" There is solid evidence for the fact that when women speak more than 30 percent of the time, men perceive them as dominating the conversation; well, similarly, if, say, two women in a row get one of the big annual literary awards, masculine voices start talking about feminist cabals, political correctness, and the decline of fairness in judging. The 30 percent rule is really powerful. If more than one woman out of four or five won the Pulitzer, the PEN/Faulkner, the Booker—if more than one woman in ten were to win the Nobel literature prize—the ensuing masculine furore would devalue and might destroy the prize. Apparently, literary guys can only compete with each other. Put on a genuinely equal competitive footing with women, they get hysterical. "
