The Psychology Of Lying

About Course

This intermediate course explores the multifaceted nature of lying through the lens of psychology, neuroscience, and behavioral science. You will examine why humans lie, how deception develops across the lifespan, the neurological underpinnings of dishonesty, and the social implications of lying in various contexts.
