Which factor best explains the link between alcohol consumption and violent behavior, according to the evidence?

• A. Disinhibition from pharmacological effects
• B. Cultural norms, not pharmacological effects
• C. Cognitive guidedness
• D. Unknown factors

Answer: (B)

The strongest explanation in the evidence is that cultural norms and social expectations around drinking and aggression shape when alcohol is linked to violent behavior. While alcohol can cause physiological disinhibition, how often violence occurs after drinking depends a lot on the social script people are following in a given context—what behaviors are considered acceptable when intoxicated, who is seen as allowed to act aggressively, and how peers and institutions respond to drunkenness. In settings where norms condemn violence and drinking is tied to sociable, non-aggressive behavior, intoxication does not reliably lead to violence. Conversely, in environments where aggressive behavior is tolerated or even expected when people are drunk, violence after drinking is more likely. Experimental and real-world studies also show expectancy effects: people who believe they have consumed alcohol may display more aggressive tendencies even if they did not actually ingest alcohol, highlighting the power of norms and beliefs alongside pharmacology. So, although disinhibition from pharmacological effects plays a role, the evidence best supports cultural norms as the key factor driving the alcohol–violence link.
