The ones that agree have found that women on average believe they are able to successfully do tasks less than men. When they do succeed they think it is because of external (not relating to them directly) causes, like luck. When they fail, women think it is because they do not have the necessary abilities. With men, it is the opposite case. When they succeed, they think it is because of internal (directly related to them) causes like being smart and their abilities. However, when they fail they blame it on bad luck or the task being too hard.
