Does anyone have an explanation of why experimenters failed to replicate the results of Dr. Bem's original experiment? In both experiments, the subjects viewed a list of words on a computer and then typed as many of the words as they could remember. Later, the computer randomly selected some words from the original group of words presented to the subjects and showed them again. The original experiment by Dr. Bem found that subjects remembered more of the words that they saw later than words that weren't shown to them later, indicating that the subject's ability to remember words was affected by precognition of seeing the words in the future. However, the experimenters attempting to replicate the results by Dr. Bem failed:

Could the failure have something to do with the fact that the subjects in both studies were told that the experiment was designed to test psychic ability? Or, even though experimenters weren't involved much in the computer run experiment, could the bias of the second experimenters against psy ability (as demonstrated in the snide title of their article) be somehow responsible for the failure. If so, I don't see how, because they left the room and didn't know how the subjects were doing while they took the test on a computer. Thanks for taking the time to consider this!
