It is extremely important to find out how to have a successful community without sociopaths.
(In far mode, most people would probably agree with this. But when the first sociopath comes, most people would be like "oh, we can't send this person away just because of X; they also have so many good traits" or "I don't agree with everything they do, but right now we are in a confict with the enemy tribe, and this person can help us win; they may be an asshole, but they are our asshole". I believe that avoiding these - any maybe many other - failure modes is critical if we ever want to have a Friendly society.)
I think it's extremely likely that any system for identifying and exiling psychopaths can be co-opted for evil, by psychopaths. I think rules and norms that act against specific behaviors are a lot more robust, and also are less likely to fail or be co-opted by psychopaths, unless the community is extremely small. This is why in cities we rely on laws against murder, rather than laws against psychopathy. Even psychopaths (usually) respond to incentives.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
