This part is bullshit though: "higher educated also tend to have higher IQs and better attention to detail." Sure, it was true 50 years ago. Maybe if you select for STEM grads today, it's true. But it's certainly not true for the vast majority of people with college degrees who skate by on diversity quotas and have such a limit grasp on math and reality that they put themselves 100k in debt obtaining these useless degrees. And for anyone that actually read the bullshit study, theyre simple going by bachelors degrees or higher and I think they are specifically selecting k-12 teachers which are typically very average IQ at best.
