The aim of the current study was to examine the repeat residential burglars’ target selection behaviors. The data consisted of variables relating to target selection behaviors and decision making of 104 serial residential burglars, who had arrest records for residential burglaries in the past. The results of multiple correspondence analysis revealed that residential burglars’ target selection behaviors could be differentiated into three styles: “burgling in the absence of residents”, “burgling in the presence of residents while they are sleeping at night”, and “burgling of mixed styles”. Among 14 variables relating to burglars’ decision making while committing crimes, three factors (risk/reward-oriented, traceless entry-oriented, low effort area-oriented) were extracted by exploratory factor analysis. The level of burgling skill evaluated by the suspect interviewers positively correlated with a factor score of the “risk/reward-oriented” factor (ρ = .20, p < .05) but negatively correlated with a factor score of the “low effort area-oriented” factor (ρ = –.24, p < .05). These results suggest that repeat residential burglars are rational decision makers, but the way they are rational varies.
