We research the cognitive processes underlying diagnostic errors. It is often thought that systematic reasoning errors (called biases), which arise due to fast reasoning, are an important cause of diagnostic errors. However, there is also evidence that fast reasoning is an vital part of the diagnostic reasoning process, which often leads physicians to correct diagnoses. Using reaction times and eye movements, we study to what extent fast and slow reasoning is related to diagnostic errors. Furthermore, we study cognitive reasoning tools (such as checklists) and feedback interventions as interventions to reduce diagnostic errors.
