This study uses data from the second and third waves of the National Y
outh Survey to examine the effect of neutralizations regarding violenc
e on violent behavior. Data indicate that only a small percentage of a
dolescents generally approve of violence or express indifference to vi
olence. A large percentage of adolescents, however, accept neutralizat
ions justifying the use of violence in particular situations. Both cro
ss-sectional and longitudinal data suggest that the acceptance of thes
e neutralizations contributes to violent behavior. Further, the effect
of these neutralizations on violence is conditioned by certain variab
les; neutralization is most likely to lead to violent behavior among t
hose who disapprove of violence and associate with delinquent peers.
