Simply criminal: predicting burglars' occupancy decisions with a simple heuristic

Area of Science:

• Criminology
• Cognitive Psychology
• Behavioral Economics

Background:

• Rational choice theories posit offenders integrate multiple cues (compensatory strategy).
• This study challenges the assumption of compensatory decision-making in criminal behavior.

Purpose of the Study:

• To compare the predictive accuracy of a compensatory strategy (Franklin's Rule) versus a non-compensatory strategy (Matching Heuristic) in burglars' residence occupancy decisions.
• To examine the correspondence between burglars' cue utilization and the ecological validity of those cues.

Main Methods:

• Forty burglars evaluated 20 residence photographs each, deciding on occupancy.
• Participants provided open-ended cue reports and rated cue importance.
• Decision policies were compared against actual occupancy and cue validities.

Main Results:

• Burglars predicted occupancy above chance levels.
• The Matching Heuristic significantly outperformed Franklin's Rule in predicting decisions.
• Cue use in the Matching Heuristic aligned better with environmental cue validities.

Conclusions:

• Findings support a limited rationality model of criminal decision-making.
• The most important cue for burglars (vehicle presence) was also the most ecologically valid.
• Open-ended reporting better captured self-reported cue use than rating methods, with implications for crime prevention strategies.
