Juvenile Crime: When Should Juveniles
Be Treated as Adults?
BY LAURENCE STEINBERG, PH.D. AND ELiZABETH CAUFFMAN, PH.D.*

EBATES OVER how society should respond to seri-
ous juvenile crime can be framed from many vantage
points. Within a moral framework, one might very
reasonably raise questions about fairness and justice, and
probe whether treating juvenile crime in a particular way
strikes an acceptable balance between the rights of the
offender, the interests of the offended, and the concerns of
the community. Within a legal framework, the discussion
might focus on the ways in which a given approach to juve-
nile crime fits within the broader compass of the law, and on
the logic of the legal analysis that undergirds the proposed
policy. From apolitical perspective, deciding how to respond
to serious juvenile crime raises an entirely different set of
concerns: What does the larger community want to accom-
plish, what sorts of social and legal policies might achieve
these goals, which of the inevitable trade-offs are acceptable,
and what are politicians willing to do to satisfy their con-
stituents? And from a practical point of view, one might raise
questions about the short- and long-term consequences of
one set of policies versus another. Does a given approach to
juvenile crime strike a satisfactory balance among the com-
munity's legitimate, but often conflicting, interests in public
safety, retribution, deterrence, and rehabilitation?
Regardless of the perspective one uses to examine the
issues, the fact that juvenile crimes-even very serious and
very violent crimes-are committed by individuals who are
not adults adds an element to the discussion that cannot be
ignored. The moral, legal, political, and practical concerns
that one brings to the table for a discussion of juvenile
crime may be very different from those that are raised in a
discussion of adult crime, simply because of the develop-
mental status of the offender. A fair punishment for an adult
may seem unfair when applied to a child who may not have
understood the consequences of his actions. The ways we
interpret and apply laws may rightfully vary when the spe-
cific case at hand involves a defendant whose understand-
ing of the law is limited by immaturity. The practical and
political implications of sanctioning offenders in a particu-

lar fashion may be very different when the offender is young
than when he is an adult
The purpose of this article is to add the perspective of
developmental psychology to the current debate about the
appropriateness of transferring serious juvenile offenders to
adult court. Generally speaking, a developmental perspective
examines the soundness of age-based legal policies in light of
scientific research and theory on psychological development.
It asks whether the distinctions we draw between people of
different ages under the law are sensible in light of what we
know about age differences in legally-relevant aspects of
intellectual, emotional, or social functioning.
Our primary task in the pages that follow is to examine
the evidence on the development of legally-relevant compe-
tencies, capacities, and capabilities and to suggest whether,
on the basis of what we know about development, a juris-
dictional boundary should be drawn between juveniles and
adults, and if so, at what age it should be drawn. Although
we shall indirectly address whether considerations of public
safety, deterrence, and retribution are so compelling that
they outweigh any claims that can be made on the basis of
observed differences between adolescents and adults, a
direct examination of this issue does not fall squarely within
the bailiwick of developmental psychology. It is crucial to
ask whether transferring juveniles to the adult criminal jus-
tice system in fact makes for more effective deterrence,
community safety, or public confidence in the fairness of the
legal system, and it is even more important to ask whether
these goals are more worthwhile than preserving the legal
distinction between juveniles and adults because of differ-
ences in their developmental status. Although a develop-
mental perspective can inform the discussion of these moral,
political, and practical questions, it cannot answer them.
The Science of Developmental Psychology
Developmental psychology, broadly defined, concerns
the scientific study of changes in physical, intellectual, emo-
tional, and social development over the life cycle.
Developmental psychologists are mainly interested in the
study of normative development (i.e., patterns of behav-
ior, cognition, and emotion that are regular and predictable
within the vast majority of the population of individuals of
a given chronological age), but they are also interested in
understanding normal individual differences in develop-
ment (i.e., common variations within the range of what is
