Hamm v. Smith · ¶160

Moore did not mandate the Eleventh Circuit's approach, either. As I have already explained, Moore prohibited courts from using extrinsic facts about a defendant to draw conclusions about where his “true” IQ falls within a confidence interval. Beyond that, Moore's IQ discussion merely reaffirmed Hall's holding that courts must consider the standard error of measurement when applying a 70-IQ cutoff to a single score. 581 U. S., at 14. Moore did not articulate any rules about analyzing multiple scores in aggregate. As in Hall, the defendant in Moore had multiple IQ scores in the record, id., at 10, but neither the Texas court nor this Court considered those scores collectively, see Ex parte Moore, 470 S. W. 3d, at 519; Moore, 581 U. S., at 14.
