Here’s a 5 minute film I did on Newsnight last week, about how politics needs better data. Specifically, it’s about how politicians misuse statistics, how we can stop them, and how we can generate better evidence on what works, and what fails.
If you’re interested in more on this topic, well… there are some good examples of dodgy government stats on this site, and in the chapter on Dodgy Government Statistics in my latest book. For more about randomised trials of government policy, here’s a Radio 4 documentary I did on them, here’s a Cabinet Office paper I co-authored on them, and they crop up in this that I did for the Department of Education. If that’s not enough then I’ll write some more.
