People often make judgments about a group (e.g., immigrants from a specific country) based on information about a single group member. We found in six studies (N = 1,220) that people expect the performance of an arbitrarily ordered group to match that of the group member in the first position more closely than that of group members in other positions (e.g., middle or last). We show this pattern of judgment for groups in various performance contexts (e.g., cooking contest, relay race, academic test), and whether the focal member performs poorly or well (Studies 1-2). We term this effect the “first-member heuristic,” and show that it occurs because the first (vs. middle or last) member is seen as more diagnostic of the rest of the group (Study 3)—that is, more informative for drawing inferences about the group. Furthermore, we show that the first-member heuristic has downstream behavioural consequences for people’s willingness to bet on a group’s success (Study 4), support policies that would benefit or hurt the group (Study 5), and join the group (Study 6).
