Kim, Kyung Kyu, Ae Ri Lee, and Un-Kon Lee. "Impact of anonymity on roles of personal and group identities in online communities." Information & Management 56.1 (2019): 109-121.

This research examines the influence of multiple self-concepts on behavior in anonymous online communities, utilizing data from 1453 users collected via a web survey. The study finds that multiple self-concepts simultaneously affect argument quality by encouraging conformity to group norms, with the private self directly impacting argument quality. Contrary to prior beliefs, online anonymity was found to reduce the influence of group identity on behavior.
