B. Guerin, USE OF GROUP VIEWS WHEN GIVING OPINIONS ABOUT UNKNOWN, GROUP-SALIENT,OR NEUTRAL ITEMS, The Journal of social psychology, 135(1), 1995, pp. 57-61
Ninety-one university students and 86 nonstudents answered a questionn
aire about their opinions on unknown, pro-student, and neutral items.
The participants agreed with the presumed opinion of their own groups
for unknown items and pro-student items, but not for neutral items. Th
e fact that the participants used the (presumed) group opinion for unk
nown items is consistent with Moscovici's (1984) proposal that social
representations make the unfamiliar familiar acid that, lacking other
grounds, people anchor their beliefs in the beliefs of similar others.
