Lady Macbeth Effect

Clinical and Motivational Phenomena

The Lady Macbeth effect is a psychological phenomenon in which feelings of shame or moral guilt increase a person's desire to engage in physical cleansing or hygiene-related behavior. It takes its name from Shakespeare's Lady Macbeth, who compulsively washes her hands after helping orchestrate a murder. Researchers who introduced the concept in 2006 found experimentally that people who recalled an unethical act showed a stronger preference for cleaning-related words and were more likely to actually wash themselves afterward.
