An extensive poll in New York City, with four groups of interviewers, showed that anti-Semitic views tend to be withheld from interviewers of Jewish appearance or name. Lower educational and economic groups were more influenced by the appearance of the interviewer. Indirect questions reveal less anti-Semitism. It is possible that the lower classes show more anti-Semitism when directly questioned because of a tendency to agree with stereotyped anti-Jewish statements.
