Those who share our musical taste are likely to be regarded as in-group members and will be subject to in-group favoritism according to our self-esteem and how strongly we identify with our fellow music fans

Musical taste, in-group favoritism, and social identity theory: Re-testing the predictions of the self-esteem hypothesis. Adam J Lonsdale. Psychology of Music, February 10, 2020. https://doi.org/10.1177/0305735619899158

Abstract: Musical taste is thought to function as a social “badge” of group membership, contributing to an individual’s sense of social identity. Following from this, social identity theory predicts that individuals should perceive those who share their musical tastes more favorably than those who do not. Social identity theory also asserts that this in-group favoritism is motivated by the need to achieve, maintain, or enhance a positive social identity and self-esteem (i.e., the “self-esteem hypothesis”). The findings of the present study supported both of these predictions. Participants rated fans of their favorite musical style significantly more favorably than fans of their least favorite musical style. The present findings also offer, for the first time, evidence of significant positive correlations between an individual’s self-esteem and the in-group bias shown to those who share their musical tastes. However, significant relationships with in-group identification also indicate that self-esteem is unlikely to be the sole factor responsible for this apparent in-group bias. Together these findings suggest that those who share our musical taste are likely to be regarded as in-group members and will be subject to in-group favoritism according to our self-esteem and how strongly we identify with our fellow music fans.
