What makes me sad is that there are good reasons to throw out information which don't involve denying mathematical truth, yet people, for whatever reason, seem to prefer denial.

What should happen: "I understand that this person has black skin and therefore according to elementary statistics is more likely to be a criminal, but acting on the information would create an unfair double standard that punishes people for crimes they didn't commit, it would help perpetuate a cycle, and it would violate individual human dignity, so I won't."

What actually happens: exactly what parent said. "Oh no! the computer is making uncomfortable findings that we don't like. The computer must be wrong!"

facepalm.
