Protesters urge Egyptian president Hosni Mubarak to leave office
By Kevin R. Betts
Looking at recent news events, it seems apparent that acts of aggression often involve groups. For the past two weeks in Egypt, thousands of anti-government protesters have maintained control over Tahrir Square demanding that their president step down from power. On a flight this weekend from the Canary Islands to Belgium, dozens of passengers became so enraged about oversized baggage fees that law enforcement officers were called to the scene. In Ohio, two men shot into a Youngstown State University fraternity house this weekend, later claiming that they were angry about being ejected from a party. These recent events suggest that group contexts might promote aggressive behavior. But what exactly is it about groups that promotes aggression?
Meier, Hinsz, and Heimerdinger (2007) present a framework for explaining aggression involving groups. They suggest that given a competitive or aggressive context, groups can be expected to react more aggressively than similarly treated individuals. This is because group contexts contain situational elements that stimulate their members to act aggressively. For example, hostile cognitions and negative affect are known to promote aggression among individuals. It is probably easy for most of us to imagine instances in our own lives where provocation (hostile cognitions) or a bad mood (negative affect) led us to act aggressively. Meier et al. (2007) suggest that in group contexts, both hostile cognitions and negative affect are more likely to emerge and therefore promote aggressive reactions. Disinhibition, or the loss of one’s individuality, self-awareness, or self-evaluation apprehension, is another mechanism that might promote aggression in groups. There are many situational factors that promote disinhibition, and thus aggression, among individuals (e.g., alcohol). Meier et al. (2007) suggest that group contexts on their own may promote disinhibition among their members, which might release social constraints against aggression. The researchers identify other situational variables that might influence aggression in groups as well, including group accentuation, arousal, and individual differences.
The framework presented by Meier et al. (2007) supports the notion that groups are more likely than individuals to react aggressively given a competitive or aggressive context, and identifies situational elements that promote aggression among groups. Readers may be able to detect the influence of these situational elements in their own lives. Hostile cognitions, negative affect, disinhibition, and other factors likely influenced the protestors in Egypt, the passengers angry over baggage fees, and the shooters at Youngstown State University. Can you think of a time when these factors influenced you or someone you know to act aggressively in a group?
