You have a huge number of people who spend their time writing papers which show that migrants pay more to the country than they take out in benefits, and they say, "Why don't you approve of migration? Why don't you open up borders?" They're not able to empathize with how people feel about migration.

In the end, that's a blind alley - we have to get back to being able to think on our feet and react.

There's a diversion between economic reality - integration, global village, everybody depending on everybody else - and cultural reality, which is people feeling invaded, undermined, threatened, wanting to have "stand-your-ground" legislation all over the place. It's alarming because at the moment, the fear is outweighing the benefits, and that's partially because the benefits have been so unequally distributed that lots of people don't feel better off. They feel threatened, angry and despairing.

Some kinds of activists are more willing to try stuff out, see if works and think on their feet, but some of the people who are working on [change] find that very difficult: They've been schooled into thinking you have to come up with the perfect plan in advance. It has become a bit technocratic.

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.

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.

I keep coming back to the phrase "Dance with the system" - not just march onwards no matter what happens.
