of human behavior." The Individual Psychology Bulletin also criticized Hubbard for "not offer any other evidence than a vague reference to hundreds of cured patients, without furnishing case histories or other specific data. The book is crammed with bragging and swaggering, pseudoscientific bombast, platitudes and vulgarities, and a great deal of sheer nonsense." British health minister Kenneth Robinson, among others, expressed concern at the possible dangers of unskilled amateurs practicing therapy on patients, and skepticism about Hubbard's claims that Dianetics could be effective in dealing with illnesses. In September 1950, the American Psychological Association issued a resolution calling on psychologists not to use Hubbard's methods for treatment purposes unless and until they had been shown effective through scientific testing. Complaints were made against local Dianetics practitioners for allegedly practicing medicine without a license. This eventually prompted Dianetics advocates to disclaim any medicinal benefits in order to avoid regulation. Hubbard explained the backlash as a response from various entities trying to co-opt Dianetics for their own use. He claimed that "just about the time hit the stands" (i.e. April–May 1950), a "very high-ranking officer" of the US Navy had approached him to sound him out about "using what you know about the mind to make people more suggestible." Hubbard apparently avoided this by resigning from the Navy. He also told the FBI in a 1952 interview that "the Soviets apparently realized the value of Dianetics because as early as 1938 an official of Amtorg , while at The Explorers Club in New York, contacted him to suggest that he go to Russia and develop Dianetics there." The FBI agent conducting the interview was not convinced, describing Hubbard as "a mental case". Hubbard blamed the hostile press coverage in particular on a plot by the American Communist Party, working through the Authors League of America. According to Hubbard, These people in the early days of Dianetics said, "We can use Dianetics." They were all my friends. Everywhere I looked, every writer I knew who had ever been a member of the Communist Party was right there alongside of me pumping my hand, saying, "Good going, Ron. We knew you had it in you." ... And when they finally got it through their thick skulls in October 1950 that I didn't care to have Dianetics and Scientology covertly used by any other organization on Earth for their own special purposes, Dianetics and Scientology
