So you honestly believe that people investigated something for which there was no evidence and no reason to believe for .... I don’t know what reason. That the USA & USSR both explored it and tested it because .... they had no reason to believe it to be true? (Surely the USSR didn’t have cash to flash around on things with no evidence.) People believe in a lot of whacky things but they tend to carefully avoid subjecting those things to scientific scrutiny if they have no reason to believe them true. Why would they subject them to such scrutiny again and again and again only to be dissappointed every time if it was merely quackery? I don’t understand those motivations.
They tried to prove their superstitions and failed. Turing even falsely announced that the evidence for telepathy was "overwhelming."
Your faith in the rationality of Communism is misplaced.
Look up Lysenkoism.
