What you don't do is just say, "I've got all the ideas and all the knowledge, and listen to me."

Activists can get very preachy about things. It's more about understanding people's own experiences and tapping into them.

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

The death of deference seems to be general at the moment, so everybody has to earn their reputation and trust all over again. You don't just get it by virtue of being a professor or a politician or anybody else.

When you get talking to people in positions of power, you find that often their worldview is framed either in terms of their disciplinary studies at university and/or the country where they first got interest in development.

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 post-Second World War simple system of social democracy and organized labour has fragmented massively, but just because people aren't organized in workplace trade unions doesn't mean they aren't in associations with other people - work-based, place-based, culture-based, sport-based, faith-based - there's a bit of an old rainbow coalition argument.
