Interestingly, in the ESP literature, the phenomenon of "psi missing" (significantly worse than chance performance) has sometimes been interpreted as evidence for ESP. See:
http://www.highbeam.com/doc/1G1-60898897.html (although I don't believe this provides access to the full article...sorry). Unless Bem unambiguously rejects the concept of psi missing (which would put him at odds with some other parapsychologists), this interpretation of below chance performance raises further questions about his reliance on one-tailed tests. ...Scott Scott O.
