Well, the people who use skin colour as evidence, i would guess, are on average less well behaved than rest of society… so you can use it to guess someone’s criminality or other untrustworthiness.
You have the neonazis among those who use skin colour as evidence of criminality, but not among those who don’t. I don’t know of other differences that were demonstrated, my expectation for other effects is zero. I should expect the overall effect on order of at least the proportion of race motivated violence to overall violence; my expectation is somewhat higher than this though because I would guess that the near-neonazis are likewise more violent, including within-race crime.
What sort of effect size do you expect here? Why?
