For all its flaws, I mostly enjoyed the book, 'Freakonomics', a couple of years ago.
This podcast is hosted by co-author Stephen Dubner and treats just as various and not per definition economic topics, in very much the same energetic, not to say slightly hysterical, way.
Episodes range from 30 to 50 minutes and delve into subjects which seem very American, such as how to become successful in a particular field, how to achieve grit, how to motivate kids to study and what is the problem with American teachers (or; whether the problem is the American teachers).
In all, it's interesting enough, yet at the same time it feels both superficial and strangely biased. (That may depend on the amount of statistics involved, and on my general distrust of statistics...)
