maybe we can (at least at the beginning of getting over it) switch the self-talk that comes after noticing procrastination (and many times just makes us miserable and isn't sufficient at changing our behavior), with a simple coin flip - if heads, i stop procrastinating, if tails, I'm free to continue guilt-free. and make it a TAP: "When ever i notice that i currently procrastinate, i flip a coin"

Though look at this clip out of the documentary "no more boys and girls", showing how when adults think babies are the opposite sex than they actually are, they give them toys that match the stereotype.

Thing is, even little babies have environmental influence (There's even prenatal environmental influence), so just showing behavioral changes in babies doesn't cut it, that's why i always wonder how studies suggesting genetic influence are done.

(searched for LW posts on documentaries and found this one, hopefully commenting on old comments is well received :) )

Are there documentaries on rationality?

thanks for this post! I have read the 7 habits a few years ago but didn't remember that part at all (not even now that you mention). so not only did you remind me, you also made it better :)

I actually like your version before the simplification. for example, i think the "shouldn't" can be good, for when we want a strong reminder/pledge to ourselves to break some habit. there are also many people who suggest actually making a "NOT to do list", so if that is valuable advice, than your model will take it in.

you made me think of a feature i think can be great, that when someone gives a down-vote to a post the site automatically prompts him to comment. another idea is that you'll only be able to make a strong down-vote if you comment, but I'm not to sure about that.

As someone new to the community i can testify that i probably would have had more motivation to write if i gotten more comments and discussion. especially since, at least for me, the things i think to publish aren't necessarily very polished ideas, but things i would like to get input on.

I think trying to predict human behavior, and developing ways to do it best, is a great exercise, and one that can also have immediate benefits (being better at predicting what people will do makes your social skills better).

This can also be taken as a full project of rationality, doing scholarship (science of people), using math and probability (maybe even inventing your own algorithms), gathering, organizing, and analyzing data (like personality types of people you know and what can they tell you about them)...

Please, don't undermine yourself :)

As Scott Alexander said - the LessWrong survey found the lowest percentile in this community to 85th percentile of the general population. that means one with the lowest score here is still quite smart.

Also, take a look at dunning-Kruger effect, not because the inadequate rate themselves high, but because "the best performers will systematically underestimate how good they are, by about 15 percentile points." You can also read around Yudkowsky on modesty.

And statistically speaking, i think i should believe (due to base rate) that you're in the mean/median of intelligence of this community. than, due to your modesty, only put you higher.

(Hopefully i haven't pressed this point to much, it just saddens me to people under-confident in themselves. i feel that way too sometimes, so i want to help others when i can)

My question: is there any feedback you can give on this idea

Yes - Do it! go for it! have fun! you don't have to be the most adequate, and you won't need to fake adequacy.

Other then that, i think starting with hammer time can be a great way to start if you don't feel confident enough to do otherwise, and you can invite people from the community and ask them questions. i think that's a good starting point :)

basically you say that pretty much all rationality skills (Logic, knogledge of biases and heuristics, etc...) are needed or beneficial to know how not to make mistakes while handling the data - right?

I began going through some basics on khan academy, and plan to then learn statistics and probability there.

i think I'll wait with learning data analysis at least until after that.

I would say that logic is actually more important than math

What if first, you just calculate the most beneficial actions you can take (like Scott did), and after that asses each of those using something like piers steel's procrastination equation? then you know which one you're most likely to achieve, and can can choose more wisely.

also, doing the easiest first can sometimes be a good strategy to achieve all of them, steel calls it a success spiral, where you succeed time after time and it increases your motivation.

yeah i wrote a line at the end about pollution in general, but talked about CO2 cause that can be emitted just from the breathing process. and also a lot of time CO2 is used as a general metric for pollution, even if it's not the only substance.

the office machine to remove CO2 is really quite interesting actually, it's the first good (or any) idea i heard that makes it worthy for business . i wonder how much effect it can have on the general environment if it were put into practice.

they restructured the rhythm and pacing and added vivid turns of phrase, while keeping all the important content in place. I still haven't worked out exactly how they did it, or what principles lie behind the changes, but suddenly it sounded like a more graceful, alive voice was making my argument.

I'll just put this great quote here (which is a great explanation for at least one thing they might have done, depends on whether you did that already)

“This sentence has five words. Here are five more words. Five-word sentences are fine. But several together become monotonous. Listen to what is happening. The writing is getting boring. The sound of it drones. It’s like a stuck record. The ear demands some variety. Now listen. I vary the sentence length, and I create music. Music. The writing sings. It has a pleasant rhythm, a lilt, a harmony. I use short sentences. And I use sentences of medium length. And sometimes, when I am certain the reader is rested, I will engage him with a sentence of considerable length, a sentence that burns with energy and builds with all the impetus of a crescendo, the roll of the drums, the crash of the cymbals–sounds that say listen to this, it is important.”

i know Kialo, it's extremely different. Kialo is a debate platform with a nice sorting and ranking system. it doesn't have any algorithm to find what's "right", it just shows "both sides of the argument".

I don't think that anybody who learned a bit about cognitive biases or epistemology would build that website in such a way (each side gets an equal representation, even though they're not epistemically equal. and i remember a study that showed that pros and cons list don't work to change peoples minds, cause they allow them to very easily fall into confirmation bias.

The hopeful thing about Asch's conformity experiments is that a single dissenter tremendously drove down the rate of conformity, even if the dissenter was only giving a different wrong answer. (...) Being a voice of dissent can bring real benefits to the group.  But it also (famously) has a cost.  And then you have to keep it up.  Plus you could be wrong.

so a good thing to do can be to voice a disagreement with the group (even if you don't know the answer), in order to give someone else the courage to speak the truth, and then support whatever it is he said (assuming for some reason you still can't know the answer)?

that's assuming that other people aren't likely to speak up whatever just so someone else will speak the truth, so it's probable that if someone defy the group he has a good reason to think he's right.

sorry, i made a communication error. "הַתְרָצָה" is the other word for rationalization in Hebrew, it stems from the word for excuse which is "תירוץ".

Comment by yoav-ravid on Rationalization · 2019-01-07T07:39:31.812Z · score: 3 (2 votes) · LW · GW

in Hebrew there's a synonym for rationalization that stems from the word "excuse" ("הַתְרָצָה"). i think it's quite fitting, as that's basically the process. you decide on a conclusion and excuse you way backward from it so it seems rational.

what do you think?

I'm not very good in English so I'm not sure, if we create a word for it that stems from excuse, what it would be - have any suggestions?

this is something i thought of, that rationality shouldn't have any axioms, but then wasn't really sure that it hadn't (cause it felt to me that it does). so i asked the question to see what people think.

for example, how do you view this phrase "what could be destroyed by the truth should be"? is it an axiom?
