Having A Good Working Memory

How important is it?

It’s never been one of my strengths. I always liked math and physics because they didn’t require much memorization — I could just rederive formulas on the fly. One of the reasons that I never seriously considered being a doctor was the amount of memorization required. And I think that for that profession in particular, memory is important, and apparently more so than intelligence or processing capability, because I’ve met doctors who I didn’t think were all that smart, and I don’t intrinsically respect them just because they’re doctors. At least not as much as they and society thinks I’m supposed to.

Non-Intuitive

A few years ago, on a Delta flight, I noticed that the airline was boarding people in the middle first. I asked the flight attendant about it, and he said that studies had shown that it was faster than back to front, which surprised me, because the latter had always been conventional wisdom and industry practice. Now, American claims that, based on simulations, random boarding is better yet. I’d be interested to see a plausible explanation for this, if true.
