In the 1950s a psychologist, Stanton Samenow, and a psychiatrist, Samuel Yochelson, sharing the conventional wisdom that crime is caused by environment, set out to prove their point. They began a 17-year study involving thousands of hours of clinical testing of 250 inmates here in the District of Columbia.
To their astonishment, they discovered that the cause of crime cannot be traced to environment, poverty, or oppression. Instead, crime is the result of individuals making, as they put it, wrong moral choices. In their 1977 work The Criminal Personality, they concluded that the answer to crime is a "conversion of the wrong-doer to a more responsible lifestyle."
In 1987, Harvard professors James Q. Wilson and Richard J. Herrnstein came to similar conclusions in their book Crime and Human Nature. They determined that the cause of crime is a lack of proper moral training among young people during the morally formative years, particularly ages one to six.
