Traditional Biological versus
Modern Biosocial Theories
• Criminology has been slow to give
credence to biological theories.
• Roots grounded in the social sciences
• Criminology today is interdisciplinary
and recognizes contributions from
many disciplines.

Principles of Biological Theories
• Early biological theorists focused mainly
on physical features and heredity.
• Contemporary biosocial theorists take a
more in-depth look at human biology.
• Major distinction is the emphasis placed
on the interplay between biology and
the social and physical environments.

• Research in 1965 led to concept of
"supermale" with XYY chromosome.
Considered potentially violent
Led to attempted use of chromosome-
based defense in court
• Recent research has concluded that
XYY males are not predictably
aggressive.

behavior.

• Rationalizes labeling, stigmatization of
minorities
• Humans are too different from other
animal species to apply findings from
animal studies to human behavior.

Critique of Early Biological
Theories of Human Behavior
• Disregard the role of free will in human
behavior
• Crime is a social construct and its
meaning varies over time and place.
• Unlikely that any biological feature or
combination of features could explain
the wide variety of crime today
