Alcohol’s Dulling Effect: Why You Might Act More Aggressively After a Drink
While alcohol might loosen inhibitions and make you feel more carefree, new research reveals a darker side to that feeling of numbness. It could be fueling aggression.
A recent study conducted by Ohio State University suggests a direct link between alcohol consumption, increased pain tolerance, and a heightened willingness to inflict pain on others.
"We’ve all heard the saying ‘I feel your pain,’" noted study co-author Brad Bushman, a professor of communication at OSU. "But when intoxicated individuals experience a decreased sensitivity to pain, they may be less likely to empathize with the pain of others, potentially leading to more aggressive behavior."
The study involved over 800 participants, all classified as regular drinkers. After consuming either an alcoholic beverage or a placebo, they were subjected to a series of electric shocks, gradually increasing in intensity. The researchers identified each participant’s “pain threshold” – the point at which they felt the shock as painful.
Following this, participants engaged in a competitive online game where they could deliver electric shocks to a simulated opponent. Predictably, those who consumed alcohol displayed a higher pain threshold and, startlingly, were more inclined to administer stronger and longer shocks to their opponents than those who hadn’t drunk alcohol.
"Those consuming alcohol seemed less bothered by the electric shocks themselves and were more willing to inflict discomfort on others," Bushman explained.
The study even noted that the participants’ level of aggression connected directly to their pain tolerance. Those with a higher pain threshold due to alcohol were significantly more aggressive.
While the study participants had blood alcohol levels slightly above the legal limit, researchers suggested that even higher levels of intoxication could further amplify this aggressive behavior.
"This research sheds light on one possible reason why intoxicated individuals might be more prone to violence," summed up Bushman. "Understanding this connection between alcohol, pain tolerance, and aggression can be valuable in addressing alcohol-related violence."
This research provides an important reminder that moderate to heavy drinking can have significant consequences beyond simple intoxication. It highlights the need for responsible drinking habits and fosters a better understanding of the often-hidden psychological effects of alcohol.
