The best data we have suggests that, overall, we are getting angrier. Last year, 22% of respondents around the world told the Gallup organisation they felt angry, a record since the question was first asked in 2006. And something else, even harder to measure, feels like it's different as well：it's as though our anger has curdled, gone rancid. As a society, we seem not to express it and move on, but to stew in it-until, at the extremes, it hardens into violence and hate.

Because the effects of anger are sometimes so appalling, it's easy to conclude that anger is inherently bad in itself-with occasional exceptions, perhaps, for major social transformations,like the fight for women's suffrage, or the US civil rights movement. But studies have consistently shown that even everyday anger-not campaigns against injustice, but snappy remarks over the dinner table-usually has positive results. Pioneering work in the 1970s by the American researcher James Averill, confirmed in the years since, found that nonviolent expressions of anger generally helped people understand eachother better, and to cooperate more successfully.

In evolutionary terms, this makes sense. An emotion as widespread and ancient as anger doesn't persist by accident, but serves a clear purpose：to protect boundaries, deter threats, and make it a less appealing prospect to injure or exploit you-to make the target of anger“less willing to-impose costs and more, willing to tolerate costs”, in the words of the psychologist Aaron Sell It provides a feeling of control, and the motivation to take the necessary actions in order to assert that control-as when it helps a shouty teenager negotiate more freedom from his parents.

But the crucial point about these positive sides is that there was an obvious route for translating anger into action, and thus reaching resolution. By contrast, we've built a world that's extremely good at generating causes for anger, but extremely bad at giving us anything constructive to do with it.

We face big, systemic forces that threaten our well-being-automation, globalisation and above all climate change-but that offer few ways for individual people or communities to turn their anger into change. Incidentally, this also explains why “venting” your anger, by punching a pillow or suchlike, doesn't work, and can even make things worse. That old advice is based on the assumption that emotions simply need release. But anger isn't trapped wind. It doesn't need somewhere to go. It needs something to do.
