OPINION OF THE COURT
In 1999, a jury found Wali Palmer guilty of multiple crimes related to a 1998 shooting death in an Atlantic City bar. After he unsuccessfully appealed his conviction, Palmer sought post-conviction relief in the New Jersey state courts, asserting that his attorney had been constitutionally ineffective. The New Jersey courts denied Palmer’s petition for post-conviction relief, and Palmer thereafter filed a petition for a writ of habeas corpus in the New Jersey District Court pursuant to 28 U.S.C. § 2254. The District Court did not convene an evidentiary hearing and dismissed Palmer’s petition.
We granted Palmer’s application for a certificate of appealability as to three issues: (1) whether Palmer’s trial attorney rendered ineffective assistance of counsel by failing to advise Palmer of his right to testify at trial and at a suppression hearing, (2) whether his attorney was ineffective in failing to inform Palmer that the choice of whether to testify was ultimately Palmer’s to make, and (3) whether the District Court should have held an evidentiary hearing to resolve these claims. We conclude that Palmer failed to make a prima facie showing of the prejudice element of his ineffective assistance of counsel claims and that the District Court did not abuse its discretion in declining to convene an evidentiary hearing to resolve Palmer’s claims.
I.
In March 1998, Palmer was attacked by a group of young men at a bar in Atlantic City, New Jersey. During the scuffle, Palmer pulled out a nine-millimeter automatic handgun and fired two wild shots. One shot hit the leg of one of his attackers, Shawn Brantley; the other shot hit and killed Palmer’s cousin, Junior (Jerry) Cooper, who had been trying to help Palmer. Palmer attempted to assist his cousin, but when he realized that his cousin was not moving, Palmer fled the scene on a bicycle. Police responded to the shooting, gathered a description of Palmer from the wounded Brantley, and arrested Palmer a few blocks from the bar.
*389
After his arrest, Palmer gave several incriminating statements to the police. He later moved, pursuant to
Miranda v. Arizona,
Trial was conducted between June 15 and June 23, 1999. After the State rested, Palmer and his attorney, Williams Harris, Esq., engaged in two colloquies on the record, which became relevant during the state post-conviction proceedings. First, once the State had rested, the court and counsel discussed whether all of the State’s exhibits had been admitted into evidence, after which the following colloquy took place:
COURT: If there’s an oversight you suddenly discover, we can deal with that. We’ll take a recess to afford Mr. Harris to consult with his client.
HARRIS: Thank you judge.
(Recess)
(After Recess)
(Whereupon the following took place out of the presence of the jury)
HARRIS: We’re going to rest, judge.
COURT: Okay.
(App.200.)
The next day, before the court charged the jury, the following exchange between the court, defense counsel, and Palmer took place:
HARRIS: Can I have a moment off the record?
COURT: Sure.
(Off Record)
HARRIS: Your honor, I’d like to have you read the defendant’s election not to testify charge to my client so that we can make a decision on that.
COURT: I’ll be glad to do that.
HARRIS: Thank you.
COURT: Mr. Palmer, this is the charge that I give to the jury, if you wish, and it reads as follows. It’s the constitutional right of a defendant to remain silent. I charge you that you are not to consider for any purpose or any manner in arriving at your verdict the fact that the defendant did not testify, nor should that fact enter into your deliberations or discussions in any manner or at anytime. The defendant is entitled to have the jury consider all the evidence, and he is entitled to the presumption of innocence even if he does not testify as a witness.
HARRIS: Could I have one second, Judge?
(Discussion off the record. Counsel conferring with Defendant.)
HARRIS: We’re going to ask that you do read it to the jury.
COURT: Mr. Palmer, you wish that given?
PALMER: Yes.
COURT: Thank you, I will.
(App.207.)
The jury was charged and, after deliberating, it found Palmer guilty of aggravated manslaughter, aggravated assault, possession of a weapon for an unlawful purpose, and unlawful possession of a weapon. Palmer was subsequently given a sentence of twenty-two years for the manslaughter conviction, a consecutive sentence of eight years for the assault conviction, and a concurrent sentence of five years for the weapons convictions. Palmer appealed the convictions and sentence, challenging, among other things, the admissibility of *390 the non-suppressed statements and the severity of his sentence. The New Jersey Appellate Division affirmed.
After his direct appeal failed, Palmer filed a petition for post-conviction relief. In his petition, Palmer argued that Harris had been constitutionally ineffective for, among other things, failing to advise him of his right to testify on his own behalf. Palmer submitted with his petition a sworn affidavit that stated:
• That, my former trial attorney Mr. Williams Harris had never informed me about my right to testify prior to trial, or that the decision not to testify was my decision to make and not Mr. Harris’s.
• That, prior to going into the courtroom, Mr. Harris had c[o]me down to the bullpen or holding cell area in the courthouse, and I had asked Mr. Harris when he was going to put me on the stand to tell my side of what happened, and Mr. Harris had told me that he was not going to put me on the stand or testify or call me as a witness.
• That, during my trial, the Judge began reading something about me choosing not to testify, and saying that I chose not to testify, at which point I attempted to respond by telling Mr. Harris that he’s making it sound like I don’t want to tell my side, and Mr. Harris tapped me to hold up, and asked the judge for a second to speak to me.
• That, Mr. Harris then told me that, because he was not using me as a witness that the judge has to read those things to the jury so that they can’t hold anything against me or bring up anything about me not taking the stand, and that Mr. Harris at that point still did not explain to me that I had a right to testify or that the choice of whether to testify was solely mine[ ] to make and not his.
• That, prior to Mr. Harris telling me that he was not going to put me on the stand, I was under the impression that I would get to tell my side of what happened.
• That, I would have taken the stand to testify on my own behalf to explain my side of what really happened if I was allowed to do so.
(App.87a-b.) In sum, Palmer argued that his trial counsel never took the time to explain to him that the choice of whether or not he would testify was for Palmer, not Harris, to make. Palmer also argued that the trial record was inconclusive as to whether Harris ever conveyed this information and that the jury charge colloquy revealed little about whether Palmer understood his right to testify. Accordingly, Palmer requested an evidentiary hearing to subpoena Harris and develop the factual record. Notably, Palmer did not set forth the facts to which he would have testified had he taken the stand at his trial.
The post-conviction relief (“PCR”) court rejected Palmer’s petition without granting an evidentiary hearing. Emphasizing the colloquy between the court and defense counsel at the close of the State’s case, the PCR court found that Palmer and his attorney had been afforded the opportunity for Harris to counsel Palmer as to whether or not to testify. Additionally, relying upon the colloquy between the court, defense counsel, and Palmer just prior to the jury charge, the PCR court found that Palmer understood that he had a choice regarding whether to testify:
Then we get to what transpires with respect to the charge. And Mr. Harris says, “Your Honor, I’d like to have you read the defendant’s election not to testify charge to my client so that we can make a decision on that.” So we’re talking about defendant’s election not to testify, the defendant’s right not to testi *391 fy. Implicit in that is a right to testify. And the charge that was read to him was this: “The defendant in this case chose not to be a witness.” First line in the charge. If you choose not to be a witness, you can also choose to be a witness. So by the charge itself, which was read to the defendant, the defendant was told by me with respect to his choices. He chose not to be; implicit in that is a choosing to be. And the last sentence of the charge ... reads that, “The defendant is entitled to have the jury consider all of the evidence and he is entitled to the presumption of innocence even if he does not testify as a witness.” Implicit in that as well is the fact that he can testify as a witness. To say that he was never told that he could be a witness, I think is belied by the transcript in this particular case.
(App.47-49.) The Appellate Division upheld this decision “for substantially the same reasons,” but also took note of the “pauses in the proceedings for discussions between trial counsel and defendant,” which “belie[ ] defendant’s contentions that he was unaware of his right to testify and that he had no discussions with his attorney about that right.” (App.32.) The New Jersey Supreme Court denied certification.
Having exhausted his state court remedies, Palmer filed a habeas petition pursuant to 28 U.S.C. § 2254 in the District Court. In his petition, Palmer claimed that his trial counsel had been constitutionally ineffective; he likewise asserted a host of additional issues not relevant to this appeal. The District Court denied the entirety of his petition. With regard to the issue of Palmer’s right to testify, the District Court quoted the language of the PCR court, endorsing the portion of that opinion that found that Palmer understood his right to testify, and rejected the petition on the grounds that “the New Jersey Courts’ adjudication of the claims did not result in a decision that was contrary to, or involved an unreasonable application of Strickland or other Supreme .Court holdings.” (App.20.) The Court declined to hold an evidentiary hearing and declined to issue a certificate of appealability.
Finally, Palmer appealed to this Court. We granted a certificate of appealability with respect to Palmer’s claims that his trial counsel rendered ineffective assistance of counsel for “(1) failing to advise Appellant of his right to testify at trial and at his suppression hearing and (2) failing to inform Appellant that the choice whether to testify was ultimately his to make.” (App.23.) We also stated that the parties “shall address whether the District Court should have held an evidentiary hearing to resolve these claims.” (App.23.)
II.
The District Court exercised jurisdiction pursuant to 28 U.S.C. § 2254. We have jurisdiction over Palmer’s appeal under 28 U.S.C. §§ 1291 and 2253.
The Anti-Terrorism and Effective Death Penalty Act of 1996 (“AEDPA”)
1
“requires federal courts collaterally reviewing state proceedings to afford consid
*392
erable deference to state courts’ legal and factual determinations.”
Lambert v. Blackwell,
By its own terms, § 2254(d) only applies to claims already “adjudicated on the merits in State court proceedings.” Thus, if a properly preserved claim was not addressed by the state court on the merits, the deferential standards of AED-PA do not apply.
See Appel v. Horn,
III.
A.
We address at the outset whether the District Court abused its discretion when it denied Palmer’s habeas petition without first convening an evidentiary hearing. We conclude that because Palmer’s petition does not contain sufficient “factual allegations, which, if true, would entitle the applicant to federal habeas relief,” the District Court did not abuse its discretion in declining Palmer’s request for an evidentiary hearing.
Schriro v. Landrigan,
1. The Decision Whether to Hold an Evidentiary Hearing is Subject to the Discretion of the District Court
“Prior to AEDPA, new evidentiary hearings [in habeas cases] were
required
in several circumstances.”
Campbell v. Vaughn,
*393
“In cases where an applicant for federal habeas relief is not barred from obtaining an evidentiary hearing by 28 U.S.C. § 2254(e)(2), the decision to grant such a hearing rests in the discretion of the district court.”
Schriro,
First, in determining whether or not to hold an evidentiary hearing, courts should “consider whether such a hearing could enable an applicant to prove the petition’s factual allegations, which, if true, would entitle the applicant to federal habeas relief.”
Schriro,
Second, “if the record refutes the applicant’s factual allegations or otherwise precludes habeas relief, a district court is not required to hold an evidentiary hearing.”
Schriro,
With these twin considerations in mind, we turn to Palmer’s petition to determine whether the District Court abused its dis *394 cretion when it dismissed the petition without first convening an evidentiary hearing.
2. Palmer’s Inadequate Allegations of Prejudice
Because we find that the factual allegations underlying Palmer’s contention that his trial counsel was constitutionally ineffective are insufficient to show that he is “entitle[d] ... to federal habeas relief,”
id.
at 474,
“The
Strickland [v. Washington,
Palmer’s petition comes up short because it fails to make an adequate showing of prejudice.
See id.
at 697,
Palmer’s stated desire to tell his side of the story and his conclusory invocation of the words “self-defense” are not sufficient to show “that the decision reached would reasonably likely have been different absent the errors.”
Strickland,
Zettlemoyer
is on point. In that case, the petitioner contended that an evidentiary hearing was necessary to develop the facts of his ineffective assistance claim, in which he asserted that his attorney had failed to call witnesses who would have provided unspecified testimony related to his diminished-capacity defense.
See Zettlemoyer,
*396
In
Owens v. United States,
On the other hand, the mere assertion of self-defense is not sufficient to raise a plausible showing of prejudice sufficient to warrant an evidentiary hearing. If so, every defendant charged with homicide would make such an assertion. In
Owens,
the court particularized the needed showing when it stated that a defendant who was not informed by counsel or the court of his right to testify and who “would have offered
genuinely exculpatory
testimony” would have been prejudiced by the failure to have been informed of his right to testify.
Owens,
In New Jersey, the assertion of self-defense “requires a jury (1) to discern whether the defendant had a subjective belief at the time that deadly force was necessary and then (2) to determine whether that subjective belief was objeetively reasonable.”
State v. Jenewicz,
3. There Is No Presumption of Prejudice in Rightr-to-Testify Cases
Conceding that “the record is silent about the nature of Palmer’s probable testimony,” (Appellant’s Br. 22), Palmer contends that he should be relieved from making any showing as to
Strickland’s
prejudice criterion. Although his argument on this point is somewhat muddled, Palmer appears to suggest that when counsel fails to properly advise a client concerning the right to testify, such defective performance by counsel is not susceptible to analysis under
Strickland’s
two-prong standard, but is instead a “structural defect” in the entire trial process that requires automatic reversal, irrespective of prejudice.
See Neder v. United States,
As an initial matter, Palmer is certainly correct to note that “[t]he Supreme Court has distinguished between two types of constitutional error that occur at both trial and sentencing: ‘trial errors,’ which are subject to constitutional harmless error analysis, and ‘structural defects,’ which require automatic reversal or vacatur.”
United States v. Stevens,
We are not persuaded by Palmer’s argument that his attorney’s alleged failure to advise him of his right to testify falls within this very limited category of errors that are
per se
reversible. First, every authority we are aware of that has addressed the matter of counsel’s failure to advise a client of the right to testify has done so under
Strickland’s
two-prong framework, which requires the petitioner to “show that [the deficient conduct] actually had an adverse effect on the defense.”

Strickland,
Moreover,
Strickland
itself cannot be read to carve out a prejudice exception for right-to-testify cases. By its terms,
Strickland
applies to all manner of ineffective assistance of counsel claims.
See Strickland,
Finally, Palmer’s claim that his attorney failed to advise him of his right to testify in his own defense is not the sort of structural defect for which the automatic reversal rule is reserved. “[Mjost constitutional errors” are of the trial type,
Fulminante,
By contrast, a defendant’s testimony (or lack thereof) occurs “during the presentation of the case to the jury” and “may therefore be quantitatively assessed in the context of other evidence presented____”
Fulminante,
Of course, the defendant’s own testimony is very likely to be highly important— as we noted above, “the most important witness for the defense in many criminal cases is the defendant himself,”
Rock,
In sum, Palmer was required to prove prejudice in order to prevail on his ineffective assistance claim,
id.,
and factual allegations of prejudice were thus an essential component to a
prima facie
showing of his entitlement to habeas relief. Because Palmer’s petition contains insufficient factual allegations to demonstrate his entitlement to relief, we conclude that the District Court did not abuse its discretion in declining to convene an evidentiary hearing.
See, e.g., Campbell,
B.
Our determination that Palmer’s petition fails to present a
prima facie
showing of ineffective assistance of counsel and our decision that the District Court did not abuse its discretion when it declined to
*400
hold an evidentiary hearing are sufficient to resolve the remaining question raised in this appeal — namely, whether Palmer’s attorney rendered ineffective assistance of counsel by failing to advise Palmer of his right to testify and by failing to inform Palmer that the decision was Palmer’s to make. In order to prevail on his claim that his attorney rendered constitutionally deficient assistance, Palmer was required to establish prejudice by “showpng] that [the deficient conduct] actually had an adverse effect on the defense.”
Strickland,
We recognize that because the state courts did not decide the prejudice issue on the merits, AEDPA’s deferential standards do not apply to our resolution of the prejudice question.
See Wiggins v. Smith,
IV.
For the foregoing reasons, we will affirm the judgment of the District Court.
Notes
. The relevant provisions of AEDPA provide: (d) 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 involved an unreasonable application of, clearly established Federal law, as determined by the Supreme Court of the United States; or (2) resulted in a decision that was based on an unreasonable determination of the facts in light of the evidence presented in the State court proceeding.
28 U.S.C. § 2254(d).
. Under section 2254(e)(2),
[i]f the applicant has failed to develop the factual basis of a claim in State court proceedings, the court shall not hold an evidentiary hearing on the claim unless the applicant shows that—
(A) the claim relies on—
(i) a new rule of constitutional law, made retroactive to cases on collateral review by the Supreme Court, that was previously unavailable; or
(ii) a factual predicate that could not have been previously discovered through the exercise of due diligence; and
*393 (B) the facts underlying the claim would be sufficient to establish by clear and convincing evidence that but for constitutional error, no reasonable factfinder would have found the applicant guilty of the underlying offense.
28 U.S.C. § 2254(e)(2).
. The Supreme Court has not held, and we do not suggest, that a court is precluded from considering additional factors in determining the appropriateness of an evidentiary hearing.
. As an initial matter, we note that Palmer was diligent in his effort to develop the factual basis of his ineffective assistance claim in the state PCR court, in that he submitted an affidavit and requested that the state court convene a hearing on his claim.
See Williams, 529 U.S.
at 430,
. Palmer, as the very witness whose testimony was not presented at trial, would certainly have been capable of outlining in his habeas petition the contours of the testimony he would have given. This is not, in other words, a case in which an evidentiary hearing *396 was needed in order to unearth facts unknown to the petitioner.
. Of course, in the collateral review context, even trial-type errors are not examined under the harmless-beyond-a-reasonable-doubt standard employed on direct review, but are instead reviewed under
Brecht’s
more deferential standard.
See Brecht,
. In
Campbell v. Vaughn,
we declined to take a position on this issue, as our threshold determination that the attorney’s performance was not deficient rendered the point moot.
