One could do multi-level model with interviewers, yeah. Or simpler, regress out interviewer race effects (if any).

Also, it’s quite possible the effect may not replicate. I’d like to see it in a larger mono-ethinic sample that also has independent raters.
Twins also would be a plus to check for genetic overlap of any correlations.
