Eh, if it gives the effects described in the grandparent on a consistent basis and I happen to have ADHD, I would gladly trade off the very low expected cost of my soul (since I have a very low P on it existing in the first place) for the large increase in mental superpowers.
Remember that the "soul" you are giving up isn't really the Cartesian dualist version. It matches better to certain emotional or social states that many people prefer to experience.
I've long had attention and focus problems, but never explored the possibility that I have ADHD till recently. I understand that it's a standard term, but I'm still a bit suspicious; Psychiatry doesn't seem like the most reliable field.
Are there good reasons for picking out the behaviors associated with ADHD and giving them a name? Obviously this is a different question than whether ADHD is a 'disorder' or 'disease', and whether ADHD medication is good or bad for people.
Answers that would satisfy me
