theme emerges in that plaintiff repeatedly seeks
    treatment and emergency services for NESs that she unreasonably believes are related to
    32
    the February 8, 2012 workplace incident. No one, other than her current husband, has ever
    witnessed her alleged NESs, despite trained professionals in a clinical setting looking for
    any indication of NESs, including during a two-week period of continuous monitoring.
    Given plaintiff’s claim of experiencing NESs on a regular basis before the evaluation, one
    would expect at least one confirmed event during that period. Yet during the evaluation,
    plaintiff reported six seizures by pushing a button when she thought she was experiencing
    a seizure. All six of her claimed seizures were false. Her objective brain-wave testing did
    not show that she had experienced any indication of NESs during the evaluation, let alone
    any of the six times she claimed to suffer NESs.
    Basically, plaintiff has presented a marginal claim that would only support a
    conditional change from asymptomatic to symptomatic, which “does not equate with
    significant contribution.” 62 Likewise, “[j]ust because a claimant was functional before the
    workplace event and then becomes disabled after the event does not make the event
    significant.” 63
    A remand in this case is unnecessary for the same reasons that Yost declined to
    remand to the magistrate. In this case, plaintiff experts’ testimony “is even more generally
    flawed by the fact that [they] attributed importance to the workplace event in a strictly
    isolated theoretical setting [and they] assigned impact to the event at work based upon a
    faulty medical history.” 64 Like Yost, there is an “absence of any competent, material and
    62

    33
    substantial evidence on the whole record to support [a] finding of significant
    contribution . . . .” 65 Given the unlikelihood that plaintiff can establish her claim under the
    majority’s new test, I would not remand for further proceedings and, instead, would affirm
    the denial of plaintiff’s mental disability claim.
    IV. CONCLUSION
    The majority’s opinion unnecessarily and improperly disturbs Martin only to
    require additional factors be considered that are not very relevant to mental disability
    claims under MCL 418.301(2). I would affirm the Court of Appeals’ judgment affirming
    the MCAC’s decision, which, in turn, affirmed the magistrate’s denial of benefits for
    plaintiff’s alleged mental disability.
