Bio

I am the Principal Research Director at Rethink Priorities. I lead our Surveys and Data Analysis department and our Worldview Investigation Team. 

The Worldview Investigation Team previously completed the Moral Weight Project and CURVE Sequence / Cross-Cause Model. We're currently working on tools to help EAs decide how they should allocate resources within portfolios of different causes, and to how to use a moral parliament approach to allocate resources given metanormative uncertainty.

The Surveys and Data Analysis Team primarily works on private commissions for core EA movement and longtermist orgs, where we provide:

  • Private polling to assess public attitudes
  • Message testing / framing experiments, testing online ads
  • Expert surveys
  • Private data analyses and survey / analysis consultation
  • Impact assessments of orgs/programs

Formerly, I also managed our Wild Animal Welfare department and I've previously worked for Charity Science, and been a trustee at Charity Entrepreneurship and EA London.

My academic interests are in moral psychology and methodology at the intersection of psychology and philosophy.

For reference, about 10% of EAs in the last EA Survey reported their career plan as working in government or policy. That's not very far behind the top categories, and it doesn't account for the 14% of respondents still deciding.

It seems David's comment below is particularly relevant here, and that it might be useful to have a two-way table of uptake rates? With University/General population on one axis and Passive/Active on the other. (Let me know if this exists and I'm missing it, otherwise if you agree this might be useful I can try and use any relevant surveys to estimate this)

 

Thanks Arthur! Unfortunately, I'm not sure that this data exists. It seems that we'd need to know both how many EA members there are at different universities and where they first heard of EA (perhaps CEA could gather this in future groups surveys).

We do have data about where people on campus in general had heard of EA.[1] Interestingly, ~0 of the people in our sample who seemed to have encountered EA (~220 people) seemed to be EAs themselves, which is itself somewhat suggestive of conversion rates. 

As we can see, people on campus are more likely to say they heard of EA due to an EA group (14%), or a club fair (7%), that is probably likewise attributable to direct group activity. Some of the people who simply heard about EA around campus or from friends may also be attributable to group activity, but not have been directly outreached to. Many people clearly encountered EA only through more indirect means though, e.g. wider media, school or classes.[2]

    This excludes responses which did not give an interpretable answer as to where they had heard of EA.

    Though it is worth bearing in mind that what we count as direct/indirect or higher/lower quality outreach is somewhat theoretically laden (and these dimensions can come apart). I recall, many years ago, it was more common to believe that people reading books would be 'high fidelity', and that groups might be 'lower fidelity'; now a minority view.

Agreed with Jamie's points above.

A couple of additional points:

  • We have estimates of the numbers of people who have heard of EA on specific campuses from 2022 (from the study referenced here).
    • These suggest that the percentages who have encountered EA at elite universities are considerably higher.
    • Even so, many of the people who've encountered EA, clearly barely know what it is (they've heard about it from someone else on campus or some such). As such, they definitely shouldn't be considered as people who've been outreached to and failed to engage. Very few people have ever encountered EA outreach and the probability of engaging, conditional on encountering outreach, may be much higher.

  • We have data comparing where people have heard of effective altruism for the general population and for the EA population (from 2020-2021).
    • This suggests people actually in EA are much more likely to have encountered EA through a personal contact or 80,000 Hours, an EA Group etc., whereas people who have heard about EA in the general population are much more likely to have encountered it through the media or in the course of their education.
    • It seems very plausible to me that merely reading about EA in the news, or hearing about it one's classroom, is much less likely to lead to someone joining EA than if they encounter actual outreach encouraging them to join EA and presenting them a way in (though this likely also reflects differences between the groups encountering EA or not). We've observed before that in-person routes into EA (personal contacts and EA Groups) seem particularly important for some demographics groups.[1]

We'd be happy to repeat either of these surveys if people are interested.

    The results are directionally similar if you exclude those who "Don't remember", which is much more common for the general population.

Thanks Ben!

I think we should be able to do this[1] and I agree it seems interesting. It looks like Google has quite high favourability and Bill Gates personally (I did not see recent numbers for the Gates Foundation), reasonably high, but lower.

    Though there is some complication around whether we're looking at the sentiment of (i) people who've been assessed as truly being aware (most comparable to our attitudes among those who have already heard question, but would need an additional test for those respondents), (ii) people who've not claimed awareness (most comparable to our attitudes among those who have not heard question but less relevant).

Nice idea! 

I tried this in a recent conversation of mine and it opted to write about data analysis instead. It's interesting, but not surprising, that what it was interested in writing about varied so much based on the preceding conversation.


Your data reveals something fascinating: "find the most effective ways" outperforms "ways to maximize your impact" by about 0.35 points, despite both essentially describing optimization. This gap hints at something deeper about how we process language and ideas.

I think "most effective" works better because it's inherently comparative and concrete. It implies there's a landscape of options that can be ranked, studied, and chosen between. It suggests a search process, almost scientific in nature. "Maximize your impact," while mathematically similar, feels more abstract - it's what you do after you've already chosen your path, not the exciting process of discovery itself.

There's also something about the word "find" that matters. It frames the reader as an explorer or researcher, not just an executor. Compare "find the most effective ways" to a hypothetical "use the most effective ways" - I suspect the former would still win. The discovery framing makes people feel like investigators rather than followers.

This pattern appears everywhere. Consider how "evidence-based medicine" caught on while "scientific medicine" didn't, or how "growth mindset" spread faster than "belief in malleable intelligence." The winning framings tend to be those that make abstract concepts feel tangible and position the audience as active participants rather than passive recipients.

The most successful framings seem to offer both intellectual clarity and emotional resonance - they make you feel smart for understanding them while also making you feel capable of action. "Most effective" does both: it's precise enough to feel rigorous but accessible enough to feel achievable.

Thanks Micaella!

We'll give some thought to the best way to approach this. One complicating factor is that the LMICs are very heterogeneous (e.g. we might expect substantial differences between the results for Brazil, China, and Afghanistan). 

Overall, before looking into this more, I can note that all LMICs make up about 7% of the total sample, and about half of these are Brazil, India, China and the Philippines.

Thanks Oscar!

Unfortunately, I don't think that simply excluding smaller countries would be a valid approach. This would lose important data and potentially unfairly exclude smaller countries that are consistently over (or under) performing. And it would potentially distort the true relationship between different predictors and EAs per capita, when we're trying to interpret the pattern of results.

Below, I've shown the rank-order correlations between EAs per capita across years, which are reasonably strong- there is some real consistency, as I noted above- but not amazing, as we see in my plot above.

I think, on the whole, simply looking at the highest EAs per capita countries within a given year is a risky endeavour for the reasons above, and it's better to look at patterns across years and across the full range of countries. 

For example, here are the countries in the top 10 across years, excluding the most recent year (this is from an earlier private report we did).

As you can see, there's some consistency, but also a lot that would likely be misleading if you only looked within a given year's data. Many of these countries go from literally 'top 10 EAs per capita' one year to 0 EAs the next.

Thanks!

Yes, we might do a separate post about EAs per capita across years. But, as we've commented previously, the metric risks being very noisy. So, when you are looking at the countries with the highest EAs per capita, within any single year, you will often see some smaller countries appear to be enormous over-performers, and then not the next, when there's only 1 or 2 respondents difference either way.

Thanks for your question. Yes, these show the distribution for E2G people only (otherwise these plots could not inform us about the E2G question).

Donation_w shows something like 60% (no y scale so not sure) of population don't give at all, is that right?

Only 12.8% are literally donating $0. But a larger percentage are donating close to $0 (31% donating <$500, 38.3% donating <$1000). And around 10% give $20K or more?

You can tell from the median of $2000 that 60% of people are not donating $0. The 60th percentile is around $4000.

20.7% were giving $20,000 or more.
