Women may improve decision-making partly because they rein in a male penchant for overconfidence and risk-taking. One study found that men trade stocks 45 percent more than women do, actually reducing their returns by 2.7 percentage points per year.
女性也许能改善决策的一部分原因是,她们会收敛男性对过分自信与冒险的偏好。一项研究发现,男性买卖股票的频率高出女性45%,实际上却让他们的收益每年减少了2.7个百分点。
Other researchers found that the testosterone level in the saliva of male financial traders predicted profits earned that day, because risk-taking often earns more profits. But when things go bad, the result is a spectacular crash. I’ve noted that Lehman Brothers might have been better off with more female executives, but the optimal arrangement wouldn’t have been Lehman Sisters but rather Lehman Brothers and Sisters.
其他一些研究人员发现,男性金融交易员唾液中的睾丸酮水平预示了当天的盈利情况,因为冒险通常会带来更多的利润。但当形势恶化时,结果惨不忍睹。我说过,如果女性高管再多一些,雷曼兄弟(Lehman Brothers)的情况可能会更好一些,不过最理想的安排不是雷曼姐妹,而是雷曼兄弟姐妹。
Higher education is another area where women have made huge inroads, despite early hostility from men.
高等教育是女性取得进展的另一个领域,尽管早期受到了男性的敌视。
