Alcohol doesn’t make people more attractive, but lowers the drinker’s standards. Alcohol impairs the judgment of the part of the brain that finds a mate, reducing the mental sorting process. Drinking alcohol can also contribute to a change in attractiveness standards.
For someone who is drinking alcohol, other people don’t become more attractive, rather the drinker’s standards lower, research shows. This goes against the popular “beer glasses” phenomenon which claims that alcohol causes the wearer to see other people transformed to appear more desirable. Instead, alcohol is thought to reduce the mental sorting process people normally go through when deciding on a mate. When sober, a person might have a set of criteria they prefer potential mates to meet. When a person is under the influence of alcohol, the part of the brain that is wired to find a mate is still active, but its judgment is impaired.
