I see [activists] getting really angry that people won't just do what the evidence tells them, and that's not very helpful. You need to actually think why that is.

If you were disabled in Russia, you had to re-register every year, and it took up to six months to re-register, so people who lost limbs in Afghanistan had to prove that their leg hadn't grown back.

Often we're having an argument with something imaginary - a fixed idea of the "enemy" and the good. We need to get beyond that and actually develop a deep curiosity about people and systems and understand them better.

People think there's a single solution to complex problems, and the solution is often making an enemy of a group of people - pulling back and rejecting the other.

There's a tendency for people who believe passionately in something to be so convinced of their rightness that if they just repeat themselves a lot at the person, that will convince them. And that hasn't worked on things like immigration or trade deals.

The magic formula is there is no magic formula.

People are saying, "I have a right to my opinion. Don't just keep condescending, telling me what to think." There's something slightly liberating about that, but also it lends itself to being taken advantage of, because in come the demagogues.
