Justice Stewart
delivered the opinion of the Court.
In this case a Kentucky criminal trial judge refused a defendant’s request to give the following jury instruction: “The [defendant] is not compelled to testify and the fact that he does not cannot be used as an inference of guilt and should not prejudice him in any way.” The Supreme Court of Kentucky found no error. We granted certiorari to consider the petitioner’s contention that a defendant, upon request, has a right to such an instruction under the Fifth and Fourteenth Amendments of the Constitution. 449 U. S. 819.

A
In the early morning of December 22, 1978, Officer Deborah Ellison of the Hopkinsville, Kentucky, Police Department, on routine patrol in downtown Hopkinsville, noticed something in the alley between Young’s Hardware Store and Edna’s Furniture Store. She backed her car up, flashed her spotlight down the alley, and saw two men stooped alongside one of the buildings. The men ran off. Officer Ellison drove her squad car down the alley and found a hole in the side of Young’s Hardware Store. She radioed Officer Leroy Davis, whom she knew to be in the area, informing him that two men had fled from the alley.
Soon after receiving Ellison’s call, Officer Davis saw two men run across a street near where he had been patrolling. The two ran in opposite directions, and Davis proceeded after one of them. Following a chase, during which he twice lost sight of the man he was pursuing, Davis was finally able to stop him. The man was later identified as the petitioner, Lonnie Joe Carter. During the course of the chase, Davis saw the petitioner drop two objects: a gym bag and a radio tuned to a police band. When apprehended, the petitioner was wearing gloves but no jacket. While Davis was pursuing the petitioner, Officer Ellison inspected the alley near the hole in the building wall. She found two jackets, along with some merchandise that had apparently been removed from the hardware store.
After arresting the petitioner, Davis brought him to Officer Ellison to see if she could identify him as one of the men she had seen in the alley. Ellison noted that he was of similar height and weight to one of the men in the alley, and that he wore similar clothing, but because it had been too dark to get a good view of the men’s faces, she could not make a more positive identification. The petitioner was then taken to police headquarters.

The petitioner was subsequently indicted for third-degree burglary of Young’s Hardware Store. The indictment also charged him with being a persistent felony offender, in violation of Ky. Rev. Stat. § 532.080 (Supp. 1980), on the basis of previous felony convictions. At the trial, the voir dire examination of prospective jurors was conducted solely by the judge. The prosecutor’s opening statement recounted the evidence expected to be introduced against the petitioner. The opening statement of defense counsel began as follows:
“Let me tell you a little bit about how this system works. If you listened to Mr. Ruff [the prosecutor] you are probably ready to put Lonnie Joe in the penitentiary. He read you a bill, a true bill that was issued by the Grand Jury. Now, the Grand Jury is a group of people that meet back here in a room and the defendant is not able or not allowed to present any of his testimony before this group of people. The only thing that the Grand Jury hears is the prosecution’s proof and I would say approximately what Mr. Ruff has said to you. I suppose that most of you would issue a true bill if Mr. Ruff told you what he has just told you and you didn’t have a chance to hear what the defendant had to say for himself.
“Now, that is just completely contrary to our system of law. A man, as the Judge has already told you, . . . is innocent until . . . proved guilty . . . .”
The prosecution rested after calling Officers Ellison, Davis, another officer, and the owner of Young’s Hardware Store. The trial judge then held a conference, outside of the hearing of the jury, to determine whether the petitioner would testify, and whether the prosecutor would be permitted to impeach the petitioner with his prior felony convictions. Defense counsel stated:
“Judge, I think possibly the only reservation Mr. Carter might have about testifying would be his impeachment by the use of these previous offenses that he is aware of and has told me about. I would like to explain to him in front of you what this all means.”
Counsel then explained to the petitioner that if he testified the Commonwealth could “use the fact that you have several offenses on your record . . . [to] impeach your . . . propensity to tell the truth . . . .” Counsel added that in his experience this was “a heavy thing; it is very serious, and I think juries take it very seriously . . . .” The judge indicated that under Kentucky law he had “discretionary control” over the use of prior felony convictions for impeachment, and cautioned the prosecutor that he might be inviting a reversal if he introduced more than three prior felony convictions, strongly suggesting that the prosecutor rely on the most recent convictions only. The judge then addressed the petitioner: •
“THE COURT: ... You can sit there and say nothing and it cannot be mentioned if you don’t testify but if you do these other convictions can be shown to indicate to the jury that maybe you are not telling the truth.
“THE COURT: . . . [Y]ou talk to Mr. Rogers [defense counsel] and then tell us what you want to do.
“THE COURT: Now, Lonnie, you have come back after a private conference with your lawyer, Mr. Rogers[,] and you have told me you have decided not to take the stand?
“LONNIE JOE CARTER: Yes, Sir.”
Upon returning to open court, the petitioner’s counsel advised the court that there would be no testimony introduced on behalf of the defense. He then requested that the following instruction be given to the jury:
“The [defendant] is not compelled to testify and the fact that he does not cannot be used as an inference of guilt and should not prejudice him in any way.”
The trial court refused the request.
The prosecutor began his summation by stating that he intended to review the evidence “that we were privileged to hear,” and cautioned the jury to “[c]onsider only what you have heard up here as evidence in this case and not something that you might speculate happened or could have happened . . . .” After mentioning admissions that the petitioner had allegedly made at police headquarters, the prosecutor argued:
“Now that is not controverted whatsoever. It is not controverted that Lonnie Joe is the man that Miss Ellison saw here. It is not controverted that Lonnie Joe is the man that Davis caught up here (again pointing to blackboard sketch). It is not controverted that Lonnie Joe had that bag (pointing to bag on reporter’s desk) and that radio (pointing to radio) with him. It is not controverted that both of those jackets belong to Lonnie Joe. At least, that is what he told the police department. But, at any rate, that is all we have to go on . . . .”
The prosecutor continued that if there was a reasonable explanation why the petitioner ran when he saw the police, it was “not in the record.”
The jury found the petitioner guilty, recommending a sentence of two years. The recidivist phase of the trial followed. The prosecutor presented evidence of the previous felony convictions that had been listed in the indictment. The defense presented no evidence, and the jury found the petitioner guilty as a persistent offender, sentencing him to the maximum term of 20 years in prison.
Upon appeal, the Kentucky Supreme Court rejected the argument that the Fifth and Fourteenth Amendments to the United States Constitution require that a criminal trial judge give the jury an instruction such as was requested here. In concluding that the trial judge did not commit error by refusing to give the requested instruction, the court pointed to Ky. Rev. Stat. § 421.225 (Supp. 1980), which provides:
“In any criminal or penal prosecution the defendant, on his own request, shall be allowed to testify in his own behalf, but his. failure to do so shall not be commented upon or create any presumption against him.”
Holding that the jury instruction requested by counsel would have required the trial judge to “comment upon” the defendant’s failure to testify, the court cited its previous decision in Green v. Commonwealth, 488 S. W. 2d 339, as controlling.
II
A
The constitutional question presented by this case is one the Court has specifically anticipated and reserved, first in Griffin v. California, 380 U. S. 609, 615, n. 6, and more recently in Lakeside v. Oregon, 435 U. S. 333, 337. But, as a question of federal statutory law, it was resolved by a unanimous Court over 40 years ago in Bruno v. United States, 308 U. S. 287. The petitioner in Bruno was a defendant in a federal criminal trial who had requested a jury instruction similar to the one requested by the petitioner in this case. The Court, addressing the question whether Bruno “had the indefeasible right” that his proffered instruction be given to the jury, decided that a federal statute, which prohibits the creation of any presumption from a defendant’s failure to testify, required that the “substance of the denied request should have been granted . . . Id., at 294.
The Griffin case came here shortly after the Court had held that the Fifth Amendment command that no person “shall be compelled in any criminal case to be a witness against himself” is applicable against the States through the Fourteenth Amendment. Malloy v. Hogan, 378 U. S. I. In Griffin, the Court considered the question whether it is a violation of the Fifth and Fourteenth Amendments to invite a jury in a state criminal trial to draw an unfavorable inference from a defendant’s failure to testify. The trial judge had there instructed the jury that “a defendant has a constitutional right not to testify,” and that the defendant’s exercise of that right “does not create a presumption of guilt nor by itself warrant an inference of guilt” nor “relieve the prosecution of any of its burden of proof.” But the instruction additionally permitted the jury to “take that failure into consideration as tending to indicate the truth of [the State’s] evidence and as indicating that among the inferences that may be reasonably drawn therefrom those unfavorable to the defendant are the more probable.” 380 U. S., at 610.
This Court set aside Griffin’s conviction because “the Fifth Amendment . . . forbids either comment by the prosecution on the accused’s silence or instructions by the court that such silence is evidence of guilt.” Id., at 615. It condemned adverse comment on a defendant’s failure to testify as reminiscent of the “ ‘inquisitorial system of criminal justice/ ” id., at 614, quoting Murphy v. Waterfront Comm’n, 378 U. S. 52, 55, and concluded that such comment effected a court-imposed penalty upon the defendant that was unacceptable because “[i]t cuts down on the privilege by making its assertion costly.” 380 U. S., at 614.
The Court returned to a consideration of the Fifth Amendment and jury instructions in Lakeside v. Oregon, 435 U. S, 333, where the question was whether the giving of a “no-inference” instruction over defense objection violates the Constitution. Despite trial counsel’s complaint that his strategy was to avoid any mention of his client’s failure to testify, a no-inference instruction was given by the trial judge. The petitioner contended that when a trial judge in any way draws the jury’s attention to a defendant’s failure to testify, unless the defendant acquiesces, the court invades the defendant’s privilege against compulsory self-incrimination. This argument was rejected.
The Lakeside Court reasoned that the Fifth and Fourteenth Amendments bar only adverse comment on a defendant’s failure to testify, and that “a judge’s instruction that the jury must draw no adverse inferences of any kind from the defendant’s exercise of his privilege not to testify is 'comment’ of an entirely different order.” Id., at 339. The purpose of such an instruction, the Court stated, “is to remove from the jury’s deliberations any influence of unspoken adverse inferences,” and “cannot provide the pressure on a defendant found impermissible in Griffin.” Ibid.
The Court observed in Lakeside that the petitioner’s argument there rested on “two very doubtful assumptions:”
“First, that the jurors have not noticed that the defendant did not testify and will not, therefore, draw adverse inferences on their own. Second, that the jurors will totally disregard the instruction, and affirmatively give weight to what they have been told not to consider at all. Federal constitutional law cannot rest on speculative assumptions so dubious as these.” Id., at 340 (footnote omitted).
Finally, the Court stressed that “[t]he very purpose” of a jury instruction is to direct the jurors’ attention to important legal concepts “that must not be misunderstood, such as reasonable doubt and burden of proof,” and emphasized that instruction “in the meaning of the privilege against compulsory self-incrimination is no different.” Ibid.
B
The inclusion of the privilege against compulsory self-incrimination in the Fifth Amendment
“reflects many of our fundamental values and most noble aspirations: our unwillingness to subject those suspected of crime to the cruel trilemma of self-accusation, perjury or contempt; . . . our fear that self-incriminating statements will be elicited by inhumane treatment and abuses; our sense of fair play which dictates ‘a fair state-individual balance by requiring the government ... , in its contest with the individual to shoulder the entire load,’ . . . ; our distrust of self-deprecatory statements; and our realization that the privilege, while sometimes 'a shelter to the guilty/ is often 'a protection to the innocent.’ ” Murphy v. Waterfront Comm’n, supra, at 55.
The principles enunciated in our cases construing this privilege, against both statutory and constitutional backdrops, lead unmistakably to the conclusion that the Fifth Amendment requires that a criminal trial judge must give a “no-adverse-inf erence” jury instruction when requested by a defendant to do so.
In Bruno, the Court declared that the failure to instruct as requested was not a mere “technical erro[r] . . . which do[es] not affect . . . substantial rights . . . It stated that the “right of an accused to insist on” the privilege to remain silent is “[o]f a very different order of importance . . .” from the “mere etiquette of trials and . . . the formalities and minutiae of procedure.” 308 U. S., at 293-294. Thus, while the Bruno Court relied on the authority of a federal statute, it is plain that its opinion was influenced by the absolute constitutional guarantee against compulsory self-incrimination.
The Griffin ease stands for the proposition that a defendant must pay no court-imposed price for the exercise of his constitutional privilege not to testify. The penalty was exacted in Griffin by adverse comment on the defendant’s silence; the penalty may be just as severe when there is no adverse comment, but when the jury is left to roam at large with only its untutored instincts to guide it, to draw from the defendant’s silence broad inferences of guilt. Even without adverse comment, the members of a jury, unless instructed otherwise, may well draw adverse inferences from a defendant’s silence.
The significance of a cautionary instruction was forcefully acknowledged in Lakeside, where the Court found no constitutional error even when a no-inference instruction was given over a defendant’s objection. The salutary purpose of the instruction, “to remove from the jury’s deliberations any influence of unspoken adverse inferences,” was deemed so important that it there outweighed the defendant’s own preferred tactics.
We have repeatedly recognized that “instructing a jury in the basic constitutional principles that govern the administration of criminal justice,” Lakeside, 435 U. S., at 342, is often necessary. Jurors are not experts in legal principles; to function effectively, and justly, they must be accurately instructed in the law. Such instructions are perhaps nowhere more important than in the context of the Fifth Amendment privilege against compulsory self-incrimination, since “[t]oo many, even those who should be better advised, view this privilege as a shelter for wrongdoers. They too readily assume that those who invoke it are . . . guilty of crime . . . .” Ullman v. United States, 350 U. S. 422, 426. And, as the Court has stated, “we have not yet attained that certitude about the human mind which would justify us in ... a dogmatic assumption that jurors, if properly admonished, neither could nor would heed the instructions of the trial court . . . .” Bruno, 308 U. S., at 294.
A trial judge has a powerful tool at his disposal to protect the constitutional privilege — the jury instruction — and he has an affirmative constitutional obligation to use that tool when a defendant seeks its employment. No judge can prevent jurors from speculating about why a defendant stands mute in the face of a criminal accusation, but a judge can, and must, if requested to do so, use the unique power of the jury instruction to reduce that speculation to a minimum.
C
The only state interest advanced by Kentucky in refusing a request for such a jury instruction is protection of the defendant: “the requested ‘no inference’ instruction . . . would have been a direct ‘comment’ by the court and would have emphasized the fact that the accused had not testified in his own behalf.” Green v. Commonwealth, 488 S. W. 2d, at 341. This purported justification was specifically rejected in the Lakeside case, where the Court noted that “[i]t would be strange indeed to conclude that this cautionary instruction violates the very constitutional provision it is intended to protect.” 435 U. S., at 339.
Kentucky also argues that in the circumstances of this case the jurors knew they could not make adverse inferences from the petitioner’s election to remain silent because they were instructed to determine guilt “from the evidence alone,” and because failure to testify is not evidence. The Commonwealth’s argument is unpersuasive. Jurors are not lawyers; they do not know the technical meaning of “evidence.” They can be expected to notice a defendant’s failure to testify, and, without limiting instruction, to speculate about incriminating inferences from a defendant’s silence.
The other trial instructions and arguments of counsel that the petitioner’s jurors heard at the trial of this case were no substitute for the explicit instruction that the petitioner’s lawyer requested. Although the jury was instructed that “[t]he law presumes a defendant to be innocent,” it may be doubted that this instruction contributed in a significant way to the jurors’ proper understanding of the petitioner’s failure to testify. Without question, the Fifth Amendment privilege and the presumption of innocence are closely aligned. But these principles serve different functions, and we cannot say that the jury would not have derived “significant additional guidance,” Taylor v. Kentucky, 436 U. S. 478, 484, from the instruction requested. See United States v. Bain, 696 F. 2d 120 (CA5); United States v. English, 409 F. 2d 200, 201 (CA3). And most certainly, defense counsel’s own argument that the petitioner “doesn’t have to take the stand . . . [and] doesn’t have to do anything” cannot have had the purging effect that an instruction from the judge would have had. “[Arguments of counsel cannot substitute for instructions by the court.” Taylor v. Kentucky, supra, at 489.
Finally, Kentucky argues that because the evidence of petitioner’s guilt was “overwhelming and could not be explained,” any constitutional error committed by the state courts was harmless. Chapman v. California, 386 U. S. 18. While it is arguable that a refusal to give an instruction similar to the one that was requested here can never be harmless, cf. Bruno, supra, at 293, we decline to reach the issue, because it was not presented to or considered by the Supreme Court of Kentucky. See Sandstrom v. Montana, 442 U. S. 510, 627.
III
The freedom of a defendant in a criminal trial to remain silent “unless he chooses to speak in the unfettered exercise of his own will” is guaranteed by the Fifth Amendment and made applicable to state criminal proceedings through the Fourteenth. Malloy v. Hogan, 378 U. S., at 8. And the Constitution further guarantees that no adverse inferences are to be drawn from the exercise of that privilege. Griffin v. California, 380 U. S. 609. Just as adverse comment on a defendant’s silence “cuts down on the privilege by making its assertion costly,” id., at 614, the failure to limit the jurors’ speculation on the meaning of that silence, when the defendant makes a timely request that a prophylactic instruction be given, exacts an impermissible toll on the full and free exercise of the privilege. Accordingly, we hold that a state trial judge has the constitutional obligation, upon proper request, to minimize the danger that the jury will give evidentiary weight to a defendant’s failure to testify.
For the reasons stated, the judgment is reversed, and the case is remanded to the Supreme Court of Kentucky for further proceedings not inconsistent with this opinion.
It is so ordered.
The per curiam memorandum opinion of the Supreme Court of Kentucky, Carter v. Commonwealth, No. 79-SC-452-MR, May 13, 1980, is unreported. But the court’s affirmance order is reported in 598 S. W. 2d 763.
Kentucky is one of at least five States that prohibit giving such an instruction to the jury. Others are Minnesota, see State v. Sandve, 279 Minn. 229, 232-234, 156 N. W. 2d 230, 233-234, but see State v. Grey, 256 N. W. 2d 74, 77-78 (the instruction may be necessary in some cases to prevent manifest injustice); Nevada, see Jackson v. State, 84 Nev. 203, 208, 438 P. 2d 795, 798, Nev. Rev. Stat. § 175.181 (1979); Oklahoma, see Brannin v. State, 375 P. 2d 276, 279-280 (Crim. App.), Hanf v. State, 560 P. 2d 207, 212 (Crim. App.); and Wyoming, see Kinney v. State, 36 Wyo. 466, 472, 256 P. 1040, 1042. A few States have a statutory requirement that such an instruction be given to the jury unless the defendant objects. See, e. g., Conn. Gen. Stat. § 54-84 (1958). The majority of the States, by judicial pronouncement, require that a defense request for such a jury instruction be honored. See, e. g., Woodward v. State, 234 Ga. 901, 218 S. E. 2d 629.
After reading the indictment, and inquiring about possible sources of prejudice, the judge told the venire:
“The fact that this man is under a charge or has been indicted has no weight against him as evidence. It is not evidence of his guilt and is not to be considered by you as evidence of his guilt. It is simply a part of the court process which starts, as I have said, the wheels turning to get the case started to be tried. It means nothing more than that. He sits there before you today presumed by the law to be as innocent as anyone else in this courtroom.. I want you to fully understand that. Sometimes it is not easy to do, but you are to put out of your mind the fact that he is accused of this crime to the point where you will consider him in any way guilty until and unless the Commonwealth meets its burden and by that I mean the Commonwealth must prove his guilt to your satisfaction beyond a reasonable doubt and if they fail to do that, you should find him not guilty. . .
Defense counsel summarized his private conversation with his client for the record, observing that “the advice of counsel to Mr. Carter was that in plain terms he was between a rock and hard place . . . .” If the petitioner testified he would be impeached and “if he didn’t testify the jvry[j]- whether Mr. Ruff comment[ed] on it or not would probably use that against him.”
These included the alleged admission that both jackets found in the alley belonged to him.
Defense counsel began his closing argument as follows:
“Ladies and Gentlemen of the jury, I am sure you all right now are wondering well what has happened? Why didn’t Mr. Carter take the stand and testify ? Let me tell you. The judge just read to you that the man is presumed innocent and that it is up to the prosecution to prove him guilty beyond a reasonable doubt. He doesn’t have to take the stand in his own behalf. He doesn’t have to do anything.”
Bruno asked the trial judge to instruct the jury as follows:
“The failure of any defendant to take the witness stand and testify in his own behalf, does not create any presumption against him; the jury is charged that it must not permit that fact to weigh in the slightest degree against any such defendant, nor should this fact enter into the discussions or deliberations of the jury in any manner.” 308 U. S., at 292.
Act of Mar. 16, 1878, ch. 37, 20 Stat. 30, now 18 U. S. C. § 3481, which states in pertinent part:
“In a trial of all persons . . . [the defendant] shall, at his own request, be a competent witness. His failure to make such a request shall not create any presumption against him.”
At common law, defendants in criminal trials could not be compelled to furnish evidence against themselves, but they were also not permitted to testify. In the context of the original enactment of the federal statute found dispositive in the Bruno case, this Court commented on the alteration of this common-law rule: “This rule, while affording great protection to the accused against unfounded accusation, in many cases deprived him from explaining [incriminating] circumstances .... To relieve him from this embarrassment the law was passed. . . . [He] is by the act in question permitted ... to testify ...” Wilson v. United States, 149 U. S. 60, 65-66. Following enactment of the federal statute, the States followed suit with similar laws. See Dills, The Permissibility of Comment on the Defendant’s Failure to Testify in His Own Behalf in Criminal Proceedings, 3 Wash. L. Rev. 161, 164-165 (1928); 8 J. Wigmore, Evidence §2272, p. 427 (J. McNaughton rev. 1961).
The issue in Wilson, supra, was whether it was error for the prosecutor to comment adversely on the defendant’s failure to testify. The Court unanimously held that it was, observing that “[n]othing could have been more effective with the jury to induce them to disregard entirely the presumption of innocence to which by the law he was entitled . . . .” 149 U. S., at 66. As later in Bruno, however, the Court did not reach any Fifth Amendment issue.
The Malloy case overruled Twining v. New Jersey, 211 U. S. 78, and Adamson v. California, 332 U. S. 46, both of which had “adhered to the position that the Federal Constitution does not require the States to accord the Fifth Amendment privilege against self-incrimination.” Tehan v. United States ex rel. Shott, 382 U. S. 406, 412. Malloy established that the same standards determine the validity of claims of Fifth Amendment privilege “whether ... in a state or federal court.” 378 U. S., at 11.
The Court in the Griffin case expressly reserved decision “on whether an accused can require . . . that the jury be instructed that his silence must be disregarded.” 380 U. S., at 615, n. 6.
In Tehan v. United States ex rel. Shott, supra, it was decided that Griffin was not to be given retroactive application.
The Lakeside trial judge gave the following instruction to the jury:
“Under the laws of this State a defendant has the option to take the witness stand in his or her own behalf. If a defendant chooses not to testify, such a circumstance gives rise to no inference or presumption against the defendant, and this must not be considered by you in determining the question of guilt or innocence.” 435 U. S., at 335.
For the history and development of the privilege, which has its roots in English and American revulsion against the inquisitorial practices of the Star Chamber and High Commission, see L. Levy, Origins of the Fifth Amendment (1968); E. Cleary, McCormick on Evidence § 114 (2d ed. 1972); 8 J. Wigmore, Evidence § 2250 (J. McNaughton rev. 1961).
The Court has recognized that there are many reasons unrelated to guilt or innocence for declining to testify:
“It is not every one who can safely venture on the witness stand though entirely innocent of the charge against him. Excessive timidity, nervousness when facing others and attempting to explain transactions of a suspicious character, and offences charged against him, will often confuse and embarrass him to such a degree as to increase rather than remove prejudices against him. It is not every one, however honest, who would, therefore, willingly be placed on the witness stand.” Wilson v. United States, 149 U. S., at 66.
Other reasons include the fear of impeachment by prior convictions (the petitioner’s fear in the present case), or by other damaging information not necessarily relevant to the charge being tried, Griffin, 380 U. S., at 615, and reluctance to “incriminate others whom [defendants] either love or fear,” Lakeside, 435 U. S., at 344, n. 2 (dissenting opinion).
In Griffin, the Court relied on the statutory opinion in Wilson, replacing the words “act” and “statute” with the words “Fifth Amendment.” 380 U. S., at 613. The same can be done here with respect to the Court’s opinion in Bruno: when “Congress” is replaced with “the Fifth Amendment,” “the spirit of the Self-Incrimination Clause is reflected.” Griffin, 380 U. S., at 613-614.
Indeed, the dissenting opinion in Griffin suggested that more harm may flow from the lack of guidance to the jury on the meaning of the Fifth Amendment privilege than from reasonable comment upon the exercise of that privilege. With specific reference to decisions from Kentucky and one other State, the dissenters observed that “[w]ithout limiting instructions, the danger exists that the inferences drawn by the jury may be unfairly broad.” Id., at 623. The Court in Griffin indicated no disagreement with this view.
It has been almost universally thought that juries notice a defendant’s failure to testify. “[T]he jury will, of course, realize this quite evident fact, even though the choice goes unmentioned. ... [It is] a fact inescapably impressed on the jury’s consciousness.” Griffin, supra, at 621, 622 (dissenting opinion). In Lakeside the Court cited an acknowledged authority’s statement that “‘[t]he layman’s natural first suggestion would probably be that the resort to privilege in each instance is a clear confession of crime.’ ” 435 U. S., at 340, n. 10, quoting 8 J. Wigmore, Evidence §2272, p. 426 (J. McNaughton rev. 1961).
In Taylor v. Kentucky, 436 U. S. 478, the Court held that the Due Process Clause requires that instructions be given on the presumption of innocence and the lack of evidential significance of an indictment. The Court recognized that an instruction on the presumption of innocence has a “salutary effect upon lay jurors,” and that “the ordinary citizen well may draw significant additional guidance” from such an instruction. Id., at 484. The Court stressed the “purging” effect of the instruction and the need to protect “the accused’s constitutional right to be judged solely on the basis of proof adduced at trial.” Id., at 486. The same can be said, of course, with respect to the privilege of remaining silent. Indeed, the claim is even more compelling here than in Taylor, where the dissenting opinion noted that “the omission [in Taylor’s trial] did not violate a specific constitutional guarantee, such as the privilege against compulsory self-incrimination.” Id., at 492 (Stevens, J.) (footnote omitted).
“It is obvious that under any system of jury trials the influence of the trial judge on the jury is necessarily and properly of great weight, and that his lightest word or intimation is received with deference, and may prove controlling.” Starr v. United States, 153 U. S. 614, 626. For modern empirical support of this longstanding assumption, see Reed, Jury Simulation: The Impact of Judge’s Instructions and Attorney Tactics on Decisionmaking, 71 J. Crim. L. & C. 68 (1980); Bridgeman & Marlowe, 64 J. Applied Psychology 91 (1979); Cornish & Sealy, Juries and the Rules of Evidence, 1973 Crim. L. Rev. 208, 217-218, 222; Forston, Judge’s Instructions: A Quantitative Analysis of Jurors’ Listening Comprehension, 18 Today’s Speech No. 4, p. 34 (1970).
The importance of a no-inference instruction is underscored by a recent national public opinion survey conducted for the National Center for State Courts, revealing that 37% of those interviewed believed that it is the responsibility of the accused to prove his innocence. 64 A. B. A. J. 653 (1978).
