“…Indeed, Lickel et al found that social categories are perceived to be only moderately entitative, whereas intimacy and task groups (which are typically smaller and involve greater interaction among the members) are perceived to be much more entitative.

Therefore in Study 2 we tested the same hypotheses for intimacy and task groups.…”
