tutional guarantees. Boykin v. Alabama, 395 U. S. 238, 243 (1969) (pleading guilty implicates the Fifth Amendment privilege against self-incrimination, the Sixth Amendment right to confront one's accusers, and the Sixth Amendment right to trial by jury). Given the seriousness of the matter, the Constitution insists, among other things, that the defendant enter a guilty plea that is "voluntary" and that the defendant must make related waivers "knowing[ly], intelligent[ly], [and] with sufficient awareness of the relevant circumstances and likely consequences." Brady v. United States, 397 U. S. 742, 748 (1970); see also Boykin, supra, at 242.
In this case, the Ninth Circuit in effect held that a guilty plea is not "voluntary" (and that the defendant could not, by pleading guilty, waive her right to a fair trial) unless the prosecutors first made the same disclosure of material impeachment information that the prosecutors would have had to make had the defendant insisted upon a trial. We must decide whether the Constitution requires that preguilty plea disclosure of impeachment information. We conclude that it does not.
First, impeachment information is special in relation to the fairness of a trial, not in respect to whether a plea is voluntary ("knowing," "intelligent," and "sufficient[ly] aware"). Of course, the more information the defendant has, the more aware he is of the likely consequences of a plea, waiver, or decision, and the wiser that decision will likely be. But the Constitution does not require the prosecutor to share all useful information with the defendant. Weatherford v. Bursey, 429 U. S. 545, 559 (1977) ("There is no general constitutional right to discovery in a criminal case"). And the law ordinarily considers a waiver knowing, intelligent, and sufficiently aware if the defendant fully understands the nature of the right and how it would likely apply in general in the circumstances—even though the defendant may not know the specific detailed consequences of invoking it. A defendant, for example, may waive his right to remain silent, his
