Matthew Walker

“One consistent experience in all these experiments is the fact that the number of hits scored tends to sink after the first attempt, and the results then become negative. But if, for some inner or outer reason, there is a freshening of interest on the subject’s part, the score rises again. Lack of interest and boredom are negative factors; enthusiasm, positive expectation, hope, and belief in the possibility of ESP make for good results and seem to be the real conditions which determine whether there are going to be any results at all.”
