In the middle of the XIX century, when the judicial authorities in the various countries were guided by the idea of ​​free will, the crime is considered as a sin that needs to be atoned. In the late 1850s, a doctor from France Morel BA laid the basis for criminal anthropology. Galton advocated the use of special measures that would limit childbearing not only criminals, mentally retarded and mentally ill, but also for the poor. In 1876, after five years from the publication of Darwin's book "Origin of Man", the Italian physician and criminologist Cesare Lombroso published his book "Outlaw", which tried to demonstrate bioprirodu crime.

Psychological Association in the United States report, "Intelligence: the unknown and the known," notes that the correlation between crime and IQ is 0.2 (feedback). Correlation of 0.2 means that the differences in crime are less than 4 percent. It is important to realize that the causal relationship between IQ test scores and social consequences may be indirect. Children with poor school performance may feel alienated and so they may be more likely to make a legal violation, compared with children who have a good academic record. 

In the book «g-factor" (1998) Arthur Dzhensen cites data in accordance with which people with IQ in the range of 70-90, regardless of race make more legal violations, rather than people with an IQ above or below this range, with the peak of crime at 80-90.
