I'm waiting for someone on the forums to say that I was clickbaiting with the title and that the article isn't REALLY about math being tribal even though it's in the title of the article...
To be fair, CNN is really just making a clickbait title. The article even says

Looking through the article, "racism" is never even mentioned in a context that implies that the author actually put it into her book. The only thing remotely similar to that is the line "This cycle falls along racial lines, she argues, given the wealth gap between black and white households." But that's just saying that it affects races differently because of the objective statistics on the different average incomes, not that "math is tribal"
