    OPINION OF THE COURT
    __________
    ALDISERT, Circuit Judge.
    David W. Covell and Margaret Covell, who are plenary
    guardians of their adult son David F. Covell, appeal from a
    jury’s verdict for the defendant in their products liability suit
    against Easton-Bell Sports, Inc. They urge us to order a new
    trial on the ground that the District Court erred by admitting
    evidence and charging the jury pursuant to sections 1 and 2 of
    the Restatement (Third) of Torts (1998), rather than section
    402A of the Restatement (Second) of Torts (1965). Having
    3
    held in Berrier v. Simplicity Manufacturing, Inc., 
    563 F.3d 38
    (3d Cir. 2009), cert. denied, 
    130 S. Ct. 553
     (2009), that federal
    district courts applying Pennsylvania law to products liability
    cases should look to sections 1 and 2 of the Restatement
    (Third) of Torts, and seeing no reason to reverse course now,
    we will affirm.
    I.
    David F. Covell, a 36 year-old schoolteacher, sustained
    serious brain injuries when he was struck by a car while
    bicycling to work in 2007. Tragically, he is now so disabled
    that his parents (the “Covells”) have been appointed his legal
    guardians. In that capacity, they filed this products liability suit
    against Easton-Bell Sports, Inc. (“Bell”), which manufactured
    the “Giro Monza” bicycle helmet their son wore during the
    collision. Their suit, filed in the Pennsylvania Court of
    Common Pleas, alleged that the Giro Monza helmet was
    defectively designed and that it lacked adequate warnings
    about danger from impact to the helmet’s edge. Bell removed
    the case to the United States District Court for the Eastern
    District of Pennsylvania, where the trial proceeded according
    to Pennsylvania substantive law.
    At trial, and over the Covells’ strident objections, the
    District Court permitted Bell to introduce expert testimony that
    was based in part upon the United States Consumer Product
    Safety Commission’s Safety Standard for Bicycle Helmets
    (the “CPSC Standard”). The CPSC Standard is an
    administrative regulation that provides an exacting set of
    guidelines for impact resistance, head covering, labels on
    helmets and helmet boxes, helmet resistance to temperature
    and moisture, manufacturer recordkeeping, and much more.
    4
    See 
    16 C.F.R. § 1203
    . Forced to respond to Bell’s expert, the
    Covells offered their own expert testimony regarding the
    CPSC Standard. Ultimately, experts for both sides agreed that
    the CPSC Standard forms the starting point for any bicycle
    helmet design, and that the Giro Monza helmet satisfied the
    CPSC Standard in all respects.
    At the trial’s conclusion, the District Court instructed
    the jury pursuant to sections 1 and 2 of the Restatement (Third)
    of Torts. The Court also instructed the jury that, in determining
    whether the Giro Monza helmet was or was not defective, it
    could consider evidence of standards or customs in the bicycle
    helmet industry, including the CPSC Standard. The jury
    returned a verdict for the defense, finding that the helmet was
    not defective. The Covells timely filed this appeal.
    II.
    The District Court had diversity jurisdiction pursuant to
    
    28 U.S.C. § 1332
    (a)(1). We have jurisdiction pursuant to 
    28 U.S.C. § 1291
    .
    We review issues of law de novo. Bear Mt. Orchards,
    Inc. v. Mich-Kim, Inc., 
    623 F.3d 163
    , 169 (3d Cir. 2010). This
    includes a District Court’s decision to admit or exclude
    evidence pursuant to Pennsylvania law. Dillinger v.
    Caterpillar, Inc., 
    959 F.2d 430
    , 434-435 (3d Cir. 1992).
    III.
    The Covells call to our attention two assignments of
    error. First, they contend that the District Court should not
    have applied the Restatement (Third) of Torts when instructing
    5
    the jury and when admitting evidence of the CPSC Standard.
    Second, they contend that even if it was proper to apply the
    Restatement (Third) of Torts, the CPSC Standard was
    nonetheless inadmissible. We disagree and will affirm the
    District Court on both counts.
    A.
    We begin with the District Court’s decisions to admit
    evidence and to instruct the jury pursuant to the Restatement
    (Third) and not the Restatement (Second) of Torts. We note at
    the outset that the question the Covells present—what is the
    law of Pennsylvania: section 402A of the Restatement
    (Second) of Torts, or sections 1 and 2 of the Restatement
    (Third) of Torts?—is one we laid to rest only 24 months ago in
    Berrier v. Simplicity Manufacturing, Inc., 
    563 F.3d 38
    , 40 (3d
    Cir. 2009) (holding that if confronted with the question, the
    Supreme Court of Pennsylvania would apply sections 1 and 2
    of the Restatement (Third) of Torts to products liability cases),
    cert. denied, 
    130 S. Ct. 553
     (2009). After examining the
    contentions of the parties and the recent decisions of
    Pennsylvania’s highest court, we conclude that the state of the
    law is no different now than it was when we decided Berrier.
    Rather than exhume the arguments and considerations we laid
    to rest there, we will apply stare decisis.
    1.
    In past products liability cases, the Supreme Court of
    Pennsylvania has looked to section 402A of the Restatement
    (Second) of Torts. E.g., Webb v. Zern, 
    220 A.2d 853
    , 854 (Pa.
    1966) (“We hereby adopt the foregoing language [of § 402A]
    as the law of Pennsylvania.”). Section 402A makes sellers
    6
    liable for harm caused to consumers by unreasonably
    dangerous products, even if the seller exercised reasonable
    care:
    (1) One who sells any product in a defective
    condition unreasonably dangerous to the user
    or consumer or to his property is subject to
    liability for physical harm thereby caused to
    the ultimate user or consumer, or to his
    property, if
    (a) the seller is engaged in the business of
    selling such a product, and
    (b) it is expected to and does reach the user or
    consumer without substantial change in
    the condition in which it is sold.
    (2) The rule stated in Subsection (1) applies
    although
    (a) the seller has exercised all possible care
    in the preparation and sale of his product,
    and
    (b) the user or consumer has not bought the
    product from or entered into any
    contractual relation with the seller.
    Restatement (Second) of Torts § 402A (1965). Section 402A
    thus creates a strict liability regime by insulating products
    liability cases from negligence concepts. See id. § 402A(2)(a);
    Azzarello v. Black Bros. Co., 
    391 A.2d 1020
    , 1025-1026 (Pa.
    7
    1978) (charging courts to avoid negligence concepts when
    instructing a jury pursuant to § 402A.).
    During the past 40 years, however, the Supreme Court
    of Pennsylvania has repeatedly addressed confusion arising
    from a core conflict in the structure of section 402A itself:
    Section 402A instructs courts to ignore evidence that the seller
    “exercised all possible care in the preparation and sale of his
    product,” § 402A(2)(a), yet imposes liability only for products
    that are “unreasonably dangerous,” § 402A(1). In many cases
    it is difficult or impossible to determine whether a product is
    “unreasonably dangerous” to consumers without reference to
    evidence that the seller did or did not exercise “care in the
    preparation” of the product. See Schmidt v. Boardman Co., 
    11 A.3d 924
    ,       940        (Pa.       2011)       (“This
    no-negligence-in-strict-liability rubric has resulted in material
    ambiguities and inconsistency in Pennsylvania’s procedure.”);
    see also Phillips v. Cricket Lighters, 
    841 A.2d 1000
    ,
    1015-1016 (Pa. 2003) (Saylor, J., dissenting).
    Nonetheless, the Supreme Court of Pennsylvania has
    endeavored to segregate strict liability’s “product-oriented”
    analysis from the “conduct-oriented” analysis of negligence.
    Phillips, 841 A.2d at 1006 (“[W]e have remained steadfast in
    our proclamations that negligence concepts should not be
    imported into strict liability law . . .”). In so doing,
    Pennsylvania’s high court has stated repeatedly that
    negligence concepts have no place in products liability. E.g.,
    id.; Azzarello, 
    391 A.2d at 1025-1026
    . That endeavor has not
    always been successful, see Davis v. Berwind Corp., 
    690 A.2d 186
    , 190 (Pa. 1997) (holding that if a “product has reached the
    user or consumer with substantial change,” liability depends
    upon “whether the manufacturer could have reasonably
    8
    expected or foreseen such an alteration of its product.”)
    (emphasis added), nor has it been uniformly embraced by the
    Justices of that Court, see Schmidt, 11 A.3d at 940
    (disapproving of Pennsylvania’s “almost unfathomable
    approach to products litigation”) (quotation omitted).
    The American Law Institute responded to the core
    conflict in section 402A when it published the Restatement
    (Third) of Torts. Sections 1 and 2 of the Restatement (Third) of
    Torts abandon entirely the negligence-versus-strict-liability
    distinction that has caused so much trouble in Pennsylvania:
    § 1: Liability of Commercial Seller or
    Distributor for Harm Caused by
    Defective Products
    One engaged in the business of selling or
    otherwise distributing products who sells or
    distributes a defective product is subject to
    liability for harm to persons or property
    caused by the defect.
    § 2: Categories of Product Defect
    A product is defective when, at the time of
    sale or distribution, it contains a
    manufacturing defect, is defective in
    design, or is defective because of
    inadequate instructions or warnings. A
    product:
    (a) contains a manufacturing defect when
    the product departs from its intended
    design even though all possible care
    9
    was exercised in the preparation and
    marketing of the product;
    (b) is defective in design when the
    foreseeable risks of harm posed by the
    product could have been reduced or
    avoided by the adoption of a reasonable
    alternative design by the seller or other
    distributor, or a predecessor in the
    commercial chain of distribution, and
    the omission of the alternative design
    renders the product not reasonably safe;
    (c) is defective because of inadequate
    instructions or warnings when the
    foreseeable risks of harm posed by the
    product could have been reduced or
    avoided by the provision of reasonable
    instructions or warnings by the seller or
    other distributor, or a predecessor in the
    commercial chain of distribution, and
    the omission of the instructions or
    warnings renders the product not
    reasonably safe.
    Restatement (Third) of Torts §§ 1-2 (1998).
    Section 1 thus makes sellers liable only for the sale of
    products that are “defective,” and section 2 provides that a
    product may qualify as “defective” if it meets one of three sets
    of criteria. The criteria—which incorporate negligence
    concepts such as “foreseeable risk” and “care” directly into the
    definition of “defective”—amount to an express rejection of
    10
    the “no negligence in products liability” regime that the
    Supreme Court of Pennsylvania has endorsed in cases like
    Azzarello, 
    391 A.2d at 1025-1026
    . Several Justices of the
    Supreme Court of Pennsylvania have expressed the view that
    section 402A’s approach is antiquated and should be replaced.
    See, e.g., Phillips, 841 A.2d at 1015-1016 (Saylor, J., Castille,
    J., & Eakin, J., concurring) (“I believe that the time has come
    for this Court, in the manner of so many other jurisdictions, to
    expressly recognize the essential role of risk-utility balancing,
    a concept derived from negligence doctrine, in design defect
    litigation.”). Whether or when that Court will move from the
    Restatement (Second) to the Restatement (Third) of Torts are
    questions that have engendered much debate.
    They are also questions that have challenged this Court.
    In Berrier, we noted that the Supreme Court of Pennsylvania
    had not yet answered whether bystanders could recover on
    design defect claims. This question, in turn, required us to
    determine whether products liability cases are governed by the
    Restatement (Second) or the Restatement (Third) of Torts, and
    we stated that “[i]n the absence of a controlling decision by the
    Pennsylvania Supreme Court, a federal court applying that
    state’s substantive law must predict how Pennsylvania’s
    highest court would decide this case.” 
    563 F.3d at 45-46
    . After
    reviewing “relevant state precedents, analogous decisions,
    considered dicta, scholarly works, and . . . other reliable data,”
    
    id. at 46
    , we concluded that “if the Pennsylvania Supreme
    Court were confronted with this issue, it would adopt the
    Restatement (Third) of Torts, §§ 1 and 2,” id. at 40. Thus, we
    held that federal courts sitting in diversity and applying
    Pennsylvania law to products liability cases should look to
    sections 1 and 2 of the Restatement (Third) of Torts. Id. The
    precedential holding in Berrier, as set forth above, represents
    11
    this Court’s view of Pennsylvania’s products liability law.
    2.
    The District Court followed Berrier. In so doing it
    admitted evidence of the CPSC Standard as relevant to the
    amount of care Bell exercised, and it instructed the jury
    according to the framework set forth in sections 1 and 2 of the
    Restatement (Third) of Torts. The Covells contend that these
    decisions by the District Court were erroneous, because they
    would be improper under section 402A of the Restatement
    (Second) of Torts. They maintain that section 402A “has been
    the law in Pennsylvania since it was adopted in Webb v. Zern,
    [
    220 A.2d 853
     (Pa. 1966)]” and that “[n]o decision of the
    Pennsylvania Supreme Court has changed this.” If the District
    Court had applied the Restatement (Second) of Torts, it would
    not have permitted Bell to admit evidence of the CPSC
    Standard (because due care is irrelevant under the Restatement
    (Second) of Torts), and it would not have instructed the jury to
    consider whether the Giro Monza helmet was “unreasonably”
    dangerous (because the only relevant inquiry under the
    Restatement (Second) of Torts is whether the product itself
    was defective). The Covells maintain that each of these
    decisions by the District Court violated the doctrine of Erie
    Railroad Co. v. Tompkins, 
    304 U.S. 64
     (1938), as set forth in
    Van Dusen v. Barrack, 
    376 U.S. 612
     (1964), which requires
    federal courts sitting in diversity to apply state substantive law.
    
    376 U.S. at 638
     (Stating that, “[t]he nub of the policy that
    underlies [Erie] is that . . . a suit by a non-resident litigant in a
    federal court instead of in a State court a block away, should
    not lead to a substantially different result.”). In short, the
    Covells’ position is that section 402A is the law of
    Pennsylvania, and that when the District Court applied the
    12
    Restatement (Third) of Torts it permitted Bell to illicitly
    “utilize a transfer to achieve a result in federal court which
    could not have been achieved in the courts of the State where
    the action was filed.” 
    Id.
    In response, Bell directs us to our decision in Berrier,
    
    563 F.3d at 40
    , wherein we held that if confronted with the
    issue, the Supreme Court of Pennsylvania would apply
    sections 1 and 2 of the Restatement (Third) and not section
    402A of the Restatement (Second) of Torts. Such predictions
    by a federal court sitting in diversity are permissible absent a
    controlling decision by a state’s highest court. Nationwide
    Mut. Ins. Co. v. Buffetta, 
    230 F.3d 634
    , 637 (3d Cir. 2000).
    Bell’s position is that the District Court in this case did not err,
    because it followed Berrier’s precedential prediction of
    Pennsylvania law.
    We will affirm the District Court’s application of
    sections 1 and 2 of the Restatement (Third) of Torts. Much of
    the briefing from the parties, and all of the briefing from the
    amici, is devoted to which Restatement of Torts is best as a
    matter of policy, and which most logically extends the
    decisions of the Supreme Court of Pennsylvania—all of which
    are issues we waded through and resolved only two years ago
    when we decided Berrier. This means that, notwithstanding the
    volume of briefing in this case, the dispositive question we
    must answer is straightforward: do we follow Berrier?
    3.
    We will follow Berrier, and affirm the District Court.
    First, our Internal Operating Procedures instruct us to follow
    prior panels’ decisions:
    13
    Policy of Avoiding Intra-circuit Conflict of
    Precedent.
    It is the tradition of this court that the holding of
    a panel in a precedential opinion is binding on
    subsequent panels. Thus, no subsequent panel
    overrules the holding in a precedential opinion
    of a previous panel. Court en banc consideration
    is required to do so.
    3d Cir. I.O.P. 9.1 (2010).
    “Although a panel of this court is bound by, and lacks
    authority to overrule, a published decision of a prior panel, a
    panel may reevaluate a precedent in light of intervening
    authority,” including intervening decisions of state law but its
    highest court. Reich v. D.M. Sabia Co., 
    90 F.3d 854
    , 858 (3d.
    Cir. 1996) (internal citation omitted). In this vein, the Covells
    direct our attention to Bugosh v. I.U. North America, Inc., 
    942 A.2d 897
     (Pa. 2008), appeal dismissed as improvidently
    granted by 
    971 A.2d 1228
     (Pa. 2009). The Bugosh petitioner
    had sought a holding from the Supreme Court of Pennsylvania
    declaring that the Restatement (Third) and not the Restatement
    (Second) of Torts reflects the law of Pennsylvania. The Court
    granted certiorari on the issue in 2008, but in 2009 dismissed
    the appeal as improvidently granted. Bugosh, 
    971 A.2d 1228
    .
    The Covells urge us to hold that the dismissal of Bugosh
    indicates the Supreme Court of Pennsylvania’s contentment
    with the Restatement (Second) of Torts.
    We will not do so. Reading the tea leaves of a certiorari
    dismissal is risky business; one could just as reasonably
    14
    conclude that the dismissal here indicates the Court’s approval
    of Berrier as much as it indicates its approval of section 402A.
    That is why the Supreme Court of Pennsylvania has warned
    against reading between the lines of a certiorari dismissal:
    In the circumstance where we have accepted an
    issue by granting allowance of appeal, and this
    Court, after conducting our review of the issue,
    enters an order dismissing the appeal as having
    been improvidently granted, the effect is as
    though this Court never granted allowance of
    appeal. In other words, a dismissal as being
    improvidently granted has the exact same effect
    as if this Court had denied the petition for
    allowance of appeal (allocatur) in the first place.
    Where we dismiss an appeal as improvidently
    granted, the lower tribunal’s opinion and order
    stand as a decision of that court and this Court’s
    order has no precedential value.
    Commonwealth v. Tilghman, 
    673 A.2d 898
    , 904 (Pa. 1996)
    (emphasis in original); see also Salazar v. Allstate Ins. Co., 
    702 A.2d 1038
    , 1043 n.10 (Pa. 1997) (“[T]he fact that this court
    denied allowance of appeal . . . is no indication of our
    endorsement of the reasoning used by the Superior Court.”).
    We therefore conclude that, in light of the Supreme Court of
    Pennsylvania’s directives in Tilghman and Salazar, the
    Bugosh appeal was an intervening event, but not an
    intervening “authority” sufficient to revisit our holding in
    Berrier.
    Given that Bugosh is of no consequence, we conclude
    that the state of the law in Pennsylvania is exactly as it was
    15
    when we decided Berrier. Absent a change in Pennsylvania’s
    law, we see no reason to upset our precedent. Applying
    Berrier, we hold that the District Court did not err in using the
    Restatement (Third) of Torts to guide its decisions to admit
    evidence, and to frame its jury instructions.
    B.
    The Covells’ fallback contention is that even if sections
    1 and 2 of the Restatement (Third) of Torts were the law of
    Pennsylvania (i.e., even if the jury instructions in this case
    were correct), the District Court nonetheless erred by
    admitting evidence of the CPSC Standard. The Covells point
    out that the CPSC Standard is an “industry regulation” as
    described in section 4 of the Restatement (Third) of Torts,
    which—unlike sections 1 and 2—has not been cited or
    discussed by the Supreme Court of Pennsylvania. Cf. Berrier,
    
    563 F.3d at 40
     (holding only that the Supreme Court of
    Pennsylvania would apply sections 1 and 2 of the Restatement
    (Third) of Torts to products liability cases), The Covells
    maintain that if we affirm the District Court on this point we
    will apply section 4 before the Supreme Court of Pennsylvania
    does so—something to be avoided in a diversity case. Cf. Van
    Dusen, 
    376 U.S. at 638
    . We conclude that we need break no
    new ground today; we will affirm the District Court without
    resort to section 4 of the Restatement (Third) of Torts because
    the CPSC Standard was admissible pursuant to section 2.
    The Covells are correct that most jurisdictions applying
    the Restatement (Third) of Torts to products liability cases
    hold that evidence of compliance with product regulations is
    admissible to prove whether or not a product is defective. E.g.,
    Doyle v. Volkswagenwerk Aktiengesellschaft, 
    481 S.E.2d 16
    518, 521 (Ga. 1997). Courts in jurisdictions that have
    incorporated the entirety of the Restatement (Third) of Torts
    are free to admit such evidence under section 4, which
    provides:
    Noncompliance and Compliance with
    Product Safety Statutes or Regulations
    In connection with liability for defective design
    or inadequate instructions or warnings:
    (a) a product’s noncompliance with an
    applicable product safety statute or
    administrative regulation renders the product
    defective with respect to the risk sought to be
    reduced by the statute or regulation; and
    (b) a product’s compliance with an applicable
    product safety standard or administrative
    regulation is properly considered in
    determining whether the product is defective
    with respect to the risks sought to be reduced
    by the statute or regulation, but such
    compliance does not preclude as a matter of
    law a finding of a product defect.
    The District Court admitted such evidence in this case.
    It permitted Bell to demonstrate its compliance with the CPSC
    Standard, 
    16 C.F.R. § 1203
    , as evidence that its helmet was not
    “defective,” under section 2 of the Restatement (Third) of
    Torts.
    The Covells contend that this was reversible error
    17
    because section 4, not section 2, of the Restatement (Third) of
    Torts deals with governmental regulations, and—setting aside
    all debate over the validity of our holding in Berrier—there has
    been no indication from the Supreme Court of Pennsylvania
    that it would apply section 4. Because section 4 is not in play,
    they contend, there was no basis upon which the District Court
    could have admitted evidence of Bell’s compliance with the
    CPSC Standard, regardless of which version of the
    Restatement it applied. For support, they rely upon Lewis v.
    Coffing Hoist Division, Duff-Norton, Co., 
    528 A.2d 590
    , 594
    (Pa. 1987), which applied section 402A and held that evidence
    of industry practice or regulation is inadmissible in products
    liability cases. The Lewis Court reasoned that to admit
    industry practice and regulation in products liability cases
    would be to “improperly [bring] into the case concepts of
    negligence law.” 
    Id.
    We are not persuaded. As a threshold matter, we believe
    that to cite to Lewis is to beg the very question at issue in this
    appeal: may district courts applying Pennsylvania law to
    products liability cases admit evidence that is relevant to
    negligence-type concepts, like duty of care or forseeability? To
    rely upon Lewis (handed down in 1987, during the zenith of
    Pennsylvania’s no-negligence-in-strict-liability regime) would
    be to assume the question out of existence, because Lewis
    based its reasoning entirely upon the premise that there shall be
    no negligence in products liability. See 
    id.
     No longer can a
    court assume that premise is true—see Davis, 690 A.2d at 186
    (applying certain negligence principles to products
    liability)—which means, by extension, that no longer can a
    court assume Lewis accurately reflects the law of
    Pennsylvania, cf. Aetna Life & Casualty Co. v. Barthelemy, 
    33 F.3d 189
    , 193 (3d Cir. 1994) (“Where stops the reason, there
    18
    stops the rule.” (quoting Karl N. Llewellyn, Jurisprudence:
    Realism in Theory and Practice 217 (1962))).
    Whether the District Court erred in admitting evidence
    of the CPSC Standard thus depends not on pre-Berrier
    decisions like Lewis, but upon the post-Berrier legal
    framework that controls Pennsylvania products liability cases.
    In our view, it is highly unlikely that the Supreme Court of
    Pennsylvania would apply sections 1 and 2 of the Restatement
    (Third) of Torts (allowing negligence concepts), but not
    section 4 (providing for relevant industry regulation). We have
    difficulty imagining a negligence-friendly products liability
    regime that ignores compliance or non-compliance with
    pertinent state and federal regulations. At any rate, we need not
    determine whether the Supreme Court of Pennsylvania would
    adopt section 4 because we agree with Bell that evidence of its
    compliance with the CPSC Standard was relevant to section 2
    of the Restatement (Third) of Torts as applied in Berrier, and
    was admissible pursuant to the Federal Rules of Evidence. The
    relevancy provisions of the Federal Rules of Evidence control
    in this case because they are “arguably procedural.” See Kelly
    v. Crown Equip. Co., 
    970 F.2d 1273
    , 1278 (3d Cir. 1992)
    (Federal Rules of Evidence that are “arguably procedural”
    control in diversity actions, “notwithstanding Pennsylvania
    law to the contrary.”). Under the Federal Rules of Evidence,
    “‘[r]elevant evidence’ means evidence having any tendency to
    make the existence of any fact that is of consequence to the
    determination of the action more probable or less probable
    than it would be without the evidence,” Rule 401, and “[a]ll
    relevant evidence is admissible, except as otherwise provided
    by the Constitution of the United States, by Act of Congress,
    by these rules, or by other rules prescribed by the Supreme
    Court pursuant to statutory authority,” Rule 402.
    19
    Applying this standard, we conclude that evidence of
    Bell’s compliance with the CPSC Standard was relevant to the
    jury’s inquiry because it went to at least two facts of
    consequence under section 2 of the Restatement (Third) of
    Torts, section 2. First, the CPSC Standard sets forth detailed
    rules for impact resistance and testing, and for labels and
    warning—both on the helmet and its sales packaging.
    Evidence that Bell complied with the CPSC Standard’s
    requirement for impact resistance testing makes it “more
    probable,” Rule 401, that “all possible care was exercised in
    the preparation and marketing of the product,” Restatement
    (Third) of Torts § 2(a). Second, evidence that Bell complied
    with the CPSC Standard makes it “less probable,” Rule 401,
    that “the foreseeable risks of harm posed by the product could
    have been reduced or avoided by the provision of reasonable
    instructions or warnings,” Restatement (Third) of Torts § 2(c).
    Of course, such evidence was not conclusive on these points,
    but it was relevant and therefore presumptively admissible
    under the Federal Rules.
    Our conclusion in this respect—i.e., that industry
    standards and government regulations are relevant to facts of
    consequence in this case—is also in line with the Commentary
    to section 2 of the Restatement (Third) of Torts. Comment (b)
    explicitly states that industry regulations may be relevant to a
    plaintiff’s case under section 2, irrespective of section 4:
    Section 4, dealing with violations of statutory
    and regulatory norms, also provides an alternate
    method of establishing defect. A plaintiff is not
    required to establish the standard for design or
    warning under § 2, but merely to identify a
    20
    government-imposed standard.
    Id. § 2 comment (b). Further, comment (d) states that
    defendants may admit evidence of industry practice to show
    that an alternative design would not have made their product
    safer:
    The defendant is thus allowed to introduce
    evidence with regard to industry practice that
    bears on whether the omission of an alternative
    design rendered the product not reasonably safe.
    While such evidence is admissible, it is not
    necessarily dispositive.
    Id. § 2 comment (d). The commentary to section 2 of the
    Restatement (Third) of Torts thus buttresses our conclusion
    that evidence related to the CPSC Standard was properly
    admitted in this case.
    In sum, we conclude that we need not consider whether
    evidence of the CPSC Standard was admissible pursuant to
    section 4 of the Restatement (Third) of Torts because in this
    case the evidence was admissible pursuant to section 2, as
    applied in Berrier. We will therefore affirm the District Court.
    *****
    We have considered all of the arguments advanced by
    the parties and conclude that no further discussion is
    necessary. The judgment of the District Court will be
    AFFIRMED.
