A quick search showed me Adderal reduces narcissitic traits and increases empathy (yay) and roughly the same search but for meth shows lower empathy and increases aggression. I'm sure there are vast differences in the compounds and the dosing size. There's also a gulf between science committed to "adderall is good" and science asking "why meth bad?" Maybe when cartels fund open science we'll have more balance!?! I'd say this thread is groping for a reason C suite can trend towards being narcissistic or psychotic. I'm sure there's a lot of pressure, and having to make a decision to reduce staff, or build a technology that will make jobs across industries redundant, and the broad effects that has on people's lives could lead to a numbness to those branches of empathy. I've personally known people that moderate their state multiple times a day, stratigizing what street or pharmaceutical drug to take to help them get something done, or to chill out, or be trippy up down or sideways, and they have the bladder issues that go with some of those drug choices to boot. I've known some who take ketamine all day and make code that looks like art and runs like a dream. I don't endorse the method, but I've seen it entwined with logic and beauty!
