A better replication: Repeat tasks with above chance performers

Posted by avjaeggi on 16 Mar 2012 at 00:38 GMT

Why not do the following: Take the subjects who were performing above chance in Bem's experiments and test them again (and again, and again) on the same and different tasks? If there's something to psi, then surely these subjects should show it repeatedly. If that's the case, one could actually start getting at the mechanisms, e.g. by putting them in an fMRI scanner. If there's nothing to it, then the failure to replicate the results in the same subjects will demonstrate this conclusively
