The cause that you choose to work on is a big factor in how much good you can do. If you choose a cause where itā€™s not possible to help very many people, or where there just arenā€™t any good ways to solve the relevant problems, then you will significantly limit the amount of impact you can have.

Efficient Charity ā€” Do Unto Others

Quote

High overhead costs are only one possible failure mode for a charity. Consider again the Arctic explorer, trying to decide between a $200 parka and a $200 digital camera. Perhaps a parka only cost $100 to make and the manufacturer takes $100 profit, but the camera cost $200 to make and the manufacturer is selling it at cost. This speaks in favor of the moral qualities of the camera manufacturer, but given the choice the explorer should still buy the parka. The camera does something useless very efficiently, the parka does something vital inefficiently. A parka sold at cost would be best, but in its absence the explorer shouldnā€™t hesitate to choose the parka over the camera.
- PageĀ 14

Quote

And likewise, there is only one best charity: the one that helps the most people the greatest amount per dollar. This is vague, and it is up to you to decide whether a charity that raises forty childrenā€™s marks by one letter grade for $100 helps people more or less than one that prevents one fatal case of tuberculosis per $100 or one that saves twenty acres of rainforest per $100. But you cannot abdicate the decision, or you risk ending up like the 11,000 people who accidentally decided that a pretty picture was worth more than a thousand peopleā€™s lives.

If a high-powered lawyer who makes $1,000 an hour chooses to take an hour off to help clean up litter on the beach, heā€™s wasted the opportunity to work overtime that day, make $1,000, donate to a charity that will hire a hundred poor people for $10/hour to clean up litter, and end up with a hundred times more litter removed

Quote

The Roman historian Sallust said of Cato ā€œHe preferred to be good, rather than to seem soā€. The lawyer who quits a high-powered law firm to work at a nonprofit organization certainly seems like a good person. But if we define ā€œgoodā€ as helping people, then the lawyer who stays at his law firm but donates the profit to charity is taking Catoā€™s path of maximizing how much good he does, rather than how good he looks.

Effective altruism as mining for gold

Prospecting for Gold

Quote

When you see gold, take a moment to think about what you value. Many people wonā€™t just value one particular thing. However, do think about what you care about and put that in place of the gold.
- PageĀ 17
-
- [note::This seems like a useful exercise in terms of figuring out what top-level goals one should strive for.]

Quote

Elsewhere in this conference, there are going to be treasure maps and discussions of where the gold is. Iā€™m not going to do that in this talk. Iā€™m instead going to be focusing on the tools and techniques that we can use for locating gold, rather than trying to give my view of where it is directly.

- [note::I like this framing - EA is really all about finding out what and where the gold is ("gold" being what we altruistically value)]

Gold is unevenly spread

Techniques for finding gold

Heavy-tailed distributions

Quote

So, on the left of the distribution that is not heavy-tailed, I can see that the gold is fairly evenly spread across a lot of different places. If we want to just get most of the gold, what is important is getting to as many different places as possible. Solar power is like this. Sure, some places get more sunlight than other places, but the amount of solar power you generate depends more on how many total solar panels you have, than on exactly where you place them. Over on the right, though, we have a distribution where you can see a lot of the area that spikes on the right-hand side. This just means that a lot of the gold, and if this is an actual stand-in for something that we value, a lot of what is valuable comes in this extreme of the distribution of things, which are just unusually good.

Quote

So just because somebody says, ā€œHey, this is gold,ā€ doesnā€™t mean we should always take peopleā€™s word for it.
- PageĀ 24
-

Quote

A nice property of literal gold is that when you dig it up, youā€™re pretty sure that you can recognise ā€œyes I have goldā€. We often have to deal with cases where we donā€™t have this. We donā€™t have the gold, so we have to carefully try to infer its existence, by using different tools. This fact is like the dark matter of value.
- PageĀ 24

- [note::"Altruistic value is like dark matter - we have to infer it's existence by using different tools"]

Recognising gold

Quote

You can still get gold, but itā€™s more work for each little bit, for each nugget that youā€™re getting out. This is the general phenomenon of ā€˜diminishing returnsā€™ on work that youā€™re putting in. This concept comes up in a lot of different places, and so it is worth having an understanding of it.

Quote

The first of these dimensions is scale. All else being equal, we would prefer to go somewhere where there is a lot of gold, rather than a little bit of gold.

Scale

Quote

Second: tractability. Weā€™d like to go somewhere where we make more progress per unit work. Somewhere, where itā€™s nice and easy to dig the ground, rather than trying to get your gold out of a swamp.

Quote

And third is uncrowdedness. This has sometimes been called neglectedness. I think that term is a bit confusing. Itā€™s a bit ambiguous because sometimes people use ā€˜neglectednessā€™ to mean that this is an area which we should allocate more resources to. What I mean here is that there arenā€™t many people looking at it. All else being equal, we would rather go to an area where people havenā€™t already picked up the nuggets of gold on the ground, than one where they have. And now the only gold remaining is quite hard to extract.
- PageĀ 27

- [note::Nuanced yet important distinction between "neglectedness'" and "uncrowdedness]

Uncrowdedness

Tractability

Quote

The first term is measuring the amount of value you get for, say, solving an extra one percent of a solution.
- PageĀ 28
-

Quote

It is an elasticity here, which is a technical term. Itā€™s a pretty useful and general term (go look it up on Wikipedia, if youā€™re interested). Here, it is measuring, for a proportional increase in the amount of work thatā€™s being done, what proportion of a solution that gives you.
- PageĀ 28
-
- [note::#research-this]

Quote

The final term just cancels to one over the total amount of work being done. So that is very naturally a measure of uncrowdedness.

Scale, Tractability, Uncrowdedness

Quote

Iā€™m not going to spend an hour helping a bee, even if nobody else is helping it and it would be pretty easy to help, because just the scale of it is pretty small. I donā€™t think we should work on perpetual motion machines, even though basically nobody is working on it and it would be really fantastic if we succeeded. Because it seems like itā€™s not tractable. And this [...] might give us a warning against actually working on climate change. Because at a global scale, that gets a lot of attention, as a problem.

Absolute and marginal priority
Quote

If we are having a conversation about what we as individuals or as small groups should do, I think itā€™s appropriate to use this notion of marginal priority, of how much do extra resources help. If weā€™re talking about what we collectively as a society or the world should do, I think itā€™s often correct to talk about this kind of notion of absolute priority and how much resources ought to be invested in it, total.

Quote

And maybe we have some technologies which are destructive. So we can use dynamite and dynamite gets us loads of gold now, but it also blows up some gold, and now we never get that gold later. That could be pretty good if you are focusing just on trying to get gold in the short term. But it could be bad from this eventual gold perspective.
- PageĀ 31
-

Long-term gold

Quote

And so one of the major drivers of how much gold is eventually extracted is the order in which the technologies are developed, and the sequencing. If we discover the dynamite first, people are going to go and have fun with their dynamite and theyā€™re going to destroy a lot of the gold. If we discover the drill first, then by the time dynamite comes along, people will go ā€œWell, why would we use that? We have this fantastic drill.ā€

Comparative advantage

Working together

Quote

I have Harry, Hermione and Ron, and they have three tasks that they need to do to get some gold. They need to do some research, they need to mix some potions, and they need to do some wand work. Hermione is the best at everything, but she doesnā€™t have a time turner, so she canā€™t do everything. So we need to have some way of distributing the work. This is the idea of comparative advantage. Hermione has an absolute advantage on all of these tasks, but it would be a waste for her to go and work on the potions because Harry is not so bad at potions. And really, nobody else is at all good at doing the research in the library. So we should probably put her on this.
- PageĀ 33
- coordination, comparative advantage,

Quote

This is a bit more speculative, but I think we can also apply this at the time level. We can ask ourselves, ā€œWhat are we, today, the people of 2016, particularly well suited to do, versus people in the past and people in the future?ā€ We canā€™t change what people in the past did. But we can make a comparison of what our comparative advantage is relative to people in the future. And if there is a challenge, if there were going to be some different possible challenges in the future that we need to meet, it makes sense that we should be working on the early ones. Because if challenges are coming in 2020, the people in 2025 just do not have a chance to work on that.

So, maybe it is the case that we can adapt one of these existing institutions for our purpose, which is trying to aggregate knowledge about what are the ways to go and do the most good. But maybe we want something a bit different, and maybe somebody in this room is going to do some work on coming up with valuable institutions for this. I actually think this is a really important problem. And itā€™s one that is going to become more important for us to deal with as a community, as the community grows.

Do you believe it because somebody else told you? Do you believe it because you have really thought this through carefully and worked it out for yourself? There is a blur between those. Often somebody tells you, and they give you some reasons. And you are thinking: ā€œOh, those reasons kind of check out,ā€ but you havenā€™t deeply examined the argument yourself.

Iā€™m shortening the chain of Chinese whispers, of passing this message along. And as things get passed along, itā€™s possible that mistakes enter or just something isnā€™t well grounded, and then it gets repeated. By going back and checking earlier sources in the chain, we can try to reduce that, and try to make ourselves more robustly confident in these statements.

Ways to make money, maybe they actually start out distributed across a wide range. This is a log scale now, and it is meant to represent one of those heavy-tailed distributions, but then people who are losing money, say, ā€œWell, this sucks,ā€ and they stopped doing that thing. And they see other people who are doing activities which are making lots of money. And they think: ā€œYeah, Iā€™m going to go do that.ā€ And then you get more people going into that area, and then diminishing returns mean that you actually make less money than you used to, by doing stuff in that area.

Quote

a crucial consideration is a consideration such that if it were taken into account it would overturn the conclusions we would otherwise reach about how we should direct our efforts, or an idea or argument that might possibly reveal the need not just for some minor course adjustment in our practical endeavors but a major change of direction or priority.

Whereas with utilitarianism, the utilitarian preference extends far and wide beyond our familiar environment, including into the cosmic commons and billions of years into the future and super advanced civilizations: what they do matters from the utilitarian perspective, and matters a lot. Most of what the utilitarian preference cares about is stuff that we have no familiarity with.
- PageĀ 49

if one tries to think about how to apply utilitarianism to a world that has a finite probability of being infinite, one will run into difficulties in terms of how to measure different infinite magnitudes and still seeing how we could possibly make any difference to it.

The third possible reason here is that one might think that we are kind of close, not super close, but close to some pivot point in history.

Crucial considerations and utilitarianism

Quote

This could affect the personal domain as well. Itā€™s just like with an ordinary personā€™s typical utility function: they probably donā€™t place a million times more value on living for a billion years than living for a hundred years, or a thousand times more value on raising a thousand children than on raising one child. So even though the future still exists, it just doesnā€™t weigh as heavily in a normal human utility function as it does for utilitarians.

If we plot capacity, which could be level of economic development and technological sophistication, stuff like that, on one axis and time on the other, my view is that the human condition is a kind of metastable region on this capability axis.

The point here is that to have the best possible condition; we need super advanced technology: to be able to access the cosmic commons, to be able to cure all the diseases that plague us, etc. I think to have the best possible world, youā€™ll also need a huge amount of insight and wisdom, and a large amount of coordination so as to avoid using high technology to wage war against one another, and so forth.

However, we might feel itā€™s very difficult to get strong reasons for knowing whether more people in this room is better, or whether there is some inverse relationship.

Possible areas with additional crucial considerations

Quote

Take into account that expected value changes are probably smaller than they appear. If you are a utilitarian, letā€™s say you think of this new argument that has this radical implication for what you should be doing, the first instinct might be to radically change your expected utility of different practical policies in light of this new insight. But maybe when you reflect on the fact that there are new crucial considerations being discovered every once in awhile, maybe you should still change List of some areas with candidate remaining CCs or CCCs ā€¢ Counterfactual trade ā€¢ Simulation Stuff ā€¢ Infinite paralysis ā€¢ Pascalian muggings ā€¢ Different kinds of aggregative ethics (total, average, negative) ā€¢ Information hazards ā€¢ Aliens ā€¢ Baby universes ā€¢ Other kinds of moral uncertainty ā€¢ Other game theory stuff ` ā€¢ Pessimistic metainduction; epistemic humility; anthropics ā€¢ Insects, subroutine

very many of them. So that maybe the effect of our policies on insect well-being mind trump the effect of our policies on human well-being or animals in factories and stuff like that. Iā€™m not saying it does, but itā€™s a question that is non-obvious and that could have a big impact.

The Moral Value of Information

Take this third case. You start to test the untested coin, so you perform a series of flips with the coin, and you start to see a pattern [Figure 3]. In a case like this, it looks like the coin in front of you is pretty heavily heads biased, or you at least start to quite rapidly increase your credence that itā€™s heads biased. So, your credence that itā€™s going to come up heads next time is much higher. Because you had less evidence before, this credence was much more fragile, so now youā€™ve seen a change. This would not happen if you got this sequence on the well-tested coin, because more evidence means that your credences are more resilient. If you saw a series of five head after performing a million trials, and it lands heads roughly half the time, this is just not going to make a huge difference to what you expect the next coin flip to be.

So, when is exploring especially cost effective? Essentially, when there are three features. When thereā€™s more uncertainty about the direct value of an intervention, so this means options that have high expected value, but low resilience. When there are high benefits of certainty about the direct value, so when we can basically repeatedly mine something for value. And when there are low information costs, so when informationā€™s not too costly to obtain and the delay is low cost

Efficient Charity ā€” Do Unto Others

Quote

High overhead costs are only one possible failure mode for a charity. Consider again the Arctic explorer, trying to decide between a $200 parka and a $200 digital camera. Perhaps a parka only cost $100 to make and the manufacturer takes $100 profit, but the camera cost $200 to make and the manufacturer is selling it at cost. This speaks in favor of the moral qualities of the camera manufacturer, but given the choice the explorer should still buy the parka. The camera does something useless very efficiently, the parka does something vital inefficiently. A parka sold at cost would be best, but in its absence the explorer shouldnā€™t hesitate to choose the parka over the camera.

And likewise, there is only one best charity: the one that helps the most people the greatest amount per dollar. This is vague, and it is up to you to decide whether a charity that raises forty childrenā€™s marks by one letter grade for $100 helps people more or less than one that prevents one fatal case of tuberculosis per $100 or one that saves twenty acres of rainforest per $100. But you cannot abdicate the decision, or you risk ending up like the 11,000 people who accidentally decided that a pretty picture was worth more than a thousand peopleā€™s lives.

The lawyer who quits a high-powered law firm to work at a nonprofit organization certainly seems like a good person.

Gold is unevenly spread

Techniques for finding gold

Heavy-tailed distributions

Quote

So, on the left of the distribution that is not heavy-tailed, I can see that the gold is fairly evenly spread across a lot of different places. If we want to just get most of the gold, what is important is getting to as many different places as possible. Solar power is like this. Sure, some places get more sunlight than other places, but the amount of solar power you generate depends more on how many total solar panels you have, than on exactly where you place them. Over on the right, though, we have a distribution where you can see a lot of the area that spikes on the right-hand side. This just means that a lot of the gold, and if this is an actual stand-in for something that we value, a lot of what is valuable comes in this extreme of the distribution of things, which are just unusually good.

A nice property of literal gold is that when you dig it up, youā€™re pretty sure that you can recognise ā€œyes I have goldā€. We often have to deal with cases where we donā€™t have this. We donā€™t have the gold, so we have to carefully try to infer its existence, by using different tools. This fact is like the dark matter of value.

You can still get gold, but itā€™s more work for each little bit, for each nugget that youā€™re getting out.

And third is uncrowdedness. This has sometimes been called neglectedness. I think that term is a bit confusing. Itā€™s a bit ambiguous because sometimes people use ā€˜neglectednessā€™ to mean that this is an area which we should allocate more resources to. What I mean here is that there arenā€™t many people looking at it. All else being equal, we would rather go to an area where people havenā€™t already picked up the nuggets of gold on the ground, than one where they have. And now the only gold remaining is quite hard to extract.

It is an elasticity here, which is a technical term. Itā€™s a pretty useful and general term (go look it up on Wikipedia, if youā€™re interested). Here, it is measuring, for a proportional increase in the amount of work thatā€™s being done, what proportion of a solution that gives you.

Absolute and marginal priority
Quote

If we are having a conversation about what we as individuals or as small groups should do, I think itā€™s appropriate to use this notion of marginal priority, of how much do extra resources help. If weā€™re talking about what we collectively as a society or the world should do, I think itā€™s often correct to talk about this kind of notion of absolute priority and how much resources ought to be invested in it, total.

And maybe we have some technologies which are destructive. So we can use dynamite and dynamite gets us loads of gold now, but it also blows up some gold, and now we never get that gold later.

And so one of the major drivers of how much gold is eventually extracted is the order in which the technologies are developed, and the sequencing.

If we discover the drill first, then by the time dynamite comes along, people will go ā€œWell, why would we use that? We have this fantastic drill.ā€

Working together

Quote

I have Harry, Hermione and Ron, and they have three tasks that they need to do to get some gold. They need to do some research, they need to mix some potions, and they need to do some wand work. Hermione is the best at everything, but she doesnā€™t have a time turner, so she canā€™t do everything. So we need to have some way of distributing the work. This is the idea of comparative advantage. Hermione has an absolute advantage on all of these tasks, but it would be a waste for her to go and work on the potions because Harry is not so bad at potions. And really, nobody else is at all good at doing the research in the library. So we should probably put her on this.

This is a bit more speculative, but I think we can also apply this at the time level. We can ask ourselves, ā€œWhat are we, today, the people of 2016, particularly well suited to do, versus people in the past and people in the future?ā€ We canā€™t change what people in the past did. But we can make a comparison of what our comparative advantage is relative to people in the future. And if there is a challenge, if there were going to be some different possible challenges in the future that we need to meet, it makes sense that we should be working on the early ones. Because if challenges are coming in 2020, the people in 2025 just do not have a chance to work on that.

And they see other people who are doing activities which are making lots of money.

Whereas with utilitarianism, the utilitarian preference extends far and wide beyond our familiar environment, including into the cosmic commons and billions of years into the future and super advanced civilizations: what they do matters from the utilitarian perspective, and matters a lot.

This could affect the personal domain as well.

Take this third case. You start to test the untested coin, so you perform a series of flips with the coin, and you start to see a pattern [Figure 3]. In a case like this, it looks like the coin in front of you is pretty heavily heads biased, or you at least start to quite rapidly increase your credence that itā€™s heads biased. So, your credence that itā€™s going to come up heads next time is much higher. Because you had less evidence before, this credence was much more fragile, so now youā€™ve seen a change. This would not happen if you got this sequence on the well-tested coin, because more evidence means that your credences are more resilient. If you saw a series of five head after performing a million trials, and it lands heads roughly half the time, this is just not going to make a huge difference to what you expect the next coin flip to be.
