The Data on Bar Fights

What happens when a fight breaks out at a bar? A Penn State sociologist gathered data from nightlife venues in Toronto to find out. From BPS Research Digest

Michael Parks and his colleagues trained dozens of observers who analyzed 860 aggressive incidents across 503 nights in 87 large clubs and bars in Toronto, Canada. Aggression was defined as anything from a verbal insult or unwanted physical contact to a punch or kick. Incidents were twice as likely to involve one-sided aggression as opposed to mutual aggression. The most common incident involved a man making persistent unwanted overtures or physical contact towards a female. Male on male aggression was the next most frequent category. All-female aggression was rare.

Third parties intervened in almost one third of these situations, and they were more than twice as likely to intervene in a non-aggressive way than to be aggressive themselves. Eighty per cent of third parties who got involved were men. Drunk third parties were more likely to be aggressive. Surprisingly perhaps, the most frequent kind of aggressive incident (male on female) was the least likely to provoke third party involvement. One-sided aggression between men also provoked few interventions. Parks and his team think this is probably because such incidents are judged to be non-serious and unlikely to escalate.
