Answer to Question 1
There is evidence that there are corrupting aspects of power. Evidence suggests that power leads people to place their own interests ahead of others. Why does this happen? Interestingly, research suggests that power not only leads people to focus on their self-interests because they can, it also liberates people to focus inward and thus come to place greater weight on their goals and interests. Power also appears to lead individuals to objectify others, to value relations with people with less power, and to see relationships as more peripheral. Powerful people react especially negatively to any threats to their competence. They're more willing to denigrate others. People given power are more likely to make self-interested decisions when faced with moral hazard. Power also leads to overconfident decision making.
Answer to Question 2
The common belief is that women are more emotional than are men. Evidence confirms that women are more emotionally expressive than are men, they experience emotions more intensely, and they tend to hold onto emotions longer than men. They also display more frequent expressions of both positive and negative emotions, except anger. Evidence from a study of participants from 37 different countries found that men consistently report higher levels of powerful emotions like anger, whereas women report more powerless emotions like sadness and fear. Thus, there are some sex differences in the experience and expression of emotions.
