Miss Barnett, presenting a study of anger and the sexes to a British Psychological Society conference, said that she had looked at how levels of fury changed over the years. She questioned 153 people about issues that angered them. At the bottom end they would be “not very angry”, rising at the top of the scale to “very, very angry”. To her surprise, rather than follow the stereotype of male anger and reasonable female calm the women showed themselves to be far crosser than men. Once organised into age brackets it became clear that although men and women showed the same levels of anger aged 18 to 25, their responses sharply diverged as they aged. By the time they are heading for their 40th birthday men are far less easily angered and the downward trend continues. Women’s anger levels remain the same throughout their lives and by the time they collect their pensions they are as aerated as the day they began their careers.
