Social Assortment

Humans organize social life within large-scale and complex systems of social groups. Defining oneself both as individual and as a belonging member to a group is an important feature of humans’ psychology. In inter-group contexts humans demonstrate a systematic tendency to favor and copy members of their own group (the in-group) over a different group (the out-group). Thus creating similarities in e.g. appearance or behavior among (in)group members, while at the same time, stabilizing contrast and distance towards out-groups.

Often such social groups are large, including mainly complete strangers. Hence the aforementioned similarities can serve as markers (or tags) to identify strangers as in-group members. Such tags can appear in different forms including skin-color, languages and accents as well as flags, badges and hairstyles. We are interested in children’s developing perception and use of group tags and the cross-cultural variation of tag-based social assortment.
