Geoffrey D. Dunning

Geoffrey D. Dunning is an influential American psychologist known for his work in social and personality psychology. He is particularly recognized for his research on self-justification, including the Dunning-Kruger effect, which describes how people with lower ability in a task tend to overestimate their competence. Conversely, those with higher ability may underestimate themselves. Dunning's studies highlight the biases in self-assessment and decision-making, demonstrating how these cognitive errors can impact people's beliefs, perceptions, and behavior in various contexts, from everyday life to professional settings. His contributions enhance our understanding of human psychology and social interactions.
