I would be in favour of an offtopic tab separate from Main and Discussion

Comment author: Lu93 13 August 2015 12:27:55PM 0 points [-]

And then why not do the whole job, and create tab for meetups, to avoid spam in main, tab for AI, tab for decision making, tab for overcoming biases, tab for... Well, we came to my solution. =)

I'd also like to see targeted interaction and outreach to the academic research community.

GiveWell has a good model of validating and checking intuitions against prominent people in development, but seems to opt for public intellectuals over less famous experts in the field who's thinking those public intellectuals may defer to. In the EA community, I feel this has lead to such confidence in deworming, when deworming is actually one of if not the most controversial topics in academic impact evaluation (nicknamed worm wars. And DALY's are the pariah outside of specific subcommunities of impact analysis looking to the future, not immediate use.

There may be many similar misunderstandings in the rationality community which are taken for granted. But unlike the EA community, the rationalist community seems to be less transparent. MIRI technical research agenda is still secret, amongst other things..

By contrasts, I can go on GiveWell, which in some ways isn't part of the EA community so much as the inspiration for it, and see how they think they think and motivating influences cleanly laid out, without even going into their methodology. Be warmed, ordinary readers, I'm playing the critic here. MIRI is much more technically complicated that GiveWell, I'm just trying to give criticism to be constructive. Path dependence and novelty of MIRI's agenda, amongst other things, are obvious barriers to doing things the EA way in the rationalist community.

Btw, I think you've misspelled 'community'. Some members of the community seem really neurotic about that sort of thing and it would be shame if you were downvoted or missed upvotes for something as trivial as that.

Thanks for the warning. I forgot to check the title. Grammar-Nazis always lurk for that fresh non-native-speaker flesh.

I made a post recently that Less Wrong Lacks Direction that seems very similar to point 3. Less Wrong has moderation, but it doesn't have leadership. There is almost no concerted group action. Everyone has their own ideas of what Less Wrong needs to do next, and they are all different.

I think Why our kind can't co-operate is an excellent article. Whenever you post an idea, you might get a few upvotes, but you'll also get a lot of comments saying that something else is a better idea instead.

The reason why Less Wrong is getting less readers is because Less Wrong has much less content. Either 1) we need someone crazy like Scott Alexander who will solo producing huge amounts of content 2) we need some way to encourage the posting of new content. The ability to create separate sections of Less Wrong would be a great way to increase the amount of content posted. The programming wouldn't even be that hard, the issue is that the moderators still haven't commented on whether they'd turn it on if someone went out and did it.

I agree with you completely. Just want to point out that LW lacks directions. It's complete bullshit that we should all focus on one thing. And having all directions interfere is just making it harder to do anything sensible.

Why do you believe that separate sections will increase the amount of content that's posted?

Comment author: Lu93 13 August 2015 11:59:35AM 1 point [-]

He just gave you a reason.

Whenever you post an idea, you might get a few upvotes, but you'll also get a lot of comments saying that something else is a better idea instead.

If you organize content, you would get rid of that sort of things. Imagine going on reddit, to math subreddit, and commenting on some theorem "yeah, but it's better to develop new political system than solving these equations". It's just bizarre, and for a reason: not everyone on this world should be solving the same problem.

Before wanting to grow "the community" it makes sense to ask what "the community" happens to be. You can count Scott's blog into the community or you can decide that the community is only what's branded as LW.

This community is some kind of organization, and it has a goal. To be precise, it probably has two goals, as I see it: to make existing members more rational to get more members.

I wouldn't consider that to be the main goals.

For me one of the most important goals is developing the "art of rationality". A lot of discussion on LW is not about simply applying existing techniques of how to be rational but to develop new concepts. A while ago someone complained that he read a LW post about how to estimate whether a woman will say yes when asked out for a date as probability.

If you think the goal is effective action, there are a lot of reasons why that's not a good way to approach the subject of asking out a woman. If you on the other hand care about how probability estimates are made in emotionally charged real life situations the inquiry is a lot more interesting.

When it comes to gathering new members quality is more important than quantity. At our Berlin LW meetup we could trivially increase the attendance by putting it on meetup.com. We don't and as a result have a meetup with the kind of people who find the event without having to check meetup.

I would STRONGLY encourage new topics

So, what's stopping you from posting new topics yourself?

Comment author: Lu93 13 August 2015 11:52:45AM 1 point [-]

When it comes to gathering new members quality is more important than quantity.

Exactly the reason why I posted. Nobody wants to make a big community by destroying the quality. That's the main topic of this course I recommended.

For me one of the most important goals is developing the "art of rationality". Would it be easier if there were 10 times more people like you, who want to do the same? Would it be easier if existing people were more rational? Your goal has nothing(or very little) to do with my goals, which is self- and world-improvement. So I would call your and my goals as subgoals with regard to community. If any of our goals would be main goal to the community, the other guy would not have interest to contribute. This is the reason i ask for separation of topics.

So, what's stopping you from posting new topics yourself? I just did, my friend. This topic is on growth of the community. What you want to say is "it's not the topic I'm interested in", and that's the reason I want separation of topics. So that I can speak about growth of the community without bothering you.

Ideas on growth of the community

3 Lu93 12 August 2015 06:45PM

TLDR: I had idea to apply some tools I learned on coursera to our community in order to grow it better. I wanted to start some organized thinking about goals our community has, and offer some materials for people who are eager to work on it, but are maybe lost or need ideas.

 

Yesterday I did a course on coursera.org. It's called "Grow to Greatness: Smart Growth for Private Businesses, Part I". (I play lectures often at x2.5 so I can do 5 weeks course in one day)

Though this course seems obvious, it'd say pretty worth 3 hours, so look it up. (It's hard to say how much is hindsight and how much is actually too easy and basic) I got some ideas sorted, and I saw the tools. I'm not an expert now, obviously, but at least i can see when things are done in unprofessional manner, and it can help you understand what follows.

When growing anything (company, community, ...) you have different options. You should not opt for everything, because you will be spread thin. You should grow with measure, so that people can follow, and so that you can do it right. This is the essence of the course. Rest is focused on ways of growing.

This was informative part of this article. Rest is some thoughts that just came to my mind that I would like to share. Hopefully I inspire some of you, and start some organized thinking about this community.

 

This community is some kind of organization, and it has a goal. To be precise, it probably has two goals, as I see it:

  1. to make existing members more rational
  2. to get more members.

Note that second focus is to grow.

I will just plainly write down some claims this course made:

 

In order to grow:

  1. your people need to grow (as persons, to get more skills, to learn).
  2. you need to create more processes regarding customers, in order to preserve good service
  3. you often need better organization (to regulate processes inside the company)
  4. you need to focus
  5. you need a plan
  6. if you need to stop the fire, stop the fire which has the greatest impact, and make a process out of it, so that people can do it on their own afterwards

1. I guess no-one is against this. After all, we are all here to grow.

2. My guess is that our customers could be defined as new members. So, first steps someone makes here are responsibility of this organization. After, when they get into rationality more, when they start working on themselves, they become employees. That's at least how it works in my head. Book on sequences is a good step here since it helps to have it all organized in one pdf.

3. this is actually where it all started. We are just a bunch of people with common drive to be more rational. There are meetups, but that's it. I guess some people see EY as some kind of leader, but even if he were one, that's not an organization. My first idea is to create some kind of separation of topics, reddit-like. (With or without moderators, we can change that at any point if one option does not work.)

For example, I'm fed with AI topics. When i see AI, I literally stop reading. I don't even think it's rational to force that idea so much. I understand the core of this community is in that business, but:

  1. One of the first lessons in finance is "don't put all the eggs in one basket". If there is something more important than AI we are fucked if no-one sees it. I guess "non-rational" people will see it (since they were not active on this forum, therefore not focused on AI) but then people of this forum lose attribute "rational" since "non-rationals" outperformed them simply by doing random stuff.
  2. It may stop people from visiting the forum. They may disagree, they may feel "it's not right", but be unable to formulate it in "dont put all the eggs in one basket" (my example, kind of). The remaining choice is to stop visiting the site.

So, I would STRONGLY encourage new topics, and I would like to see some kind of classification. If I want to find out about AI, I want to know where to look, and if I don't want to read about it, I want to know how to avoid it. If I want to read about self-improvement, I want to know where to find it. Who knows, after some rough classification people start to do finer ones, and discuss how to increase memory without being spammed with procrastination. I think this could help the first goal (to make existing members more rational) since it would give them some overview.

I also think this would reduce cult-ism, since it would add diversity, and loose the "meta".

4. Understatement. Anyone who worked, or read anything about work knows how important plan is. It is OBLIGATORY. Essential. (See course https://www.coursera.org/learn/work-smarter-not-harder/outline )

5. I think this is not very important to us. There are lots of people here. Many enthusiasts. However, this should be some kind of guideline to make a good plan, and to tell us how much resources to devote to each problem.

 

In conclusion, I understand these things are big. But growth means change. (There is some EY quote on this, I think:not every change is improvement, but every improvement is a change, correct me if I'm wrong.) Humans did not evolve this far by being better, but by socializing and cooperating. So I think we should move from herd to organization.

Non-relativistic Quantum Mechanics: Sakurai's Modern Quantum Mechanics

This is a textbook for graduate-level Quantum Mechanics. It's advantages over other texts, such as Messiah's Quantum Mechanics, Cohen-Tannoudji's Quantum Mechanics, and Greiner's Quantum Mechanics: An introduction is in it's use of experimental results. Sakurai weaves in these important experiments when they can be used to motivate the theoretical development. The beginning, using the Stern-Gerlach experiment to introduce the subject, is the best I have ever encountered.

I found this book very good as well. I want to add a comment, though.

If you start reading it, and you get lost, just stop reading that chapter and go to the next one. Read this book lightly at first, then start clarifying everything afterwards. Reading introduction of every chapter first is very clever.

What are the prerequisites for reading this? What level of mathematics and background of classical physics?

Comment author: Lu93 12 March 2015 03:24:46PM 2 points [-]

You need some solid Linear Algebra: Vector Space, dual vector space, unitary and hermitian matrices, eigenvectors and eigenvalues, trace... Mind that you should learn these things with mathematical approach, for example, vectors are elements of vector space which has certain axioms, and not 3D arrows, like pupils learn in school. Since book has this approach (matrix mechanics, rather than wave mechanics), you don't need too strong analysis, you can just trust that some things are working that way, but if you want to understand it fully, i recommend taking some analysis course as well, to be able to understand decomposition in eigenfunctions. Integrals and derivatives are MUST, however.

Ok, this thing is harder then it looked. Writing demands time and concentration, and I am not sure if i can explain things as good as they were explained to me.

I am absolutely sure it would be highly beneficial for people to understand basics of economics and finance, but I think I am not the right person to do this. So, I give up, and I will just recommend some literature/video lessons. I think i saw some book list on this forum, so, if you want to hear more about this stuff, head there.

Edit: TL;DR I made equivalent problem. It is sufficient and necessary. Prove: p(H causes destruction | H is Alive) < p(H causes destruction | H is Dead)

I have exams so I don't have enough time to do the whole process, as it should be done. I wanted to donate my thoughts and hope for someone else to do the job.

If you remember, we are not supposed to give solutions at once, we should talk about problem first. This includes gathering fair knowledge about all the mechanisms mentioned.

I see some people listed available objects, which could be used in open combat. Which is exactly what we should do, given that the problem is how to fight them. The problem is, however, not how to win the fight.

Now, I have to admit i haven't thought about the whole problem (I am not facing 37 Deathe-Eaters, true, but I am facing 3 exams next week), I focused on two things: Harry's mind, and Voldy's mind. I will deduce if Harry will actually try to defend himself.

These are my thoughts:

  • Voldy (V) wants to stop the prophesy. Prophesy says Harry will cause great destruction.
  • Harry (H) cannot change V's utility function.
  • V's utility function has high preference for this world not being destroyed.
  • V tried to maximize this function. (He showed he is quite "rational" up until now)

This is part where I imagined myself being V.

"H will cause great destruction. There is greater probability of him causing destruction, than his death causing destruction. Therefore i have to kill him. I just resurrected Hermione, so, someone can resurrect H. I have to stop that, so i will destroy his remnants."

  • H did the whole Unbreakable Vow thing => he is now practically the only human who has no options when it comes to destroying the world.
  • H's utility function is practically the same as V's utility function now. (Both V and H prefer world over H)

  • "There is a prophesy i will destroy the world. I don't want to cause destruction. Is probability ("i cause destruction" if "I am alive") greater than ("I cause destruction" if "I am dead")? Whatever probability is lower, i will do that. "* (He can't chose anymore, he sacrificed it

    H would not try to live if that would lead to greater probability of mass destruction. He would prefer himself dead over alive. (If he is rational he would do that, because his utility function is such.)

Now, let's see compare pA = p(H causes destruction | H is Alive) and pD = pp(H causes destruction | H is Dead)

Vow ensures that if there is even a minor risk of H's next step creating destruction, he would have to interrogate that risk, and avoid it if there really is such a possibility. With regard to this and H's cleverness, he could cause something destructive much easier while absent than while present. =>
pD>pA

Since I don't see EY killing Harry or being inconsistent, pD is probably indeed greater, whether or not my deduction has flaws.

On this deduction depends whether or not H will actually do something to defend himself. If he will defend himself, he might as well communicate all this to V and he will let him go, because V prefers no destruction over destruction.

Edit: formatting.

Did i fail in my reasoning here? Because if i didn't, it is of major importance, and if i did, well, it's not important at all, but i would still like to know where i failed.

On the other hand, I see people have been trying to isolate themselves, so, i suppose my comment got unnoticed because of that.
