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.

Early Biological Theories
• Built on scientific tradition of positivism
• Positivism
 Associated with the belief that all valid
knowledge is acquired only through
observation
• Key principles
 Social determinism
 Application of scientific techniques to
the study of crime

All Rights Reserved

Physical Features and Crime
• Phrenology
 The study of the shape of the head to
determine anatomical correlates of
human behavior
 Franz Joseph Gall located the roots of
personality in the brain.
 Johann Gaspar Spurzheim brought
phrenology to the U.S.

The Italian School
• Cesare Lombroso
 Atavism
• Criminality is the result of primitive urges
that survived the evolutionary process.
 Stigmata of degeneration – physical
features indicative of criminality

The Italian School
• Lombroso's work contributed to field of
criminal anthropology.
 Scientific study of relationship between
physical characteristics and criminality

All Rights Reserved
Frank Schmalleger
The Italian School
• Lombroso's categories of offenders
 Atavists, or born criminals
 Insane
 Criminaloids
• "Occasional criminals" led into crime by
environmental influences
 Criminal incited by passion

All Rights Reserved

The Italian School
• Masculinity hypothesis
 Criminal women exhibited masculine
features and mannerisms.

Evaluations of Atavism
• Charles Buckman Goring
 Failed to find support for thesis of
atavism
• Earnest A. Hooton
 Criminals are physiologically inferior to
the general population.

All Rights Reserved
Frank Schmalleger
Evaluations of Atavism
• Canadian study (2000) found subtle
physical abnormalities were associated
with an increased risk of behavioral and
psychiatric problems among boys.

Constitutional Theories
• Explain criminality by reference to:
 Offenders' body types
 Genetics
 External, observable physical
characteristics

All Rights Reserved
Frank Schmalleger
Constitutional Theories
• Ernst Kretschmer
 Proposed relationship between body
build and personality type
• William H. Sheldon
 Endomorph
 Mesomorph
 Ectomorph

Criminal Families
• Sir Francis Galton
 Systematic study of heredity
contributed to field of behavioral
genetics
• Criminal families
 The Juke family
• Richard L. Dugdale
 The Kallikak family
• Henry H. Goddard

All Rights Reserved

Criminal Families
• Eugenic criminology
 Root causes of criminality were passed
down in the form of "bad genes."
• Genetic determinism
 Genes are the major determining factor
in human behavior.
• Buck v. Bell (1927)
 Supported Virginia statute permitting
sterilization

The XYY Supermale
• 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.

Twin Studies and Heredity
• Twin studies compare MZ and DZ twins
to examine role of heredity in crime
causation.
• Research supports relationship between
heredity and risk of criminality.
• Minnesota Twin Family Study found MZ
twins reared apart are about as similar
as those reared together.

Biological Roots of Human
Aggression
• Konrad Lorenz
 On Aggression (1966)
 Human aggression serves other
purposes but takes on covert forms
(drive to acquire wealth and power).
 Human behavior is adapted instinctive
behavior.

All Rights Reserved

Sociobiology: The New Synthesis
• Introduced by Edward O. Wilson in
1975
• Systematic study of the biological basis
of all social behavior
• A new paradigm in criminological
theories
 Brought renewed attention to biological
theories in social sciences

All Rights Reserved
Frank Schmalleger
• The main determinant of behavior is
the need to ensure the survival and
continuity of genetic material
throughout generations.
• Altruism facilitates the continuity of the
gene pool.

All Rights Reserved
Frank Schmalleger
Criticisms of Sociobiology
• Fails to consider significance of culture,
social learning, individual experiences
• Fundamentally wrong in its depiction of
basic human nature
• Rationalizes labeling, stigmatization of
minorities
• Humans are too different from other
animal species to apply findings from
animal studies to human behavior.

All Rights Reserved
Frank Schmalleger
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
