How later courts describe this case

• Daubert framework applies to social sciences, but “the measure of intellectual rigor will vary by the field of expertise and the way of demonstrating expertise will also vary”
• “When the trial court concludes, on substantial evidence, that [a witness’s] professed lapses of memory are false, evasive devices to avoid truthful answers, it may admit, as ‘inconsistent,’ the witness’s prior statements describing the events the witness now claims to have forgotten.”
