People’s responses to race-related polls are heavily influenced by the race of the interviewer (2018 GSS)

Was digging around General Social Survey data when I noticed that they had a column for the race of the interviewer and had an idea. Turns out the race of the interviewer has a huge impact on people's responses to race-related questions, especially white people. Seems like a pretty important finding that everyone who works in opinion polling should be thinking about all the time (maybe they are? But this is the first time I've learned about it), but since I don't know any of them I'll have to settle for telling Reddit.

The data is from the 2018 General Social Survey. The full wording of the questions:

Question 1:

Do you agree strongly, agree somewhat, neither agree nor disagree, disagree somewhat, or disagree strongly with the following statement (HAND CARD TO RESPONDENT): Irish, Italians, Jewish and many other minorities overcame prejudice and worked their way up. Blacks should do the same without special favors.

Question 2:

Some people say that because of past discrimination, blacks should be given preference in hiring and promotion. Others say that such preference in hiring and promotion of blacks is wrong because it discriminates against whites. What about your opinion -- are you for or against preferential hiring and promotion of blacks? IF FAVORS: A. Do you favor preference in hiring and promotion strongly or not strongly? IF OPPOSES: B. Do you oppose preference in hiring and promotion strongly or not strongly?

This is interesting but would be a better fit for the culture war thread. Please repost there.
