When To Believe And When Not To

Bizarre effects in quantum mechanics. Recently, three "delayed choice" experiments have been consummated in physics labs. In such experiments, the result depends upon what the observer tries to measure; viz., light as particulate-in-nature or light as wave-like-in-nature. The funny thing is that it doesn't matter when the experimenter decides what to measure; he can do this months before the experiment or even afterwards! The effect of the choice is the same -- before or after. Now that is weird! But everyone believes it because a theory for it exists.

Bizarre effects in psychokinesis. Recently, several laboratories have been trying to determine if the human mind can affect random physical events, such as radioactive decay.

"Surprisingly, the PK effect appears quite independent of physical variables, such as the distance or the complexity of the random generator. The subjects succeed by aiming at the result, regardless of the intermediate steps required to reach this result. Such a goal-oriented, even non-casual feature of PK has been emphasized by PK experiments with pre-recorded, random events. In these experiments, random events were first pre-recorded, and later played back to a PK subject who tried to enforce a certain outcome. These experiments gave positive results, even though the subject's mental effort occurred after the random events had been macroscopically recorded."

Now, that is weird, too! (In fact, one paragraph echos the other.) But of course almost no one believes in PK because there is no theory for it.
