## Deserving trust / grokking Newcomb’s problem

Summary: This is a tutorial on how to properly acknowledge that your decision heuristics are not local to your own brain, and that as a result, it is sometimes normatively rational for you to act in ways that are deserving of trust, for no other reason other than to have deserved that trust in the past.

Related posts: I wrote about this 6 years ago on LessWrong (“Newcomb’s problem happened to me”), and last year Paul Christiano also gave numerous consequentialist considerations in favor of integrity (“Integrity for consequentialists”) that included this one. But since I think now is an especially important time for members of society to continue honoring agreements and mutual trust, I’m giving this another go. I was somewhat obsessed with Newcomb’s problem in high school, and have been milking insights from it ever since. I really think folks would do well to actually grok it fully.

You know that icky feeling you get when you realize you almost just fell prey to the sunk cost fallacy, and are now embarrassed at yourself for trying to fix the past by sabotaging the present? Let’s call this instinct “don’t sabotage the present for the past”. It’s generally very useful.

However, sometimes the usually-helpful “don’t sabotage the present for the past” instinct can also lead people to betray one another when there will be no reputational costs for doing so. I claim that not only is this immoral, but even more fundamentally, it is sometimes a logical fallacy. Specifically, whenever someone reasons about you and decides to trust you, you wind up in a fuzzy version of Newcomb’s problem where it may be rational for you to behave somewhat as though your present actions are feeding into their past reasoning process. This seems like a weird claim to make, but that’s exactly why I’m writing this post.

## Start following conservative media, and remember how agreements between people and states actually work

Dear liberal American friends: please pair readings of liberal media with viewings of Fox news or other conservative media on the same topics. This will take work. They will say things you disagree with, using words you are unfamiliar with. You’ll have to stop scrolling down on Facebook and actively google phrases like “Trump executive order to protect America.” That may sound hard, but the integrity of your country depends on you doing it.

You’ve probably heard about the President’s executive order restricting immigration from seven countries, which lead to the mistreatment of legal visa holders and permanent residents of the United States in Airports. You probably also understand that there is a huge difference between ruling out new visas from those countries, and dishonoring existing ones. The latter is breaking a promise. Dishonoring agreements like that makes you untrustworthy, and that is very bad for cooperation. Right?

Well, hear this. Continue reading

## Time to spend more than 0.00001% of world GDP on human-level AI alignment

From an outside view, looking in at the Earth, if you noticed that human beings were about to replace themselves as the most intelligent agents on the planet, would you think it unreasonable if 1% of their effort were being spent explicitly reasoning about that transition? How about 0.1%?

Well, currently, world GDP is around \$75 trillion, and in total, our species is spending around \$9MM/year on alignment research in preparation for human-level AI (HLAI). That’s \$5MM on technical research distributed across 24 projects with a median annual budget of \$100k, and 4MM on related efforts, like recruitment and qualitative studies like this blog post, distributed across 20 projects with a median annual budget of \57k. (I computed these numbers by tallying spending from a database I borrowed from Sebastian Farquhar at the Global Priorities Project, which uses a much more liberal definition of “alignment research” than I do.) I predict spending will roughly at least double in the next 1-2 years, and frankly, am underwhelmed… Continue reading ## Considerations against pledging donations for the rest of your life I think donating to charity is great, especially if you make more than \100k per year, placing you well past the threshold where your well-being depends heavily on income (somewhere around \$70k, depending on who does the analysis). I’ve been in that boat before, and donated more than 100% of my disposable income to charity. However, I was also particularly well-positioned to know where money should go at that time, which made donating particularly worth doing. I haven’t made any kind of official pledge to always donate money, because I take pledges/promises very seriously, and for me personally, taking such a pledge seems like a bad idea, even accounting for its signalling value. I’m writing this blog post mainly as a way to reduce social pressure among such folks who earn less than \$100k per year to produce donations, while at the same time encouraging folks who earn more to consider donating more seriously.

Note that I currently work for a charitable institution that I believe is extremely important. So, having been both a benefactor and beneficiary of donations, I hope I may come across as being honest when I say “donating to charity is great.”

Note also that I believe I’m in a somewhat rare situation relative to humans-in-general, but not necessarily a rare situation among folks who are likely to read my blog, who tend to have interests in rationality, effective altruism, existential risk, and other intellectual correlates thereof. Basically, depending on how much information I expect you to actively obtain about the world relative to the size of your donations or other efforts, I may or may not like the idea of you pledging to always donate 10% of your income. Here’s my very rough breakdown of why:

If you either (1) make less than \$100k/year, or (2) might be willing to make less than that at some future time in order to work directly on something the world needs you to do (besides giving), I would not be surprised to find myself recommending against you pledging to always donate 10% of your income every year. Moreover, if you currently spend more than 100 hours per year investigating what the world-at-large needs, I would not be that surprised if in some years you were able to find opportunities to spend \$10k-worth-of-effort (per year on average, rather than every year) that were more effective than giving \$10k/year. Just from eyeballing people I know, I think a person who spends that much time analyzing the world (especially one who is likely to come across this post) can be quite a valuable resource, and I expect high initial marginal returns to their own direct efforts to improve themselves and the world. Example: during my PhD, I spent a considerable fraction of my time on creating a non-profit called the Center for Applied Rationality. I was earning very little money at that time, and donating 10% of it would have been a poor choice. It would have greatly reduced my personal flexibility to spend money on getting things done (saving time by taking taxis, not worrying about the cost of meals when I was in flow working with a group that couldn’t relocate to obtain cheaper food options without breaking productivity, etc.). I think the value of my contribution to CFAR during those years greatly exceeds \$4,000 in charitable donations, which is what 10% of my income over two years would have amounted to. In fact, I would guess that it exceeds \$40,000, so even if I thought things were only 10% likely to turn out as well as they did, not donating in those years was a good idea. In other years when I made much more money, I’ve chosen to donate 100% of my disposable income. You might want to do that sometimes, too, and I would highly recommend considering it, especially if you’re spending a lot of your time investigating where that money should go. But I still might recommend against you pledging to keep donating, unless you expect to stop investigating the world as much as you currently do and will therefore be less likely to discover things in the future that should change your plans for years-at-a-time. ### Sometimes you should trust your own future judgement. You might think that you should just defer all your decisions about where money or effort should go to the investigations of a larger group like GiveWell, OPP, GPP, or GWWC, who spend more time on investigation than you. Such a position favors donating as a way of impacting the world, because your impact gets multiplied by the value of someone else’s investigation. This is a highly tenable position, but I believe it becomes less tenable as the ratio of [value of time you spend investigating cause prioritization] to [value of money or effort you spend on your top cause] increases. E.g., if you’ve spent 100 hours this year identifying and analyzing arguments about what the world needs most, I would not be surprised if you could find a way to spend \$10k worth of money or effort on some important and neglected cause that was more valuable than donating to something with more mainstream support.

On the other hand, it would take more convincing for me to think it was also worth you spending \$1mm worth of money or effort on that cause, since that would represent a larger inefficiency in the charity market that should have been easier for others to have identify, and someone spending$1mm has plenty of incentive to have investigated (or hired investigation) for more than 100 hours. That would be a case where I think it makes more sense to depend on (or even better: pay for your own!) more centralized analysis of what’s needed.

### Expecting variance + respecting your judgement = not pledging

The combined effects of

• expecting variance in whether you should donate, and
• respecting your own judgement for donations valued comparably to the time you spend investigating,
leads me to recommend some folks against pledging to always donate 10% of their income. If you expect low variance and/or low time-ratio-spent-investigating relative to the examples I’ve given, I’m less likely to discourage you from taking such a pledge, because it helps you signal to the world that donating to charity is extremely important.

Having said that: you can donate lots of money without ever pledging do so for the rest of your life, and if you can afford it, I totally think you should do it 🙂

## Voting is like donating thousands of dollars to charity

(Share this post to encourage folks with rational, altruistic leanings to vote more. I originally posted this to LessWrong in 2012, but I figured it was worth re-posting.)

Summary:  It’s often argued that voting is irrational, because the probability of affecting the outcome is so small. But the outcome itself is extremely large when you consider its impact on other people. I estimate that for most people, voting is worth a charitable donation of somewhere between \$100 and \$1.5 million. For me, the value came out to around \$56,000. So I figure something on the order of \$1000 is a reasonable evaluation (after all, I’m writing this post because the number turned out to be large according to this method, so regression to the mean suggests I err on the conservative side), and that’s big enough to make me do it.

Moreover, in swing states the value is much higher, so taking a 10% chance at convincing a friend in a swing state to vote similarly to you is probably worth thousands of expected donation dollars, too. (This is an important move to consider if you’re in a fairly robustly red-or-blue state like New York, California, or Texas where Gelman et al estimate that “the probability of a decisive vote is closer to 1 in a billion.”) I find EV calculations like this for voting or vote-trading to be much more compelling than the typical attempts to justify voting purely in terms of signal value or the resulting sense of pride in fulfilling a civic duty.

### Result

I don’t know which candidate would turn out “better for the world” in my estimation, but I’d consider myself as having at least a 55%*1/(100 million) chance of affecting the outcome in the better-for-the-world direction, and a 45%*1/(100 million) chance of affecting it in the worse-for-the-world direction, so in expectation I’m donating at least around

(55%-45%)*1/(100 million)*(\$100 billion) = \$100

Again, this was pretty conservative:

• Say you’re more like 70% sure,
• Say you’re a randomly chosen american, so your probability of a decisive vote is around 1/10 million;
• Say the outcome matters more on the order of a \$700 billion in charitable donations, given that Obama and Romney’s budgets differ on around \$7 trillion, and say 10% of that is stuff that money is being used as well as moving charitable donations about things you care about.

That makes (70%-30%)*1/(10 million)*(\$700 billion) = \$28,000. Going further, if you’re

• 90% sure,
• voting in Virginia — 1/(3.5 million), and
• care about the whole \$7 trillion dollar difference in budgets, you get (90%-30%)*1/(3.5 million)*(\$7 trillion) = \$1.2 million. This is so large, it becomes a valuable use of time to take 1% chances at convincing other people to vote… which you can hopefully do by sharing this post with them. ### Discussion Now, I’m sure all these values are quite wrong in the sense that taking account everything we know about the current election would give very different answers. If anyone has a more nuanced model of the electoral college than Gelman et al, or a way of helping me better estimate how much the outcome matters to me, please post it! My \$700 billion outcome value still feels a bit out-of-a-hat-ish.

But the intuition to take away here is that a country is a very large operation, much larger than the number of people in it, and that’s what makes voting worth it… if you care about other people. If you don’t care about others, voting is probably not worth it to you. That expected \$100 – \$1,500,000 is going to get spread around to 300 million people… you’re not expecting much of it yourself! That’s a nice conclusion, isn’t it? Nice people should vote, and selfish people shouldn’t?

Of course, politics is the mind killer, and there are debates to be had about whether voting in the current system is immoral because the right thing to do is abstain in silent protest that we aren’t using approval voting, which has better properties than the current system… but I don’t think that’s how to get a new voting system. I think while we’re making whatever efforts we can to build a better global community, it’s no sacrifice to vote in the current system if it’s really worth that much in expected donations.

So if you weren’t going to vote already, give some thought to this expected donation angle, and maybe you’ll start. Maybe you’ll start telling your swing state friends to vote, too. And if you do vote to experience a sense of pride in doing your civic duty, I say go ahead and keep feeling it!

### An image summary

Thanks to Gavan Wilhite and his team for putting together an infographic to summarize these ideas:

I’ve found a few papers by authors with similar thoughts to these:

Also, I found this this interesting Overcoming Bias post, by Andrew Gelman as well.

1 A nitpick, for people like me who are very particular about what they mean by utility: in this post, I’m calculating expected altruistic dollars, not expected utility. However, while our personal utility functions are (or would be, if we managed to have them!) certainly non-linear in the amount of money we spend on ourselves, there is a compelling argument for having the altruistic part of your utility function be approximately linear in altruistic dollars: there are just so many dollars in the world, and it’s reasonable to assume utility is approximately differentiable in commodities. So on the scale of the world, your effect on how altruistic dollars are spent is small enough that you should value them approximately linearly.

2 (Added in response to an email from Ben Hoffman on Oct 28, 2016) This “\$100 billion valuation” step is really two steps combined: a comparison of government cost-effectiveness to the cost-effectiveness of a typical charitable donation, and an estimate of the difference between the two different governments you’d get under different presidents. You could also take into account world-wide externalities here, like the impact of wars. All things considered, I’d be pretty surprised if the difference in candidates over their 4-year term was worth less than an order of magnitude bellow \$100 billion typical-charity dollars.

## Professional feedback form

Since a lot of interest in AI alignment has started to build, I’m getting a lot more emails of the form “Hey, how can I get into this hot new field?”. This is great. In the past I was getting so few messages like this that I could respond to basically all of them with many hours of personal conversation.

But now I can’t respond to everybody anymore, so I have a new plan: leverage academia.

To grossly oversimplify things, here’s the heuristic. If the typical prospective researcher (say, an inbound grad student at a top school) needs 100 hours of guidance/mentorship to become a productive contributor to AI alignment research, maybe only 10 of those hours need to come from someone already in the field, and the remaining 90 hours can come from other researchers in CS/ML/math/econ/neuro/cogsci. So if I have 100 hours of guidance to give this year, I can choose between mentoring 1 person, or 10 people who are getting 90% of their guidance elsewhere. The latter produces more researchers, and potentially researchers of a higher quality because of the diversity of views they’re seeing (provided the student has the filter-out-incorrect-views property, which is of course critical). So that’s what I’m doing, and this blog post is my generic response to questions about how to get into AI alignment research 🙂

I think this policy might also be a good filter for good-team-players, in the following sense: When you’re part of a team, it’s quite helpful if you can leverage resources outside your team to solve the team’s problems without having to draw heavily on the team’s internal resources. Thus, if you want to be part of a new/young field like AI alignment, it’s nice if you can draw on resources outside that field to make it stronger.

## Seeking a paid part-time assistant for AI alignment research

Please share this if you think anyone you know might be interested.

Sometimes in my research I have to do some task on a computer that I could easily outsource, e.g., adding bibliographical data to a list of papers (i.e., when they were written, who the authors were, etc.). If you think you might be interested in trying some work like this, in exchange for

It’s good to be humble, but having low subjective credence in a conclusion is just one way people implement humility; another way is to feel unentitled to form your own belief in the first place, except by copying an “expert authority”. This is especially bad when there essentially are no experts yet — e.g. regarding the nascent sciences of existential risks — and the world really needs people to just start figuring stuff out. Continue reading ## Credence – using subjective probabilities to express belief strengths There are surprisingly many impediments to becoming comfortable making personal use of subjective probabilities, or “credences”: some conceptual, some intuitive, and some social. However, Phillip Tetlock has found that thinking in probabilities is essential to being a Superforcaster, so it is perhaps a skill and tendency worth cultivating on purpose.

Edit: my employer was eventuslly able to order me an e-ink monitor, so the reward is off 🙂

I would like to write LaTeX on a wireless-enabled e-ink display with a 13″ or larger screen to avoid visual fatigue. If you solve this problem for me, I will pay you a \$200 reward, be extremely grateful, and write a blog post explaining your solution so that others might benefit 🙂 Some examples that I would consider solutions: Continue reading

## Seeking a paid personal assistant to create more x-risk research hours

My main bottleneck as a researcher right now is that I have various bureaucracies I need to follow up with on a regular basis, which reduce the number of long interrupted periods I can spend on research. I could really use some help with this. Continue reading

## Use a giant notebook to think better

Having a space to write things down frees up your mind — specifically, your executive system — from the task of holding things in working memory, so you can focus your attention on generating new thoughts instead of looping on your most recent ones to keep them alive. Writing down what’s in your head — math, plans, feelings, whatever — can start paying cognitive dividends in about 5 seconds, and can make the difference between a productive thinking day and a lame one.

## A Mindfulness-Based Stress Reduction course in the East Bay starting January 19

Summary: I think the standardized 8-week MBSR course format is better designed than most introductory meditation practices, and have found David Weinberg in particular to be an excellent mindfulness instructor. Since something like 30 to 100 people have asked me to recommend a way to learn/practice mindfulness, I’m batch-answering with this post. Continue reading

## Red-penning: rolling out an experimental rationality / creativity technique

Note: I’m writing about this technique to (1) reduce the overhead cost of testing it, and (2) illustrate what I consider good practices for “rolling out” a new technique to be added to a rationality curriculum. Despite seeming super-useful in my first-person perspective, experience says the technique itself probably needs to undergo several tests and revisions before it will actually work as intended, even for most readers of my blog I suspect.

## Why scaling slowly has been awesome for CFAR Core

Summary: Since I offered to answer questions about my pledge to donate 10% of my annual salary to CFAR as an existential risk reduction, the question “Why doesn’t CFAR do something that will scale faster than workshops?” keeps coming up, so I’m answering it here. Continue reading

## Break your habits: be more empirical

Summary: The common attitude that “You think too much” might be better parsed as “You don’t experiment enough.” Once you’ve got an established procedure for living optimally in «setting», be a good scientist and keep trying to falsify your theory when it’s not too costly to do so.

## The 2015 x-risk ecosystem

Summary: Because of its plans to increase collaboration and run training/recruiting programs for other groups, CFAR currently looks to me like the most valuable pathway per-dollar-donated for reducing x-risk, followed closely by MIRI, and GPP+80k. As well, MIRI looks like the most valuable place for new researchers (funding permitting; see this post), followed very closely by FHI, and CSER. Continue reading

## Embracing boredom as exploratory overhead cost

(Follow-up to Fun does not preclude burnout)

Sometimes I decide to spend a few weeks or months putting some of my social needs on hold in favor of something specific, like a deadline. But after that’s done, and I “have free time” again, I often find myself leaning toward work as a default pass-time. When I ask my intuition “What’s a fun thing to do this weekend?”, I get a resounding “Work!” Continue reading

## Fun does not preclude burnout

As far as I can tell, I’ve never experienced burnout, but I think that’s only because I notice when I’m getting close. And in recent years, I’ve had a number of friends, especially those interested in Effective Altruism, make the mistake of burning out while having fun. So, I wanted to make a public service announcement: The fact that your work is fun does not mean that you can’t burn out. Continue reading

## Use separate email threads for separate action-requests

When I realized this principle, I experienced around a 2x or 3x increase in my rate of causing-people-to-do-things-over-email, out of the “usually doesn’t work” range into the “usually works” range. I find myself repeating this advice a lot in an attempt to boost the effectiveness of friends interested in effective altruism and related work, so I’m making a blog post to make it easier. Continue reading

## Deliberate Grad School

Among my friends interested in rationality, effective altruism, and existential risk reduction, I often hear: “If you want to have a real positive impact on the world, grad school is a waste of time. It’s better to use deliberate practice to learn whatever you need instead of working within the confines of an institution.” Continue reading

## Willpower Depletion vs Willpower Distraction

I once asked a room full of about 100 neuroscientists whether willpower depletion was a thing, and there was widespread disagreement with the idea. (A propos, this is a great way to quickly gauge consensus in a field.) Basically, for a while some researchers believed that willpower depletion “is” glucose depletion in the prefrontal cortex, but some more recent experiments have failed to replicate this, e.g. by finding that the mere taste of sugar is enough to “replenish” willpower faster than the time it takes blood to move from the mouth to the brain: Continue reading
