LiveScience is reporting on experiments done by researchers at three universities trying to replicate Daryl Bem‘s 2010 claim that he had found scientific proof of psychic ability. The researchers Stuart Ritchie of the University of Edinburgh, University of Hertfordshire psychologist Richard Wiseman and University of London psychologist Christopher French all conducted the experiment separately at their respective universities with 50 participants each.
The researchers chose the strongest of the eight positive findings that Bem originally published. In the experiment, Bem’s participants seemed to reverse the usual cause-effect sequence of time. They saw a list of 48 words flashed onto a computer screen and were then treated to a surprise memory test in which they were asked to type in as many of the words as they remembered.
Next, a random sample of 24 of the previous 48 words was presented again. The participants did some practice exercises with these words, and then the experiment ended. Analyzing the memory-test results, Bem and his colleagues found that the students were more likely to recall the words that they’d soon see again than the words that were not on the later exercise list, as if they could see the future.
“It’s almost as if you study for an exam, you do the exam and then you study for it afterwards and then you get a better mark,” Ritchie told LiveScience. “So you can see why we were kind of surprised by that.”
Bem encouraged replication of his results, and he put the computer program he used in his experiment online so other researchers could use it.
