In introducing this Special Issue on gangs, we overview the thrust of its papers, demonstrating how they
assist in plugging research gaps from the dearth of psychological attention to gangs. The papers therein
raise important theoretical considerations of group process effects, social identity, and communication
influences in gangs. Also included are empirical examinations of how attitudes to formal organized
crime groups may nurture progang views, how social networks bridge gang divides, the dehumanization
and social dominance association with gang membership, and how membership longevity associates
with gang members’ attitudes to their group. We conclude with theoretical prospects and empirical
vistas for future work. For instance, vitality theory may help explain members’ immersion in gangs,
discursive strategies could explain how youth are enticed into gangs, and examinations of community
and law enforcement attitudes to gangs may provide insight into how oppositional attitudes are
fostered on both sides of the gang divide
