Criminal propensity theorists argue that the causes of variation in of
fending behavior can be traced to variation in one or more causal trai
ts. Other theorists contend that there is actually more than one type
of offender and that more than one causal mechanism operates to explai
n offending behavior. In this article, some of the implications of the
se two positions are considered. Then, their congruence with recidivis
m data from a cohort of post-age-16 North Carolina institutional relea
sees (N = 848) is assessed. The analysis focuses specifically on wheth
er the correlates of offending persistence are similar across two cate
gories of individuals: those who experienced their first adjudication
at an early age and those who were first adjudicated at a later age. I
n support of both positions, some similarities and some differences in
the correlates of persistence were discovered. The differences, howev
er, were only evident when the threshold for late first adjudication w
as set to age 12. When this threshold was raised to higher ages, the d
ifferences disappeared.
