Why do ADHD traits persist despite societal penalties?

From an evolutionary and biological perspective, traits linked to ADHD have persisted because they also come with advantages in certain contexts. Curiosity, novelty seeking, rapid response, creativity, and risk tolerance have historically been useful. Clinicians point out that persistence of these traits suggests they’re part of normal human variation, not errors. Society tends to reward only a narrow range of functioning styles. The persistence of ADHD traits reflects diversity in how brains work, even when systems are unforgiving.
