Don’t underestimate under-diagnosis. Over the last century the number of people who are left handed rose from ~4% to ~12%. What happened? We stopped punishing children for writing left handed and forcing them to write right handed. We like to blame this like autism and ADHD on emotional factors like screen time. Maybe there’s some truth to that. But I firmly believe that a lot of neurodivergence can be explained by better diagnosis and less punishment.
