From a college yearbook, 26 photos were selected to represent a range from extremely Jewish to non-Jewish-looking. 685 Harvard and Radcliffe students were asked to identify the Jewish photos, indicating certainty and the cues utilized. Persons high in anti-Semitism (on the Allport-Kramer scale) identified Jewish faces more accurately and with more confidence, but did not report the use of more cues. They also reported less equal-status and general contact with Jews. A correlation of .55 between anti-Semitism and Catholic-Negro prejudice is interpreted as general bigotry of prejudiced persons, whose feeling of threat arouses vigilance or sensitivity to ethnic characteristics. 17 references.
