Escalation of commitment: a comparison of differences between Mexican and U.S. decision-makers
比较墨西哥和美国决策者在承诺升级倾向上的差异，发现墨西哥被试更易升级承诺且更自信，两国被试在收到下属的坏消息时都会增加投入。
Differences in tendencies toward escalation of commitment are examined in a comparative study of Mexican and US decision-makers. Results show that Mexican subjects were significantly more inclined toward escalation. Mexican subjects also reported significantly greater confidence in their escalatory decisions, and subjects from both countries escalated their commitment when bad news about the investment came from subordinates. Furthermore, Mexican subjects made relatively smaller additional investments when they were personally responsible for the initial investment decision.
