more likely to compare him/herself to someone close to him/her, like a sibling or a best friend, than a stranger. There are different factors in which a person can assume closeness: family, friends, people with similar characteristics, etc. If an individual is not close to a particular person, then it makes sense that he/she will not share in their success or be threatened by their success. At the same time, if the person's performance is low, there is no reason to share the success and increase self-evaluation; there is also no reason to compare him/herself to the other person. Because their performance is low, there is no reason it should raise or lower his/her self-evaluation. According to Tesser's (1988) theory, if a sibling did not do well in his/her game, then there is no reason the individual's self-evaluation will be affected. Closeness and performance can either raise self-evaluation through reflection or lower self-evaluation through comparison. Relevance to self-identity determines whether reflection or comparison will occur. There are many different dimensions that can be important to an individual's self-definition. A self-defining factor is any factor that is personally relevant to your identity. For example, skills in music may be important to one's self-definition, but at the same time, being good in math may not be as important, even if you are skilled at it. Relating to your self-definition, you may consider yourself a musician but not a mathematician, even if you are skilled in both. Relevance assumes that a particular factor that is important to an individual is also important to another person. Relevance can be as simple as a shared dimension which one considers important to who they are. If relevance is high, then one will engage in comparison, but if relevance is low, one will engage in reflection. For example, if athletics is important to a person and that person considers athletics to be an important dimension of his/her self-definition, then when a sibling does well in athletics, the comparison process will take place and his/her self-evaluation will decrease. On the other hand, if athletics is not a dimension he/she uses for self-definition, the reflection process will take place and he/she will celebrate the sibling's success with the sibling; his/her self-evaluation will increase along with the sibling's because he/she is not threatened or challenged by the sibling's athletic capability. Tesser (1988) suggests that people may do things to reduce
