Cayce advocated
pseudohistorical ideas in his trance readings, such as the existence of
Atlantis and the discredited theory of
polygenism.
[73] In many trance sessions, he reinterpreted the
history of life on earth. One of Cayce's controversial theories was polygenism. According to Cayce, five races (
white,
black, red, brown, and yellow) were created separately and simultaneously on different parts of Earth.
[73] He accepted the existence of
aliens and Atlantis (saying that "the red race developed in Atlantis and its development was rapid"), and believed that "soul-entities" on Earth intermingled with animals to produce "things" such as
giants which were as tall as 12 feet (3.7 m).

In his 2003 book
The Skeptic's Dictionary, philosopher and skeptic
Robert Todd Carroll wrote: "Cayce is one of the main people responsible for some of the sillier notions about Atlantis."
[74] Carroll cited some of Cayce's discredited ideas, including his belief in a giant crystal (activated by the sun to harness energy and provide power on Atlantis) and his prediction that in 1958, the United States would rediscover a
death ray which had been used on Atlantis.
[74]
During the 1930s, Cayce incorrectly predicted that North America would experience existential chaos: "Los Angeles, San Francisco ... will be among those that will be destroyed before New York".
[75] He also predicted that the
Second Coming of Christ would occur in 1998.
[76]
Science writers and
skeptics say that Cayce's reported
psychic abilities were faked or non-existent.
[77][78][79] Health experts are critical of his unorthodox treatments, such as his promotion of
pseudoscientific dieting and homeopathic remedies, which they consider
quackery.
[80][81]
Evidence of Cayce's reported clairvoyance was derived from
newspaper articles,
affidavits,
anecdotes,
testimonials and books, rather than
empirical evidence which can be independently evaluated.
Martin Gardner wrote that the "verified" claims and descriptions from Cayce's trances can be traced to ideas in books he had been reading by authors such as
Carl Jung,
P. D. Ouspensky, and
Helena Blavatsky. Gardner concluded that Cayce's trance readings contain "little bits of information gleaned from here and there in the occult literature, spiced with occasional novelties from Cayce's unconscious".
[82]
Michael Shermer wrote in
Why People Believe Weird Things (1997), "Uneducated beyond the ninth grade, Cayce acquired his broad knowledge through voracious reading and from this he wove elaborate tales."
[83] According to Shermer, "Cayce was fantasy-prone from his youth, often talking with angels and receiving visions of his dead grandfather." Magician
James Randi said, "Cayce was fond of expressions like 'I feel that' and 'perhaps'—qualifying words used to avoid positive declarations."
[84] According to investigator
Joe Nickell,
Although Cayce was never subjected to proper testing, ESP pioneer
Joseph B. Rhine of Duke University—who should have been sympathetic to Cayce's claims—was unimpressed. A reading that Cayce gave for Rhine's daughter was notably inaccurate. Frequently, Cayce was even wider off the mark, as when he provided diagnoses of subjects
who had died since the letters requesting the readings were sent.

Science writer
Karen Stollznow wrote,
The reality is that his cures were hearsay and his treatments were folk remedies that were useless at best and dangerous at worse ... Cayce wasn't able to cure his own cousin, or his own son who died as a baby. Many of Cayce's readings took place after the patient had already died.
[86]
Cayce's Association for Research and Enlightenment has also been criticized for promoting
pseudoscience.
