    Before SYKES, Chief Judge, and HAMILTON and ST. EVE,
    Circuit Judges.
    ST. EVE, Circuit Judge. Larry Dunn slapped Andrew
    Schuckman in a bar’s parking lot, causing him to fall to the
    ground. Witnesses reported seeing Schuckman upright and
    apparently unharmed afterward, but hours later, he was
    found dead on the bar’s back patio. The state charged Dunn
    and his friend Michael Crochet with felony murder, battery,
    and theft from a corpse for stealing Schuckman’s cell phone.
    2                                                   No. 20-1168
    A key issue in the case was whether Dunn’s slap caused
    Schuckman’s death. In preparation for trial, Dunn’s counsel
    consulted with a forensic pathologist. After viewing the med-
    ical examiner’s report, the pathologist believed that Schuck-
    man died immediately from his head injuries—suggesting
    that Dunn’s slap could not have caused his death. In the
    months leading up to trial, defense counsel repeatedly—and
    erroneously—stated that he believed the medical examiner
    had concluded that Schuckman died immediately from a fatal
    blow to the back of his head and would testify to that at trial.
    Dunn’s counsel expressed this belief even though the medical
    examiner’s report did not contain these conclusions about the
    immediacy of death and he never confirmed them with her in
    advance of trial. Shortly before trial, the prosecutor informed
    Dunn’s counsel that Crochet, Dunn’s co-defendant, had dis-
    closed that he had retained experts for his case. These experts
    were going to produce reports containing information that
    bolstered Dunn’s no-causation defense; the prosecution con-
    sidered these reports to be exculpatory. Trial counsel did not
    ask for a continuance or attempt to view the reports’ contents,
    stating that the medical examiner would testify to the imme-
    diacy of death. At trial, defense counsel did not call his foren-
    sic pathologist as a witness. Furthermore, contrary to Dunn’s
    counsel’s expectations, the medical examiner testified that
    there was no reason to think that Schuckman would have died
    immediately from the fatal head injury, and it would have
    been possible for Schuckman to move after sustaining this in-
    jury.
    In state postconviction proceedings, Dunn asserted that
    his trial counsel had been ineffective for failing to investigate
    and present evidence that supported a no-causation defense
    to felony murder. The state appellate court concluded that
    No. 20-1168                                                     3
    Dunn’s trial counsel did not perform deficiently. Dunn then
    filed a habeas petition in federal court, which the district court
    granted. It reasoned that Dunn’s trial counsel provided inef-
    fective assistance by failing to investigate and offer evidence
    to support a no-causation defense. Federal courts “do not
    lightly grant petitions for a writ of habeas corpus brought by
    state prisoners,” and “if the ‘standard [for relief] is difficult to
    meet, that is because it was meant to be.’” Cook v. Foster, 
    948 F.3d 896
    , 899 (7th Cir. 2020) (quoting Harrington v. Richter, 
    562 U.S. 86
    , 102 (2011)). Here, we agree with the district court that
    Dunn has met this high bar—he is entitled to relief because he
    was prejudiced by his trial counsel’s deficient performance.
    We therefore affirm.
    I. Background
    A. Andrew Schuckman’s Death
    On May 9, 2011, Schuckman, Dunn, and Crochet were pa-
    trons of Peg & Lou’s Bar in Racine, Wisconsin. Dunn and Cro-
    chet were in town on business and they went to the bar with
    Crochet’s uncle, Fred Tennessen. Schuckman was intoxicated
    and had several unwelcome interactions in the bar with Cro-
    chet and other bar patrons. The bartender eventually asked
    Schuckman to leave and escorted him outside. Dunn and Cro-
    chet later encountered Schuckman in the bar’s parking lot.
    Dunn slapped Schuckman with his open left hand, which
    caused Schuckman to fall to the ground and hit his head.
    Dunn then went inside and told the bartender what had hap-
    pened and asked him to go check on Schuckman. When the
    bartender did not immediately do so, Dunn returned outside
    to check on Schuckman. After about ten to fifteen minutes, the
    bartender arrived and told Dunn to go back inside. The
    4                                                  No. 20-1168
    bartender escorted Schuckman to the bar’s back patio and left
    him on the grass next to a chair.
    Hours later, in the early morning of May 10, a bar patron
    discovered Schuckman’s body about five to six feet from
    where the bartender had left him. He was lying face up, and
    there was blood underneath his head and coming from his
    mouth and nose. His shirt was pulled up, and his pants were
    pulled down slightly. Several personal items, including his
    credit cards and wallet, lay near his body.
    B. Dunn’s Trial
    At trial, Dunn’s defense counsel advanced two key reasons
    why the jury should find Dunn not guilty—self-defense and
    a lack of causation. Dunn testified that he slapped Schuckman
    in self-defense because Schuckman approached him and Cro-
    chet with his fist raised. Trial counsel also argued that the
    state had failed to show that Dunn’s slap caused Schuckman’s
    death.
    The state put on several witnesses, including bar patrons,
    the bartender, an investigator, a DNA analyst, and the medi-
    cal examiner. The bartender testified that when he went out-
    side to check on Schuckman, he was sitting on the ground and
    had no physical marks on him. Schuckman seemed a little
    dazed, but mostly seemed intoxicated. He helped Schuckman
    stand up and then used his arms to help Schuckman walk to
    the back patio. A bar patron corroborated this testimony, tes-
    tifying that he saw the bartender talking to Schuckman in the
    parking lot and that Schuckman was breathing and seemed
    “fine as far as [the bar patron] could see.” The patron also saw
    the bartender help Schuckman stand up.
    No. 20-1168                                                    5
    Another bar patron testified that he saw Dunn, Crochet,
    and Tennessen leave the bar about ten to fifteen minutes be-
    fore him. When he exited the bar, Dunn was inside a pickup
    truck and another person—either Crochet or Tennessen—
    walked to the truck from the direction of the bar’s back patio.
    The medical examiner, Dr. Linda Biedryzycki, testified
    that Schuckman’s cause of death was blunt head injury. He
    had at least five different points of impact on his head, the
    most severe of which was a skull fracture and laceration to the
    back of his head. According to Dr. Biedryzycki, all Schuck-
    man’s head injuries contributed to his death. She testified that
    the injury to the back of the head was consistent with some-
    one striking the pavement or the ground. While she had no
    way of knowing definitively if the skull fracture caused in-
    stantaneous death, she opined that there was no reason to
    think it would because it did not affect his vital center. In her
    opinion, it was possible for someone to be able to move him-
    self after that type of injury. She also testified that Schuck-
    man’s blood alcohol level was .298%, which would affect his
    motor skills.
    A police investigator testified that a football-sized pool of
    blood lay under Schuckman’s head, and based on debris on
    Schuckman, it appeared as though he had been dragged by
    his legs. He further testified that investigators found pieces of
    Schuckman’s cell phone at the hotel where Crochet and Dunn
    were staying. The cell phone had been used after Schuckman
    died to call Dunn’s girlfriend. A DNA analyst also testified;
    he reported that Crochet’s pants had blood on them that
    matched Schuckman’s DNA, but there was no similar positive
    DNA match in the stains on Dunn’s clothing.
    6                                                         No. 20-1168
    Dunn testified in his own defense. He explained that
    Schuckman had been intoxicated and acted aggressively to-
    ward him and his friends in the bar. At some point, he went
    outside to get cigarettes; Crochet followed soon after to get
    medicine out of the truck. When Crochet went into the truck,
    Schuckman approached in an agitated manner with his fist
    balled up over his head. Dunn then slapped Schuckman with
    his open left hand. After notifying the bartender about what
    had happened and checking on Schuckman, Dunn went back
    inside the bar and did not see Schuckman for the rest of the
    night. When the men got back to the hotel, Dunn’s cell phone
    was dead. He grabbed what he thought was Crochet’s phone
    off the dresser and called his girlfriend to say goodnight.
    The jury found Dunn guilty of all three counts. The state
    court sentenced him to 10 years of imprisonment followed by
    8 years of extended supervision.
    C. Postconviction Proceedings
    Dunn filed a motion for postconviction relief in the state
    trial court, contending that his counsel was ineffective for fail-
    ing to investigate and present evidence of a no-causation de-
    fense.1 To succeed on this claim, under Strickland v. Washing-
    ton, 
    466 U.S. 668
     (1984), Dunn needed to show that his coun-
    sel’s performance was deficient and that he was prejudiced as
    a result. The court held an evidentiary hearing. Dunn called
    two witnesses: his trial counsel and a forensic pathologist, Dr.
    Peter Stephens. The state called the medical examiner who
    had testified at trial, Dr. Biedryzycki.
    1Dunn also argued he was entitled to relief on other grounds that are
    no longer at issue. Accordingly, we will not discuss them further.
    No. 20-1168                                                    7
    Dunn’s trial counsel testified that the cause of Schuck-
    man’s death was an important issue in the case. He had con-
    sulted with a forensic pathologist, Dr. Robert Corliss, twice
    before trial in order understand the medical examiner’s report
    on the cause of death. At the initial consultation, Dr. Corliss
    believed Schuckman had died immediately after receiving the
    head trauma based on the information in the medical exam-
    iner’s report. Dunn’s counsel erroneously believed that the
    medical examiner’s report stated this conclusion. He memori-
    alized this mistaken belief in two emails to the prosecutors,
    months apart, in which he stated that the medical examiner
    had concluded that Schuckman had died immediately from
    head trauma. He recognized, and pointed out to opposing
    counsel, that this fact undercut the state’s theory of the case.
    The bartender had witnessed Schuckman seemingly un-
    harmed after Dunn’s slap, suggesting it could not have been
    the cause of Schuckman’s death.
    In the month leading up to trial, Dunn’s counsel consulted
    with Dr. Corliss again. In that conversation, they focused on
    the fact that Schuckman sustained multiple head injuries, be-
    yond what would be explained by Dunn’s slap and Schuck-
    man’s fall. He planned to cross-examine the medical examiner
    on this point. At that time, Dunn’s counsel was still operating
    under the erroneous belief that the medical examiner was go-
    ing to testify that Schuckman’s death was immediate from the
    fatal blow to the back of his head. He expressed this belief just
    ten days before trial in response to an email from the prose-
    cutor. The prosecutor emailed him and stated that Crochet’s
    attorney had retained a blood spatter expert and a
    pathologist, who were going to produce reports purportedly
    establishing that Schuckman had stood up in the area where
    he was found and then fell and hit his head. Dunn’s trial
    8                                                  No. 20-1168
    counsel did not follow up with the prosecutor or contact Cro-
    chet’s attorney to inquire about reports’ contents. Rather, he
    wrote back to the prosecutor an hour later, stating that:
    Our theory of defense has always been that Mr. Dunn
    slapped Mr. Schuckman in self-defense; that he didn’t
    die immediately because people heard him talking,
    mumbling, grumbling after hitting the parking lot, and
    that the medical examiner will say he died immedi-
    ately. Therefore, there had to be a second time that his
    head hit the ground after Mr. Dunn’s slap that caused
    death. I believe that the testimony of the medical ex-
    aminer, combined with the testimony of [the bar-
    tender], supports that there has to be another hit irre-
    spective of what [Crochet’s attorney’s] pathologist
    says.
    Trial counsel did not speak with Dunn before sending this
    email, though he testified that Dunn had been clear about not
    wanting a continuance. He testified that he told Dunn about
    the prosecutor’s email sometime prior to trial.
    The expert reports referenced in the email were completed
    a week after Dunn’s trial concluded. There were three expert
    reports. First, a forensic pathologist wrote a report concluding
    that Schuckman suffered non-fatal injuries in the parking lot
    and he died due to injuries he received after falling backwards
    on the bar’s back patio. Second, a blood analyst concluded
    that Schuckman was not bleeding in the parking lot and he
    was never upright after sustaining the injury to the back of his
    head. Third, a neurologist and mechanical engineer calcu-
    lated that Schuckman could have generated enough velocity
    No. 20-1168                                                          9
    falling backwards on the back patio to fracture his skull, and
    extreme intoxication can result in such an “unbroken” fall.2
    Trial counsel stated that by the time Dunn’s trial started,
    he understood that the medical examiner would not testify
    that death was immediate. Given his email to the prosecutor,
    this understanding must have occurred sometime in the ten
    days before trial. Dunn’s counsel testified that he had no re-
    gret over not calling Dr. Corliss as a witness; he planned to
    draw out the fact that there were multiple injuries when cross-
    examining the medical examiner. He believed eliciting that
    testimony from a state’s witness was more advantageous for
    his client than calling his own witness. He further testified
    that Dr. Corliss told him that the medical examiner’s conclu-
    sions in the autopsy report were well-reasoned.
    During the postconviction hearing, Dunn also presented
    the testimony of Dr. Stephens, a forensic pathologist. Dr. Ste-
    phens opined that the laceration and skull fracture in the back
    of Schuckman’s head were the substantial cause of his death
    because he likely would have survived the other head inju-
    ries. He further opined that Schuckman sustained the skull
    fracture on the bar’s back patio—not the parking lot where
    Dunn had slapped him. In reaching this conclusion, he relied
    on the nature of the injury and the lack of blood in the parking
    lot and on Schuckman’s shirt. He testified that the nature of
    the impact causing the skull fracture would cause an immedi-
    ate loss of consciousness, Schuckman would have been un-
    likely to be able to sit up and talk afterward, and he would
    2  The state later dismissed Crochet’s felony murder charge and al-
    lowed him to plead guilty to aiding a felon and misdemeanor battery. He
    received a sentence of time served.
    10                                                No. 20-1168
    have died within a matter of minutes. Additionally, the
    amount of blood found underneath Schuckman’s head and
    the lack of blood in the parking lot supported his conclusion
    that Schuckman received the skull fracture and laceration on
    the back patio. If Schuckman had lived longer than a few
    minutes, the pool of blood would have been bigger. Further,
    the laceration’s size on the back of Schuckman’s head indi-
    cates it had the potential to bleed significantly and profusely
    because the scalp is highly vascular. The wound would have
    bled immediately. So if Schuckman had sustained it in the
    parking lot, one would expect to find blood both there and on
    Schuckman’s shirt because the bartender and bar patron saw
    Schuckman upright in the parking lot several minutes after
    Dunn slapped him. Thus, Dr. Stephens opined that Schuck-
    man was never upright after sustaining the laceration and
    skull fracture, and so these injuries must have occurred on the
    back patio.
    Dr. Biedryzycki testified for the state at the hearing. She
    opined that the laceration was relatively small and not gap-
    ing, so it may or may not have bled a lot. The nature of
    Schuckman’s head injury did not lead her to assume that
    blood had to be present immediately after being injured. Fur-
    ther, she opined that the amount of blood under Schuckman’s
    head could not be used to determine how long he lived after
    receiving the injuries because blood could have continued to
    pool around his head even after death due to hydrostatic pres-
    sure. She acknowledged that there was nothing in her autopsy
    report that was inconsistent with Schuckman sustaining the
    skull fracture and laceration on the back patio.
    The trial court held that Dunn’s ineffective assistance of
    counsel claim failed Strickland’s prejudice prong. The
    No. 20-1168                                                  11
    Wisconsin Court of Appeals affirmed the denial of Dunn’s
    postconviction motion. State v. Dunn, 
    372 Wis. 2d 458
     (Wis. Ct.
    App. 2016) (per curiam). It “was not persuaded that trial
    counsel performed deficiently in his investigation of
    Schuckman’s death and presentation of a no-causation
    defense.” Id. ¶ 13. The state appellate court noted that Dunn’s
    trial counsel consulted with a forensic pathologist. Id. It
    further determined that “trial counsel’s testimony provides a
    reasonable explanation for his approach,” because he had
    strategic and practical reasons for not calling Dr. Corliss as a
    witness. Id. ¶¶ 15–16. Strategically, he believed he could get
    the medical examiner to testify about the presence of multiple
    injuries on cross-examination, and practically, Dr. Corliss told
    counsel that he thought the medical examiner’s report was
    well-reasoned. Id. ¶ 16. The state appellate court concluded
    that “[w]hile another lawyer may have handled the matter
    differently, that is not the standard for judging whether
    counsel’s representation was incompetent.” Id. The Wisconsin
    Court of Appeals did not reach Strickland’s prejudice prong.
    Dunn then filed a petition for a writ of habeas corpus un-
    der 
    28 U.S.C. § 2254
     in the United States District Court for the
    Eastern District of Wisconsin. The district court granted
    Dunn’s habeas petition, concluding that he had received inef-
    fective assistance of counsel. Dunn v. Jess, 
    430 F. Supp. 3d 568
    (E.D. Wis. 2019). It reasoned that Dunn’s counsel’s investiga-
    tion of Schuckman’s death and of a no-cause defense was in-
    sufficient under any reasonable application of Strickland, be-
    cause he failed to interview the medical examiner before trial,
    call a forensic pathologist, or investigate the exculpatory re-
    ports. Thus, the district court concluded that the state appel-
    late court unreasonably applied Strickland’s performance
    prong.
    12                                                 No. 20-1168
    Because the state appellate court did not address
    Strickland’s prejudice prong, the district court reviewed the
    prong de novo. The court concluded that “Dunn has
    demonstrated a reasonable probability that the result would
    have been different had Dunn’s counsel adequately presented
    the no-causation defense and the jury heard expert testimony
    of the sort presented by Dr. Stephens.” Id. at 579. Because Dr.
    Stephens’s testimony “substantially undermines one’s
    confidence in the result” of the trial, while “the jury may have
    reached the same conclusion even with such evidence,” Dunn
    had provided sufficient evidence “to establish prejudice
    under Strickland.” Id. at 580. The district court thus granted
    Dunn’s habeas petition, and the state now asks us to reverse.
    II. Discussion
    “Under the Antiterrorism and Effective Death Penalty Act
    of 1996 (AEDPA), a federal court is not authorized to issue a
    writ of habeas corpus on a claim rejected by a state court on
    the merits unless the state-court decision ‘was contrary to, or
    involved an unreasonable application of, clearly established
    Federal law, as determined by the Supreme Court’ or ‘was
    based on an unreasonable determination of the facts.’” Cook,
    948 F.3d at 901 (quoting 
    28 U.S.C. § 2254
    (d)). A state-court de-
    cision “unreasonably applies federal law if it correctly identi-
    fies the governing Supreme Court precedent but unreasona-
    bly applies its holding to the facts of the case.” 
    Id.
    This standard “sets a high bar for state prisoners seeking
    federal habeas review.” Jones v. Calloway, 
    842 F.3d 454
    , 460
    (7th Cir. 2016). When a state court has reached an issue on the
    merits, the inquiry is not whether we “agree with the state
    court decision or even whether the state court decision was
    correct,” it is “whether the decision was unreasonably wrong
    No. 20-1168                                                   13
    under an objective standard.” Dassey v. Dittmann, 
    877 F.3d 297
    , 302 (7th Cir. 2017) (en banc). If the standard “is difficult
    to meet, that is because it was meant to be.” Richter, 
    562 U.S. at 102
    . “Nonetheless, ‘difficult’ does not mean ‘impossible’ …
    ‘[t]he writ of habeas corpus stands as a safeguard against im-
    prisonment of those held in violation of the law.’” Cook, 948
    F.3d at 899 (quoting Richter, 
    562 U.S. at 91
    ).
    Strickland provides the clearly established federal law for
    Dunn’s ineffective assistance of counsel claim. “A petitioner
    raising a Strickland claim is required to demonstrate two
    things.” Winfield v. Dorethy, 
    956 F.3d 442
    , 451 (7th Cir. 2020).
    “First, he must show that counsel provided constitutionally
    deficient performance” and second, he must “show that this
    deficient performance prejudiced his defense.” 
    Id.
     at 451–52.
    “Failing to prove either element defeats a petitioner’s claim.”
    Id. at 452.
    AEDPA deference only applies to issues that the last rea-
    soned state court decision reached on the merits. Here, the
    Wisconsin Court of Appeals reached the question of whether
    Dunn satisfied Strickland’s performance prong. When the
    state court “‘explains its decision on the merits in a reasoned
    opinion,’ this presents a ‘straightforward inquiry’ for the fed-
    eral habeas court.” Lentz v. Kennedy, 
    967 F.3d 675
    , 688 (7th Cir.
    2020) (quoting Wilson v. Sellers, 
    138 S. Ct. 1188
    , 1192 (2018)).
    “[W]e focus on that decision and ‘simply review[] the specific
    reasons given by the state court and defer[] to those reasons if
    they are reasonable.’” 
    Id.
     (quoting Wilson, 
    138 S. Ct. at 1192
    ).
    Habeas relief is only warranted here if Dunn shows that the
    state appellate court’s determination that his counsel did not
    perform deficiently “was so lacking in justification that there
    was an error well understood and comprehended in existing
    14                                                    No. 20-1168
    law beyond any possibility for fairminded disagreement.”
    Richter, 
    562 U.S. at 103
    . The Wisconsin Court of Appeals did
    not reach Strickland’s prejudice prong, and so the parties agree
    that AEDPA deference does not apply and we review that
    prong de novo.
    A. Deficient Performance
    “To establish deficient performance, a person challenging
    a conviction must show that ‘counsel’s representation fell be-
    low an objective standard of reasonableness.’” Richter, 
    562 U.S. at 104
     (quoting Strickland, 
    466 U.S. at 688
    ). This means a
    petitioner must identify errors “so serious that counsel was
    not functioning as the ‘counsel’ guaranteed the defendant by
    the Sixth Amendment.” 
    Id.
     (quoting Strickland, 
    466 U.S. at 687
    ). “To avoid the inevitable temptation to evaluate a law-
    yer’s performance through the distorting lens of hindsight,
    Strickland establishes a deferential presumption that strategic
    judgments made by defense counsel are reasonable.” Mosley
    v. Atchison, 
    689 F.3d 838
    , 848 (7th Cir. 2012). But for this defer-
    ence to apply, the decision must be—in fact—strategic. “The
    consequences of inattention rather than reasoned strategic de-
    cisions are not entitled to the presumption of reasonableness.”
    
    Id.
     (citing Rompilla v. Beard, 
    545 U.S. 374
    , 395–96 (2005)). We
    “judge the reasonableness of counsel’s challenged conduct on
    the facts of the particular case, viewed as of the time of coun-
    sel’s conduct.” Strickland, 
    466 U.S. at 690
    . Our review of the
    state court’s decision is “‘doubly deferential,’ … [and] gives
    both the state court and the defense attorney the benefit of the
    doubt.” Burt v. Titles, 
    571 U.S. 12
    , 15 (2013) (quoting Cullen v.
    Pinholster, 
    563 U.S. 170
    , 190 (2011)).
    The Wisconsin Court of Appeals concluded that Dunn’s
    trial counsel did not perform deficiently in failing to
    No. 20-1168                                                    15
    investigate and present a no-causation defense because he (1)
    consulted with a pathologist and (2) provided strategic and
    practical explanations for his approach. Upon closely
    examining the facts of this case, we find that the Wisconsin
    Court of Appeals unreasonably applied Strickland because
    Dunn’s counsel was poorly informed and based his strategic
    decisions on a complete misunderstanding of a key piece of
    evidence—namely, the medical examiner’s opinion on the
    immediacy of death.
    It was unreasonable for the state appellate court to find
    that trial counsel did not perform deficiently because he con-
    sulted with a forensic pathologist. Indeed, at the initial con-
    sultation, Dr. Corliss provided trial counsel with a crucial
    piece of evidence supporting Dunn’s no-causation defense: he
    thought Schuckman died immediately. Whether Dunn
    caused Schuckman’s death was a critical issue in the case. The
    state’s main theory of the case depended on connecting two
    events: Dunn slapping Schuckman in the bar’s parking lot,
    and Schuckman being found dead hours later on the bar’s
    back patio. Evidence that Schuckman would have died imme-
    diately after receiving his fatal head injuries would have lent
    strong support that these two events were not causally con-
    nected because multiple witnesses saw Schuckman alive, ap-
    parently unharmed, and upright after Dunn slapped him. Yet
    Dunn’s counsel seemingly misattributed Dr. Corliss’s opinion
    that death was immediate to the medical examiner, and erro-
    neously believed that the medical examiner’s report meant
    she would testify to that at trial. He failed to confirm that the
    medical examiner would introduce this key piece of evidence
    at trial or otherwise investigate the immediacy of death. His
    mistaken belief infected his trial strategy to such an extent that
    his approach to investigating and presenting a no-causation
    16                                                   No. 20-1168
    defense cannot be reasonably viewed as strategic, even with
    the “heavy measure of deference” afforded him under Strick-
    land. 
    466 U.S. at 691
    . His “failure to investigate thoroughly re-
    sulted from inattention, not reasoned strategic judgment.”
    Wiggins v. Smith, 
    539 U.S. 510
    , 526 (2003). It is thus unreason-
    able to view trial counsel’s decision to consult with a forensic
    pathologist as satisfactory performance, considering trial
    counsel did not use the crucial information gleaned from that
    consultation.
    It was also unreasonable for the state appellate court to
    find that trial counsel’s explanation for his approach con-
    tained reasonable strategic and practical reasons. Dunn’s
    counsel explained he did not call Dr. Corliss as a witness be-
    cause he thought the evidence would be more persuasive if
    elicited from the medical examiner on cross-examination. The
    state appellate court found this explanation demonstrated
    that trial counsel was acting strategically. This overlooks the
    fact that trial counsel was not able to elicit a crucial piece of
    evidence from the medical examiner on cross-examination:
    that Schuckman died immediately. “A court adjudicating a
    Strickland claim can’t just label a decision ‘strategic’ and
    thereby immunize it from constitutional scrutiny,” and the
    state court’s determination that trial counsel was acting stra-
    tegically here is not reasonable. Jones, 842 F.3d at 464. In fact,
    his causation strategy was primarily based on the improbable
    assumption that the state’s medical examiner would testify
    that the state’s causation theory was medically impossible.
    And when that unlikely strategy blew up, counsel had no
    Plan B.
    Trial counsel and the state appellate court seemingly view
    the evidence about multiple injuries—which trial counsel was
    No. 20-1168                                                   17
    able to elicit on cross-examination—as substitute evidence in
    support of a no-causation defense. But while evidence that
    Schuckman had more injuries than could be explained by the
    slap and fall lends some support to the theory that Dunn did
    not cause his death, it is not nearly as strong as evidence that
    Schuckman died immediately after the blunt force trauma to
    the back of his head. The medical examiner testified that all
    Schuckman’s injuries contributed to his death. In order to
    convict for felony murder, the jury only needed to find that
    Dunn’s conduct was a substantial factor in bringing about
    Schuckman’s death. See State v. Oimen, 
    184 Wis. 2d 423
    , 404–
    05 (1994). So while the presence of multiple injuries suggests
    that Schuckman may also have been injured by someone or
    something other than Dunn, given the medical examiner’s tes-
    timony that all the injuries contributed to his death, the jury
    could still reasonably find that the Dunn’s slap was a substan-
    tial factor in his death. Evidence that Schuckman died imme-
    diately from one fatal blow, conversely, is much stronger evi-
    dence that Dunn did not cause his death. Multiple witnesses
    saw Schuckman alive, apparently unharmed, and standing
    several minutes after Dunn slapped him. Given this, trial
    counsel’s explanation for not calling his forensic
    pathologist—that he could elicit the relevant information
    from the medical examiner on cross-examination—cannot be
    reasonably viewed as strategic. See Washington v. Smith, 
    219 F.3d 620
    , 630–34 (7th Cir. 2000) (finding ineffective assistance
    where counsel failed to investigate and call additional alibi
    witnesses because the defendant’s location “was the issue in
    the case,” and the one alibi witness counsel called had ques-
    tionable credibility because he had a prior conviction).
    Trial counsel’s “practical” explanation for why he did not
    call Dr. Corliss as a witness also fails. Trial counsel testified
    18                                                  No. 20-1168
    that he did not call Dr. Corliss because the pathologist told
    him the medical examiner’s conclusions in the report were
    well-reasoned. But the medical examiner’s conclusion that
    there was an interval of survival was not contained in her re-
    port. And when trial counsel spoke with Dr. Corliss in April,
    trial counsel still had the mistaken belief—memorialized by
    his email a mere ten days before trial—that the medical exam-
    iner would testify that death was immediate. So while it fol-
    lows that at the time trial counsel spoke with Dr. Corliss there
    was no contradiction between Dr. Corliss’s opinion and the
    medical examiner’s perceived opinion, when trial counsel re-
    alized that the medical examiner disagreed on the immediacy
    of death, his decision to not call his pathologist cannot reason-
    ably be called “practical.” For these reasons, the state appel-
    late court unreasonably applied Strickland when it deter-
    mined that counsel did not perform deficiently because he
    had strategic and practical reasons for his approach to Dunn’s
    no-causation defense.
    None of the state appellate court’s stated reasons for find-
    ing trial counsel’s performance satisfactory are reasonable.
    Further, the Wisconsin Court of Appeals failed to adequately
    consider or address counsel’s decision to disregard the excul-
    patory expert reports he was informed about shortly before
    trial. Dunn’s counsel did not seek out further information on
    the reports or ask for a continuance. While “reasonably dili-
    gent counsel may draw a line when they have good reason to
    think further investigation would be a waste,” Rompilla, 
    545 U.S. at 383
     (emphasis added), here trial counsel only had a
    bad reason not to follow up: his inaccurate belief that he al-
    ready had a witness who would provide similar testimony. A
    No. 20-1168                                                              19
    tactical decision based on a complete misunderstanding of an
    essential piece of evidence does not equate to strategy.3
    Sometime in the days before trial, trial counsel figured out
    that the medical examiner would not testify as he thought she
    would. Thus, “[e]ven if defense counsel could have initially
    believed expert testimony unnecessary,” finding out the med-
    ical examiner was going to testify that Schuckman did not die
    immediately should “have alerted any reasonable attorney to
    the need to rebut with a defense expert.” Woolley v. Rednour,
    
    702 F.3d 411
    , 423 (7th Cir. 2012) (finding counsel performed
    deficiently where he “remained nearly passive in the face of
    damning” testimony that “effectively hollowed out the core
    of his client’s defense” because he “fail[ed] to retain an expert
    witness” or “ask for a continuance”). Given that he knew that
    he no longer could elicit this crucial piece of information on
    cross-examination, his planned approach to the no-causation
    defense at trial cannot reasonably be viewed as strategic. Ra-
    ther than calling Dr. Corliss to testify or requesting a continu-
    ance to obtain the exculpatory reports, he decided to rely on
    his cross-examination of the medical examiner to advance the
    no-causation defense. But the information he could elicit from
    her—that Schuckman sustained multiple injuries—only pro-
    vided weak support that Dunn’s slap was not a substantial
    factor in Schuckman’s death. He failed to offer any evidence
    to rebut the medical examiner’s conclusions that there was an
    3 Trial counsel’s testimony that Dunn would not have wanted a con-
    tinuance to wait for the completed expert reports does not render his de-
    cision to not investigate further strategic. Counsel had a fundamental mis-
    understanding about how a key witness would testify, which prevented
    him from being able to accurately advise his client on the state of the evi-
    dence and the potential necessity of a continuance.
    20                                                 No. 20-1168
    interval of survival and all Schuckman’s injuries contributed
    to his death. He did not present any evidence whatsoever that
    Schuckman died immediately—despite having both a foren-
    sic pathologist who had expressed this belief and the infor-
    mation about exculpatory expert reports that suggested that
    Schuckman died on the back patio and did not stand upright
    after the fatal injury.
    Trial counsel’s approach to presenting a no-causation de-
    fense was thus, “in light of all the circumstances … outside
    the wide range of professionally competent assistance.”
    Strickland, 
    466 U.S. at 690
    . This finding does not mean that
    counsel must always interview a medical examiner or retain
    an expert witness to be considered effective. “[I]t may be rea-
    sonable,” in some cases, “to rely on cross-examination to cast
    general doubt on the government’s version of events.” Wool-
    ley, 702 F.3d at 424. It also may be reasonable to rely on the
    medical examiner’s report, or to not seek out additional excul-
    patory information if it were cumulative. But here, trial coun-
    sel’s investigation and presentation of a no-causation defense
    rested on an erroneous belief, until days before trial, that he
    would be able to elicit a crucial piece of information from the
    medical examiner. He then remained “nearly passive in the
    face of damning” testimony from the medical examiner that
    Dunn caused Schuckman’s death. Woolley, 702 F.3d at 423. We
    thus conclude that Dunn’s trial counsel’s performance was
    deficient under Strickland.
    B. Prejudice
    We next turn to Strickland’s prejudice prong, which we re-
    view de novo in light of the state appellate court’s silence on
    this point. To prevail, Dunn must “affirmatively prove preju-
    dice,” meaning that “there is a reasonable probability that, but
    No. 20-1168                                                 21
    for counsel’s unprofessional errors, the result of the proceed-
    ing would have been different.” Strickland, 
    466 U.S. at
    693–94.
    “A reasonable probability is a probability sufficient to under-
    mine confidence in the outcome.” 
    Id. at 694
    . This does not re-
    quire Dunn to prove that his “counsel’s deficient conduct
    more likely than not altered the outcome in the case,” 
    id. at 693
    , but the “likelihood of a different result must be substan-
    tial, not just conceivable.” Richter, 
    562 U.S. at 112
    .
    We conclude that there is a reasonable probability that the
    result would have been different if Dunn’s trial counsel had
    adequately investigated and presented evidence that Dunn
    did not cause Schuckman’s death. Given the evidence that
    Schuckman was seen alive and apparently unharmed after
    the slap meant that the medical examiner’s testimony at trial
    was key in linking Dunn’s slap to Schuckman’s death. Her
    testimony that all Schuckman’s injuries contributed to his
    death and there was no reason to think he died quickly went
    unrebutted at trial. Dr. Stephens’s testimony cast significant
    doubt on these conclusions and is sufficient to undermine our
    confidence in the outcome. See Mosley, 689 F.3d at 851 (hold-
    ing that where important testimony was not offered and the
    evidence against the defendant was not overwhelming, Strick-
    land’s prejudice prong was satisfied).
    Dr. Stephens’s testimony contradicted the medical exam-
    iner’s in two key ways. First, while the medical examiner tes-
    tified that all Schuckman’s injuries contributed to his death,
    Dr. Stephens opined the skull fracture and laceration to the
    back of Schuckman’s head were the substantial cause of his
    death and he likely would have survived his other injuries.
    Second, Dr. Stephens disagreed with the medical examiner
    about how long Schuckman likely survived after sustaining
    22                                                  No. 20-1168
    the skull fracture. The medical examiner testified she had no
    reason to think that Schuckman would have died immedi-
    ately from his injuries because they did not affect his vital cen-
    ter; Dr. Stephens testified that Schuckman would have been
    rendered immediately unconscious, would be unlikely to be
    able to sit up afterward, and would have died within minutes.
    An analogous set of facts arose in Rogers v. Israel, 
    746 F.2d 1288
    , 1293–94 (7th Cir. 1984). There, like here, a crucial ques-
    tion in the case was whether the victim in a bar fight was im-
    mediately incapacitated by his injuries. Trial counsel in both
    cases failed to rebut the state’s pathologist’s testimony that
    incapacitation would not occur immediately, though the
    counsel could have presented such expert testimony. In Rog-
    ers, we found that expert testimony regarding the immediacy
    of incapacitation “was critical to the presentation of the de-
    fense,” and so there was a reasonable probability that the jury
    would have had a reasonable doubt about the defendant’s
    guilt if it had been presented. 
    Id. at 1293
    . We find the same
    here.
    In addition to rebutting some of the medical examiner’s
    testimony, Dr. Stephens’s testimony undermined the state’s
    theory of the case in other ways. He testified that the lacera-
    tion on the back of Schuckman’s head would bleed immedi-
    ately and profusely. Yet there was no blood found in the park-
    ing lot, and Schuckman did not have blood dripping down
    the back of his head. Dr. Stephens’s opinion based on these
    facts—that Schuckman was injured on the back patio rather
    than in the parking lot—thus contradicted the state’s theory
    of the case. The medical examiner conceded at the postconvic-
    tion hearing that nothing in her testimony was inconsistent
    with Schuckman receiving his injuries on the back patio.
    No. 20-1168                                                  23
    We recognize that the medical examiner’s testimony was
    not the only incriminating evidence in this case. Even at a hy-
    pothetical trial where counsel presented testimony like that of
    Dr. Stephens’s, the jury would have learned that Schuckman’s
    cell phone was found at Dunn and Crochet’s hotel, Schuck-
    man’s DNA was found on Crochet’s pants, and Crochet was
    spotted walking from the direction where Schuckman was
    found later that night. “Logically, a verdict weakly supported
    by the record is more likely to have been affected by errors
    than one with overwhelming record support.” Cook, 948 F.3d
    at 909. But we do not find this other evidence constitutes over-
    whelming support that Dunn is guilty of felony murder. Ra-
    ther, much of this evidence potentially incriminates Crochet.
    It was Crochet who had Schuckman’s blood on his pants, and
    Crochet who was witnessed leaving the bar, and ten to fifteen
    minutes later, walking away from the direction where
    Schuckman was later found. But Dunn’s guilt is not neces-
    sarily tied with Crochet’s—the same witness who testified he
    saw Crochet walking away from the area where Schuckman
    was found also testified that he saw Dunn seated in the
    pickup truck at that time. And notably, despite the forensic
    and eyewitness testimony implicating Crochet in Schuck-
    man’s death, Crochet was able to leverage the exculpatory ex-
    pert reports to negotiate a plea bargain for a time-served sen-
    tence.
    There is of course a chance that even if the jury had heard
    testimony like that offered by Dr. Stephens, it would have
    nonetheless convicted Dunn for felony murder. It may have
    still found that Dunn’s slap caused the skull fracture, or that
    Dunn was liable as a party to a crime based on the evidence
    against Crochet. But the fact that no evidence was offered
    about the timing and location of Schuckman’s death
    24                                                 No. 20-1168
    substantially undermines our confidence in this result. This is
    sufficient to establish prejudice under Strickland.
    III. Conclusion
    The Wisconsin Court of Appeals unreasonably applied
    Strickland when it determined that Dunn’s trial counsel did
    not perform deficiently. Dunn was prejudiced as a result of
    his trial counsel’s errors, and so the district court’s grant of
    habeas relief is
    AFFIRMED.
