A key principle of individual differences research is that biological and environmental factors jointly influence personality and psychopathology. Genes and environments interact to influence the emergence and stability of both normal and abnormal behavior, including by shaping the neural circuits underpinning behavior. In a recent review, we evaluated the question of whether it is possible, not only to differentiate a person from their psychological problems, but also to differentiate the person from their psychological problems and their environment. We provided recommendations for future research to better inform our ability to study personality and psychopathology, while separating the influence of environment.
