心理学家弗兰克知道,人们倾向于认为穿黑衣服的人更权威、行为更有攻击性。因此,他想知道,是不是仅仅穿上黑色的衣服就能够改变人们的行为方式。幸运的是,研究所需数据是现成的。他查阅了全美橄榄球联盟的数据,将穿黑色球衣的队伍的数据与其他队伍进行比较。他找到了5个队服颜色为黑色的队伍——包括洛杉矾入侵者队、匹兹堡钢铁队和辛辛那提猛虎队等——研究他们在球场上的表现。 Psychologist Frank knows that people tend to think black people are more authoritative and behave more aggressively. Therefore, he wondered if it was possible to change people’s behavior simply by putting on black clothes. Fortunately, the data needed for the study is readily available. He reviewed the NFL data and compared the numbers of teams wearing black jerseys to the rest of the team. He found five team uniforms in black - including the Los Angeles Raiders, the Pittsburgh Steadicam and the Cincinnati Bengals - to study their performance on the pitch.
