More or Less is a radio programme1 and podcast produced by the BBC World Service. The weekly show tries to make sense of the statistics presented in popular media (including the broadcasts of their own organisation1) in a way the average educated listener can understand.
As you might expect, a common thread in the podcast is whether the numbers reported in stories about studies, polls, and surveys are accurate and used appropriately. Spoiler alert: they often are not.
In a recent “bonus” podcast, the host offers a short debunking guide that would fit on a post card2 from his holiday at the shore. “How to question dubious statistics in just a few short steps.”
The whole thing is worth ten minutes of your time. If you teach math to high school students, you may even want to play it for them.
However, if you’re very short of time, the final step is, for me, the most important idea presented.
Number 6: Be Curious.
If a statistic is worth sharing, isn’t it worth understanding first?
Forget that nagging feeling that says you might just be spoiling a good story. Facts matter… but facts are also fascinating.
Treat them as puzzles. Treat surprising or counterintuitive claims, not with suspicion nor open arms but as mysteries to be solved. It’s fun.
And they close with this reminder.
Hopefully, with this postcard as your guide, you can step into a world of statistical adventure. Because it’s not just about winning arguments, it’s about being curious. The world, after all, is a fascinating place.
Whether you consider statistics “fun” or an “adventure”, the advice is solid. Be curious, some would say skeptical, about the numbers constantly being thrown at you in the news and your social media feed. Very often the story behind them is far more interesting, and different, from what has been presented in the headline.
If you listen to podcasts, More or Less is a good one to add to your playlist. I would have embedded a player here for the episode but the BBC doesn’t allow those of us outside the UK to do that kind of thing.
1. British show, British spelling. :)
2. For you kids out there, postcards were something your parents (maybe grandparents) sent from locations where they were on vacation in the days before Facebook, Instagram, Twitter, and the rest. It was a slower method of trying to impress their friends and relatives. Or maybe make them jealous.
