The intuitive detection theorist (IDT) model of trust posits that trust in hazard managers stems from judgments about their performance on three criteria: their ability to discriminate safe from dangerous situations (discrimination ability); their tendency under uncertainty to assume danger is present (response bias); and their propensity to be open and honest with the public about events (communication bias). The current article tests the model's robustness using findings from three experiments and four surveys conducted by two different research teams. Study-specific analyses and an overall analysis of the seven studies combined confirm that all three of the IDT model's dimensions are important for trust, explaining on average 43% of trust variance. These effects occurred largely independently of hazard topic, research method, or investigator. Hypothesized interaction effects among the dimensions, based upon earlier studies, were weak and contradictory; this is the first known study of interactions among trust model variables.
