The paper explores the relationships between individual differences in intelligence and personality, and the ability to extract critical information (and identify missing but required information) from a suspect’s brief sheet (i.e., model formulation) and develop a suitable line of questioning (i.e., approach strategizing) in interrogation scenarios. We hypothesized that cognitive flexibility, emotion management, low need for closure, and rapport would all be predictors of these abilities. Two hundred and seventy four participants of different backgrounds were exposed to two interrogation scenarios to assess model formation and approach strategizing abilities, as well as intelligence and personality tests. Benchmarks for performance were measured against two experienced interrogators and two psychologists’ calibrated performance. In terms of overall performance, only rapport and cognitive flexibility were significant positive predictors. Whereas only rapport was a positive predictor of approach strategizing, both rapport and cognitive flexibility were positive predictors of model formation. In conclusion, the data from the early stage of our project suggests that the examined factors should be carefully considered when training and selecting optimal interrogators. Though previous research has identified a number of individual differences in intelligence and personality that are important in demanding law-enforcement contexts, ours is the first to explore them with respect to effective interrogator performance.
