The Federal Rules of Evidence exclude expert scientific testimony when it has been developed without regard for accepted scientific methods.

This case focuses on expert scientific evidence. Such evidence plays a vital and often dispositive role in modern litigation. For scientific evidence to be helpful to the factfinder it must meet some minimal threshold of reliability. To hold otherwise would be to allow a system of adjudication based more on chance than on reason.
