"Statisticians think everything is normally distributed" seems to be one of those weirdly enduring myths. I'd love to know how it gets propagated.

I can't say I ran into it before (whereas "economists think humans are all rational self-interested agents", jeez...)

Pretty neat website you got there!

Knocking through a bunch of exercises every day feels efficient but it's not exactly fun and I put in less time than I should.

I've been reviewing Anki pretty much daily for the past couple of years, and I put in enough time to have all my cards reviewed. What helps:

  • Doing it on my smartphones at times were I can't do much else anyway (in public transport, waiting in a queue); the most "productive" thing I could be doing with that time is reading a book, and even then, reading a book standing up is more of a hassle than looking at my smarphone.
  • All the stuff in it is stuff I added myself and considered worth learning, and if I have doubts about something (a card or a whole deck), i'll often suspend or delete it
  • "Finish today's cards" is a reachable, definite, objective (more so than "a bunch of exercises") but I still don't put big pressure on myself, since if I'm too busy to review today, I'll review a bit more tomorrow, and eventually catch up (I don't need to explicitly decide "I'll review some more to compensate", I just will have more due cards tomorrow).
  • I only add new cards if I don't feel overwhelmed by the daily review schedule

(and yes, I've been using this to learn Japanese and to review my Mandarin and German)

Alternative implementation: an android widget that posts a "snitch" message somewhere online if ever your phone is unlocked in certain time frames; such that other people can easily see online whether you unlocked your phone in the "forbidden" timeframe.

In response to Learning by Doing

I think the learn to program by programming adage came from a lack of places teaching the stuff that makes people good programmers. I've never worked with someone who has gone through one of the new programming schools, but I don't think they purport to turn out senior-level programmers, much less 99th percentile programmers. As far as I can tell, folks either learn everything beyond the mechanics and algorithms of programming from your seniors in the workplace or discover it for themself.

So I'd say that there are nodes on the graph that I don't have labels for, and are not taught formally as far as I know. The best way to learn them is to read lots of big well written code bases and try to figure out why everything was done one way and not some other. Second best then maybe is to write a few huge code bases and figure out why things keep falling apart?

... or from Stack Overflow / Wikipedia, no? When encountering a difficult problem, one can either ask someone more knowledgeable, figure it out himself, or look it up on the internet.

Calling things "an art, not a science" has always been a pet peeve of mine. And I've heard people say things like, "there's no best way to do it'. In particular, I'm taking a Responsive CSS course on Udacity and the guy said these things (if you listen closely, you could hear me cringe).

And then there's the idea that art is like inherently intuitive, whereas science isn't. I want to focus on the "art is inherently intuitive and not about breaking things down into components like science" part. My thought is that these people who say this are confusing their map for the territory. They may not know how to deduce what the perfect painting would look like, but that doesn't mean that it's not possible.

I know that there are different versions of these beliefs, and that I may be misunderstanding them. If so, please correct me. Anyway, what do you guys think?

One charitable interpretation is "it's something you learn by doing, not something you learn by reading".

"Art" has a bit of a double meaning, there's the "something that's pretty/pleasing/aesthetic/original/creative", but there's also the "craft" meaning, as in "the art of XXX".

I want to focus on the "art is inherently intuitive and not about breaking things down into components like science" part. My thought is that these people who say this are confusing their map for the territory. They may not know how to deduce what the perfect painting would look like, but that doesn't mean that it's not possible.

Two reactions to this:

1) If someone says something can't be broken into component parts, a more charitable reading is that they think that trying to do so is a waste of time and less likely to bring progress than just a lot of practice. Even if it's possible in theory, that doesn't mean it's actually a good idea, so warning people against it can be totally reasonable, and isn't "confusing their map for the territory".

2) HOWEVER, in the case of art, most forms of art I can think of - drawing, painting, storytelling, animations, etc. - most definitely CAN be broken into component pieces, and often those component pieces can be broken into component pieces too, etc. - just check out the right section in any library.

You can't learn to draw by reading a book, but a good book on drawing can tell you what individual skills you should practice, and how to do so.

[Cross-Posted from the "Welcome to LW" thread] I'm a long-time user of LW. My old account has ~1000 karma. I'm making this account because I would like it to be tied to my real identity.

Here is my blog/personal-workflowy-wiki. I'd like to have 20 karma, so that I can make cross-posts from here to the LW Discussion.

I'm working on a rationality power tool. Specifically, it's an open-source workflowy with revision control and general graph structure. I want to use it as a wiki to map out various topics of interest on LW. If anybody is interested in working on (or using) rationality power tools, please PM me, as I've spent a lot of time thinking about them, and can also introduce you to some other people who are interested in this area.

EDIT: Added the missing links.

But is arrogance justified in an epistemic sense? If you regularly score at, say, the 99.9th percentile on standardized tests or [insert-preferred-method-of-evaluation-here], does that entitle you to be dismissive of someone's arguments (even if you don't give any outward sign of it) until you see sufficient evidence that that person is likewise exceptional? (I'm not being rhetorical here; this is a question that I'm genuinely undecided on.)

Comment author: Emile 23 March 2015 08:47:36AM 1 point [-]

I'd say there are cases where it's reasonable to dismiss others' opinions out of hand (apart from politeness etc.) BUT it takes more than "I'm much smarter than them"; there should be a factor like "I have all the evidence they have / I know all they know on that topic" and of course "I have good reasons to believe I'm smarter than them and know more".

And even then it's the kind of thing that's reasonable "on average", i.e. it can be a decent time-saving heuristic if needed, but it can still get wrong. Say Alice is studying for a Masters degree in physics and Bob, a high-schooler who's not exceptionally bright (Alice had better science grades then him in high school), disagrees with her on something about black holes. As a rule of thumb, Alice is probably right BUT it happens that Bob just spent the summer camping with a family friend, Calvin, who's a physicist and just wouldn't shut up about black holes, explaining a bunch of concepts and controversies to Bob the best he could. Now it's pretty likely that Bob is actually right (though Alice might be justified in not listening anyway, depending on how good Bob is at explaining his position).

Am I the only one who thinks that there's some kernel of truth in this? that many people's perception of 'quality' is very strongly influenced by the perceived social status of the creator?

Comment author: Emile 17 March 2015 08:53:47AM 0 points [-]

I think that for the specific case of Harry Potter Fanfic, this hypothesis has been disproved by [Yudkowsky, 2010].

Though for "many people's perception of 'quality'", there's probably some truth there.

Yeah, I get the whole weirdtopia thing. But like Mark says, its probably not the best weird thing to be chosen.

And if people can't understand that and read any kind of far-off weirdness through the lens of this decade's petty tribal politics, then basically, fuck 'em.

In one way, I think this attitude is commendable - interlectual and artistic integrity and not having to kowtow to people who are offended. But at the same time, 'anyone who disagrees can just fuck off' ... its not the best PR. And I don't think 'not being scared of rape' is an important criteria for rationalists.

I've read a similar idea to legalised rape before, in the context of a future where it was considered extremely bad manners to refuse sex. I can kinda imagine this could work. But legalised violent rape...

What I imagine would happen is that one person would try to rape another, they would fight back, their friends would intervene, a full-blown bar fight would ensue, someone would smash a bottle, and people would end up in the hospital, or the mental asylum, or the morgue.

Or are they not allowed to fight back? Is it maybe just date rape which is legal, or can you for instance, kidnap and rape someone who is on their way to an important business meeting? Do people say "First on the agenda, Mrs Brown and Mr Black give their apologies that they are unable to attend the emergency meeting on disaster relief for Proxima centuri - alpha, as Mrs Brown has contracted space measles and Mr Black is otherwise engaged in being anally gang raped"?

I mean, even if everyone in the future are the sort of ultra-kinky people who enjoy being raped, and everyone is bisexual to avoid the problem of being raped by the wrong gender, it still doesn't make sense.

It might be worth rereading the passage in question:

The Confessor held up a hand. "I mean it, my lord Akon. It is not polite idealism. We ancients can't steer. We remember too much disaster. We're too cautious to dare the bold path forward. Do you know there was a time when nonconsensual sex was illegal?"

Akon wasn't sure whether to smile or grimace. "The Prohibition, right? During the first century pre-Net? I expect everyone was glad to have that law taken off the books. I can't imagine how boring your sex lives must have been up until then - flirting with a woman, teasing her, leading her on, knowing the whole time that you were perfectly safe because she couldn't take matters into her own hands if you went a little too far -"

"You need a history refresher, my Lord Administrator. At some suitably abstract level. What I'm trying to tell you - and this is not public knowledge - is that we nearly tried to overthrow your government."

"What?" said Akon. "The Confessors?"

"No, us. The ones who remembered the ancient world. Back then we still had our hands on a large share of the capital and tremendous influence in the grant committees. When our children legalized rape, we thought that the Future had gone wrong."

Akon's mouth hung open. "You were that prude?"

The Confessor shook his head. "There aren't any words," the Confessor said, "there aren't any words at all, by which I ever could explain to you. No, it wasn't prudery. It was a memory of disaster."

"Um," Akon said. He was trying not to smile. "I'm trying to visualize what sort of disaster could have been caused by too much nonconsensual sex -"

"Give it up, my lord," the Confessor said. He was finally laughing, but there was an undertone of pain to it. "Without, shall we say, personal experience, you can't possibly imagine, and there's no point in trying."

The passage is very clearly about value dissonance, about how very different cultures can fail to understand each other (which is a major theme of the story). They don't go into details because the only reasons characters bring it up is to show how values have changed.

And sticking to a less-controversial example would have defeated the point. And for illustrating this point, I much prefer this approach (meta talk between characters about how much things have canged) than one that would go into details of how the new system worked.

Counterexamples: Bill Gates nor Arnold Schwarzenegger seem respectively 100% geek and 100% jock, and are among the most successful people on earth. Which seem to show you can be extremely successful without "striking a balance".

Going 100% geek seems like a perfectly viable strategy, especially if you mostly care about success at geeky things (which amazingly a lot of geeks do).

Which isn't to say there aren't any "geek failure modes" to avoid, but "try to strike a balance between geek and jock" doesn't seem like a very useful rule of thumb.
