Some studies suggest various factors within and beyond an individual's control that affect their self-confidence. Hippel and Trivers propose that people will deceive themselves about their own positive qualities and negative qualities of others so that they can display greater self-confidence than they might otherwise feel, thereby enabling them to advance socially and materially. Others have found that new information about an individual's performance interacts with an individual's prior self-confidence about their ability to perform. If that particular information is negative feedback, this may interact with a negative affective state (low self-confidence) causing the individual to become demoralized, which in turn induces a self-defeating attitude that increases the likelihood of failure in the future more than if they did not lack self-confidence. On the other hand, some also find that self-confidence increases a person's general well-being and one's motivation and therefore often performance. It also increases one's ability to deal with stress and mental health. A meta-analysis of 12 articles found that generally when individuals attribute their success to a stable cause (a matter under their control) they are less likely to be confident about being successful in the future. If an individual attributes their failure to an unstable cause (a factor beyond their control, like a sudden and unexpected storm) they are more likely to be confident about succeeding in the future. Therefore, if an individual believes they and/or others failed to achieve a goal (e.g. give up smoking) because of a factor that was beyond their control, they are more likely to be more self-confident that they can achieve the goal in the future. Whether a person in making a decision seeks out additional sources of information depends on their level of self-confidence specific to that area. As the complexity of a decision increases, a person is more likely to be influenced by another person and seek out additional information. However, people can also be relatively self-confident about what they believe if they consult sources of information that agree with their world views (e.g. New York Times for liberals, Fox News for conservatives), even if they do not know what will happen tomorrow. Several psychologists suggest that people who are self-confident are more willing to examine evidence that both supports and contradicts their attitudes. Meanwhile, people who
