Is that really even a fallacy? In medicine, they infer your risk for certain diseases based on age, race, gender, lifestyle habits etc. Individual risk varies

Is that really even a fallacy? In medicine, they infer your risk for certain diseases based on age, race, gender, lifestyle habits etc. Individual risk varies of course, but that doesn't mean that generalization is wholesale a bankrupt concept. He never says group traits == individual traits, he states 15x "on average." Yes, there's Simpson's paradox as described in your citation, but that doesn't mean averages, sigmas are useless as a whole. They have to be applied carefully, which Kaufman addresses.
