The students who are most willing to acquiesce in the suppression of civil liberties are also those who are most likely to be prejudiced against minority groups, to be conformist and traditionalistic in general social attitudes, and to lack a basic faith in people.

This finding is consistent also with the fact that student leaders are more likely to be supporters of the values implicit in civil liberties than the other students.

In this sense also, they are surely conformists.
