I think that this emphasis on explicit, built-from-scratch mathematical proofs runs counter to your previously expressed suggestion that learning via pattern matching is more efficient than learning via explicit reasoning.
I've found that the emphasis on first principles is often symptomatic of someone who is speaking for their own benefit rather than that of their audience. After all, you're making the unwarranted assumption that A.) your audience wants first principles rather than a practical application, and B.) your audience is, for lack of a better wo...
It's funny you mention that, that feature is actually built into the tool, it's just I hadn't written a user interface for it yet. I got your message as well, let's set up some time to talk.
The roadblock I came up against was how to return results that are useful. Many desirable-at-face-value careers (e.g. Artists, actors, etc.) have pretty high 90th percentile salaries but low average salaries. Is it useful to show people something that's possible albeit unlikely? One implementation I had toyed with was showing the number of people at that position actually making that kind of money.
Ability to compare multiple jobs simultaneously. Make a note saying the graph will appear once you pick a job, or have it pop up by default on a default job. Center the numerical figures in their cells.
One thing I was thinking about on this note was, comparing the "true cost of post-graduate education", in other words, you choose a job that will require X years of post-grad, and then you choose a job that doesn't. And it will compare lifetime earnings.
...Make the list of jobs and/or the list of categories searchable and associate search key
In my experience, at the under-grad level, the college you go to doesn't really matter (and especially your grades). I know that when I am hiring, I personally spend exactly 2 seconds looking at what school someone went to (and exactly 0 seconds looking at their grades).
It may be different at the post-graduate level though.
I think that's because, when looking at the aggregate of society, it's more efficient to bring people up to the level of semi-proficiency than it is to bring them to the level of expertise. If you have 100,000 hours of training to allocate, you get more bang for your buck to train 50 people to 80% proficiency than it is to train 10 people to the level of an expert.
The flaw, of course, is that "training hours" isn't a finite, discrete resource. Any individual can opt to spend additional time of their own accord if they are truly passionate. The p...
The definition of "fundamentals" differs though, depending on how abstract you get. The more layers of abstraction, the more abstract the fundamentals. If my goal is high-level programming, I don't need to know how to write code on bare metal.
That's why I advocate breaking things down until you reach the level of triviality for you personally. Most people will find, "writing a for-loop" to be trivial, without having to go farther down the rabbit hole. At a certain point, breaking things down too far actually makes things less trivial.
Yes, this this this this this this this. "The capacity of human minds is limited and I'll accept climbing up higher in abstraction levels at the price of forgetting how the lower-level gears turn." If I could upvote this multiple times, I would.
This is the crux of this entire approach. Learn the higher level, applied abstractions. And learn the very basic fundamentals. Forget learning how the lower-level gears turn: just learn the fundamental laws of physics. If you ever need to figure out a lower-level gear, you can just derive it from your knowledge of the fundamentals, combined with your big-picture knowledge of how that gear fits into the overall system.
It sounds like both you and estimator are actually both on the same page: estimator seems to be talking about the "prerequisite" in the sense of, "systematic prerequisite", as in, people say that you should learn X before you learn Y. You seem to be talking about "prerequisite" in the sense that, "skill X is a necessary component of skill Y"
Both of you, however, seem to agree that you should ignore the stuff that is irrelevant to what you are actually trying to accomplish.
First and foremost, don't bother with Java, it'll be dead in 5 years. (Okay, just kidding, sorta.)
Okay, so jokes aside: what do you want? As in, what do you hope that the world will accomplish before you die? Even if you aren't the one who makes the breakthrough, you still benefit. So, what do you hope that someone, anyone, it could be you, it could be some scientist somewhere else, what do you hope they will do, more than anything else?
You seem to point to things that revolve around life extension, and your thought that current methods aren't going to g...
There's a big difference between the fundamentals, and the low-level practical applications. I think the latter is what estimator is referring to. You can't really make a breakthrough or do real research without a firm grasp of the fundamentals. But you definitely can make a breakthrough in, say, physics, without knowing the exact tensile strength of wood vs. steel. And yet, that type of "Applied Physics" was a pre-requisite at my school for the more advanced fields of physics that I was actually interested in.
I go into this in further detail in this post
Defining the success conditions is a critical first step, and you'd be surprised at how many people don't do that. Many people frame their goals as a state-of-being, e.g. "I want to be the fastest runner in the world" rather than a success-condition, e.g. "I want to beat the current world record holder."
Okay, so I made a significant revision of the post. The original ideas are all there, just written in a much less obtuse manner.
So, after some cursory thought, naturally the part of the system that gives you the most bang for your buck are the first 4 steps. The last 3 steps are designed to help you improve, which is a much slower process than just learning the basics.
So, now to figure out how to recursively apply the the skill of learning a skill quickly to the skill "learning skills quickly".
As I mentioned in another comment, the difference between this and the "common sense" approach is in what this system does not do.
As for what the 20% of this system that gives you the most bang for your buck? That's a good question. Right now my "safe" answer is that it's dependent on the type of skill you're trying to learn. The trouble is that the common threads among all the skills ("Find the 20% of the skill that yields 80% of the results") doesn't have a lot of practical value. Like telling someone that all they need to do to lose weight is eat less and exercise more.
Let me think about it some more and I'll get back to you.
Well of course they do. Because these things are necessary to learning a language. This is the 20% that's most efficient. By definition someone who puts in 100% of the effort will be doing what I did.
The efficiency of this approach revolves around what you don't do. You're excising the 80%. I didn't spend long hours learning katakana, hiragana and kanji. I didn't learn the more complex tenses and conjugations. I didn't spend time on vocabulary words that are highly situational. Contrast this to a typical Japanese textbook.
I'll give a more in depth breakdown soon but for now, I'd probably take a similar approach that I took to learning to read Japanese : learn basic sentence structure, learn top 150ish vocabulary words, avoid books written in non-romaji. Practice hearing spoken word by listening to speeches and following their transcriptions. My exception protocol for unrecognized words was to look them up. And for irregular sentence structure, to guess based on context. It worked for watching movies and reading, mostly but as you can tell, yoi kakikomu koto ga dekimasen*. I...
Also, when you say "intermediate level language knowledge", what exactly do you mean? One of the key steps is defining exactly what you want to accomplish and why. I don't want to create a whole write-up, only to realize that you and I have two different definitions of "intermediate level language knowledge".
So if you'd tell me the "what" and the "why", I'll do the rest.
Basketball is an example. I'm about to head home so I'll do the ultra-abbreviated TL;DR version:
That's totally fine, like I said, your post made sense and was consistent with what I've seen.
I still don't really think that stating my qualifications would do much. In this context, it still just seems too much like bragging. "I helped build a multi-million dollar company, I compete in barbecue competitions and consistently place in the top 10% of the field and was sponsored by a major barbecue website, was ranked in the top 100 players in the world for a popular collectible card game, learned how to code with no formal education (and used that know...
Yup, pretty much. To quote myself
TL;DR: The fastest way to learn new skills is to 1. Break it down into enough "recipes" or "how-to" guides that they cover most of what you might encounter, and 2. Figure out how to eloquently ask for help if you don't know what to do.
(Incidentally, the link you posted does not work, it's giving me a 404).
Articles on such topics are notorious for their average bad quality.
That's interesting, I wasn't aware of that reputation. That's good to know and certainly justifies your skepticism.
All that said, I think one can still evaluate your point (and in my case, my Less Wrong post) based on its internal logic and how consistent it is with one's own observations, without needing research to back it up. It would be easy enough to dismiss your own post for the very reasons you cited. Consider the following:
"In general, people new to a community are notor...
I agree that in some cases, it's better than nothing to include personal achievements (as I did when I was discussing socializing in another thread). I just don't really think that's the case here. I'll say the same thing that I said to estimator: if you genuinely think that my personal achievements would make a difference to you, I'll be glad to tell you.
As for relevant research, well, (and I might be wrong on this) I thought one of the purposes of LW was to produce original content. Again, I might be misinterpreting things here. But if there was research that said, "Such-and-such approach to skill-learning works well", why not just link to that instead of trying to paraphrase it?
Sure, I could, but would that make you any more likely to accept it? Generally I've found that the more someone expounds on their own credentials, the less credible (and likable) they sound.
If my own personal achievements would genuinely make a difference to you personally, then I'd be glad to tell you them. If not, then I don't quite see the point.
Articles on such topics are notorious for their average bad quality. Reformulating in Bayesian terms, the prior probability of your statements being true is low, so you should provide some proofs or evidence -- or why I (or anyone) should believe you? Have you actually checked if it works? Have you actually checked if it works for somebody else?
I don't think that personal achievements are a bullet-proof argumentation for such an advice. Still, when I read something like this, I'm pretty sure that it contains valuable information, although it is probably a...
Here's an example of this process applied to learning a foreign language:
Define the goal: I want to be able to a. interact and b. converse and c. function in a society that speaks a different language.
Archetypes: Most of the time I spend talking with others in person is spent a. eating/drinking/buying things, b.asking for assistance, c. meeting new people. To break those down into subtypes, I'd say:
I definitely agree that you shouldn't be so brief as to not get your point across, I think the level of brevity depends on what your goal is. In this case, he's asking for help. It isn't until 1,500 words in that the two most important questions: "What does he want?" and "Why should I help him?" are answered.
(Besides, he specifically wanted help in communicating things succinctly.)
Here is the even-further edited version, condensed to 150 words.
...I have a lot of evidence that the most effective people in the world have a very specific way of thinking. They use their brain's pattern-matching abilities to process the world, rather than using explicit reasoning.
Our brain can pattern match much more efficiently than it can reason. Most people can recognize a cat very easily. But creating an algorithm to recognize cats is far more difficult. And breakthroughs of any kind are very rarely made via explicit reasoning, but rather through a
Per our email exchange, here is the condensed version that uses only your original writing:
..."Our brains' pattern recognition capabilities are far stronger than our ability to reason explicitly. Most people can recognize cats across contexts with little mental exertion. By way of contrast, explicitly constructing a formal algorithm that can consistently cats across contexts requires great scientific ability and cognitive exertion.
Very high level epistemic rationality is about retraining one's brain to be able to see patterns in the evidence in the s
While I agree that there's value to being able to state the summary of the viewpoint, I can't help but feel that brevity is the wrong approach to take to this subject in particular. If the point is that effective people reason by examples and seeing patterns rather than by manipulating logical objects and functions, then removing the examples and patterns to just leave logical objects and functions is betraying the point!
Somewhat more generally, yes, there is value in telling people things, but they need to be explained if you want to communicate with people that don't already understand them.

There's a pretty noticeable difference between someone doing something for their own sake and someone doing something for the sake of another. Compare two pretty universal experiences: "Talking to someone who is only interacting with you because they want something" and "Being the recipient of a no-strings-attached favor".
This attitude is universal; it's not specific to business. Everyone has wants and goals, not just business people. What you imagine my life situation to be isn't really very relevant. Unless you live in a solitary confinement, this is applicable to you.
Thanks for the reply. The part about it being "really easy" was a glib attempt at humor, in the same vein as saying, "Losing weight is really easy: you just stop eating so much and start working out more!" Or "It's easy to quit smoking, just don't smoke!" As with many things in life there's a big gap between knowing what one should do and then actually doing it.
As you said, intellectually accepting something tends to be much easier than emotionally integrating it. I wish I had better advice when it came to that part of things...
If you understand the concept that other people have value, then it sounds like your primary issue is just with the semantic meaning behind "genuinely caring about other people's success". Which is fine, it's an overly complex idea to try to distill into a single sentence and I would expect there to be a fair amount of clarification needed.
But to be clear, it's a semantic disagreement rather than one about the underlying meaning. If I had to be less succinct with my explanation I'd say: "Being confident enough in one's own self-improvement ...
Your reluctance is both common and understandable. But it's actually not that difficult to reconcile. Let's talk about this from an egoist perspective. First of all, why should you care about other people? Simple: other people are a potentially valuable resource. Despite protestations otherwise, many smart people labor under the delusion that they are of singular genius and importance, and thus have a very difficult time truly grasping the idea that other people can be as valuable as they themselves are.
Your car, computer, bike, house, appliances, etc. a...
Some quick background: a friend and I run the sales department of a multi-million dollar company. We built that company from the ground up from about 15 clients to 5,000 and counting, and now manage 20+ sales reps.
Contrary to popular opinion, social interaction is really fucking easy. There's one common trait among likable people, (and I don't mean likable in the shitty, salesy sort of way where a person is so outgoing you feel obligated to say you like them, when in fact you think they're a giant turd)). That trait can be easily explained: you truly, ge...
Am I going to receive my own message no matter what and the attacker is only going to try to confuse me with another message or messages?
For the sake of this, you can assume you will receive your own message no matter what. An alternate way of phrasing it would be, "Your memories have been wiped. You wake up and you find a message that purports to be from yourself. What would the message need to contain in order for you to be highly confident the message actually did come from yourself."
I edited the post because I forgot to include a key constraint to the problem, which is that an attacker can/will be trying to send you false information from "yourself" so you need a way to distinguish. In this case it's relevant because an attacker could cover you with tattoos before your memories were wiped.

In this case it's relevant because an attacker could create a false message and force you to swallow the key to that message right before your memories were wiped.
Note that I said "all the potential security flaws we've discussed here". Not, "any possible security flaw."
This is precisely why I've been annoyed by the direction this thread has taken. If someone wants to talk about potential flaws specific to this tool, I'm all ears. But instead it's mostly been a discussion about all the different ways I could possibly slip a Trojan into this tool.
