Anastaska 's Key Ideas from The Causes and Cures of Criminality
by Hans J. Eysenck, Gisli H. Gudjonsson

Psychological factors in criminality relate to genetic and constitutional causes and to personality and other sources of individual differences . Such factors have often been misunderstood, and even more frequently misinterpreted, in the context of crime and crime prevention.

To say, as we shall do as a result of a very extensive body of evidence, that genetic factors are powerfully involved in criminal activity, is not the equivalent of saying that "crime is destiny" and that for a given person such behavior may be predestined and inevitable.

It is not crime itself or criminality that is innate; it is certain peculiarities of the central or the autonomic nervous system that react with the environment, with upbringing, and many other environmental factors to increase the probability that a given person would act in a certain antisocial manner. No social determinism is involved in such estimates of probability, and the evidence is now conclusive that some such interactionist view is more in line with the evidence than a purely environmentalistic (or a purely genetic) one.
