Thesis: ADHD is caused by low-quality educational systems (generally characterized by overcrowded classrooms, boringly repetitive rote learning, inattentive underpaid teachers, etc.) - it's not a result of genetics.
This thesis is supported by these facts: (1) there's no solid objective diagnostic test for ADHD at the biochemical level, and (2) there's no solid genetic determinant of who and who won't come down with ADHD.
This doesn't mean ADHD isn't real, it's just much more likely to be a symptom of societal failure to provide quality education for children than 'an inherent defect'.
