Although prior studies on robbery decision making have explored how offenders manipulate fear in the coercive process, research has paid little attention to the issue as it relates to carjacking. The gap is significant given that carjacking requires offenders to neutralize victims who are inherently mobile and who can use their vehicles as both weapons and shields. Based on qualitative interviews with 24 active carjackers, the present paper explores this issue and the data’s grounded-theoretic significance for coercive decision making in predatory social exchange. In particular, the article examines fear as an essential intervening variable that links threat to compliance. It also explores how offenders manipulate the "severity" dimension of threat to influence the certainty and celerity of compliance. The approach taken here offers an advancement in the study of coercion and a refinement of the compliance generation process itself.
