Fascinated by madeinuk's liniked article to IAT and its validity and application. I can't speak to that angle and will explore it more fully to inform myself.
My personal, unscientific opinion about IAT is that it is a useful instrument in promoting openness to others in self-aware, mature adults when considered in private, or in confidential consultation with a professional well versed in diversity.
I think it is also instructive, from a population research lens, to have reliable benchmarks for aggregate social attitudes (anonymized) over time, using reliable instruments and voluntary participation. I can't opine whether IAT is one given my current knowledge.
I am concerned about its use in adolescent populations, particularly where they do not have the maturity or life experience in which to contextualize their views. Moreover, I have grave concerns - in any context, adult or adolescent - with an individual's private results being shared with a group.
