Thank you! I didn't know about quantified intuitions. I'm checking it out now!

I suppose this is why the comparison with Duolingo came to mind: teaching rationality is akin to teaching a whole language. We need lots of aspects of it, not just one. 

Also (now I’m just introducing another thing here), ideally it would be in a style that is as friendly and non-threatening as possible—again, like Duolingo’s vibe—though obviously it couldn’t be as entirely neutral as learning a language. To be effective, it would need to leave learners feeling supported rather than shamed. 

Again I think of HPMOR as a great example of all of this: it covers lots of different rationality skills and has a reader-friendly vibe.

The app’s hook might be something like “Learn to think like a scientist” or “level up your decision making skills” or “hack your own brain.” (lol, idk)

But to answer your question, if I had to pick one rationality skill that seemed most important to me personally, the one that comes to mind seems like a meta-rationality skill, which working on lots of other various rationality skills would also serve: building the habit—through training/practice—of noticing, questioning, and testing one’s beliefs.

I look forward to your site! 

To answer your question: similarly to how HPMOR presents rationality skills in a learning format (fiction) that is accessible to a general audience, I would love for there to be an app that, like Duolingo, teaches skills and concepts in small, guided practice sessions with little rewards for completion. 

For context: I’m not in Silicon Valley surrounded by people who are already really smart and interested in rational thinking. I’m in the middle of West Virginia, surrounded by right-wing tribalism and fundamentalist evangelicalism, out of which I have clawed my way. We need all the easy, accessible help we can get with learning rationality. (HPMOR has changed my life!)

Has anyone yet created a free app that would be like Duolingo but for rationality, to teach skills such as logical reasoning, recognizing & adjusting for cognitive biases, and looking for hypothesis falsification tests instead of confirmation? If not, can you smart tech people here please make one?! 

Inspired by you guys (LessWrong), I'm trying out a thing: a free forum website called Kindness Village, which is intended to be a safe space for people to connect and support each other. This feels like a Thing I Can Do (among other things I'm already doing) in response to my ongoing feelings of dismay about current events. I want to make a place where people can not only make authentic connections and be supported--bypassing chitchat and social media blather--but also where, theoretically, people from both sides of the political spectrum can connect in a bridge-building, tribe-expanding way.

I have no tech skills to speak of, but I did my best as of now (I just made it). Would anyone here like to come join in and lend your intelligent voice to this project? I haven't announced it on my various channels yet; you're first because you inspired me! The URL is kindnessvillage.org (not .com because that one was taken).

Add my vote too!!

Oh, I see. Thank you very much.

Hello, I'm new here and still working on reading the Sequences and the other amazing content on here; hopefully then I'll feel more able to join in some of the discussions and things. For now, I have what I'm sure is an embarrassingly basic question, but I can't find an answer on here anywhere and it keeps distracting me from focusing on the content: would someone please tell me what's the deal with the little degree symbols after some links but not others?

Thank you in advance, and warm regards to you all.
