criticized Radin for his selective historical overview of parapsychology and for ignoring clear evidence of fraud. French recounts that the medium Florence Cook was caught in acts of trickery and two of the Fox sisters confessed to fraud, but that Radin did not mention this fact. Radin has claimed the results from parapsychological research are as consistent by the same standards as any other scientific discipline, but Ray Hyman has written that many parapsychologists disagree with this, openly admitting that the evidence for parapsychology is "inconsistent, irreproducible, and fails to meet acceptable scientific standards". Radin and his colleagues have suggested that small-scale studies have produced a "genuine psychokinetic effect", but critics have asserted that Radin has not shown evidence that the null hypothesis of such an effect could be confidently rejected. Further, psychologists David B. Wilson and William R. Shadish, writing in Psychological Bulletin, criticized claims made by Radin and his associates that human minds can psychically influence random number generators, saying that parapsychologists "need to go beyond statistics and explain how the mind might influence a computer, then test that prediction". Radin has appealed to quantum mechanics as a mechanism, claiming that it can explain the non-locality and backward causality associated with psi phenomena, though such ideas are harshly criticized by many physicists who study quantum mechanics as being pseudoscientific. Radin has written that not all people experience paranormal phenomena (or see ghosts) because they block such signals due to the process of latent inhibition. Books While Radin's books have been reviewed favorably by groups that give general reviews such as Publishers Weekly and Kirkus Reviews, independent reviews by scientists and skeptics, as cited below, have often been negative. The Conscious Universe A critical review of The Conscious Universe: The Scientific Truth of Psychic Phenomena (1997) was published by the British mathematician I. J. Good in Nature. Good wrote about flaws in Radin's method for evaluating the file-drawer effect. He stated that the book avoided mentioning the evidence of fraud in parapsychology. Radin replied to Good in a follow-up letter in the correspondence pages of Nature, saying that Good in his review had misinterpreted a reference to a probability value. Good replied, saying that most readers would not arrive at the same interpretation of what Radin had written noting that readers would be surprised to learn that by "more than a billion trillion", Radin meant more than 10100".
