It's more malcolm being malcolm. Not science- just Gladwell ranting, which is fun. Some of his ideas you'll have thought of, some probably not.
I was glad to see a reminder of the if-you're-#20-you'll-try-a-LOT-harder dynamic. There are some fun examples.
If you like this kind of thing you won't really care of what excuse he comes up with to rant more. Or look for him to prove a contention, because he never did, does, or will do.
