Awesome! This strikes me as a very good thing, especially with your suggested social norms. I have 3 additional suggestions, though:

1. Add a social norm where commenters make short summaries, or quote a couple sentences of new info, without the fluff. The title of the link serves much the same purpose, and gives readers enough info to decide whether or not to click through. This is standard practice on the more intellectual subreddit, since they already have the background context and knowledge that 90% of the article is spent explaining.

2. Add a social norm where the best comments get linked to. I enjoy Yvain's SSC posts, and the comments section often contains some gems, but digging through all of them to find the gems is tedious. I intend to quote or rephrase gems when I find them, and link to them in comments here.

3. Maybe we should have subreddits on LW. I'm not sure about this one. Tags serve some of the same purposes, so perhaps what would be ideal would be to subscribe and unsubscribe from tags you're interested in. However, just copying the Reddit code for subreddits would be simpler. It would divide up the community though, so probably not desirable while we're still small.

I don't know if this is lesswrong material, but I found it interesting. Cities of Tomorrow: Refugee Camps Require Longer-Term Thinking

“the average stay today in a camp is 17 years. That’s a generation.” These places need to be recognized as what they are: “cities of tomorrow,” not the temporary spaces we like to imagine. “In the Middle East, we were building camps: storage facilities for people. But the refugees were building a city,” Kleinschmidt said in an interview. Short-term thinking on camp infrastructure leads to perpetually poor conditions, all based on myopic optimism regarding the intended lifespan of these places.

Many refugees may never be able return home, and that reality needs to be realized and incorporated into solutions. Treating their situation as temporary or reversible puts people into a kind of existential limbo; inhabitants of these interstitial places can neither return to their normal routines nor move forward with their lives..

From City of Thorns:

The UN had spent a lot of time developing a new product: Interlocking Stabilized Soil Blocks (ISSBs), bricks made of mud, that could be used to build cheap houses in refugee camps. It had planned to build 15,000 such houses in Ifo 2 but only managed to construct 116 before the Kenyan government visited in December 2010 and ordered the building stopped. The houses looked too much like houses, better even than houses that Kenyans lived in, said the Department for Refugee Affairs, not the temporary structures and tents that refugees were supposed to inhabit.

From reddit:

Peru had an uprising in the 1980s in which the brutality of the insurgents, the Sendero Luminoso, caused mass migration from the Andes down to the coast. Lima's population grew from perhaps a million to its current 8.5 million in a decade. This occurred through settlements in pure desert, where people lived in shacks made of cardboard and reed matting. These were called "young villages", Pueblos Jóvenes.

Today, these are radically different. Los Olivos is now a lower-middle-class suburb, boasting one of the largest shopping malls in South America, gated neighborhoods, mammoth casinos and plastic surgery clinics. All now have schools, clinics, paved roads, electricity and water; and there is not a cardboard house in sight. (New arrivals can now buy prefab wooden houses to set up on more managed spaces, and the state runs in power and water.)

Zaatari refugee camp in Jordan, opened 4 years ago seems to be well on it's way to becomming a permanent city. It has businesses, permanent structures, and it's own economy.

This is really awesome and could change the fate of lesswrong. I really think this will bring people back (at least more than any other easy to implement change.) I personally expect to spend more time here now, at least.

One thing to take note of is that lesswrong, by default, sorts by /new. As the volume of posts increases, it may be necessary to change the default sort to /hot or /top/?t=week. Especially if you want it to be presentable to newcomers or even old timers coming back to the site, you want them to see the best links first.

I was at the vet a while back; one of my dogs wasn't well (she's better now). The vet took her back, and after waiting for a few minutes, the vet came back with her.

Apparently there were two possible diagnosis: let's call them x and y, as the specifics aren't important for this anecdote.

The vet specifies that, based on the tests she's run, she cannot tell which diagnosis is accurate.

So I ask the vet: which diagnosis has the higher base rate among dogs of my dog's age and breed?

The vet gives me a funny look.

I rephrase: about how many dogs of my dog's breed and age get diagnosis x versus diagnosis y, without running the tests you did?

The vet gives me another funny look, and eventually replies: that doesn't matter.

My question for Lesswrong: Is there a better way to put this? Because I was kind of speechless after that.

When people say "a dollar was worth more 50 years ago", you don't reply "nuh uh, a dollar has always been worth exactly one dollar."

Yes, but "a dollar is now worth $x" where x is different from 1 is still meaningless unless you specify you're talking about today's dollar vs some other year's dollar specifically.

First of all, IQ tests aren't designed for high IQ, so there's a lot of noise there and this is probably mainly noise.

Indeed. If an IQ test claims to provide accurate scores outside of the 70 to 130 range, you should be suspicious.

There are so many misunderstandings about IQ in the general population, ranging from claims like "the average IQ is now x" (where x is different from 100), to claims of a famous scientist having had an IQ score over 200, and claims of "some scientists estimating" the IQ of a computer, an animal, or a fictional alien species. Or things as simple as claiming to calculate an IQ score based on a low number (usually less than 10) of trivia questions about basic geography and names of celebrities.

Google car also uses machine learning. That still doesn't mean that it tries to emulate a human driver. The article doesn't say that the car predicts what a human driver would do.

How do you enforce that the Ai should "try to drive with as little risk as possible"?

There's the example of the Google car waiting for the woman in the wheelchair who chased ducks. That's behavior you get from the way Google algorithm cares about safety that you wouldn't get from emulating human drivers.

Replace "give human heroin" with "replace the human with another being whose utility function is easier to satisfy, like a rock", and this conclusion seems sort of trivial. It has nothing to do with whether or not humans are rational. Heroin is an example of a thing that modifies our utility functions. Heroin might as well replace the human with a different entity, that has a slightly different utility function.

In fact I don't see how the human in this situation is being irrational at all. Not doing heroin unless you are already addicted seems like a reasonable behavior.

It's not my impression that self driving cars simply try to copy what a human does in any case. The AI don't violate speed limits and generally try to drive with as little risk as possible. Humans drive very differently.

Juergen Schmidhuber has a theory of artificial curiosity. His theory proposes that seeking confusion is actually a good thing. Agents that seek out situations where surprising things happen, put their internal models to the test and learn the most. And that's all curiosity is.

Amazement is just a form of curiosity. People who are interested in AlphaGo have had their internal models of AI progress challenged, and are updating them.
