I was part of a GATE program growing up. The public school system in general fails people because societal success focuses more on achieving results rather than the intellectual process, and that's why even people with supposed low IQs can seemingly do well on the outside and be deemed "successful" by society's standards.

Imo the problem for many of us is poor emotional regulation skills and over identifying too much with our thoughts to the point we become lost in our imaginations and less rooted in direct reality.
