Why do some people react differently to alcohol than others?

Answer 1

Many of the effects of alcohol are a result of our expectations that it will affect us in certain ways. We learn these beliefs from our social environment. For example, in those societies in which people don't believe that intoxication disinhibits, drunken persons don't do things they wouldn't otherwise do.

Research in the U.S. has found that when males are falsely led to believe that they have been drinking alcohol they tend to become more aggressive. Similarly, they experience greater sexual arousal when watching erotica.
