I just read this great article in Wired Magazine from May 2009. Excerpt:
Daryl BemProfessorEmeritus of PsychologyCornell UniversityObject of Study: Precognition
It’s deja vu in advance: In conventional psychological tests, subjects recall words they’ve had a chance to study better than words they’ve seen only briefly. Bem reversed the usual order of events and found that his subjects were significantly more likely to recall words they would study later than words they wouldn’t study at all. Extroverts show the most precognition.
