liked the video, i think you improved from the first :)

Specifically -

I think the thumbnail is better, more eye-catchy and likely to get clicked.

the title is better, i think many people would wonder "huh, why do smart people become stupid?".


A few points for improvement -

the intro was nice, but not really attention grabbing.

You used a lot of clips of people talking, which was good, i think you could mix it up a bit with some audio from them here and there, can make the video a bit more fun (and even give examples).

The subscribe thing at the end was a jump scare, not so nice.

You should engage with commenters, Either liking their comments or replying.


all in all - I think you're doing a good job, and i subscribed, keep going :)

Comment by yoav-ravid on Meta analysis of Writing Therapy · 2019-09-08T11:22:00.060Z · score: 1 (1 votes) · LW · GW

I had the idea that journalism can be helpful and beneficial to rationalists, and thought to write about it, but i first looked to see if someone did it already.

This post was really helpful, though i found it only through a different post since it didn't have the keywords "journaling" and "diary".

Here's another benefit that isn't discussed and relevant specifically to rationality:

We know that our memory is far from perfect, and that whenever we remember something we change the memory a little, and maybe add after the fact analysis to it.

long term journaling gives you a window into how you thought in the past, and how your thinking has changed.

I think it would also be very valuable for someone who's just staring out with rationality, to start a journal and as part of it track his journey with rationality. We're all families with how many of the ideas in the sequences feel obvious after sometime getting used to them. a journal would record and remind you how it was for you to first grapple with these new ideas.

Another benefit is noticing patterns and principles:

I noticed in my life that many times after some events (meaningful, happy, sad, important, etc.), i note a principle to myself, a lesson from it. but also many times when it happens, i notice that i already "noted" this principle to myself, but since i haven't written it or talked with someone about it i forgot it. not making the smae mistakes over and over again is a large part of rationality, being able to review such moments and your thoughts on them at the moment would be very helpful.

I would put a lot of focus on Akrasia early on. to me, Akrasia seems like the "denominator of rationality". no matter how rational you are, if you are akratic, your behavior won't be rational. for example, if you follow through on just 1/10 best judgements you have, you can never fulfill more than 10% of your rationality potential.

I would then add a section that deals with applying rationality to "limiting beliefs" (close to the self development), things that if you stop believing in it won't just be rewarding because it's the truth, but will bring instant improvement to your life. one example is irrational fears - life fear of rejection and failure.

Another thing here would be the importance of practice. focusing on going out there and trying to do stuff, then later also using your rationality specific skills to develop better strategy. practice could be rejection therapy, habit forming, talking to strangeness, even pickup*. the important thing about these are that they are highly actionable, traceable (it's easy to now if you're making progress), and give a lot of value back.

*I know pick up is touchy subject on LW. I'm talking about the non creepy pick-up, whether for man or woman, where they train on being better with the other and sex. not manipulating and using the other sex.


I have some more thoughts that right now are less concrete, i will probably edit this answer later.

I'd have to say the harder version is quite cool as well.

Yes, it's a good point, that it's a pattern that will pop up all over the place regardless. so the question is, if no one formally stated it (i.e identified it as a common pattern), how would it look? what scientific discoveries wouldn't have been made? what wouldn't have been invented? what would we have believed to be true that's actually false? what bad decisions would we make? what good decision have we made because of it that we would have been able to make without it?

all examples would do, though the more impactful the better :)

But if we have to pick an age, it should be the SAME as other adult responsibilities

Why that?

"Cortical white matter increases from childhood (~9 years) to adolescence (~14 years), most notably in the frontal and parietal cortices.[8] Cortical grey matter development peaks at ~12 years of age in the frontal and parietal cortices, and 17 years in the temporal lobes (with the superior temporal cortex being last to mature) for women and they have reached full maturity at age 16-17. For men, they become fully mature at age 18. In terms of grey matter loss, the sensory and motor regions mature first, followed by other cortical regions.[8] Human brain maturation continues to around 20[9] to 25[10] years of age."

Pattern, i miscommunicated my question, i didn't mean to ask about a Bayesian agent in the sense of a rational agent. just what is the mathematical result from plucking certain numbers into the equation.

I am well aware now and before the post, that a rational agent won't have a 100% prior, and won't find evidence equal to a 100%, that wasn't where the question stemmed from.

Comment by yoav-ravid on The Politics of Age (the Young vs. the Old) · 2019-03-24T12:42:40.089Z · score: 8 (4 votes) · LW · GW

correlation between improved-decision-making-skills, and moving from being 16 to 18 years old, seems somewhat weak and certainly not as strong as other predictors (education, self-reflection, IQ, etc.). also, it bears asking, why these certain ages - if 16 then why not 15? and if not 16, then why stay on 18 and not move to 19? cause AFAIK, the brain (frontal cortex) stops developing at age 24-25.

I grew up in a democratic school, my experience was that kids were far better at making decisions than the general population gave them credit for. and that it depended more on factors other than age.

anyone who says we should not lower the voting age for reasons of decreased decision making skills, should really ask himself why age based restrictions are OK, and other interventions that are sometimes suggested aren't (like passing certain tests).

This math is exactly why we say a rational agent can never assign a perfect 1 or 0 to any probability estimate.

Yes, of course. i just thought i found an amusing situation thinking about it.

You're not confused about a given probability, you're confused about how probability works.

nice way to put it :)

I think i might have framed the question wrong. it was clear to me that it wouldn't be rational (so maybe i shouldn't have used the term "Bayesian agent"). but it did seem that if you put the numbers this way you get a mathematical "definition" of "infinite confusion".

Comment by yoav-ravid on Can Bayes theorem represent infinite confusion? · 2019-03-22T20:07:11.037Z · score: 1 (1 votes) · LW · GW

I see. so -

If P(H) = 1.0 - ϵ1

And P(E|H) = 0 + ϵ2

Then it equals "infinite confusion".

Am i correct?

and also, when you use epsilons, does it mean you get out of the "dogma" of 100%? or you still can't update down from it?

And what i did in my post may just be another example of why you don't put an actual 1.0 in your prior, cause then even if you get evidence of the same strength in the other direction, that would demand that you divide zero by zero. right?

Thanks for the answer! i was somewhat amused to see that it ends up being a zero divided by zero.

Does the ratio between 1epsilon over 2epsilon being undefined means that it's arbitrarily close to half (since 1 over two is half, but that wouldn't be exactly it)? or means that we get the same problem i specified in the question, where it could be anything from (almost) 0 to (almost) 1 and we have no idea what exactly?

Yup, that was the idea. a strict hierarchy wouldn't be an accurate map of the communities landscape. I think you would probably get some really weird nesting in some places (especially if we're talking about individual users), but as long as it works and is intuitive to the user, it's fine.

Can a strategy against blackmail be to reveal the information yourself?

If you don't want to comply (pay), and you believe Alice will follow on her threat, can you minimize harm by being faster and revealing the information yourself?

You can also gain yourself some reputation by seeming honest, and to take away any status Alice might have gotten from exposing you. Alice can't put you in a bad light for "stealing" it from her, cause then she admits to blackmail.

and lastly - who's gonna try to blackmail someone who just makes it past them and publishes it themselves?

So, an action coordination website should be able to phrase actions in four words?

This idea seems interesting, i'd love to see it somehow more formulated.

Do shorter kickstarter descriptions get funded more?

Do protest events on Facebook which have a shorter description get more attendees?

It probably also depends on personality - if you want to coordinate people who are high in contentiousness, you may need more words. for low contentiousness, less words. and if you want both, than you need to give a clear 4-word heading, and a bunch of nuance below.

1. I'd love to see that. surely, it's not probable that a funding campaign which uses google forms instead of KickStarter would be better off, right? i think we have concluded this line of thought - i'm skeptical, and you don't see a reason why not.

Though, again, 150 people attending a LW meeting is far from the type of coordination this site will be for. i'm not blind to the fact we have better coordination tools than going door-to-door and talking to people - i say that the coordination tools we have today aren't sufficient for more complicated coordination - where there are a lot of people involved, several types of actors, many incentives, etc...

2. maybe you're right. still, it's worth a try and a little effort :)

3. that wasn't my reaction for doing an MVP, but reasoning for a platform being good, and saying that google forms isn't a platform (more specifically, it isn't a platform for coordinating action, but a more general platform, so it can't be trusted as one)

Could you fund a video game with google forms? (assuming it has a PayPal widget, if needed)

There are three main problems i see with google forms.

First, i think it'll be harder to get people on board, much harder to get many people on board, and much harder still to do it consistently.

Second, there's probably a high value to a system that ensures (or at least makes it more probable) that someone who obligated to take an action actually took it. if you don't have such a system, then whatever you did, you're arguably almost in the starting same position. everyone might still be suspicious that no one else will take action, and so nobody will take it.

the third connects to the second, but may be different enough - A platform could gain trust. not only would i not fund a video game through google forms, i may not even want to fund it through certain kickstarter-like sites, cause i don't trust them as i trust kickstarter.

That's not getting into functionality that to me seems important.

The post was very clear to understand, and the graphics were spot-on (would even be fine to leave just the graphic trees without the text trees).

I actually done something very similar to that a few days ago. I wrote down on a peace of paper a few things i knew are important to me, and than analyzed them - thought how do they relate to each other, what might be higher than them, and how might i break them down. than i also connected each breakdown to other higher level goals that could be benefited from achieving it.

After doing it i got to a conclusion that there are two shorter-term goals that are most beneficial for me right now.

This is basically a 'technical' explanation of the "start with the end in mind" principle, which i try to use often. hopefully you gave me another way to think about it which will be useful.
