RT Article T1 Ambiguity and legal compliance JF Criminology & public policy VO 20 IS 4 SP 621 OP 643 A1 Barnum, Timothy C. A2 Nagin, Daniel 1948- LA English YR 2021 UL https://krimdok.uni-tuebingen.de/Record/1796285412 AB This study examines the independent and joint effect of ambiguity and perceived certainty of apprehension on law-breaking decision-making. Data come from a survey of experienced drivers (N = 1147) who viewed videos depicting a car speeding on an interstate highway under experimentally manipulated circumstances. The sampled drivers were generally ambiguity averse, opting to reduce speeding as ambiguity about the perceived certainty of apprehension increased. However, perceived ambiguity interacted with perceived certainty such that increases in ambiguity increased the deterrent effect of ambiguity for low certainty probabilities and decreased the effect for high probabilities.
