In 2011 Daryl Bem published a series of ten studies which he claimed demonstrated psi phenomena – that people could “feel the future”. He took standard psychological study methods and simply reversed the order of events, so that the effect was measured prior to the stimulus. There is, rather, a continuum, so when studying “pseudoscience” experts are actually studying science. In fact, we already knew what was wrong, and how Bem’s research was a prime example of it. It’s hard to know how many fixes would have been put in place without the stimulus of Bem’s research.
