At this point, I get the impression that for most (by numbers) of those who believe in a race-$trait correlation, the important thing is not to persuade those who are indifferent but to prove those who strongly assert that there is no such correlation wrong. More often than not, for each desirable trait there is cold hard real-world data that suggests strong correlations between race and particular desirable outcomes that appear related to the trait in question. (Say, in the case of IQ, lifetime income, job prestige etc.) If you believe that this difference in outcomes can be traced to a genetic difference in causative traits, to a first approximation the data does not suggest doing anything (with future technology, maybe, it would suggest a large-scale programme of gene therapy). If you believe that there are no such genetic differences, on the other hand, the data implies that there is a great and particularly morally repugnant defect to society, and justifies extraordinary, often outright punitive (e.g. racial quotas) corrective measures. Currently, as far as policymaking in western societies is concerned, the faction that follows the "no genetic differences => (data => extreme measures are warranted)" reasoning is clearly in charge, if you consider e.g. the recent altercations about racial quotas in school discipline (article for: https://www.nytimes.com/2018/03/18/us/politics/school-discipline-disparities-white-black-students.html https://www.nytimes.com/2018/03/18/us/politics/school-discip... / against: https://www.city-journal.org/html/no-thug-left-behind-14951.html https://www.city-journal.org/html/no-thug-left-behind-14951....). If you read the "against" article, that should make it pretty clear why those who believe in the existence of group differences consider the answer important, if "it's important to not do an unwarranted extreme thing" is not already implied by the term "extreme". In the light of this, it does not seem fair to imply that the only significant societal changes a belief in genetic group differences would imply are ones that are so terrible that anyone would be embarrassed to admit advocating them to you or even themselves.
