Why I don't believe in precognition | Psychology Today:

In a paper to be published by the Journal of Personality and Social Psychology (JPSP), Daryl Bem notes that 34% of psychologists in one studied sample believe that psi is impossible. I would be among those 34% if I were sampled. Yet, I remain intrigued by attempts to prove the existence of psi. Bem defines psi as 'anomalous processes of information or energy transfer that are currently unexplained in terms of known physical or biological mechanisms.' In his paper, he reports the results of 9 experiments focusing on precognition and premonition, which he defines as 'the anomalous retroactive influence of some future event on an individual's current response.'
