I understand your concern, but when you really think about it, what human capabilities are perfectly replicable on demand? For example, even the best hitter is major league baseball cannot hit on demand. That why there are batting averages. Nor can we predict when they will hit a homerun. It’s rare for players to consistently hit home runs. In fact, we cannot even predict whether or not a home run will occur in a given baseball game, but that doesn’t mean home runs do not exist (Utts, 1995). If there really truly is an effect, it may not ever be replicable on demand in the short term even if we understand how it works, i.e. a batter may not hit one home run in this game or the next, but over his career he may have several. Similarly, in the long run, in well-controlled laboratory experiments, we should see a consistent level of functioning that is above chance. There are many labs that have replicated remote viewing experiments, by various experimenters and in different cultures (Utts, 1995). With such strong results, were it not such an unusual field, we would no longer question as a real phenomenon. It is highly unlikely that methodological problems could account for the consistency of the results because the various experiments have been different enough that there would have to be a different explanation for each type of experiment (Utts, 1995). It would take a considerable amount of fraud on the part of a large number of experimenters and subjects for the results of remote viewing experiments to be completely invalid.
