Hi! This is an excellent answer, thanks.

[...] I believe your questions relate to all three ways to different extents (although the title of the post leans towards the HOW types of questions), but I found it useful to differentiate between these issues in order to make sure my time, money and efforts are well spent.

Needless to say that I updated significantly in the past month since I posted this question and the "Why" and "What" has definitely enlarged. I agree with you that it's a useful framework to have. I am also thankful for the practical bits. 

I would like to close my comment by emphasizing that children are born rational beings, but they just start taking over from their parents when they provide them with irrational explanations for things that happen or might happen to them (one of my favorites, here in Romania, is that "If you don't stop crying, a big bad wolf will come and get you"), or they build defenses of their own that are irrational, to protect themselves from being hurt. I believe that our job as parents is, therefore, to be rational and predictive in relation to them, as well as gently making them aware of the instances when they use irrationality to run away from their feelings.

I probably understand what you mean here and agree at least with my steelman version of your argument. But I would also like to emphasize that I want the "other" people which are important for me to understand "rationality" that I can't imagine how one could "born" with. Examples are all the great knowledge of giants on which shoulders we stand on (like, say, probability), "simply" results of scientific progress (like how minds work, or some biases...), or practical guide of "you are a human, try to work with that fact in the best way you can". At least I and virtually everyone I met didn't born with these, nor they figure all that out by themselves.

It's great to see some support like this. Not just to help with motivation but also to see what the interest is. 

I think there is a massive opportunity in creating a k-12 home schooling version of Lambda School but targeted at general knowledge. Why not start by work together on it?

I am interested as it's probably clear from my question, but I don't think I would be a good fit to actually put it together (or that it would be cost-effective). I would be happy to put and run some structure which could do this. I should emphasize though that I am not trying to create a generic program for everyone as I think that's vastly harder and would IMHO need much more.

Hi. Thanks a lot for a really nice write-up. 

It seems that the regulations in the Czech Republic are actually legally "workable", i.e. it's possible to teach kids close to self-directed without having to do a lot of "compulsory curriculum" (i.e. my estimate is <5%). It also seems there is a "subculture" of families doing this and I managed to get to some people who know how to deal with this.

My conclusion is that there is no simple answer.

I don't aim for a simple answer and I do not expect there is some. But as I said, the current system seems so broken that just answering "try not to harm" is a good substitution question. Also, it doesn't really seem that kids would learn [and retain] that much [useful knowledge] compared to "watching youtube videos".

I have concluded that school reproduces more than knowledge. It reproduces culture.

It does so indeed, but that culture doesn't seem to be very worthwhile to me. I am rather tempted to risk this one, as the main thing it signals doesn't seem to be that problematic to pick up later. I.e. homeschooled kids doesn't seem to have issues when they want to switch to formal education, and at "worst" they pay a year or two of whatever-made-them-happy-or-stronger-in-other-ways for that (again, e.g. watching videos :-) ). I have read/heard this claim quite a lot, and I am less and less convinced that this aspect of schooling is positive.

I also think that some other benefits can be supplied in other ways and even more effectively. For example a good social network - it's vastly superior/efficient to learn a few networking skills and just infiltrate e.g. some organizations, events or groups with a "good network". It's unlikely that it's your random class that is "good social network", and e.g. I have literally 0 friends from my primary and secondary school (I have a lot from university though - but anyone can do the uni I did if they want).

The other aspect is that you and I might have good ideas about which curriculum would be best

That kind of links to my previous answer. I am coming to a conclusion that the skills I would like to convey are rather very generic, blurry and meta. I want to teach her how to understand herself, her motivation, discipline, emotions, reasoning, goals and drive, how to understand other minds and how to model the world. I want her to understand how she can learn by herself whatever she wants to learn. It really seems to me that if we don't want to learn something, then we should rather not learn it as we are not going to remember that anyway. And given the right tools and meta knowledge, we can learn almost everything in much shorter times than the "most common" path. Therefore, I don't really care that much about the "object-level" curriculum. I think (but that's still subject to a research) that the concepts important to me can be taught via mostly arbitrary picks in the real world (like nature or engineering) or just going outside and explicitly talk about that person kicking that soda machine. And I can't imagine how these skills would not be useful or universal to time, at least on ~15 years from now scale, as they seem to be useful since eternity. I can imagine my job going obsolete - but I would use exactly these skills to find and learn something else which would be the best in that time for me.

Thanks for the tip and links. Unfortunately, it doesn't show much in Prague (but still gives me a hint about what to look for even if some school isn't registered in the linked project).

The OP seems intent on designing/engineering the perfect education, when the answer from this perspective will require a lot of letting go.

Hm... I don't think I would have issues of having to do so. I am trying to understand how to think about this, and this simply didn't occur to me before. In fact, it seems that me and my girlfriend are currently rather at the side of trying to figure out how to do this in self-directed-way, but it's still in early stages.

Thanks Vil. I agree with Ericf comment that you seem to try to take it more generically than I intended (i.e. I realize that I have resources 99% of the local population doesn't). That said, I fully agree with you on these points.

it takes about 1 hour to teach at home what they teach at school in 1 day

These are good datapoints, thanks. 

And yeah, I would hope that with internet and some good courses which would give the kids some "library" of what I could learn + mixed with the self-driven learning wouldn't need a full attention of a tutor.

Thanks for clarifying my questions.

The key point (I'm synthesizing this from How Children Learn and How Children Fail, by John Holt) [...]

It's very much similar to what @Raj mentioned above, am I right? Seems that Holt advocates for self-driven learning, e.g. from a goodreads review:

Holt believes that children learn best when they learn at their own pace and pursue their own interests--learning should never be forced or uniform, but spontaneous and dynamic. Children don't need to be "taught" -- they simply need to be given opportunites to LEARN

Thanks for the tips though, those two books (How Children Learn | Fail) are definitely going on my reading list.

Hey Raj. Thanks a lot for an insightful post, it's definitely that sort of things I was looking after, regardless if I immediately agree with them or not.

1-self learning: How I read it so far is that instead of selecting "the way" first and optimizing it later, instead it might be a good idea to focus on learning how to learn by yourself first, recognizing what's the most effective in any given case, be it via internet or an actual human resource such as a tutor.

By the way, my solely main motivation for her to know English was the access to much better materials so she can learn by herself.

I would also check out Sudbury or democratic schools, which are schools with high behavioral space and very low in coercion.

A quick search shows that there are some very reasonably priced democratic schools around. So great to see there are some options like this (at least, I will be able to get some references or even visit them myself)

there are a lot of priors I'm guessing we don't share that might make some of this not make sense. Please bring them up and I will try to answer them though most answers could probably be found in some way on

I think your post does make sense to me on this level. I think I have to first go through the linked material, which will surely take some time to process (thanks!).

Thanks @ericf!

How neurotypical is your child?

She's regular kid, so neurotypical. Goes to an English speaking kindergarten (so she speaks fluently two languages + we are starting with Spanish) where she does above average according to the teachers with behavior and socializing, although she prefer playing with teachers and older kids. Thanks to the fact that one of us didn't have to work, we could spend a lot of time with her in the first 3 years and now she can read simple words and sentences (in English - how I hate its irregularities damn!) and do simple arithmetic already. That likely puts her in higher percentiles, but nothing super exceptional nor she shows signs of extremely high intelligence or capabilities. Frankly, she also doesn't have anyone to inherit these from...

Do you have someone who can spend 10-40 hours a week educating them (depending on the first answer), or the cash to hire someone for that amount of time?

Fortunately for me, salaries for teachers are one of the lowest from the OECD. Depending on the efficiency, me paying a private tutor ~30h/week would be technically feasible and I would still have some money left, but it would be at the edge of what I could spend. I believe this cost could be shared through multiple kids if that was the way to go. I myself have masters in CompSci and my girlfriend masters in pedagogy (not the child development though, although I mean it means little here anyway), so homeschooling done by us is also an option but for me there is definitely much higher opportunity cost (and I wouldn't enjoy it full time, same as my girlfriend).

1-on-1 instruction for the (child-dependent) sufficient amount of time each week can be applied by anyone with 1SD above average intelligence and a little bit of "how to teach" education. This is the simplest way to ensure someone learns all the key skills (Arithmatic, Algebra, Reading to learn, Writing to communicate, basic facts about history & science)

Do you have any resources or even anecdotal evidence for this? It sounds true to me, but I would say it's super obvious. Are you referring to e.g. Blooms 2SD?

Once they are old enough to attend High School classes, if you have access to a large (400+ per grade level) school they can get some good specialized classes that would be harder to do with general tutors. Junior college classes are also an option, depending on maturity level.

Sorry, I am not entirely familiar with these as we are not US-based. Based on googling, is what you mean:

  1. large schools having specialized classes: is it that once they are big enough, they can have some special programs like in-depth dive into, say, physics or something? Or do you have some specific classes in mind? 
  2. Junior colleges - we don't really have that where I live, we only have universities, but I think it still applies - she could attend them as they are free to attend for anyone actually (at least lectures).

To be fair though, I am very skeptical I could find many good classes in these, but it's surely an area I want to explore (although it's not a priority now, given her age).

I was searching more about my interests and I've found a opportunity has a nice Bachelor's topic in maths/informatics/neuroscience. I was offered two topics:

  • Analyse properties of correlation matrix graphs (e.g small-world property)
  • Conditional mutual information - how to detect synergy and which values it can takes when there is restriction on cardinality of given variables.

Both are connected with neuroscience (e.g the correlation matrix is created by brain activity, variables are activities of different parts of brain etc.)

Does anyone have any informations or advices to this?

I don't know how I could miss MIRI's course recommendation list. It looks great. Will definitely take a closer look at it.

Second part is a bit disappointment for me, since I'm not that kind of student. I'm in the stronger group of mathematicians in my university, but in that group I'm in or below average (they are one of the best in my country).

Maybe I put too much weight too maths part of AGI, which are obviously aren't for me. And I'm not sure about taking PhD in it right now also. Do I understand correctly that right now there are no less complicated problems or problems for regular people in AGI? Nothing, where I could develop my skills which could be useful even for other ways than taking a PhD and do heavy research with AGI world leaders?

I'd like to get some opinions about my future goals.

I'm 21 and I'm a second-year student of engineering in Prague, Czech Republic, focusing mainly on math and then physics.

My background is not stunning - I was born in 93, visiting sporting primary school and then general high school. Until I was in second year of high school, I behaved as an idiot with below-average results in almost everything, paradoxically except extraordinary "general study presupposes" (whatever it means). My not so bad IQ - according to IQ test I took when I was 15 - is about 130 points. When I was 17, I realized that there is something about the world that needs to be done with. I started to study, mainly math and physics. I was horrible at it - I had very big disadvantage because I missed basics and wasn't able to recognize it. Anyway, I tried (but, unfortunately, not as much as I had to) and reached so-so level and I got on the technical university. Here I tried really hard and I achieved relatively good results and got into the best maths-focused student group. I'm below-average in this group (about 30 students) and my results are satisfactory. I'm quite popular thanks to collaborating on some non-study events for my schoolmates. I also created a presentation for high school students about engineering and I distributed it among faculty workers and students, who are connected to propagation.

About 10 years I obtained ECDL and it started my curiosity about informatics. But nothing special - I was autodidact in HTML and "computer administration" for regular usage. I was also very interested in economy, as my father is working in this area. I actively did cross-country skiing and play on piano and trombone.

I have high charisma, authority and ability to organize people and some bigger events, which I was usually asked to prepare (the graduate prom, matriculation etc.). I have good reasoning skills and ability to negotiate even under heavy pressure and stress. People usually enjoy time with me and appreciates me for my honesty, empathy and "cold-think" reasoning solutions, which in most time shows there were the best possible. I'm in healthy relationship for two years. My family is good background for my activities and support me. They also support me financially. My expense per month is not more than 300 USD including accommodation with in an apartment (university students, two of them from my university and domain), food and social activities.

Currently, apart from my school activities, I'm also attending some kind of philosophy group every week, where we usually discuss some topic about epistemology, relationships, culture, religions etc., we read some philosophic works (Platon), deal with art (classical music or paintings) or we write some kind of voluntary essays. I'm really interested in discussions about these topics and I try to develop my reasoning skills as often I can. For example, now I contacted a priest from local temple with whom I want to discuss some religion based questions. I autodidact psychology (last book I've read was Kahneman: Think fast and slow), rationality (started to read LW sequences), and programming. I enjoy using open source software on my Archlinux laptop and now I dived into Python as a scripting language. I also develop some web for my mother using Django and I also signed for a statistical research task about datamining in Python (pandas, numpy, scikit-learn...) or R. In school I have courses of C++ also. I'm not the most talented or generally best mathematician or programmer, but I have quite good learning (and also teaching) skills.

I've chosen my "path" - I'd like to do what's right and true and seek for the truth whenever it is possible. I feel that I'm not getting everything (e.g. from my school) I need for changing the world to a better place. I could do more. I can't decide where to focus and how to divide my attention and possibilities. Should I do aggressive autodidact of sequences? Should I focus on maths and algorithms or biases? Should I try to develop my social skills?

And the second question is simple:" Are there any Czechs who are interested in meetups in PRAGUE?"

Thank you
