Hasted is, as I recall, the remarkably credulous physicist who wrote a book called The Metal Benders. He experimented with children a great deal, since children "wouldn't cheat"....
I actually read the thing, and I believe (it's been a while) that Martin Gardner wrote an article dissecting the book.
Among the wonders found by Hasted was that his children couldn't perform while being observed... They only produced results when allowed to work with the test items alone. He dubbed this the "shyness effect".....
Well, what Martin Gardner has written is the final truth here, it seems. I have never seen him being criticized here. Factually Gardner carefully chose his facts, twisted the facts and even wrote outright lies. Some examples:
Martin Gardner (1981/1989), 'Science; Good, Bad and Bogus', (p. 93) about the experiments John Taylor made with child metal benders:
Oddly, Taylor never sees anything bend, …" (italics MG).
John Taylor (1975), 'Superminds' (p. 74):
I saw a strip of silver bend up and flop over on being rubbed gently by one subject.
Although Taylor was remarkably scanty with details, this was what he wrote and Gardner had read it, I assume.
Martin Gardner (1981/1989), 'Science; Good, Bad and Bogus', (p. 205) about the glass spheres of Hasted:
Other experimenters have had no difficulty twisting paper clips and pushing them into such globes where they intertwine to form tight scrunches, and to do it in just a few minutes.
It is absolutely certain there have never been such experimenters.
Martin Gardner (1983), 'The whys of a philosophical scrivener'. New York, Quill:
How can the public know that for fifty years skeptical psychologists have been trying their best to replicate classic psi experiments, and with notable unsuccess? It is this fact more than any other that has led to parapsychology's perpetual stagnation. Positive evidence keeps coming from a tiny group of enthusiasts, while negative evidence keeps coming from a much larger group of skeptics.

Gardner does not attempt to document this assertion, nor could he. It is pure fiction. Look for the skeptics' experiments and see what you find.
