Carroll, Robert Todd. "A Short History of Psi Research". The Skeptic's Dictionary . Retrieved 28 March 2016. "Others examined Coover’s data and found more than Coover did. Radin writes that the receivers’ ability to guess the right cards rated 160 to 1 against chance (1997: 65). F. C. S. Schiller found the data showed odds greater than 50,000 to 1 against chance, but he used only the data from the fourteen highest-scoring subjects. Coover replied that he could find all kinds of interesting antichance events if he were selective in his use of the data (Hansel 1989: 28). In 1939, psychologist Robert Thouless (d. 1984) found that if the data were lumped together from the main experiment, there were 44 more hits than expected by chance. Thouless suggested that the data supported some slight psychic effect. He calculated the odds of this happening by chance to be about 200 to 1. Coover attributed the excess hits to recording errors on the part of the experimenter."
