It really comes down to this: If you have anything, a group, a project, a country, and people are not well-intentioned, things won't work.

This is a study into what leads people to not be well-intentioned. Does it has to be something with their ethics? Are people born to be non-cooperative? From this, you try to devise ways to sort people into well-intentioned or not. This may require a continuous evaluation.

This is not different from what I see in projects like Wikipedia or StackExchange. You are punished, somehow, by failing to be well-intentioned. They have not been entirely successfull in making those communities atoxic, how does those two things relate to each other? 

We try our best, after all, to surround ourselves with well-intentioned people in life.

Well, that is the idea.
