Abstract: | We examined the decision strategies and cue use of experts and novices in a consequential domain: crime. Three participant
groups decided which of two residential properties was more likely to be burgled, on the basis of eight cues such as location
of the property. The two expert groups were experienced burglars and police officers, and the novice group was composed of
graduate students. We found that experts’ choices were best predicted by a lexicographic heuristic strategy called take-the-best
that implies noncompensatory information processing, whereas novices’ choices were best predicted by a weighted additive linear
strategy that implies compensatory processing. The two expert groups, however, differed in the cues they considered important
in making their choices, and the police officers were actually more similar to novices in this regard. These findings extend
the literature on judgment, decision making, and expertise, and have implications for criminal justice policy. |
