Tell me something I don't know

I posted recently about two episodes of Freakonomics Radio that I found particularly insightful. Now one of the hosts of the show, Stephen Dubner, has created a game show, Tell Me Something I don't know.

There is a wonderful new trend in entertainment (which, like most trends is really just a revival of an old trend) which celebrates curiosity and what Richard Feynman called The Pleasure of Finding Things Out. This game show challenges contestants to tell a panel of learned judges something they didn't know before. 

The latest episode, titled It's Alive, includes facts about killer snails, zombie jellyfish and poop. You can listen at tmsidk.com and be entertained with your education.

This follows on the tradition of a UK show called QI (which stands for Quite Interesting) which was a game show with a similarly strange educational bent. Actually, if you listen through to the credits at the end, you'll hear that their "transatlantic consultant" is one of the "QI Elves" and co-hosts of the podcast No Such Thing as a Fish

In praise of Incrementalism

Two of my favourite authors are Steven Levitt and Stephen Dubner, the duo behind the Freakonomics series of books and the eponymous podcast which has now been running for over five years. They have a wonderfully insightful approach to tackling problems using information and data.

"The Hidden Side of Everything"

Many of the most interesting, and arguable the most important, questions for society are also the ones where it is hardest to collect and evaluate hard empirical data. What often tends to happen — informally at least — is that questions that should be empirical questions (like "What is the air speed of an unladen swallow?") get delegated to other fields like philosophy — or worse, religion. (Remember that up until a few hundred years ago, there was no distinction between science and philosophy.)  It's important to recognize the difference between questions which are not scientific, and questions which are scientific but have practical challenges associated with gathering the data. You can't put a teacher through the Large Hadron Collider and measure its properties, but there are empirical ways of evaluating good and bad teaching techniques. 

Recently, the podcast featured to two particularly insightful episodes, back to back: In Praise of Maintenance and In Praise of Incrementalism. They argue that when it comes to things that improve the human condition, we often put our focus in the wrong place, putting emphasis on so-called "revolutionary" advances. They point out first that it's the more "boring" activities like keeping the roads intact and making trains run on time that account for most of the wealth (figuratively and literally) in society.

You can listen to the full episode here:

They go on to show (in In Praise of Incrementalism) that most of what we think of as spontaneous revolutionary advances are actually processes that are much more gradual that we often don't take the time to remember properly. You can listen to that one here:
