Sociopaths are not uncommon as people think. They think sociopaths are “mad killers” but they’re just people who don’t feel remorse when ie lying and have little to no empathy. I’ve met mild sociopaths who were just bankers who would never even think about second order and third order effects of what they were doing. It’s not some kind of rare condition.

I heard the figure was 1 in 30 but 1 in 20 is close enough.
