- I see your point. On the other hand, I find your suggested replacement hard to parse, too - I can't imagine someone coming to this for the first time will understand what "is explicitly regarded" means. Need to give it some more thought.Feb 1, 2014
- The Wason Card Test is very interesting, but my point is somewhat different. At least as I've had it explained to me, the point of the Wason Card Test is that our ape brains find it much easier to reason about social contexts that are formally identical to some abstract problem than to reason about the abstract problem itself.
My point about emotion is much broader and less specific. What I think is perhaps most important is the (very obvious) point that the more we care about something, the more effort we're likely to put into it [*]. While this is obvious, many approaches to pedadogy (indeed, to life) ignore it, or act in a way that is opposed. I find this a lot in my own work - regularly revisiting questions like "Do I really care about this?" and "Why care about this?" helps a lot; I find myself going down wrong paths when I don't do so.
([*] With some obvious caveats. People sometimes care so much about something that they tie themselves up in knots about it, and can't work. But I'm speaking in the more typical case.)Feb 1, 2014
- On software figuring out what learning style works best: it sounds like a great idea. But as a practical issue I wonder about how much content needs to be created in this case? There's a huge overhead involved in catering to multiple learning styles. Not that it's not a great idea, in principle, of course!Feb 1, 2014
- +1 for the "bath leaks" comment alone, it gave me a smile!
On the "series of problems" approach, I've believed since undergrad that the right way to understand something deeply is to be able to reinvent it from scratch (preferably in more than one way). It's often not real reinvention, of course - one picks up various hints and facts along the way, and those things help tremendously. Still, it's a useful mental discipline, and sometimes leads to original creative insights.
The writing approach in the Bitcoin post (and several of my other essays) is simply a cleaned-up, narrative form of this reinvention process. It is cleaned up a lot, of course, and uses a fair bit of dramatic license to make things easier to read. Some people enjoy the style; others hate it.Feb 1, 2014
- Here's a really good visualization of Simpson's paradox:

- Maybe you could further improve your visual explanation when you use 2D. I tried it with a simple image here:
