I'd suggest that those interested in the question find a copy of Mark Cliffton's 'Sense From Thought Divide', a great little story from '55 about a government agency doing PSI research.
Like Asimov's "Belief", Mark Clifton's classic short story "Sense from Thought Divide" (March 1955) deals with a clash between belief systems and new discoveries. But here, it's not only the scientists whose beliefs are being pushed to their limits...
"Do you realize, Swami," I asked, "that the one great drawback throughout the ages to a full acceptance of psi is the lack of permanent evidence? It has always been evanescent, perishable. It always rests solely upon the word of witnesses..."
I opened my lower desk drawer and pulled out a couple of the Auerbach cylinders which we had used the night before. I laid them on top of the desk. "These cylinders," I said, "act like photographic film. They will record, in permanent form, the psi effects you command. At last, for all mankind the doubt will be stilled; man will at once know the truth; and you will take you place among the immortals." I thought it was pretty good, and that, with his overweening ego, it would surely do the trick. But the Swami was staring at the cylinders first in fascination, then fear, then in horror. He jumped to his feet, without bothering to swirl his robe majestically, rushed over to the door, fumbled with the knob as if he were in a burning room, managed to get the door open, and rushed outside...
I drew a deep breath, and exhaled it audibly. My testing procedures hadn't produced the results I'd expected, but the last one had revealed something else. The Swami believed himself to be a fraud!
