People try to change the world all the time – as activists or politicians, as advocates or advertisers, or as soldiers and revolutionaries. Sometimes it totally fails, and sometimes it builds up momentum that dissipates, and sometimes a revolution happens – but then it peters out, and things go back to normal. Why is that? And why and when do change attempts catch fire, edge over the tipping point, or finally effect social change?

This talk looks at campaigns as diverse as climate change, health, counter-terrorism, financial literacy, and analyses why and how they fail and succeed.
