Peale's works came under criticism from several mental health experts, one of whom directly said Peale was a con man and a fraud. These critics appeared in the early 1950s after the publication of
The Power of Positive Thinking.
Hard to substantiate
One major criticism of
The Power of Positive Thinking is that the book is full of anecdotes that are hard to substantiate. Almost all of the experts and many of the testimonials that Peale quotes as supporting his philosophy are unnamed, unknown and unsourced. Examples include a "famous psychologist,", a two-page letter from a "practicing physician," another famous psychologist, a "prominent citizen of New York City," and dozens, if not hundreds, more unverifiable quotations. Similar scientific studies of questionable validity are also cited. As psychiatrist R. C. Murphy exclaimed "All this advertising is vindicated as it were, by a strict cleaving to the side of part truth," and referred to the work and the quoted material as "implausible and woodenly pious."
Concealed hypnosis
A second major accusation of Peale is that he attempts to conceal that his "techniques" are actually a scientifically well known form of hypnosis, and that Peale attempts to persuade his readers to follow his beliefs through a combination of self-hypnosis and false evidence. While his techniques are not debated by psychologists, Dr. Peale's said his theological practice and strategy was directed more at self analysis, forgiveness, character development, and growth much like the Jesuits of the Catholic Church.
Peale asserts that practicing his "techniques" will give the reader absolute self confidence and deliverance from suffering. The critics, in turn, assert that the repetitive "techniques" are actually a well known form of hypnosis (autosuggestion), hidden under a thin guise with the use of terms which may sound more benign from the reader's point of view ("techniques", "formulas," "methods," "prayers," and "prescriptions."). One author called Peale's book "The Bible of American autohypnotism."
Psychiatrist R.C. Murphy writes "Self knowledge, in Mr. Peale's understanding is unequivocally bad: self hypnosis is good." Murphy adds that the repeated hypnosis defeats an individual's self motivation, self knowledge, unique sense of self, sense of reality, and the ability to think critically. Murphy calls Peale's understanding of the mind inaccurate, "without depth," and Peale's description of the workings of the mind and the unconscious mind as deceptively simplistic and false: "It is the very shallowness of his concept of 'person' that makes his rules appear easy ... If the unconscious of man ... can be conceptualized as a container for a small number of psychic fragments, then ideas like 'mind-drainage' follow. So does the reliance on self-hypnosis, which is the cornerstone of Mr. Peale's philosophy.'"
Psychologist Albert Ellis, the founder of cognitive therapy and influential psychologist of the 20th century, compares the Peale techniques with those of the hypnotist Emile Coue, and Ellis says that the repeated use of these hypnotic techniques could lead to significant mental health problems. Ellis has documented in several books the many individuals he has treated who suffered mental breakdowns from following Peale's teachings. Ellis' writings repeatedly warn the public not to follow the Peale message. Ellis contends the Peale approach is dangerous, distorted, unrealistic. He compares the black or white view of life that Peale teaches to a psychological disorder (Borderline personality disorder), perhaps implying that dangerous mental habits which he sees in the disorder may be brought on by following the teaching. "In the long run [Peale's teachings] lead to failure and disillusionment, and not only boomerang back against people, but often prejudice them against effective therapy."
Exaggerated fears
A third major criticism is that Peale's philosophy is based on exaggerating the fears of his readers and followers, and that this exaggerated fear inevitably leads to aggression and the destruction of those considered "negative." Peale's views are critically reviewed in a 1955 article by psychiatrist R. C. Murphy, published in
The Nation, titled "Think Right: Reverend Peale's Panacea."
With saccharine terrorism, Mr. Peale refuses to allow his followers to hear, speak or see any evil. For him real human suffering does not exist; there is no such thing as murderous rage, suicidal despair, cruelty, lust, greed, mass poverty, or illiteracy. All these things he would dismiss as trivial mental processes which will evaporate if thoughts are simply turned into more cheerful channels. This attitude is so unpleasant it bears some search for its real meaning. It is clearly not a genuine denial of evil but rather a horror of it. A person turns his eyes away from human bestiality and the suffering it evokes only if he cannot stand to look at it. By doing so he affirms the evil to be absolute, he looks away only when he feels that nothing can be done about it ... The belief in pure evil, an area of experience beyond the possibility of help or redemption, is automatically a summons to action: 'evil' means 'that which must be attacked ... ' Between races for instance, this belief leads to prejudice. In child-rearing it drives parents into trying to obliterate rather than trying to nurture one or another area of the child's emerging personality ... In international relationships it leads to war. As soon as a religious authority endorses our capacity for hatred, either by refusing to recognize unpleasantness in the style of Mr Peale or in the more classical style of setting up a nice comfortable Satan to hate, it lulls our struggles for growth to a standstill ... Thus Mr Peale's book is not only inadequate for our needs but even undertakes to drown out the fragile inner voice which is the spur to inner growth.
Harvard Scholar Donald Meyer would seem to agree with this assessment, presenting similar warnings of a religious nature. In his article "Confidence Man", Meyer writes, "In more classic literature, this sort of pretension to mastery has often been thought to indicate an alliance with a Lower rather than a Higher power." The mastery Peale speaks of is not the mastery of skills or tasks, but the mastery of fleeing and avoiding one's own "negative thoughts." Meyer writes this exaggerated fear inevitably leads to aggression:"[B]attle it is; Peale, in sublime betrayal of the aggression within his philosophy of peace, talks of 'shooting' prayers at people."
Psychologist Martin Seligman, former APA president and the founder of the branch of psychology known as "positive psychology", says "positive thinking" (bearing no resemblance to his own "positive psychology") is unproven, dangerous. He cautions readers not to confuse the two approaches. "First, positive thinking is an armchair activity. Positive psychology, on the other hand, is tied to a program of empirical and replicable scientific activity ... Where accuracy is tied to potentially catastrophic outcomes (for example, when an airline pilot is deciding whether to de-ice the wings of her airplane) we should all be pessimists ... Positive psychology is a supplement to negative psychology, not a substitute.".
