    HARRINGTON, WARDEN v. RICHTER
    CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
    THE NINTH CIRCUIT
    No. 09–587.      Argued October 12, 2010—Decided January 19, 2011
    In 1994, deputies called to drug dealer Johnson’s California home found
    Johnson wounded and Klein fatally wounded. Johnson claimed that
    he was shot in his bedroom by respondent Richter’s codefendant,
    Branscombe; that he found Klein on the living room couch; and that
    his gun safe, a pistol, and cash were missing. His account was cor
    roborated by evidence at the scene, including, relevant here, spent
    shell casings, blood spatters, and blood pooled in the bedroom door
    way. Investigators took a blood sample from a wall near the bedroom
    door, but not from the blood pool. A search of Richter’s home turned
    up the safe and ammunition matching evidence at the scene. After
    his arrest on murder and other charges, Richter initially denied his
    involvement, but later admitted disposing of Johnson’s and
    Branscombe’s guns. The prosecution initially built its case on John
    son’s testimony and the circumstantial evidence, but it adjusted its
    approach after Richter’s counsel, in his opening statement, outlined
    the theory that Branscombe shot Johnson in self-defense and that
    Klein was killed in the crossfire in the bedroom doorway, and
    stressed the lack of forensic support for the prosecution’s case. The
    prosecution then decided to call an expert in blood pattern evidence,
    who testified that it was unlikely that Klein had been shot outside
    the living room and then moved to the couch, and a serologist, who
    testified that the blood sample taken near the blood pool could be
    Johnson’s but not Klein’s. Under cross-examination, she conceded
    that she had not tested the sample for cross-contamination and that
    a degraded sample would make it difficult to tell if it had blood of
    Klein’s type. Defense counsel called Richter to tell his conflicting
    version of events and called other witnesses to corroborate Richter’s
    version. Richter was convicted and sentenced to life without parole.

    Syllabus
    He later sought habeas relief from the California Supreme Court, as
    serting, inter alia, that his counsel provided ineffective assistance,
    see Strickland v. Washington, 
    466 U. S. 668
    , when he failed to pre
    sent expert testimony on blood evidence, because it could have dis
    closed the blood pool’s source and bolstered Richter’s theory. He also
    offered affidavits from forensics experts to support his claim. The
    court denied the petition in a one-sentence summary order. Subse
    quently, he reasserted his state claims in a federal habeas petition.
    The District Court denied his petition. A Ninth Circuit panel af
    firmed, but the en banc court reversed. Initially it questioned
    whether 
    28 U. S. C. §2254
    (d)—which, as amended by the Antiterror
    ism and Effective Death Penalty Act of 1996 (AEDPA), limits the
    availability of federal habeas relief for claims previously “adjudicated
    on the merits” in state court—applied to Richter’s petition, since the
    State Supreme Court issued only a summary denial. But it found the
    state-court decision unreasonable anyway. In its view, trial counsel
    was deficient in failing to consult blood evidence experts in planning
    a trial strategy and in preparing to rebut expert evidence the prose
    cution might—and later did—offer.
    Held:
    1. Section 2254(d) applies to Richter’s petition, even though the
    state court’s order was unaccompanied by an opinion explaining the
    court’s reasoning. Pp. 7–10.
    (a) By its terms, §2254(d) bars relitigation of a claim “adjudicated
    on the merits” in state court unless, among other exceptions, the ear
    lier state-court “decision” involved “an unreasonable application” of
    “clearly established Federal law, as determined by” this Court,
    §2254(d)(1). Nothing in its text—which refers only to a “decision” re
    sulting “from an adjudication”—requires a statement of reasons.
    Where the state-court decision has no explanation, the habeas peti
    tioner must still show there was no reasonable basis for the state
    court to deny relief. There is no merit to the assertion that applying
    §2254(d) when state courts issue summary rulings will encourage
    those courts to withhold explanations. The issuance of summary dis
    positions can enable state judiciaries to concentrate resources where
    most needed. Pp. 7–9.
    (b) Nor is there merit to Richter’s argument that §2254(d) does
    not apply because the California Supreme Court did not say it was
    adjudicating his claim “on the merits.” When a state court has de
    nied relief, adjudication on the merits can be presumed absent any
    contrary indication or state-law procedural principles. The presump
    tion may be overcome by a more likely explanation for the state
    court’s decision, but Richter does not make that showing here. Pp. 9–
    10.

    Syllabus
    2. Richter was not entitled to the habeas relief ordered by the
    Ninth Circuit. Pp. 10–24.
    (a) That court failed to accord the required deference to the deci
    sion of a state court adjudicating the same claims later presented in
    the federal habeas petition. Its opinion shows an improper under
    standing of §2254(d)’s unreasonableness standard and operation in
    the context of a Strickland claim. Asking whether the state court’s
    application of Strickland’s standard was unreasonable is different
    from asking whether defense counsel’s performance fell below that
    standard. Under AEDPA, a state court must be granted a deference
    and latitude that are not in operation in a case involving direct re
    view under Strickland. A state court’s determination that a claim
    lacks merit precludes federal habeas relief so long as “fair-minded ju
    rists could disagree” on the correctness of that decision. Yarborough
    v. Alvarado, 
    541 U. S. 652
    , 664. And the more general the rule being
    considered, “the more leeway courts have in reaching outcomes in
    case-by-case determinations.” 
    Ibid.
     The Ninth Circuit explicitly con
    ducted a de novo review and found a Strickland violation; it then de
    clared without further explanation that the state court’s contrary de
    cision was unreasonable. But §2254(d) requires a habeas court to
    determine what arguments or theories supported, or could have sup
    ported, the state-court decision; and then to ask whether it is possible
    fair-minded jurists could disagree that those arguments or theories
    are inconsistent with a prior decision of this Court. AEDPA’s unrea
    sonableness standard is not a test of the confidence of a federal ha
    beas court in the conclusion it would reach as a de novo matter. Even
    a strong case for relief does not make the state court’s contrary con
    clusion unreasonable. Section 2254(d) is designed to confirm that
    state courts are the principal forum for asserting constitutional chal
    lenges to state convictions. Pp. 10–14.
    (b) The Ninth Circuit erred in concluding that Richter demon
    strated an unreasonable application of Strickland by the state court.
    Pp. 14–23.
    (1) Richter could have secured relief in state court only by
    showing both that his counsel provided deficient assistance and that
    prejudice resulted. To be deficient, counsel’s representation must
    have fallen “below an objective standard of reasonableness,” Strick
    land, 
    466 U. S., at 688
    ; and there is a “strong presumption” that
    counsel’s representation is within the “wide range” of reasonable pro
    fessional assistance, 
    id., at 689
    . The question is whether counsel
    made errors so fundamental that counsel was not functioning as the
    counsel guaranteed by the Sixth Amendment. Prejudice requires
    demonstrating “a reasonable probability that, but for counsel’s unpro
    fessional errors, the result of the proceeding would have been differ
    4                      HARRINGTON v. RICHTER
    Syllabus
    ent.” 
    Id., at 694
    . “Surmounting Strickland’s high bar is never . . .
    easy.” Padilla v. Kentucky, 559 U. S.___, ___. Strickland can func
    tion as a way to escape rules of waiver and forfeiture. The question is
    whether an attorney’s representation amounted to incompetence un
    der prevailing professional norms, not whether it deviated from best
    practices or most common custom. Establishing that a state court’s
    application of Strickland was unreasonable under §2254(d) is even
    more difficult, since both standards are “highly deferential,” 466 U. S,
    at 689, and since Strickland’s general standard has a substantial
    range of reasonable applications. The question under §2254(d) is not
    whether counsel’s actions were reasonable, but whether there is any
    reasonable argument that counsel satisfied Strickland’s deferential
    standard. Pp. 14–16.
    (2) The Ninth Circuit erred in holding that because Richter’s
    attorney had not consulted forensic blood experts or introduced ex
    pert evidence, the State Supreme Court could not reasonably have
    concluded counsel provided adequate representation.
    A state court could reasonably conclude that a competent attorney
    could elect a strategy that did not require using blood evidence ex
    perts. Rare are the situations in which the latitude counsel enjoys
    will be limited to any one technique or approach. There were any
    number of experts whose insight might have been useful to the de
    fense. Counsel is entitled to balance limited resources in accord with
    effective trial tactics and strategies. In finding otherwise the Ninth
    Circuit failed to “reconstruct the circumstances of counsel’s chal
    lenged conduct” and “evaluate the conduct from counsel’s perspective
    at the time.” Strickland, supra, at 689. Given the many factual dif
    ferences between the prosecution and defense versions of events, it
    was far from evident at the time of trial that the blood source was
    central to Richter’s case. And relying on “the harsh light of hind
    sight” to cast doubt on a trial that took place over 15 years ago is pre
    cisely what Strickland and AEDPA seek to prevent. See Bell v. Cone,
    
    535 U. S. 685
    , 702. Even had the value of expert testimony been ap
    parent, it would be reasonable to conclude that a competent attorney
    might elect not to use it here, where counsel had reason to question
    the truth of his client’s account. Making blood evidence a central is
    sue could also have led the prosecution to produce its own expert
    analysis, possibly destroying Richter’s case, or distracted the jury
    with esoteric questions of forensic science. Defense counsel’s opening
    statement may have inspired the prosecution to present forensic evi
    dence, but that shows only that the defense strategy did not work out
    as well as hoped. In light of the record here there was no basis to
    rule that the state court’s determination was unreasonable.
    The Court of Appeals erred in dismissing such concern as an inac
    Cite as: 562 U. S. ____ (2011)                        5
    Syllabus
    curate account of counsel’s actual thinking, since Strickland exam
    ined only the objective reasonableness of counsel’s actions. As to
    whether counsel was constitutionally deficient for not preparing ex
    pert testimony as a response to the prosecution’s, an attorney may
    not be faulted for a reasonable miscalculation or lack of foresight or
    for failing to prepare for remote possibilities. Here, even if counsel
    was mistaken, the prosecution itself did not expect to present forensic
    testimony until the eve of trial. Thus, it is at least debatable whether
    counsel’s error was so fundamental as to call the trial’s fairness into
    doubt. Even if counsel should have foreseen the prosecution’s tactic,
    Richter would still need to show it was indisputable that Strickland
    required his attorney to rely on a rebuttal witness rather than on
    cross-examination to discredit the witnesses, but Strickland imposes
    no such requirement. And while it is possible an isolated error can
    constitute ineffective assistance if it is sufficiently egregious, it is dif
    ficult to establish ineffective assistance where counsel’s overall per
    formance reflects active and capable advocacy. Pp. 16–22.
    (3) The Ninth Circuit also erred in concluding that Richter had
    established prejudice under Strickland, which asks whether it is
    “reasonably likely” the verdict would have been different, 
    466 U. S., at 696
    , not whether a court can be certain counsel’s performance had
    no effect on the outcome or that reasonable doubt might have been
    established had counsel acted differently. There must be a substan
    tial likelihood of a different result. The State Supreme Court could
    have reasonably concluded that Richter’s prejudice evidence fell short
    of this standard. His expert serology evidence established only a
    theoretical possibility of Klein’s blood being in the blood pool; and at
    trial, defense counsel extracted a similar concession from the prose
    cution’s expert. It was also reasonable to find Richter had not estab
    lished prejudice given that he offered no evidence challenging other
    conclusions of the prosecution’s experts, e.g., that the blood sample
    matched Johnson’s blood type. There was, furthermore, sufficient
    conventional circumstantial evidence pointing to Richter’s guilt, in
    cluding, e.g., the items found at his home. Pp. 22–23.

    KELLY HARRINGTON, WARDEN, PETITIONER v.
    JOSHUA RICHTER
    ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
    APPEALS FOR THE NINTH CIRCUIT
    [January 19, 2011]
    JUSTICE KENNEDY delivered the opinion of the Court.
    The writ of habeas corpus stands as a safeguard against
    imprisonment of those held in violation of the law. Judges
    must be vigilant and independent in reviewing petitions
    for the writ, a commitment that entails substantial judi
    cial resources. Those resources are diminished and mis
    spent, however, and confidence in the writ and the law it
    vindicates undermined, if there is judicial disregard for
    the sound and established principles that inform its
    proper issuance. That judicial disregard is inherent in the
    opinion of the Court of Appeals for the Ninth Circuit here
    under review. The Court of Appeals, in disagreement with
    the contrary conclusions of the Supreme Court of the State
    of California and of a United States District Court, or
    dered habeas corpus relief granted to set aside the convic
    tion of Joshua Richter, respondent here. This was clear
    error.
    Under 
    28 U. S. C. §2254
    (d), the availability of federal
    habeas relief is limited with respect to claims previously
    “adjudicated on the merits” in state-court proceedings.
    The first inquiry this case presents is whether that pro
    2                HARRINGTON v. RICHTER
    Opinion of the Court
    vision applies when state-court relief is denied without
    an accompanying statement of reasons. If it does, the
    question is whether the Court of Appeals adhered to the
    statute’s terms, in this case as it relates to ineffective
    assistance claims judged by the standard set forth in
    Strickland v. Washington, 
    466 U. S. 668
     (1984). A second
    case decided today, Premo v. Moore, post, p. ___, presents
    similar issues. Here, as in that case, it is necessary to
    reverse the Court of Appeals for failing to accord required
    deference to the decision of a state court.
    I
    It is necessary to begin by discussing the details of a
    crime committed more than a decade and a half ago.
    A
    Sometime after midnight on December 20, 1994, sher
    iff’s deputies in Sacramento County, California, arrived at
    the home of a drug dealer named Joshua Johnson. Hours
    before, Johnson had been smoking marijuana in the com
    pany of Richter and two other men, Christian Branscombe
    and Patrick Klein. When the deputies arrived, however,
    they found only Johnson and Klein. Johnson was hysteri
    cal and covered in blood. Klein was lying on a couch in
    Johnson’s living room, unconscious and bleeding. Klein
    and Johnson each had been shot twice. Johnson recov
    ered; Klein died of his wounds.
    Johnson gave investigators this account: After falling
    asleep, he awoke to find Richter and Branscombe in his
    bedroom, at which point Branscombe shot him. Johnson
    heard more gunfire in the living room and the sound of his
    assailants leaving. He got up, found Klein bleeding on the
    living room couch, and called 911. A gun safe, a pistol,
    and $6,000 cash, all of which had been in the bedroom,
    were missing.
    Cite as: 562 U. S. ____ (2011)           3
    Opinion of the Court
    Evidence at the scene corroborated Johnson’s account.
    Investigators found spent shell casings in the bedroom
    (where Johnson said he had been shot) and in the living
    room (where Johnson indicated Klein had been shot). In
    the living room there were two casings, a .32 caliber and a
    .22 caliber. One of the bullets recovered from Klein’s body
    was a .32 and the other was a .22. In the bedroom there
    were two more casings, both .32 caliber. In addition detec
    tives found blood spatter near the living room couch and
    bloodstains in the bedroom. Pools of blood had collected in
    the kitchen and the doorway to Johnson’s bedroom. Inves
    tigators took only a few blood samples from the crime
    scene. One was from a blood splash on the wall near
    the bedroom doorway, but no sample was taken from the
    doorway blood pool itself.
    Investigators searched Richter’s residence and found
    Johnson’s gun safe, two boxes of .22-caliber ammunition,
    and a gun magazine loaded with cartridges of the same
    brand and type as the boxes. A ballistics expert later
    concluded the .22-caliber bullet that struck Klein and
    the .22-caliber shell found in the living room matched the
    ammunition found in Richter’s home and bore markings
    consistent with the model of gun for which the magazine
    was designed.
    Richter and Branscombe were arrested. At first Richter
    denied involvement. He would later admit taking John
    son’s pistol and disposing of it and of the .32-caliber
    weapon Branscombe used to shoot Johnson and Klein.
    Richter’s counsel produced Johnson’s missing pistol, but
    neither of the guns used to shoot Johnson and Klein was
    found.
    B
    Branscombe and Richter were tried together on charges
    of murder, attempted murder, burglary, and robbery.
    Only Richter’s case is presented here.
    4                HARRINGTON v. RICHTER
    Opinion of the Court
    The prosecution built its case on Johnson’s testimony
    and on circumstantial evidence. Its opening statement
    took note of the shell casings found at the crime scene and
    the ammunition and gun safe found at Richter’s residence.
    Defense counsel offered explanations for the circumstan
    tial evidence and derided Johnson as a drug dealer, a
    paranoid, and a trigger-happy gun fanatic who had drawn
    a pistol on Branscombe and Richter the last time he had
    seen them. And there were inconsistencies in Johnson’s
    story. In his 911 call, for instance, Johnson first said
    there were four or five men who had broken into his
    house, not two; and in the call he did not identify Richter
    and Branscombe among the intruders.
    Blood evidence does not appear to have been part of the
    prosecution’s planned case prior to trial, and investigators
    had not analyzed the few blood samples taken from the
    crime scene. But the opening statement from the defense
    led the prosecution to alter its approach. Richter’s attor
    ney outlined the theory that Branscombe had fired on
    Johnson in self-defense and that Klein had been killed not
    on the living room couch but in the crossfire in the bed
    room doorway. Defense counsel stressed deficiencies in
    the investigation, including the absence of forensic support
    for the prosecution’s version of events.
    The prosecution took steps to adjust to the counterat
    tack now disclosed. Without advance notice and over the
    objection of Richter’s attorney, one of the detectives who
    investigated the shootings testified for the prosecution as
    an expert in blood pattern evidence. He concluded it was
    unlikely Klein had been shot outside the living room and
    then moved to the couch, given the patterns of blood on
    Klein’s face, as well as other evidence including “high
    velocity” blood spatter near the couch consistent with the
    location of a shooting. The prosecution also offered testi
    mony from a serologist. She testified the blood sample
    taken near the pool by the bedroom door could be John
    Cite as: 562 U. S. ____ (2011)           5
    Opinion of the Court
    son’s but not Klein’s.
    Defense counsel’s cross-examination probed weaknesses
    in the testimony of these two witnesses. The detective
    who testified on blood patterns acknowledged that his
    inferences were imprecise, that it was unlikely Klein had
    been lying down on the couch when shot, and that he could
    not say the blood in the living room was from either of
    Klein’s wounds. Defense counsel elicited from the serolo
    gist a concession that she had not tested the bedroom
    blood sample for cross-contamination. She said that if the
    year-old sample had degraded, it would be difficult to tell
    whether blood of Klein’s type was also present in the
    sample.
    For the defense, Richter’s attorney called seven wit
    nesses. Prominent among these was Richter himself.
    Richter testified he and Branscombe returned to Johnson’s
    house just before the shootings in order to deliver some
    thing to one of Johnson’s roommates. By Richter’s ac
    count, Branscombe entered the house alone while Richter
    waited in the driveway; but after hearing screams and
    gunshots, Richter followed inside. There he saw Klein
    lying not on the couch but in the bedroom doorway, with
    Johnson on the bed and Branscombe standing in the
    middle of the room. According to Richter, Branscombe
    said he shot at Johnson and Klein after they attacked him.
    Other defense witnesses provided some corroboration for
    Richter’s story. His former girlfriend, for instance, said
    she saw the gun safe at Richter’s house shortly before the
    shootings.
    The jury returned a verdict of guilty on all charges.
    Richter was sentenced to life without parole. On appeal,
    his conviction was affirmed. People v. Branscombe, 
    72 Cal. Rptr. 2d 773
     (Cal. App. 1998) (officially depublished).
    The California Supreme Court denied a petition for re
    view, People v. Branscombe, No. S069751, 
    1998 Cal. LEXIS 4252
     (June 24, 1998), and Richter did not file a
    6                HARRINGTON v. RICHTER
    Opinion of the Court
    petition for certiorari with this Court.    His conviction
    became final.
    C
    Richter later petitioned the California Supreme Court
    for a writ of habeas corpus. He asserted a number of
    grounds for relief, including ineffective assistance of coun
    sel. As relevant here, he claimed his counsel was deficient
    for failing to present expert testimony on serology, pathol
    ogy, and blood spatter patterns, testimony that, he argued,
    would disclose the source of the blood pool in the bedroom
    doorway. This, he contended, would bolster his theory
    that Johnson had moved Klein to the couch.
    He offered affidavits from three types of forensic ex
    perts. First, he provided statements from two blood se
    rologists who said there was a possibility Klein’s blood was
    intermixed with blood of Johnson’s type in the sample
    taken from near the pool in the bedroom doorway. Second,
    he provided a statement from a pathologist who said the
    blood pool was too large to have come from Johnson given
    the nature of his wounds and his own account of his ac
    tions while waiting for the police. Third, he provided a
    statement from an expert in bloodstain analysis who said
    the absence of “a large number of satellite droplets” in
    photographs of the area around the blood in the bedroom
    doorway was inconsistent with the blood pool coming from
    Johnson as he stood in the doorway. App. 118. Richter
    argued this evidence established the possibility that the
    blood in the bedroom doorway came from Klein, not John
    son. If that were true, he argued, it would confirm his
    account, not Johnson’s. The California Supreme Court
    denied Richter’s petition in a one-sentence summary
    order. See In re Richter, No. S082167 (Mar. 28, 2001),
    App. to Pet. for Cert. 22a. Richter did not seek certiorari
    from this Court.
    After the California Supreme Court issued its summary
    Cite as: 562 U. S. ____ (2011)            7
    Opinion of the Court
    order denying relief, Richter filed a petition for habeas
    corpus in United States District Court for the Eastern
    District of California. He reasserted the claims in his
    state petition. The District Court denied his petition, and
    a three-judge panel of the Court of Appeals for the Ninth
    Circuit affirmed. See Richter v. Hickman, 
    521 F. 3d 1222
    (2008). The Court of Appeals granted rehearing en banc
    and reversed the District Court’s decision. See Richter v.
    Hickman, 
    578 F. 3d 944
     (2009).
    As a preliminary matter, the Court of Appeals ques
    tioned whether 
    28 U. S. C. §2254
    (d) was applicable to
    Richter’s petition, since the California Supreme Court
    issued only a summary denial when it rejected his Strick
    land claims; but it determined the California decision was
    unreasonable in any event and that Richter was entitled
    to relief. The court held Richter’s trial counsel was defi
    cient for failing to consult experts on blood evidence in
    determining and pursuing a trial strategy and in prepar
    ing to rebut expert evidence the prosecution might—and
    later did—offer. Four judges dissented from the en banc
    decision.
    We granted certiorari. 559 U. S. ___ (2010).
    II
    The statutory authority of federal courts to issue habeas
    corpus relief for persons in state custody is provided by 
    28 U. S. C. §2254
    , as amended by the Antiterrorism and
    Effective Death Penalty Act of 1996 (AEDPA). The text of
    §2254(d) states:
    “An application for a writ of habeas corpus on behalf
    of a person in custody pursuant to the judgment of a
    State court shall not be granted with respect to any
    claim that was adjudicated on the merits in State
    court proceedings unless the adjudication of the
    claim—
    “(1) resulted in a decision that was contrary to, or
    8                HARRINGTON v. RICHTER
    Opinion of the Court
    involved an unreasonable application of, clearly estab
    lished Federal law, as determined by the Supreme
    Court of the United States; or
    “(2) resulted in a decision that was based on an un
    reasonable determination of the facts in light of the
    evidence presented in the State court proceeding.”
    As an initial matter, it is necessary to decide whether
    §2254(d) applies when a state court’s order is unaccompa
    nied by an opinion explaining the reasons relief has been
    denied.
    By its terms §2254(d) bars relitigation of any claim
    “adjudicated on the merits” in state court, subject only to
    the exceptions in §§2254(d)(1) and (d)(2). There is no text
    in the statute requiring a statement of reasons. The
    statute refers only to a “decision,” which resulted from an
    “adjudication.” As every Court of Appeals to consider the
    issue has recognized, determining whether a state court’s
    decision resulted from an unreasonable legal or factual
    conclusion does not require that there be an opinion from
    the state court explaining the state court’s reasoning. See
    Chadwick v. Janecka, 
    312 F. 3d 597
    , 605–606 (CA3 2002);
    Wright v. Secretary for Dept. of Corrections, 
    278 F. 3d 1245
    , 1253–1254 (CA11 2002); Sellan v. Kuhlman, 
    261 F. 3d 303
    , 311–312 (CA2 2001); Bell v. Jarvis, 
    236 F. 3d 149
    , 158–162 (CA4 2000) (en banc); Harris v. Stovall, 
    212 F. 3d 940
    , 943, n. 1 (CA6 2000); Aycox v. Lytle, 
    196 F. 3d 1174
    , 1177–1178 (CA10 1999); James v. Bowersox, 
    187 F. 3d 866
    , 869 (CA8 1999). And as this Court has ob
    served, a state court need not cite or even be aware of our
    cases under §2254(d). Early v. Packer, 
    537 U. S. 3
    , 8
    (2002) (per curiam). Where a state court’s decision is
    unaccompanied by an explanation, the habeas petitioner’s
    burden still must be met by showing there was no reason
    able basis for the state court to deny relief. This is so
    whether or not the state court reveals which of the ele
    Cite as: 562 U. S. ____ (2011)            9
    Opinion of the Court
    ments in a multipart claim it found insufficient, for
    §2254(d) applies when a “claim,” not a component of one,
    has been adjudicated.
    There is no merit to the assertion that compliance with
    §2254(d) should be excused when state courts issue sum
    mary rulings because applying §2254(d) in those cases will
    encourage state courts to withhold explanations for their
    decisions. Opinion-writing practices in state courts are
    influenced by considerations other than avoiding scrutiny
    by collateral attack in federal court. Cf. In re Robbins, 
    18 Cal. 4th 770
    , 778, n. 1, 
    959 P. 2d 311
    , 316, n. 1 (1998)
    (state procedures limiting habeas are “a means of protect
    ing the integrity of our own appeal and habeas corpus
    process,” rather than a device for “insulating our judg
    ments from federal court review” (emphasis deleted)). At
    the same time, requiring a statement of reasons could
    undercut state practices designed to preserve the integrity
    of the case-law tradition. The issuance of summary dispo
    sitions in many collateral attack cases can enable a state
    judiciary to concentrate its resources on the cases where
    opinions are most needed. See Brief for California Attor
    neys for Criminal Justice et al. as Amici Curiae 8 (noting
    that the California Supreme Court disposes of close to
    10,000 cases a year, including more than 3,400 original
    habeas corpus petitions).
    There is no merit either in Richter’s argument that
    §2254(d) is inapplicable because the California Supreme
    Court did not say it was adjudicating his claim “on the
    merits.” The state court did not say it was denying the
    claim for any other reason. When a federal claim has been
    presented to a state court and the state court has denied
    relief, it may be presumed that the state court adjudicated
    the claim on the merits in the absence of any indication or
    state-law procedural principles to the contrary. Cf. Harris
    v. Reed, 
    489 U. S. 255
    , 265 (1989) (presumption of a merits
    determination when it is unclear whether a decision ap
    10                HARRINGTON v. RICHTER
    Opinion of the Court
    pearing to rest on federal grounds was decided on another
    basis).
    The presumption may be overcome when there is reason
    to think some other explanation for the state court’s deci
    sion is more likely. See, e.g., Ylst v. Nunnemaker, 
    501 U. S. 797
    , 803 (1991). Richter, however, does not make
    that showing. He mentions the theoretical possibility that
    the members of the California Supreme Court may not
    have agreed on the reasons for denying his petition. It is
    pure speculation, however, to suppose that happened in
    this case. And Richter’s assertion that the mere possibil
    ity of a lack of agreement prevents any attribution of
    reasons to the state court’s decision is foreclosed by prece
    dent. See 
    ibid.
    As has been noted before, the California courts or Legis
    lature can alter the State’s practices or elaborate more
    fully on their import. See Evans v. Chavis, 
    546 U. S. 189
    ,
    197, 199 (2006). But that has not occurred here. This
    Court now holds and reconfirms that §2254(d) does not
    require a state court to give reasons before its decision can
    be deemed to have been “adjudicated on the merits.”
    Richter has failed to show that the California Supreme
    Court’s decision did not involve a determination of the
    merits of his claim. Section 2254(d) applies to his petition.
    III
    Federal habeas relief may not be granted for claims
    subject to §2254(d) unless it is shown that the earlier state
    court’s decision “was contrary to” federal law then clearly
    established in the holdings of this Court, §2254(d)(1);
    Williams v. Taylor, 
    529 U. S. 362
    , 412 (2000); or that
    it “involved an unreasonable application of” such law,
    §2254(d)(1); or that it “was based on an unreasonable
    determination of the facts” in light of the record before the
    state court, §2254(d)(2).
    The Court of Appeals relied on the second of these ex
    Cite as: 562 U. S. ____ (2011)          11
    Opinion of the Court
    ceptions to §2254(d)’s relitigation bar, the exception in
    §2254(d)(1) permitting relitigation where the earlier state
    decision resulted from an “unreasonable application of”
    clearly established federal law. In the view of the Court of
    Appeals, the California Supreme Court’s decision on Rich
    ter’s ineffective-assistance claim unreasonably applied the
    holding in Strickland. The Court of Appeals’ lengthy
    opinion, however, discloses an improper understanding of
    §2254(d)’s unreasonableness standard and of its operation
    in the context of a Strickland claim.
    The pivotal question is whether the state court’s appli
    cation of the Strickland standard was unreasonable. This
    is different from asking whether defense counsel’s per
    formance fell below Strickland’s standard. Were that the
    inquiry, the analysis would be no different than if, for
    example, this Court were adjudicating a Strickland claim
    on direct review of a criminal conviction in a United States
    district court. Under AEDPA, though, it is a necessary
    premise that the two questions are different. For purposes
    of §2254(d)(1), “an unreasonable application of federal law
    is different from an incorrect application of federal law.”
    Williams, 
    supra, at 410
    . A state court must be granted a
    deference and latitude that are not in operation when the
    case involves review under the Strickland standard itself.
    A state court’s determination that a claim lacks merit
    precludes federal habeas relief so long as “fairminded
    jurists could disagree” on the correctness of the state
    court’s decision. Yarborough v. Alvarado, 
    541 U. S. 652
    ,
    664 (2004).        And as this Court has explained,
    “[E]valuating whether a rule application was unreason
    able requires considering the rule’s specificity. The more
    general the rule, the more leeway courts have in reaching
    outcomes in case-by-case determinations.” 
    Ibid.
     “[I]t is
    not an unreasonable application of clearly established
    Federal law for a state court to decline to apply a specific
    legal rule that has not been squarely established by this
    12               HARRINGTON v. RICHTER
    Opinion of the Court
    Court.” Knowles v. Mirzayance, 556 U. S. ___, ___ (2009)
    (slip op., at 9–10) (internal quotation marks omitted).
    Here it is not apparent how the Court of Appeals’ analy
    sis would have been any different without AEDPA. The
    court explicitly conducted a de novo review, 
    578 F. 3d, at 952
    ; and after finding a Strickland violation, it declared,
    without further explanation, that the “state court’s deci
    sion to the contrary constituted an unreasonable applica
    tion of Strickland.” 
    578 F. 3d, at 969
    . AEDPA demands
    more. Under §2254(d), a habeas court must determine
    what arguments or theories supported or, as here, could
    have supported, the state court’s decision; and then it
    must ask whether it is possible fairminded jurists could
    disagree that those arguments or theories are inconsistent
    with the holding in a prior decision of this Court. The
    opinion of the Court of Appeals all but ignored “the only
    question that matters under §2254(d)(1).” Lockyer v.
    Andrade, 
    538 U. S. 63
    , 71 (2003).
    The Court of Appeals appears to have treated the un
    reasonableness question as a test of its confidence in the
    result it would reach under de novo review: Because the
    Court of Appeals had little doubt that Richter’s Strickland
    claim had merit, the Court of Appeals concluded the state
    court must have been unreasonable in rejecting it. This
    analysis overlooks arguments that would otherwise justify
    the state court’s result and ignores further limitations of
    §2254(d), including its requirement that the state court’s
    decision be evaluated according to the precedents of this
    Court. See Renico v. Lett, 559 U. S. ___, ___ (2010) (slip
    op., at 11–12). It bears repeating that even a strong case
    for relief does not mean the state court’s contrary conclu
    sion was unreasonable. See Lockyer, 
    supra, at 75
    .
    If this standard is difficult to meet, that is because it
    was meant to be. As amended by AEDPA, §2254(d) stops
    short of imposing a complete bar on federal court relitiga
    tion of claims already rejected in state proceedings. Cf.
    Cite as: 562 U. S. ____ (2011)           13
    Opinion of the Court
    Felker v. Turpin, 
    518 U. S. 651
    , 664 (1996) (discussing
    AEDPA’s “modified res judicata rule” under §2244). It
    preserves authority to issue the writ in cases where there
    is no possibility fairminded jurists could disagree that the
    state court’s decision conflicts with this Court’s prece
    dents. It goes no farther. Section 2254(d) reflects the view
    that habeas corpus is a “guard against extreme malfunc
    tions in the state criminal justice systems,” not a substi
    tute for ordinary error correction through appeal. Jackson
    v. Virginia, 
    443 U. S. 307
    , 332, n. 5 (1979) (Stevens, J.,
    concurring in judgment). As a condition for obtaining
    habeas corpus from a federal court, a state prisoner must
    show that the state court’s ruling on the claim being pre
    sented in federal court was so lacking in justification that
    there was an error well understood and comprehended in
    existing law beyond any possibility for fairminded dis
    agreement.
    The reasons for this approach are familiar. “Federal
    habeas review of state convictions frustrates both the
    States’ sovereign power to punish offenders and their
    good-faith attempts to honor constitutional rights.”
    Calderon v. Thompson, 
    523 U. S. 538
    , 555–556 (1998)
    (internal quotation marks omitted). It “disturbs the
    State’s significant interest in repose for concluded litiga
    tion, denies society the right to punish some admitted
    offenders, and intrudes on state sovereignty to a degree
    matched by few exercises of federal judicial authority.”
    Reed, 
    489 U. S., at 282
     (KENNEDY, J., dissenting).
    Section 2254(d) is part of the basic structure of federal
    habeas jurisdiction, designed to confirm that state courts
    are the principal forum for asserting constitutional chal
    lenges to state convictions. Under the exhaustion re
    quirement, a habeas petitioner challenging a state convic
    tion must first attempt to present his claim in state court.
    
    28 U. S. C. §2254
    (b). If the state court rejects the claim on
    procedural grounds, the claim is barred in federal court
    14               HARRINGTON v. RICHTER
    Opinion of the Court
    unless one of the exceptions to the doctrine of Wainwright
    v. Sykes, 
    433 U. S. 72
    , 82–84 (1977), applies. And if the
    state court denies the claim on the merits, the claim is
    barred in federal court unless one of the exceptions to
    §2254(d) set out in §§2254(d)(1) and (2) applies. Section
    2254(d) thus complements the exhaustion requirement
    and the doctrine of procedural bar to ensure that state
    proceedings are the central process, not just a preliminary
    step for a later federal habeas proceeding, see id., at 90.
    Here, however, the Court of Appeals gave §2254(d) no
    operation or function in its reasoning. Its analysis illus
    trates a lack of deference to the state court’s determina
    tion and an improper intervention in state criminal proc
    esses, contrary to the purpose and mandate of AEDPA and
    to the now well-settled meaning and function of habeas
    corpus in the federal system.
    IV
    The conclusion of the Court of Appeals that Richter
    demonstrated an unreasonable application by the state
    court of the Strickland standard now must be discussed.
    To have been entitled to relief from the California Su
    preme Court, Richter had to show both that his counsel
    provided deficient assistance and that there was prejudice
    as a result.
    To establish deficient performance, a person challenging
    a conviction must show that “counsel’s representation fell
    below an objective standard of reasonableness.” 
    466 U. S., at 688
    . A court considering a claim of ineffective assis
    tance must apply a “strong presumption” that counsel’s
    representation was within the “wide range” of reasonable
    professional assistance. 
    Id., at 689
    . The challenger’s
    burden is to show “that counsel made errors so serious
    that counsel was not functioning as the ‘counsel’ guaran
    teed the defendant by the Sixth Amendment.” 
    Id., at 687
    .
    With respect to prejudice, a challenger must demon
    Cite as: 562 U. S. ____ (2011)           15
    Opinion of the Court
    strate “a reasonable probability that, but for counsel’s
    unprofessional errors, the result of the proceeding would
    have been different. A reasonable probability is a prob
    ability sufficient to undermine confidence in the outcome.”
    
    Id., at 694
    . It is not enough “to show that the errors had
    some conceivable effect on the outcome of the proceeding.”
    
    Id., at 693
    . Counsel’s errors must be “so serious as to
    deprive the defendant of a fair trial, a trial whose result is
    reliable.” 
    Id., at 687
    .
    “Surmounting Strickland’s high bar is never an easy
    task.” Padilla v. Kentucky, 559 U. S. ___, ___ (2010) (slip
    op., at 14). An ineffective-assistance claim can function as
    a way to escape rules of waiver and forfeiture and raise
    issues not presented at trial, and so the Strickland stan
    dard must be applied with scrupulous care, lest “intrusive
    post-trial inquiry” threaten the integrity of the very ad
    versary process the right to counsel is meant to serve.
    Strickland, 
    466 U. S., at
    689–690. Even under de novo
    review, the standard for judging counsel’s representation
    is a most deferential one. Unlike a later reviewing court,
    the attorney observed the relevant proceedings, knew of
    materials outside the record, and interacted with the
    client, with opposing counsel, and with the judge. It is “all
    too tempting” to “second-guess counsel’s assistance after
    conviction or adverse sentence.” 
    Id., at 689
    ; see also Bell
    v. Cone, 
    535 U. S. 685
    , 702 (2002); Lockhart v. Fretwell,
    
    506 U. S. 364
    , 372 (1993). The question is whether an
    attorney’s representation amounted to incompetence
    under “prevailing professional norms,” not whether it
    deviated from best practices or most common custom.
    Strickland, 
    466 U. S., at 690
    .
    Establishing that a state court’s application of Strick
    land was unreasonable under §2254(d) is all the more
    difficult.   The standards created by Strickland and
    §2254(d) are both “highly deferential,” id., at 689; Lindh v.
    Murphy, 
    521 U. S. 320
    , 333, n. 7 (1997), and when the two
    16                HARRINGTON v. RICHTER
    Opinion of the Court
    apply in tandem, review is “doubly” so, Knowles, 556 U. S.,
    at ___ (slip op., at 11). The Strickland standard is a gen
    eral one, so the range of reasonable applications is sub
    stantial. 556 U. S., at ___ (slip op., at 11). Federal habeas
    courts must guard against the danger of equating unrea
    sonableness under Strickland with unreasonableness
    under §2254(d). When §2254(d) applies, the question is
    not whether counsel’s actions were reasonable. The ques
    tion is whether there is any reasonable argument that
    counsel satisfied Strickland’s deferential standard.
    A
    With respect to defense counsel’s performance, the
    Court of Appeals held that because Richter’s attorney had
    not consulted forensic blood experts or introduced expert
    evidence, the California Supreme Court could not rea
    sonably have concluded counsel provided adequate repre
    sentation. This conclusion was erroneous.
    1
    The Court of Appeals first held that Richter’s attorney
    rendered constitutionally deficient service because he did
    not consult blood evidence experts in developing the basic
    strategy for Richter’s defense or offer their testimony as
    part of the principal case for the defense. Strickland,
    however, permits counsel to “make a reasonable decision
    that makes particular investigations unnecessary.” 
    466 U. S., at 691
    . It was at least arguable that a reasonable
    attorney could decide to forgo inquiry into the blood evi
    dence in the circumstances here.
    Criminal cases will arise where the only reasonable and
    available defense strategy requires consultation with
    experts or introduction of expert evidence, whether pre
    trial, at trial, or both. There are, however, “countless
    ways to provide effective assistance in any given case.
    Even the best criminal defense attorneys would not defend
    Cite as: 562 U. S. ____ (2011)           17
    Opinion of the Court
    a particular client in the same way.” 
    Id., at 689
    . Rare are
    the situations in which the “wide latitude counsel must
    have in making tactical decisions” will be limited to any
    one technique or approach. 
    Ibid.
     It can be assumed that
    in some cases counsel would be deemed ineffective for
    failing to consult or rely on experts, but even that formula
    tion is sufficiently general that state courts would have
    wide latitude in applying it. Here it would be well within
    the bounds of a reasonable judicial determination for the
    state court to conclude that defense counsel could follow a
    strategy that did not require the use of experts regarding
    the pool in the doorway to Johnson’s bedroom.
    From the perspective of Richter’s defense counsel when
    he was preparing Richter’s defense, there were any num
    ber of hypothetical experts—specialists in psychiatry,
    psychology, ballistics, fingerprints, tire treads, physiology,
    or numerous other disciplines and subdisciplines—whose
    insight might possibly have been useful. An attorney can
    avoid activities that appear “distractive from more impor
    tant duties.” Bobby v. Van Hook, 558 U. S. ___, ___ (2009)
    (per curiam) (slip op., at 8). Counsel was entitled to for
    mulate a strategy that was reasonable at the time and to
    balance limited resources in accord with effective trial
    tactics and strategies. See Knowles, supra, at ___ (slip op.,
    at 14–15); Rompilla v. Beard, 
    545 U. S. 374
    , 383 (2005);
    Wiggins v. Smith, 
    539 U. S. 510
    , 525 (2003); Strickland,
    
    466 U. S., at 699
    .
    In concluding otherwise the Court of Appeals failed to
    “reconstruct the circumstances of counsel’s challenged
    conduct” and “evaluate the conduct from counsel’s per
    spective at the time.” 
    Id., at 689
    . In its view Klein’s
    location was “the single most critical issue in the case”
    given the differing theories of the prosecution and the
    defense, and the source of the blood in the doorway was
    therefore of central concern. 
    578 F. 3d, at
    953–954. But it
    was far from a necessary conclusion that this was evident
    18               HARRINGTON v. RICHTER
    Opinion of the Court
    at the time of the trial. There were many factual differ
    ences between prosecution and defense versions of the
    events on the night of the shootings. It is only because
    forensic evidence has emerged concerning the source of the
    blood pool that the issue could with any plausibility be
    said to stand apart. Reliance on “the harsh light of hind
    sight” to cast doubt on a trial that took place now more
    than 15 years ago is precisely what Strickland and
    AEDPA seek to prevent. Cone, 
    535 U. S., at 702
    ; see also
    Lockhart, 
    506 U. S., at 372
    .
    Even if it had been apparent that expert blood testi
    mony could support Richter’s defense, it would be reason
    able to conclude that a competent attorney might elect not
    to use it. The Court of Appeals opinion for the en banc
    majority rests in large part on a hypothesis that reasona
    bly could have been rejected. The hypothesis is that with
    out jeopardizing Richter’s defense, an expert could have
    testified that the blood in Johnson’s doorway could not
    have come from Johnson and could have come from Klein,
    thus suggesting that Richter’s version of the shooting was
    correct and Johnson’s a fabrication. This theory overlooks
    the fact that concentrating on the blood pool carried its
    own serious risks. If serological analysis or other forensic
    evidence demonstrated that the blood came from Johnson
    alone, Richter’s story would be exposed as an invention.
    An attorney need not pursue an investigation that would
    be fruitless, much less one that might be harmful to the
    defense. Strickland, supra, at 691. Here Richter’s attor
    ney had reason to question the truth of his client’s ac
    count, given, for instance, Richter’s initial denial of
    involvement and the subsequent production of Johnson’s
    missing pistol.
    It would have been altogether reasonable to conclude
    that this concern justified the course Richter’s counsel
    pursued. Indeed, the Court of Appeals recognized this risk
    insofar as it pertained to the suggestion that counsel
    Cite as: 562 U. S. ____ (2011)           19
    Opinion of the Court
    should have had the blood evidence tested. 
    578 F. 3d, at 956, n. 9
    . But the court failed to recognize that making a
    central issue out of blood evidence would have increased
    the likelihood of the prosecution’s producing its own evi
    dence on the blood pool’s origins and composition; and
    once matters proceeded on this course, there was a serious
    risk that expert evidence could destroy Richter’s case.
    Even apart from this danger, there was the possibility
    that expert testimony could shift attention to esoteric
    matters of forensic science, distract the jury from whether
    Johnson was telling the truth, or transform the case into a
    battle of the experts. Accord, Bonin v. Calderon, 
    59 F. 3d 815
    , 836 (CA9 1995).
    True, it appears that defense counsel’s opening state
    ment itself inspired the prosecution to introduce expert
    forensic evidence. But the prosecution’s evidence may
    well have been weakened by the fact that it was assem
    bled late in the process; and in any event the prosecution’s
    response shows merely that the defense strategy did not
    work out as well as counsel had hoped, not that counsel
    was incompetent.
    To support a defense argument that the prosecution has
    not proved its case it sometimes is better to try to cast
    pervasive suspicion of doubt than to strive to prove a
    certainty that exonerates. All that happened here is that
    counsel pursued a course that conformed to the first op
    tion. If this case presented a de novo review of Strickland,
    the foregoing might well suffice to reject the claim of
    inadequate counsel, but that is an unnecessary step. The
    Court of Appeals must be reversed if there was a reason
    able justification for the state court’s decision. In light of
    the record here there was no basis to rule that the state
    court’s determination was unreasonable.
    The Court of Appeals erred in dismissing strategic
    considerations like these as an inaccurate account of
    counsel’s actual thinking. Although courts may not in
    20                HARRINGTON v. RICHTER
    Opinion of the Court
    dulge “post hoc rationalization” for counsel’s decisionmak
    ing that contradicts the available evidence of counsel’s
    actions, Wiggins, 
    539 U. S., at
    526–527, neither may they
    insist counsel confirm every aspect of the strategic basis
    for his or her actions. There is a “strong presumption”
    that counsel’s attention to certain issues to the exclusion
    of others reflects trial tactics rather than “sheer neglect.”
    Yarborough v. Gentry, 
    540 U. S. 1
    , 8 (2003) (per curiam).
    After an adverse verdict at trial even the most experienced
    counsel may find it difficult to resist asking whether a
    different strategy might have been better, and, in the
    course of that reflection, to magnify their own responsibil
    ity for an unfavorable outcome. Strickland, however, calls
    for an inquiry into the objective reasonableness of coun
    sel’s performance, not counsel’s subjective state of mind.
    
    466 U. S., at 688
    .
    2
    The Court of Appeals also found that Richter’s attorney
    was constitutionally deficient because he had not expected
    the prosecution to offer expert testimony and therefore
    was unable to offer expert testimony of his own in re
    sponse.
    The Court of Appeals erred in suggesting counsel had
    to be prepared for “any contingency,” 
    578 F. 3d, at 946
    (internal quotation marks omitted).        Strickland does
    not guarantee perfect representation, only a “ ‘reasonably
    competent attorney.’ ” 
    466 U. S., at 687
     (quoting McMann
    v. Richardson, 
    397 U. S. 759
    , 770 (1970)); see also Gentry,
    
    supra, at 7
    . Representation is constitutionally ineffective
    only if it “so undermined the proper functioning of the
    adversarial process” that the defendant was denied a fair
    trial. Strickland, 
    supra, at 686
    . Just as there is no expec
    tation that competent counsel will be a flawless strategist
    or tactician, an attorney may not be faulted for a reason
    able miscalculation or lack of foresight or for failing to
    Cite as: 562 U. S. ____ (2011)           21
    Opinion of the Court
    prepare for what appear to be remote possibilities.
    Here, Richter’s attorney was mistaken in thinking the
    prosecution would not present forensic testimony. But the
    prosecution itself did not expect to make that presenta-
    tion and had made no preparations for doing so on the eve
    of trial. For this reason alone, it is at least debatable
    whether counsel’s error was so fundamental as to call the
    fairness of the trial into doubt.
    Even if counsel should have foreseen that the prosecu
    tion would offer expert evidence, Richter would still need
    to show it was indisputable that Strickland required his
    attorney to act upon that knowledge. Attempting to estab
    lish this, the Court of Appeals held that defense counsel
    should have offered expert testimony to rebut the evidence
    from the prosecution. But Strickland does not enact New
    ton’s third law for the presentation of evidence, requiring
    for every prosecution expert an equal and opposite expert
    from the defense.
    In many instances cross-examination will be sufficient
    to expose defects in an expert’s presentation. When de
    fense counsel does not have a solid case, the best strategy
    can be to say that there is too much doubt about the
    State’s theory for a jury to convict. And while in some
    instances “even an isolated error” can support an ineffec
    tive-assistance claim if it is “sufficiently egregious and
    prejudicial,” Murray v. Carrier, 
    477 U. S. 478
    , 496 (1986),
    it is difficult to establish ineffective assistance when coun
    sel’s overall performance indicates active and capable
    advocacy. Here Richter’s attorney represented him with
    vigor and conducted a skillful cross-examination. As
    noted, defense counsel elicited concessions from the State’s
    experts and was able to draw attention to weaknesses in
    their conclusions stemming from the fact that their analy
    ses were conducted long after investigators had left the
    crime scene. For all of these reasons, it would have been
    reasonable to find that Richter had not shown his attorney
    22               HARRINGTON v. RICHTER
    Opinion of the Court
    was deficient under Strickland.
    B
    The Court of Appeals further concluded that Richter had
    established prejudice under Strickland given the expert
    evidence his attorney could have introduced. It held that
    the California Supreme Court would have been unreason
    able in concluding otherwise. This too was error.
    In assessing prejudice under Strickland, the question is
    not whether a court can be certain counsel’s performance
    had no effect on the outcome or whether it is possible a
    reasonable doubt might have been established if counsel
    acted differently. See Wong v. Belmontes, 558 U. S. ___,
    ___ (2009) (per curiam) (slip op., at 13); Strickland, 
    466 U. S., at 693
    . Instead, Strickland asks whether it is “rea
    sonably likely” the result would have been different. 
    Id., at 696
    . This does not require a showing that counsel’s
    actions “more likely than not altered the outcome,” but the
    difference between Strickland’s prejudice standard and a
    more-probable-than-not standard is slight and matters
    “only in the rarest case.” 
    Id., at 693, 697
    . The likelihood
    of a different result must be substantial, not just conceiv
    able. 
    Id., at 693
    .
    It would not have been unreasonable for the California
    Supreme Court to conclude Richter’s evidence of prejudice
    fell short of this standard. His expert serology evidence
    established nothing more than a theoretical possibility
    that, in addition to blood of Johnson’s type, Klein’s blood
    may also have been present in a blood sample taken near
    the bedroom doorway pool. At trial, defense counsel ex
    tracted a concession along these lines from the prosecu
    tion’s expert. The pathology expert’s claim about the size
    of the blood pool could be taken to suggest only that the
    wounded and hysterical Johnson erred in his assessment
    of time or that he bled more profusely than estimated.
    And the analysis of the purported blood pattern expert
    Cite as: 562 U. S. ____ (2011)          23
    Opinion of the Court
    indicated no more than that Johnson was not standing up
    when the blood pool formed.
    It was also reasonable to find Richter had not estab
    lished prejudice given that he offered no evidence directly
    challenging other conclusions reached by the prosecution’s
    experts. For example, there was no dispute that the blood
    sample taken near the doorway pool matched Johnson’s
    blood type. The California Supreme Court reasonably
    could have concluded that testimony about patterns that
    form when blood drips to the floor or about the rate at
    which Johnson was bleeding did not undermine the re
    sults of chemical tests indicating blood type. Nor did
    Richter provide any direct refutation of the State’s expert
    testimony describing how blood spatter near the couch
    suggested a shooting in the living room and how the blood
    patterns on Klein’s face were inconsistent with Richter’s
    theory that Klein had been killed in the bedroom doorway
    and moved to the couch.
    There was, furthermore, sufficient conventional circum
    stantial evidence pointing to Richter’s guilt. It included
    the gun safe and ammunition found at his home; his flight
    from the crime scene; his disposal of the .32-caliber gun
    and of Johnson’s pistol; his shifting story concerning his
    involvement; the disappearance prior to the arrival of the
    law enforcement officers of the .22-caliber weapon that
    killed Klein; the improbability of Branscombe’s not being
    wounded in the shootout that resulted in a combined four
    bullet wounds to Johnson and Klein; and the difficulties
    the intoxicated and twice-shot Johnson would have had in
    carrying the body of a dying man from bedroom doorway
    to living room couch, not to mention the lack of any obvi
    ous reason for him to do so. There was ample basis for the
    California Supreme Court to think any real possibility of
    Richter’s being acquitted was eclipsed by the remaining
    evidence pointing to guilt.
    24               HARRINGTON v. RICHTER
    Opinion of the Court
    *    *     *
    The California Supreme Court’s decision on the merits
    of Richter’s Strickland claim required more deference than
    it received. Richter was not entitled to the relief ordered
    by the Court of Appeals. The judgment is reversed, and
    the case is remanded for further proceedings consistent
    with this opinion.
    It is so ordered.

    JOSHUA RICHTER
    ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
    APPEALS FOR THE NINTH CIRCUIT
    [January 19, 2011]
    JUSTICE GINSBURG, concurring in the judgment.
    In failing even to consult blood experts in preparation
    for the murder trial, Richter’s counsel, I agree with the
    Court of Appeals, “was not functioning as the ‘counsel’
    guaranteed the defendant by the Sixth Amendment.”
    Strickland v. Washington, 
    466 U. S. 668
    , 687 (1984). The
    strong force of the prosecution’s case, however, was not
    significantly reduced by the affidavits offered in support of
    Richter’s habeas petition. I would therefore not rank
    counsel’s lapse “so serious as to deprive [Richter] of a fair
    trial, a trial whose result is reliable.” 
    Ibid.
     For that rea
    son, I concur in the Court’s judgment.
