The Context-Dependency of Human Behavior

Key Insight

Human behavior is far less consistent across different situations than intuition suggests, challenging the assumption that individuals possess stable character traits regardless of context. A study in the late 1920s by Theodore Newcomb on adolescent boys at a summer camp found that a boy's talkativeness in a specific setting, like at lunch, strongly predicted his talkativeness in the same setting in the future. However, his behavior in that setting offered almost no insight into how he would behave in a different environment, such as during afternoon playtime.

Further research, such as a study on conscientiousness among college students by Walter Mischel, Neil Lutsky, and Philip K. Peake, revealed similar patterns. A student's neatness in assignments or punctuality bore little correlation to other indicators of conscientiousness, like class attendance or the tidiness of their room. This evidence collectively demonstrates that how people behave at any given moment is more influenced by the specific circumstances of their situation than by an 'immutable inner compass' or fixed personality traits.

Despite empirical evidence, people habitually underestimate the significant role context plays in behavior, a cognitive bias known as the 'Fundamental Attribution Error.' This error leads individuals to fixate on stable character traits and overlook situational influences. For example, camp counselors, after observing children's inconsistent behavior throughout a summer, later recalled their overall behavior as highly consistent. Similarly, students gave vastly different evaluations of the same professor, Lee Ross, depending on whether he taught statistics ('cold, rigid') or humanistic psychology ('warmhearted'), yet believed they were seeing his 'real' personality in both cases. This error profoundly compromises the efficacy of job interviews, as interviewers mistakenly interpret a sample of behavior from a specific, artificial setting as a 'hologram' of the entire person.
