Researchers think that people who live for the day and the moment, callous about the consequences of their actions are the ones who are likely to get aggressive when they go overboard with drinks.
'People who focus on the here and now, without thinking about the impact on the future, but the effect is magnified greatly when they're drunk. If you carefully consider the consequences of your actions, it is unlikely getting drunk is going to make you any more aggressive than you usually are. Alcohol makes you 'short-sighted' - it narrows your attention to what is important to you right now. That may be dangerous to someone who already has that tendency to ignore the future consequences of their actions and who is placed in a hostile situation,' said Brad Bushman, lead author of the study and professor of communication and psychology at Ohio State University.
