I'm not sure these are _black_ pills, but I think they are _facts_, and they're pretty dark. But you have to acknowledge them before you can start making a good model of people's behavior.
First: people are very tribal. Even in America, where most people don't know their ancestry, or it's very mixed, people line up with their political allies in a tribelike fashion.
And this means that most of their positions are based on their tribal affiliation.
Second: everyone wants to look good, and it's easier to talk the talk than to walk the walk.
So you get meme sharing, slogans, and slacktivism rather than real policy proposals. You get guaranteed to fail bills in The House to make Reps look like they're fighting.
