Can the present affect the past?
It looks like it:
In a test that we wouldn't have believed had it not been documented, 100 Cornell students were shown 48 common nouns and given three seconds to observe and visualize each word. Then they were asked to type out as many words as they could remember. After that, a computer re-displayed half of those [original 48] words, which the students then retyped.
You don't have to be psychic to know where we're going with this: It turns out that the students more likely recalled the words that they were later asked to retype.
In his original paper, Dr. Bem wrote, “The results show that practicing a set of words after the recall test does, in fact, reach back in time to facilitate the recall of those words.”
This is similar to some of the things Dean Radin talks about in “Science and the taboo of psi
”. He mentions an experiment where people react to unpleasant pictures before
they are shown.
