...so what if some, a lot, or all CEOs happen to be sociopaths?
1) It shouldn't matter if anyone is a sociopath as long as they do not break any laws.
2) How would you actually go about getting people people to take this so called concrete test? Would someone have to take this test in order to start their own company?
3) If they are deemed a sociopath, then what? That's not illegal.
This is a slippery slope my friend.
