Beer goggles are stunningly real, and you should know how to avoid them.

The researchers found that while sober people are distracted by attractive faces, drunk people are distracted by, well, any face. To learn this, the researchers had drinkers complete a task while showing them attractive and unattractive faces and tracking their attention. (The "stimuli" were photographs of forward-facing faces from a research database.) Key finding: Even very mildly intoxicated drinkers give their attentions to fugly faces. "This suggests that it doesn't take much for people to put on their beer goggles," says coauthor Derek Helm, a psychologist at Edge Hill University.
