It's the catch-all explanation used for all manner of beliefs and subjective anecdote, everything from healing crystals to talking to tomato plants and all in-between. The idea that something is happening but this something is just waiting for the men in white coats to discover it. It certainly is appealing (and possible, but probable..?)
There is another explanation. An obvious one even. But of course no one with vested interest would dare open this Pandora's box. That would be daft.
