Full Idea
Wegener's theory of continental drift was only accepted when the theory of plate tectonics was developed, providing a mechanism. While some correlations exist for parapsychology, lack of plausible mechanisms leaves it as speculation.
Clarification
'Parapsychology' is supernatural actions of the mind
Gist of Idea
Parapsychology is mere speculation, because it offers no mechanisms for its working

A Reaction
But parapsychology is not even on a par with Wegener's speculation, because his was consistent with known physical laws, whereas parapsychology flatly contradicts them. The so-called correlations are also not properly established.
