"The predictor is probably not biased against any particular race - the race_factorAfrican-American:score_factorHigh term is not statistically significant. Or, as ProPublica puts it, it's "almost statistically significant"."
I don't think you can conclude that the predictor is probably not biased against any particular race -- you can only use significance to reject the null hypothesis, not prove the null hypothesis (especially since the significance is still somewhat high). Am I misunderstanding the claim in the article?
