right, you can look at raven progressive matrices/ advanced progressive matrices. there's no language or other cultural knowledge required. it's just shapes and picking the shapes that go in the blank.  and blacks still dramatically underperform. at that point you get to making absurd arguments like "well ok but maybe these people don't understand the concept of paper and a pencil being used for circling the correct answer or the idea that they're actually supposed to answer the question correctly, or there is an answer. think about those cultural assumptions!" and the response is "yeah but consider the alternative hypothesis where they're just fucking dumb and you're mega coping to literally any argument and maybe we get to the point where not being able to give answers to questions kind of makes you dumb."
