In Computing Machinery and Intelligence (1950) Alan Turing claims that "the statistical evidence [for Extrasensory Perception], at least for telepathy, is overwhleming".

My Google searches have largely turned up pseudo-scientific nonsense and I wondered if anyone here could point me in the direction of the statistical evidence Turing thought was "overwhelming"?

    This question appears to be off-topic because it is about the motivations on an individual, which we cannot definitively answer.

    @ChrisW: At that point, we realise Turing is no authority on this and cites no references, and we should change the question to "Is there overwhelming statistical evidence of telepath?" then simplify it to "Does telepathy exist?" and then mark it as a duplicate of skeptics.stackexchange.com/questions/361/does-telepathy-exist

    It's a history question: not whether there is (now) statistical evidence, but whether there was (in Alan Turing's possession) evidence.

    @ChrisW It was most likely the the Rhine data then, which was compelling at the time but it largely dismissed now due to experimental design and inability to replicate the results. Incidentally "Extrasensory Perception After Sixty Years" (1940) by Rhine et al is credited as being the first meta-analysis in the history of science.

    @ChrisW - Thanks very much for the SO link, I am in total agreement with that answer in that the paragraph on ESP is odd (though I can't convince myself that Turing was intending for it to be tongue in cheek). Thanks all for pointing out Rhine, exactly what I was looking for. While I am a relatively prolific SO user and this was the first time I had posted a question on skeptics, so I am in no position to question the classification as Off-topic, but I will suggest that if skeptics wishes to attract a strong user base, a gentler approach to newcomers might be worth considering.
