It would be better to use geolocation to see if the user is near a meetup and if so, we could show that in a little notification window at the top

on: Rethinking Education
I work for an educational maths company and we are working on implementing a fine-grained Knowledge Graph as are a number of our competitors.

I can’t see a government successfully implementing all of this by itself. Fortunately, intelligent online tutoring software has really taken off because of Khan Academy. Charter schools will be the first to structure their lessons to take advantage of the flexibility this software provides in terms of having students working at their own rates. Eventually, I imagine that educational departments will notice that this works and restructure themselves around this model too, but this will be a slow process.

It is one of the most important things and extremely cost effective

Given enough data, the dependency tree can be inferred implicity from and we can also learn to accurately identify when a student doesn’t understand a concept. I’m actually working on this exact problem right now

It is possible to detect correlations between questions (or even individual steps) and to implicitly determine skills at an even more fine grained level than that—given sufficient data. We aren’t aiming to get that specific right at the moment—indeed, we mightn’t have collected enough data yet to do that—but there’s no reason why we shouldn’t be able to do that

Having tagged data is extremely useful for designing these kinds of algorithms, but we would only require a proportion of the data to be tagged. So it wouldn’t be anywhere near as costly as you expect

Quora has a not very prominent, but extremely useful “best questions section”. This, along with the Quora newletters provide me with a large amount of high quality content

on: Conceptual Analysis and Moral Theory
I think that some basic conceptual analysis can be important for clarifying discussion given that many of these words are used and will continue to be used. For example, it is useful to know that “justified true belief” is a useful first approximation of what is meant by knowledge, but that the situation is actually slightly more complicated by that.

On the other hand, I don’t expect that this will work for all concepts. Some concepts are extremely slippery and will lack enough of a shared meaning that we can provide a single definition. In these cases, we can simply point out the key features that these cases tend to have in common.

Scope insensitivity, utilitarianism vs. deontology, ect. are all good things to know, but they wouldn’t place in a list of the biggest mistakes smart people make

“Of the 9 articles or ideas that you want to see on LW, you listed 2 posts, Mestroyer and others listed 4 more, plus a few posts germane to the idea of smart people fail modes”—There are quite a few posts, but they are scattered over the whole site, rather than collected in a sequence or in a page.

Interesting feedback.

When I said that it is learnt observationally, I mean that if someone simply tells you something, eg. that you should use social touching (http://www.businessinsider.com/habits-of-incredibly-charming-people-2014-4?IR=T), it doesn’t give you enough information to be able to integrate it into your habits. You’d want to actually see other people using that technique, then you might be confident enough to try it yourself without worrying that you were doing something inappropriate. Now you could try and write a description of what situations it works and what situations it doesn’t—but that would be very hard to enumerate and the instructions would be very hard to follow. But if you just show someone a few situations, they’ll probably be able to figure it out.

So, I was talking about observation vs. description—I wasn’t talking about the trade-off between time spent observing and time spent practising.

In the longer term I might—I didn’t actually expect anything to come of this post. But there’s just so many ideas of projects that I have that it is worthwhile to put ideas out there and see what criticisms people have and the general level of interest before I decide what to work on.

Yeah, I did do a bit of review (reading back through my notes), but I kind of fell out of that habit because I became too busy. I never got round to trying to implement a spaced repetition system because higher priorities took over.

I’d love to see a place for aspiring rationalists to discuss politics, but not on the main site. It’s a shame that the subreddits feature was never turned on for discussion

in reply to: Richard_Kennaway’s comment on: Raven paradox settled to my satisfaction
“A further elaboration then occurred to me. If non-ravens are, as the above argument claims, not evidential for the properties of ravens, then neither are non-European ravens evidential for the properties of European ravens, which does not seem plausible.”—Wait so you’re saying that the argument you just made in the post above is incorrect? Or that the argument in main is incorrect?

on: Truth and the Liar Paradox
I just wanted to make one thing absolutely clear—when I talk about “truth as a construct” I don’t mean it in the pseduo-philosophical manner (“but you aren’t objective”) that it is used in post-modern philosophy.

Thanks to those who explained why they disagreed with this article!
