After many tribulations, my astrobiology bloggery is back up and running using Wordpress rather than Blogger because Blogger is completely unusable these days.  I've taken the opportunity of the move to make better graphs for my old posts. 

"The Solar System: Why Earth?"

https://thegreatatuin.wordpress.com/2016/10/03/the-solar-system-why-earth/

Here, I try to look at our own solar system and what the presence of only ONE known biosphere, here on Earth, tells us about life and perhaps more importantly what it does not.  In particular, I explore what aspects of Earth make it special and I make the distinction between a big biosphere here on Earth that has utterly rebuilt the geochemistry and a smaller biosphere living off smaller amounts of energy that we probably would never notice elsewhere in our own solar system given the evidence at hand. 

Commentary appreciated.

Epistemic Status/Effort: I'm 85% confident this is a good idea, and that the broader idea is at least a good direction. Have gotten feedback from a few people and spend some time actively thinking through ramifications of it. Interested in more feedback.

TLDR:

1) When asking a group a question, i.e. "what do you think about X?", ask people to wait 12 seconds, to give each other time to think. If you notice someone else ask a question and people immediately answering, suggest people pause the conversation until people have had some time to think. (Probably specific mention "12 second rule" to give people a handy tag to remember)

2) In general, look for opportunities to improve or share social norms that'll help your community think more clearly, and show appreciation when others do so (i.e. "Epistemic Norms")

(this was originally conceived for the self-described "rationality" community, but I think is a good idea any group that'd like to improve their critical thinking as well as creativity.)

There are three reasons the 12-second rule seems important to me:

• On an individual level, it makes it easier to think of the best answer, rather than going with your cached thought.
• On the group level, it makes it easier to prevent anchoring/conformity/priming effects.
• Also on the group level, it means that people take longer to think of answers get to practice actually thinking for themselves

I said "hey, shouldn't we stop to each think first?" (this happens to be a thing my friends in NYC do). And I was somewhat surprised that the response was more like "oh, I guess that's a good idea" than "oh yeah whoops I forgot."

It seemed like a fairly obvious social norm for a community that prides itself on rationality, and while the question wasn't *super* important, I think its helpful to practice this sort of social norm on a day-to-day basis.

This prompted some broader questions - it occurred to me there were likely norms and ideas other people had developed in their local networks that I probably wasn't aware of. Given that there's no central authority on "good epistemic norms", how do we develop them and get them to spread? There's a couple people with popular blogs who sometimes propose new norms which maybe catch on, and some people still sharing good ideas on Less Wrong, effective-altruism.com, or facebook. But it doesn't seem like those ideas necessarily reach saturation.

Atrophied Skills

The first three years I spent in the rationality community, my perception is that my strategic thinking and ability to think through complex problems actually *deteriorated*. It's possible that I was just surrounded by smarter people than me for the first time, but I'm fairly confident that I specifically acquired the habit of "when I need help thinking through a problem, the first step is not to think about it myself, but to ask smart people around me for help."

Eventually I was hired by a startup, and I found myself in a position where the default course for the company was to leave some important value on the table. (I was working in an EA-adjaecent company, and wanted to push it in a more Effective Altruism-y direction with higher rigor). There was nobody else I could turn to for help. I had to think through what "better epistemic rigor" actually meant and how to apply it in this situation.

Whether or not my rationality had atrophied in the past 3 years, I'm certain that for the first time in long while, certain mental muscles *flexed* that I hadn't been using. Ultimately I don't know whether my ideas had a noteworthy effect on the company, but I do know that I felt more empowered and excited to improve my own rationality. 

I realized that, in the NYC meetups, quicker-thinking people tended to say what they thought immediately when a question was asked, and this meant that most of the people in the meetup didn't get to practice thinking through complex questions. So I started asking people to wait for a while before answering - sometimes 5 minutes, sometimes just a few seconds.

"12 seconds" seems like a nice rule-of-thumb to avoid completely interrupting the flow of conversation, while still having some time to reflect, and make sure you're not just shouting out a cached thought. It's a non-standard number which is hopefully easier to remember.

(That said, a more nuanced alternative is "everyone takes a moment to think until they feel like they're hitting diminishing returns on thinking or it's not worth further halting the conversation, and then raising a finger to indicate that they're done")

Meta Point: Observation, Improvement and Sharing

The 12-second rule isn't the main point though - just one of many ways this community could do a better job of helping both newcomers and old-timers hone their thinking skills. "Rationality" is supposed to be our thing. I think we should all be on the lookout for opportunities to improve our collective ability to think clearly. 

I think specific conversational habits are helpful both for their concrete, immediate benefits, as well as an opportunity to remind everyone (newcomers and old-timers alike) that we're trying to actively improve in this area.

I have more thoughts on how to go about improving the meta-issues here, which I'm less confident and will flesh out in future posts.

30 years ago, the Cold War was raging on. If you don’t know what that is, it was the period from 1947 to 1991 where both the U.S and Russia had large stockpiles of nuclear weapons and were threatening to use them on each other. The only thing that stopped them from doing so was the knowledge that the other side would have time to react. The U.S and Russia both had surveillance systems to know of the other country had a nuke in the air headed for them.

On this day, September 26, in 1983, a man named Stanislav Petrov was on duty in the Russian surveillance room when the computer notified him that satellites had detected five nuclear missile launches from the U.S. He was told to pass this information on to his superiors, who would then launch a counter-strike.

He refused to notify anyone of the incident, suspecting it was just an error in the computer system.

No nukes ever hit Russian soil. Later, it was found that the ‘nukes’ were just light bouncing off of clouds which confused the satellite. Petrov was right, and likely saved all of humanity by stopping the outbreak of nuclear war. However, almost no one has heard of him.

We celebrate men like George Washington and Abraham Lincoln who win wars. These were great men, but the greater men, the men like Petrov who stopped these wars from ever happening - no one has heard of these men.

Let it be known, that September 26 is Petrov Day, in honor of the acts of a great man who saved the world, and of who almost no one has heard the name of.

My 11-year-old son wrote and then read this speech to his six grade class.

There are several well-known games in which the pareto optima and Nash equilibria are disjoint sets.
The most famous is probably the prisoner's dilemma.  Races to the bottom or tragedies of the commons typically have this feature as well.

I proposed calling these inefficient games.  More generally, games where the sets of pareto optima and Nash equilibria are distinct (but not disjoint), such as a stag hunt could be called potentially inefficient games.

It seems worthwhile to study (potentially) inefficient games as a class and see what can be discovered about them, but I don't know of any such work (pointers welcome!)

Once in a while, I learn something about a seemingly unrelated topic - such as freediving - and I take away some trick that is well known and "obvious" in that topic, but is generally useful and NOT known by many people outside. Case in point, you can use equalization techniques from diving to remove pressure in your ears when you descend in a plane or a fast lift. I also give some other examples.

Ears

Reading about a few equalization techniques took me maybe 5 minutes, and after reading this passage once I was able to successfully use the "Frenzel Maneuver":

The technique is to close off the vocal cords, as though you are about to lift a heavy weight. The nostrils are pinched closed and an effort is made to make a 'k' or a 'guh' sound. By doing this you raise the back of the tongue and the 'Adam's Apple' will elevate. This turns the tongue into a piston, pushing air up.

Hiccups

A few years ago, I started regularly doing deep relaxations after yoga. At some point, I learned how to relax my throat in such a way that the air can freely escape from the stomach. Since then, whenever I start hiccuping, I relax my throat and the hiccups stop immediately in all cases. I am now 100% hiccup-free.

Stiff Shoulders

I've spent a few hours with a friend who is doing massage, and they taught me some basics. After that, it became natural for me to self-massage my shoulders after I do a lot of sitting work etc. I can't imagine living without this anymore.

Other?

If you know more, please share!

Hi, I'm an entrepreneur looking for a startup idea.

In my experience, the reason most startups fail is because they never actually solve anyone's problem. So I'm cheating and starting out by identifying a specific person with a specific problem.

So I'm asking you, what's the most annoying part of your life/job? Also, how much would you pay for a solution?

MIRI is running an AMA on the Effective Altruism Forum tomorrow (Wednesday, Oct. 11): Ask MIRI Anything. Questions are welcome in the interim!

Nate also recently posted a more detailed version of our 2016 fundraising pitch to the EA Forum. One of the additions is about our first funding target:

We feel reasonably good about our chance of hitting target 1, but it isn't a sure thing; we'll probably need to see support from new donors in order to hit our target, to offset the fact that a few of our regular donors are giving less than usual this year.

The Why MIRI's Approach? section also touches on new topics that we haven't talked about in much detail in the past, but plan to write up some blog posts about in the future. In particular:

Loosely speaking, we can imagine the space of all smarter-than-human AI systems as an extremely wide and heterogeneous space, in which "alignable AI designs" is a small and narrow target (and "aligned AI designs" smaller and narrower still). I think that the most important thing a marginal alignment researcher can do today is help ensure that the first generally intelligent systems humans design are in the “alignable” region. I think that this is unlikely to happen unless researchers have a fairly principled understanding of how the systems they're developing reason, and how that reasoning connects to the intended objectives.

Most of our work is therefore aimed at seeding the field with ideas that may inspire more AI research in the vicinity of (what we expect to be) alignable AI designs. When the first general reasoning machines are developed, we want the developers to be sampling from a space of designs and techniques that are more understandable and reliable than what’s possible in AI today.

In other news, we've uploaded a new intro talk on our most recent result, "Logical Induction," that goes into more of the technical details than our previous talk.

Politics

The LessWrong survey has a very involved section dedicated to politics. In previous analysis the benefits of this weren't fully realized. In the 2016 analysis we can look at not just the political affiliation of a respondent, but what beliefs are associated with a certain affiliation. The charts below summarize most of the results.

Political Opinions By Political Affiliation

Miscellaneous Politics

There were also some other questions in this section which aren't covered by the above charts.

Calibration And Probability Questions

Calibration Questions

I just couldn't analyze these, sorry guys. I put many hours into trying to get them into a decent format I could even read and that sucked up an incredible amount of time. It's why this part of the survey took so long to get out. Thankfully another LessWrong user, Houshalter, has kindly done their own analysis.

All my calibration questions were meant to satisfy a few essential properties:

1. They should be 'self contained'. I.E, something you can reasonably answer or at least try to answer with a 5th grade science education and normal life experience.
2. They should, at least to a certain extent, be Fermi Estimable.
3. They should progressively scale in difficulty so you can see whether somebody understands basic probability or not. (eg. In an 'or' question do they put a probability of less than 50% of being right?)

At least one person requested a workbook, so I might write more in the future. I'll obviously write more for the survey.

Probability Questions

Probability questions is probably the area of the survey I put the least effort into. My plan for next year is to overhaul these sections entirely and try including some Tetlock-esque forecasting questions, a link to some advice on how to make good predictions, etc.

Futurology

This section got a bit of a facelift this year. Including new cryonics questions, genetic engineering, and technological unemployment in addition to the previous years.

Cryonics

Interestingly enough, of those who think it will work with enough confidence to say 'yes', only 14 are actually signed up for cryonics.

sqlite> select count(*) from data where CryonicsNow="Yes" and Cryonics="Yes - signed up or just finishing up paperwork";

14

sqlite> select count(*) from data where CryonicsNow="Yes" and (Cryonics="Yes - signed up or just finishing up paperwork" OR Cryonics="No - would like to sign up but unavailable in my area" OR "No - would like to sign up but haven't gotten around to it" OR "No - would like to sign up but can't afford it");

34

LessWrongers seem to be very bullish on the underlying physics of cryonics even if they're not as enthusiastic about current methods in use.

The Brain Preservation Foundation also did an analysis of cryonics responses to the LessWrong Survey.

Singularity

Obviously it's a bit hard to see without filtering out the uber-large answers, but the median doesn't seem to have changed much from the 2014 survey.

Genetic Engineering

Well that's fairly overwhelming.

I find it amusing how the strict "No" group shrinks considerably after this question.

This question is too important to just not have an answer to so I'll do it manually. Unfortunately I can't easily remove the 'excluded' entries so that we're dealing with the exact same distribution but only 13 or so responses are filtered out anyway.

sqlite> select count(*) from data where GeneticImprovement="Yes";

1100

>>> 1100 + 176 + 262 + 84
1622
>>> 1100 / 1622
0.6781750924784217

67.8% are willing to genetically engineer their children for improvements.

These numbers go about how you would expect, with people being progressively less interested the more 'shallow' a genetic change is seen as.

All three of these seem largely consistent with peoples personal preferences about modification. Were I inclined I could do a deeper analysis that actually takes survey respondents row by row and looks at correlation between preference for ones own children and preference for others.

Technological Unemployment

We can use this as an overall measure of worry about technological unemployment, which would seem to be high among the LW demographic.

Interesting question that would be fun to take a look at in comparison to the estimates for the singularity.

Fairly overwhelming consensus, but with a significant minority of people who have a dissenting opinion.

The plurality of worries are about elites who refuse to share their wealth.

Existential Risk

Significantly more people worried about Nuclear War than last year. Effect of new respondents, or geopolitical situation? Who knows.

Charity And Effective Altruism

Charitable Giving

This table is interesting given the recent debates about how much money certain causes are 'taking up' in Effective Altruism.

Effective Altruism

The distribution given by the 2014 survey results does not sum to one, so it's difficult to determine if Effective Altruism's membership actually went up or not but if we take the numbers at face value it experienced an 11.13% increase in membership.

Same issue as last, taking the numbers at face value community participation went up by 5.727%

Wowza!

Effective Altruist Anxiety

There's an ongoing debate in Effective Altruism about what kind of rhetorical strategy is best for getting people on board and whether Effective Altruism is causing people significant moral anxiety.

It certainly appears to be. But is moral anxiety effective? Let's look:

Sample Size: 244
Average amount of money donated by people anxious about EA who aren't EAs: 257.5409836065574

Sample Size: 679
Average amount of money donated by people who aren't anxious about EA who aren't EAs: 479.7501384388807

Sample Size: 249 Average amount of money donated by EAs anxious about EA: 1841.5292369477913

Sample Size: 314
Average amount of money donated by EAs not anxious about EA: 1837.8248407643312

It seems fairly conclusive that anxiety is not a good way to get people to donate more than they already are, but is it a good way to get people to become Effective Altruists?

Sample Size: 1685
P(Effective Altruist): 0.3940652818991098
P(EA Anxiety): 0.29554896142433235
P(Effective Altruist | EA Anxiety): 0.5

Maybe. There is of course an argument to be made that sufficient good done by causing people anxiety outweighs feeding into peoples scrupulosity, but it can be discussed after I get through explaining it on the phone to wealthy PR-conscious donors and telling the local all-kill shelter where I want my shipment of dead kittens.

EA appears to be doing a pretty good job of getting people to like them.

Interesting Tables
