Opinion of Blackmun, J.
the arguments by both the prosecution and the defense relating to petitioner's future dangerousness, and the obvious relevance of petitioner's parole ineligibility to the jury's formidable sentencing task. While juries ordinarily are presumed to follow the court's instructions, see Greer v. Miller, 483 U. S. 756, 766, n. 8 (1987), we have recognized that in some circumstances "the risk that the jury will not, or cannot, follow instructions is so great, and the consequences of failure so vital to the defendant, that the practical and human limitations of the jury system cannot be ignored." Bruton v. United States, 391 U. S. 123, 135 (1968). See also Beck v. Alabama, 447 U. S. 625, 642 (1980); Barclay v. Florida, 463 U. S., at 950 ("Any sentencing decision calls for the exercise of judgment. It is neither possible nor desirable for a person to whom the State entrusts an important judgment to decide in a vacuum, as if he had no experiences").
But even if the trial court's instruction successfully prevented the jury from considering parole, petitioner's due process rights still were not honored. Because petitioner's future dangerousness was at issue, he was entitled to inform the jury of his parole ineligibility. An instruction directing the jury not to consider the defendant's likely conduct in prison would not have satisfied due process in Skipper v. South Carolina, 476 U. S. 1 (1986), and, for the same reasons, the instruction issued by the trial court in this case does not satisfy due process.
IV
The State may not create a false dilemma by advancing generalized arguments regarding the defendant's future dangerousness while, at the same time, preventing the jury from learning that the defendant never will be released on parole. The judgment of the South Carolina Supreme Court accordingly is reversed, and the case is remanded for further proceedings.
It is so ordered.
