My sense is that most historic social reforms also followed path A), e.g. women's suffrage, child labor, civil rights. In the UK, cross-party support was also critical to abolishing slavery, while in the US, where abolition was more politicized, it took a Civil War.

As a non-expert, this is surprising to me. And I'm not sure that this applies to the US context. I think it's useful to distinguish between party polarization (democrats vs republicans) and ideological polarization (liberals vs conservatives). Almost any reform passed in the 1950s-1970s probably had bipartisan support, since the two parties were hardly ideologically polarized at that time. But many of these reforms were absolutely politicized on ideological grounds (liberals typically were in favor of civil rights and environmental reforms. Conservatives were not). I think the anti-slavery movement fits this description as well. Until the last few years before the civil war, the two major political parties (democrats and whigs) both contained large groups of pro-slavery and anti-slavery politicians. So opposition to slavery was bipartisan even though it was clearly polarized on ideological and geographical grounds. Only in the few years before the civil war did the major parties become polarized on the slavery issue.
In recent decades, since the two major parties have become more ideologically polarized, it seems like major reforms were politicized on both party and ideological lines (LGBTQ rights and climate change come to mind).

So, my guess is that most major social reforms in US history were highly politicized on ideological lines, but not necessarily on party lines. I could be wrong though. This is mostly based on reading wikipedia pages.

Finally, I'm struggling to see how and where this is decision relevant for people or organizations - but that's an entirely different set of complaints about how to do analyses.

One way in which it's decision relevant for people considering how much to prioritize extinction risk mitigation. Arguments for extinction risk mitigation being overwhelmingly important often rely on the assumption that the expected value of the future is positive (and astronomically large). A seemingly sensible way to get evidence on whether the future is likely to be good is to look at whether the present is good and whether the trend is positive. I think this is why multiple people have tried to look into those questions (see Holden Karnovsky's blog, which is linked already in the main post, and Chapter 9 of What We Owe the Future). 

In fact, in WWOTF, Macaskill does almost the same exercise as the one in this post, except he uses neuron counts as measures of moral weight instead of rethink priorities' weights. My memory is that he comes to the conclusion that the welfare of animals hardly makes an impact on total welfare. I think this post makes a very nice contribution in showing that Macaskill's conclusion isn't robust to using alternative (and plausible) moral weights.
 

Note: there could be plenty of other arguments for X-risk being overwhelmingly important that don't rely on the claim that the expected value of the future is positive.

On your point about activism on issues other than climate change: When you say "short to medium term", what kind of time scale are you thinking of? I would guess that you mean "the next ten years or so", but I want to make sure. Sometimes around here people use "medium term" to mean the next hundred years.

Hi Sanjay, thanks for the comments.

On fiduciary duty: good to hear your thoughts on this. It looks like I drew the wrong conclusion from the evidence. Would you agree with the following statement instead: 

Fiduciary duty seems to be an obstacle, and could be significantly raising the costs of shareholder activism. That said, it doesn't seem to make the costs prohibitively high. Significant shareholder activism still seems to be possible under current laws and norms, at least on climate change.

That seems right to me given the evidence. I should say that it's not just the New York City Pension Fund who has been active on climate change. They were joined in their activism campaign by CALPERS and CALSTRS, two of the largest public pension funds in the world.

Good question, and I haven't been very clear on this partially because I don't know much about it.

That said, I do think it's common for nonprofits to have lots of money invested in the stock market. This is what philanthropic foundations do. Examples include the Bill and Melinda Gates Foundation ($38B in assets) or the Ford Foundation ($16B). Universities are other examples of nonprofits with huge investments in the stock market (the Harvard Endowment is $53.2B).

Within EA, I think the two major foundations are Good Ventures (which funds Open Philanthropy's recommendations) and FTX Foundation. It looks like Good Ventures had $3.4B in assets in 2020, and it was growing at around $1B a year before then, so it may be significantly higher now (I haven't been able to find more current data). I also haven't been able to find data on FTX since it's so new.

Based on the information provided in the post, I would guess that Good Ventures' existing investments are enough to engage in impactful shareholder activism.

Maybe another commenter with more knowledge about this stuff could chime in and correct any mistakes I'm making.

Thanks for the comment! I tried to address this capital funding concern with the following paragraph in the post:

For reference, a fund of $10B (which I would expect to be around the amount that Open Philanthropy or FTX already have invested) in the S&P 500 would give about a .025% stake in each of those companies. This would be enough to engage in proxy battles but not to use proxy access. However, if you chose to skew your investments toward smaller (and presumably especially influential) companies, then you could potentially acquire much larger percentages of those companies and use more effective engagement strategies.

So the idea is that existing EA investment funds already probably have around a .02% stake in many  large companies like Exxon, which means that they wouldn't have to invest any more money or change their portfolio to follow this strategy.

Thanks! Both the Atkinson article and the Sen interview are very interesting. I would like to see some actual data on the teaching of welfare economics/public economics. People seem to agree that it's declined, but I'm not sure I would agree that it has "disappeared" (anecdotally, I know many people who were exposed to models of optimal redistribution during undergrad. Some of these people were exposed through a required course, and others chose to take a public finance elective). My impression that welfare economics teaching is more common at European universities is also just based on anecdotal evidence. Some actual data would be helpful.

This seems like a very good initiative. It's great to see this cause area moving forward.

Now, like some of the other commenters, I'm having some trouble understanding what kind of work IIDM includes. I agree with the earlier comment which said that the framing of IIDM so far has emphasized improving decision-making a lot more than improving institutions. The original 80k article focused mainly on the possibility of correcting cognitive biases (the kind that people would learn about in cognitive science or psychology classes). There was no mention of the large body of academic work relating to institutional design (this would mainly be learned in political economy or political science courses). Until reading the comments on this post, I was under the impression that IIDM was focused only on "how do we improve decision-making within the current political system" rather than "how can we reform the political system to work better". So, for example, I thought that EA-funded organizations working on voting reform wouldn't fall under IIDM.

If you want IIDM to include institutional reform, then I think that should be made more clear. At least for me, one thing that would have helped is if a different name was used for the overall cause area (like improving institutions) and then within that cause area you have IIDM, which is focused only on improving decision-making within a given institutional structure.

However, I'm pretty unsure of how much overlap there is between these two cause areas, so I'm not sure that it's even worth having the institutional reform people in your working group. Does someone working on constitution design have much to contribute to a discussion on how to teach civil servants to better deal with uncertainty? At least in the academic world, these two fields are fairly separate (from what I can tell). Maybe it would better to have these mostly operate as two separate cause areas.

What is the LTFF's position on whether we're currently at an extremely influential time for direct work? I saw that there was a recent grant on research into patient philanthropy, but most of the grants seem to be made from the perspective of someone who thinks that we are at "the hinge of history". Is that true?
