Taking Effective Altruism Seriously

The noblest charity is to prevent a man from accepting charity, and the best alms are to show and enable a man to dispense with alms.

Moses Maimonides.

Background

Effective Altruism (EA) is "a philosophy and social movement that applies evidence and reason to determine the most effective ways to improve the world." Along with the related organisation GiveWell, it often focuses on getting the most "bang for your buck" in charitable donations. Unfortunately, despite their stated aims, their actual charitable recommendations are generally wasteful, such as cash transfers to poor Africans. This leads to the obvious question - how can we do better?

Doing better

One of the positive aspects of EA theory is its attempt to widen the scope of altruism beyond the traditional. For instance, to take into account catastrophic risks, and the far future. However, altruism often produces a far-mode bias where intentions matter above results. This can be a particular problem for EA - for example, it is very hard to get evidence about how we are affecting the far future. An effective method needs to rely on a tight feedback loop between action and results, so that continual updates are possible. At the extreme, Far Mode operates in a manner where no updating on results takes place at all. However, it is also important that those results are of significant magnitude as to justify the effort. EA has mostly fallen into the latter trap - achieving measurable results, but which are of no greater consequence.

The population of sub-Saharan Africa is around 950 million people, and growing. They have been a prime target of aid for generations, but it remains the poorest region of the world. Providing cash transfers to them mostly merely raises consumption, rather than substantially raising productivity. A truly altruistic program would enable the people in these countries to generate their own wealth so that they no longer needed poverty - unconditional transfers, by contrast, is an idea so lazy even Bob Geldof could stumble on it. The only novel thing about the GiveWell program is that the transfers are in cash.

Unfortunately, no-one knows how to turn poor African countries into productive Western ones, short of colonization. The problem is emphatically not a shortage of capital, but rather low productivity, and the absence of effective institutions in which that capital can be deployed. Sadly, these conditions and institutions cannot simply be transplanted into those countries.

A greater charity

However, there do exist countries with high productivity, and effective institutions in which that capital can be deployed. That capital then raises world productivity. As F.A. Harper wrote:

Savings invested in privately owned economic tools of production amount to... the greatest economic charity of all.

That is because those tools increase the productivity of labour, and so raise output. The pie has grown. Moreover, the person who invests their portion of the pie into new capital is particularly altruistic, both because they are not taking a share themselves, and because they are making a particularly large contribution to future pies.

In the same way that using steel to build tanks means (on the margin) fewer cars and vice-versa, using craftsmen to build a new home means (on the margin) fewer factories and vice-versa. Investment in capital is foregone consumption. Moreover, you do not need to personally build those economic tools; rather, you can part-finance a range of those tools by investing in the stock market, or other financial mechanisms.

Now, it's true that little of that capital will be deployed in sub-Saharan Africa at present, due to the institutional problems already mentioned. Investing in these countries will likely lead to your capital being stolen or becoming unproductive - the same trap that prevents locals from advancing equally prevents foreign investors from doing so. However, if sub-Saharan Africa ever does fix its culture and institutions, then the availability of that capital will then serve to rapidly raise productivity and then living standards, much as is taking place in China. Moreover, by making the rest of the world richer, this increases the level of aid other countries could provide to sub-Saharan Africa in future, should this ever be judged desirable. It also serves to improve the emigration prospects of individuals within these countries.

Feedback

Another great benefit of capital investment is the sharp feedback mechanism. The market economy in general, and financial markets in particular, serve to redistribute capital from ineffective to effective ventures, and from ineffective to effective investors. As a result, it is no longer necessary to make direct (and expensive) measurements of standards of living in sub-Saharan Africa; as long as your investment fund is gaining in value, you can rest safe in the knowledge that its growth is contributing, in a small way, to future prosperity.

Commitment mechanisms

However, if investment in capital is foregone consumption, then consumption is foregone investment. If I invest in the stock market today (altruistic), then in ten years' time spend my profits on a bigger house (selfish), then some of the good is undone. So the true altruist will not merely create capital, he will make sure that capital will never get spent down. One good way of doing that would be to donate to an institution likely to hold onto its capital in perpetuity, and likely to grow that capital over time. Perhaps the best example of such an institution would be a richly-endowed private university, such as Harvard, which has existed for almost 400 years and is said to have an endowment of $32 billion.

John Paulson recently gave Harvard $400 million. Unfortunately, this meant he came in for a torrent of criticism from people claiming he should have given the money to poor Africans, etc. I hope to see Effective Altruists defending him, as he has clearly followed through on their concepts in the finest way.

Further thoughts and alternatives

 

  • Some people say that we are currently going through a "savings glut" in which capital is less productive than previously thought. In this case, it may be that Effective Altruists should focus on funding (and becoming!) successful entrepreneurs in different spaces.
  • I am sympathetic to the Thielian critique that innovation is being steadily stifled by hostile forces. I view the past 50 years, and the foreseeable future, as a race between technology and regulation, which technology is by no means certain to win. It may be that Effective Altruists should focus on political activity, to defend and expand economic liberty where it exists - this is currently the focus of my altruism.
  • However, government is not the enemy; rather, the enemy is the cultural beliefs and conditions that create a demand for the destruction of economic liberty. To the extent this critique, it may be that Effective Altruists should focus on promoting a pro-innovation and pro-liberty mindset; for example, through movies and novels.

Conclusion


Effective altruists should be applauded for trying to bring evidence and reason to a subject that is plagued by far-mode thinking. But taking their ideas seriously quickly leads to a much more radical approach.

 

The File Drawer Effect and Conformity Bias (Election Edition)

31 Salemicus 08 May 2015 04:51PM

As many of you may be aware, the UK general election took place yesterday, resulting in a surprising victory for the Conservative Party. The pre-election opinion polls predicted that the Conservatives and Labour would be roughly equal in terms of votes cast, with perhaps a small Conservative advantage leading to a hung parliament; instead the Conservatives got 36.9% of the vote to Labour's 30.4%, and won the election outright.

There has already been a lot of discussion about why the polls were wrong, from methodological problems to incorrect adjustments. But perhaps more interesting is the possibility that the polls were right! For example, Survation did a poll on the evening before the election, which predicted the correct result (Conservatives 37%, Labour 31%). However, that poll was never published because the results seemed "out of line." Survation didn't want to look silly by breaking with the herd, so they just kept quiet about their results. Naturally this makes me wonder about the existence of other unpublished polls with similar readings.

This seems to be a case of two well know problems colliding with devastating effect. Conformity bias caused Survation to ignore the data and go with what they "knew" to be the case (for which they have now paid dearly). And then the file drawer effect meant that the generally available data was skewed, misleading third parties. The scientific thing to do is to publish all data, including "outliers," both so that information can change over time rather than be anchored, and to avoid artificially compressing the variance. Interestingly, the exit poll, which had a methodology agreed beforehand and was previously committed to be published, was basically right.

This is now the third time in living memory that opinion polls have been embarrassingly wrong about the UK general election. Each time this has lead to big changes in the polling industry. I would suggest that one important scientific improvement is for polling companies to announce the methodology of a poll and any adjustments to be made before the poll takes place, and commit to publishing all polls they carry out. Once this became the norm, data from any polling company that didn't follow this practice would be rightly seen as unreliable by comparison.

[LINK] Steven Hawking warns of the dangers of AI

10 Salemicus 02 December 2014 03:22PM

From the BBC:

[Hawking] told the BBC:"The development of full artificial intelligence could spell the end of the human race."

...

"It would take off on its own, and re-design itself at an ever increasing rate," he said. "Humans, who are limited by slow biological evolution, couldn't compete, and would be superseded."

There is, however, no mention of Friendly AI or similar principles.

In my opinion, this is particularly notable for the coverage this story is getting within the mainstream media. At the current time, this is the most-read and most-shared news story on the BBC website.

[LINK] Joseph Bottum on Politics as the Mindkiller

2 Salemicus 27 February 2014 07:40PM

One of my favourite Less Wrong articles is Politics is the mindkiller. Part of the reason that political discussion so bad is the poor incentives - if you have little chance to change the outcome, then there is little reason to strive for truth or accuracy - but a large part of the reason is our pre-political attitudes and dispositions. I don't mean to suggest that there is a neat divide; clearly, there is a reflexive relation between the incentives within political discussion and our view of the appropriate purpose and scope of politics. Nevertheless, I think it's a useful distinction to make, and so I applaud the fact that Eliezer doesn't start his essays on the subject by talking about incentives, feedback or rational irrationality - instead he starts with the fact that our approach to politics is instinctively tribal.

This brings me to Joseph Bottum's excellent recent article in The American, The Post-Protestant Ethic and Spirit of America. This charts what he sees as the tribal changes within America that have shaped current attitudes to politics. I think it's best seen in conjunction with Arnold Kling's excellent The Three Languages of Politics; while Kling talks about the political language and rhetoric of modern American political groupings, Bottum's essay is more about the social changes that have led to these kinds of language and rhetoric.

We live in what can only be called a spiritual age, swayed by its metaphysical fears and hungers, when we imagine that our ordinary political opponents are not merely mistaken, but actually evil. When we assume that past ages, and the people who lived in them, are defined by the systematic crimes of history. When we suppose that some vast ethical miasma, racism, radicalism, cultural self-hatred, selfish blindness, determines the beliefs of classes other than our own. When we can make no rhetorical distinction between absolute wickedness and the people with whom we disagree. The Republican Congress is the Taliban. President Obama is a Communist. Wisconsin’s governor is a Nazi.

...

The real question, of course, is how and why this happened. How and why politics became a mode of spiritual redemption for nearly everyone in America, but especially for the college-educated upper-middle class, who are probably best understood not as the elite, but as the elect, people who know themselves as good, as relieved of their spiritual anxieties by their attitudes toward social problems.

[LINK] - Aaron Sell (Psychology Today) on the Politicisation of Science

5 Salemicus 28 August 2013 08:25PM

Dr. Aaron Sell recently wrote an interesting piece about political incentives and shoddy statistical work in science. In particular, he was highly critical of the much-publicized Conley article in the Journal of Personality and Social Psychology which attempted to demonstrate that "large gender differences... [in willingness to engage in] casual sex [have] more to do with perceived personality characteristics of the female versus male proposers than with gender differences."

[[The full article can be found here. Please note - I have deliberately chosen to omit quoting any material which Less Wrongers may find mindkilling. It would be nice if we could keep it that way.]]

He points out that Conley's results were obtained by hypothetical pseudo-experiments, and spurious controls. For example, when Conley found that men were more willing to sleep with their friends than women, she made this difference "evaporate" by:

control[ling] for “sexual capabilities.” The sexual capabilities covariate contained two items: “the proposer would be a great lover” and “would provide you with a positive sexual experience.” Keep in mind, these items were rated by the subjects just after deciding how likely they would be to have a sexual encounter with the person! If you control for two tightly correlated variables any effect disappears. The gap in male and female pay completely disappears when you control for testicle number... So how tightly correlated is “likelihood of agreeing to sex” with “would provide a positive sexual experience”? We don’t know; it’s not reported. JPSP. Seriously.

Yet for bottom line reasons, we now find Eagly and Woods reading Conley uncritically, and even claiming that she has overturned Clark and Hatfield's classic (and truly experimentally based) article demonstrating that women are radically less willing than men to have casual sex.

Sell concludes:

This sort of nonsense is an indictment of our science... As long as the most prestigious journals of our discipline publish this kind of political masturbation , we have no right to demand that the public take us seriously. When politics and good science collide there is no reason the public should bet on science. They are better off trusting their uninformed intuitions. An imbecile... know[s] damn well that 80% of women don’t want casual sex with random men who are “reputed to be sexually skilled.”

While empiricism is great, I have long believed that the social and organisational structures in which science is practised makes it especially vulnerable to political capture, so this plays right into my biases. Am I missing something important?

[LINK] Cochrane on Existential Risk

0 Salemicus 20 August 2013 10:42PM

The finance professor John Cochrane recently posted an interesting blog post. The piece is about existential risk in the context of global warming, but it is really a discussion of existential risk generally; many of his points are highly relevant to AI risk.

If we [respond strongly to all low-probability threats], we spend 10 times GDP.

It's a interesting case of framing bias. If you worry only about climate, it seems sensible to pay a pretty stiff price to avoid a small uncertain catastrophe. But if you worry about small uncertain catastrophes, you spend all you have and more, and it's not clear that climate is the highest on the list...

All in all, I'm not convinced our political system is ready to do a very good job of prioritizing outsize expenditures on small ambiguous-probability events.

He also points out that the threat from global warming has a negative beta - i.e. higher future growth rates are likely to be associated with greater risk of global warming, but also the richer our descendants will be. This means both that they will be more able to cope with the threat, and that the damage is less important from a utilitarian point of view. Attempting to stop global warming therefore has positive beta, and therefore requires higher rates of return than simple time-discounting.

It strikes me that this argument applies equally to AI risk, as fruitful artificial intelligence research is likely to be associated with higher economic growth. Moreover:

The economic case for cutting carbon emissions now is that by paying a bit now, we will make our descendants better off in 100 years.

Once stated this way, carbon taxes are just an investment. But is investing in carbon reduction the most profitable way to transfer wealth to our descendants? Instead of spending say $1 trillion in carbon abatement costs, why don't we invest $1 trillion in stocks? If the 100 year rate of return on stocks is higher than the 100 year rate of return on carbon abatement -- likely -- they come out better off. With a gazillion dollars or so, they can rebuild Manhattan on higher ground. They can afford whatever carbon capture or geoengineering technology crops up to clean up our messes.

So should we close down MIRI and invest the funds in an index tracker?

[LINK] Relational models of Exchange

3 Salemicus 17 May 2012 07:19PM

The title may make it seem like it's mind-killing stuff (politics, religion, etc) but in fact it's about the different way people relate to one another. A lot of the things discussed in the article get mentioned here as "cognitive biases" but in fact they are a fundamental part of how people interact. 

http://www.theatlantic.com/business/archive/2012/05/mitt-romney-one-night-stands-and-the-economics-of-relationships/257239/

For me, the highlight is when he talks about people approaching the same exchange with different relational models.
