This book presents reviews of the literature and reports of new findings
from research into biological correlates of criminal behavior. The
chapters are revised versions of talks given by participants in an
Advanced Study Institute sponsored by the North Atlantic Treaty
Organization and held inCastelvecchio Pascoli in September, 1986. It is
our second edited volume on biology and crime. The first book, The
Causes of Cdme; New Biological Apwoaches, was published in 1987. In the
preface to that book we described the regrettable hi. tory of the
paeudobiological research into social problem. conducted by the Social
Darwinists at the turn of the century. We requested that that
unfortunate legacy not inhibit responsible and scientifically sound
investigations of biological and psychological variables in criminology
today. Evidence is mounting that showl that research limited to social
and environmental vadables cannot explain the behavior of the minority
of criminal offenders whose criminal careen begin in adolescence and
develop into recidivistic and violent . . saults on society. Certainly
these offenders are few, but epidemiological studies have found them to
be responsible for an amount of crimes disproportionate to their small
numbers. As few . . 5 % of males commit over 50% of criminal offenses.
Intervention directed at these relatively few individuals could, if
succes. ful, dramatically reduce our growing violent crime rate. The
chapters in our earlier book showed that some biological variables do
relate to this type of chronic offending.
