As I wrote when I first reported on this study, "Bem has replied to his critics and stands by his findings. Ultimately, of course, either the findings will stand the test of time and be replicated by other researchers, or they won't."

Replication is of course the hallmark of valid scientific research-if the findings are true and accurate, they should be able to be replicated by others. Otherwise the results may simply be due to normal and expected statistical variations and errors. If other experimenters cannot get the same result using the same techniques, it's usually a sign that the original study was flawed in one or more ways.
So far it's not looking good for psychics; the experiment was replicated, and failed. A team of researchers Professor Chris French (Goldsmiths, University of London), Stuart Ritchie (University of Edinburgh) and Professor Richard Wiseman (University of Hertfordshire) collaborated to accurately replicate Bem's final experiment, and found no evidence for precognition. Their results were published in the journal PLoS ONE.
