A Critical Examination of the Blackmore Psi Experiments
Abstract
A critical examination of Susan Blackmore’s psi experiment database was undertaken to assess the claims of consistent “no ESP†across these studies. Many inconsistencies in the experimental reports were found, and their serious consequences are discussed. Discrepancies were found between the unpublished experimental reports and their published counterparts. “Flaws†were invoked to dismiss significant results while other flaws were ignored when studies produced nonsignificant results. Experiments that were admittedly flawed in the unpublished reports were mixed with supposedly unflawed studies and published without segregation, creating the impression of methodological soundness. Two instances in which study chronology was reordered were found. Overall, it is concluded that Blackmore’s claims that her database shows no evidence of psi are unfounded, because the vast majority of her studies were carelessly designed, executed, and reported, and, in Blackmore’s own assessment, individually flawed. As such, no conclusions should be drawn from this database.
