[1][better source needed] Radin was elected president of the Parapsychological Association in 1988, 1993, 1998, and 2005, and has published a number of articles and papers supporting the existence of paranormal phenomena, as well as two books directed to a popular audience: The Conscious Universe and Entangled Minds.
[9] Radin believes that parapsychology is as repeatable as any scientific discipline, but that it is also, as paraphrased by sociologist Erich Goode, "elusive, subtle and complex", a field of study that is "difficult to replicate" and that "our understanding of it is incomplete".
In spite of all the tests devised by parapsychologists like Jahn and Radin, and huge amounts of data collected over a period of many years, the results are no more convincing today than when they began their experiments.
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.
[10][a][6][18] 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.
[25] In 2002, Victor J. Stenger gave a criticism of The Conscious Universe that aligned with Good's arguments that Radin did not perform the file-drawer analysis correctly, made fundamental errors in his calculations, and ignored non-paranormal explanations for the data.
[21][27] Publishers Weekly has reviewed it, saying of the book, that it is "unfocused and opaque at times" but "nevertheless an admirable attempt to bridge the gap between the scientific and the spiritual realm".
[22] Dale DeBakcsy, writing for the Skeptical Inquirer, a bimonthly American general-audience magazine published by the Committee for Skeptical Inquiry, reviewed Supernormal and criticized the work as "misrepresenting report data, lowering success criteria, and playing a somewhat loose game with how rigorously confidence information is presented".
Debakcsy examined Radin's claim that a meta-analysis of forced choice recognition published in parapsychological literature showed that Psi effects were present above chance to a probability of 1015 to 1, noting that the study also reported that results varied wildly with an extremely unusual standard deviation, such that they dropped 10% of the most extreme variations which reduced the effect size.
"Radin wrote that the subject's response "successfully" described the actual randomly selected location of the distant agent: the Radio telescope at Kitt Peak.
