How Alcohol Affects Social Behavior and Judgment

Alcohol impairs social judgment by suppressing prefrontal cortex activity, leading to:

• Disinhibition: saying/doing things one would normally suppress
• Emotional lability: exaggerated affect, aggression, or euphoria
• Risk-taking: unsafe sexual behavior, driving, confrontations
• Misinterpretation of social cues: overestimating friendliness, missing threats

These effects erode relationship quality, damage reputation, and increase vulnerability. Chronic misuse compounds social dysfunction.
