EA Survey 2020: Cause Prioritization
Global Poverty is the highest rated cause overall
We found support for longtermist and meta causes to increase with higher self-reported engagement in EA
We also observed higher support for neartermist causes in non-male respondents across engagement levels, though there was no gender difference in support for longtermist causes among more engaged respondents
Comparing ratings across separate EA surveys, we observe a decrease in support for global poverty over time, and an increase in support for animal welfare and AI risk
Full Scale Responses
Comparing mean ratings across causes
As the same participants rated multiple causes, we used a linear mixed model, with respondent as a random factor, to compare the mean ratings of different causes.
This confirms that the mean rating for Global Poverty is significantly higher than all other causes, followed by Cause Prioritization and Reducing Risks from AI.
AI Risk and Cause Prioritisation receive very similar mean ratings to each other and are the second most highly ranked.
Biosecurity, Climate Change, EA Movement Building and Existential Risk (other) all receive similar ratings (although Biosecurity and Existential Risk (other) do differ significantly).
Animal Welfare and Broad Longtermism are the next highest ranked, followed by Nuclear Security and Meta (not movement building) and Mental Health.
Top Cause Percentages
As in previous years, we report the percentages of respondents rating each cause as the ‘top cause.’ Of course, this is essentially just looking at one level of the responses shown in the graph above. While this leads to simple headline findings (e.g. which cause has the most people rating it ‘top’), it is likely more informative to look at the full range of responses.
One result that may be of particular interest, however, is support for Biosecurity (and pandemic preparedness), given the pandemic. This increased from 4% in 2018 and 2019 to 6% in 2020.
Relationships Between Causes
We explored relationships between ratings of different causes by conducting an exploratory factor analysis. This procedure aims to identify latent factors underlying the data (for example, support for longtermism might be related to support for a number of different longtermist causes).
Across a series of different models, we identified three factors underlying the data, with the same causes associated with them to similar degrees. These were:
Note: Broad longtermism and Animal Welfare only very weakly loaded onto their respective factors.
Exactly how to interpret each factor is, of course, somewhat open to debate, but we think that responses to the causes in each of these different groupings can, to a significant degree, be thought of as reflecting common factors, such as support for existential risk reduction causes or neartermist causes.
Predictors of cause ratings
To simplify analysis, we reduced the ratings of the individual causes above into the three groupings identified by our EFA above (‘longtermist’ ‘meta’ and ’neartermist), by averaging the scores for each of those categories. As before, we used a linear mixed model to account for the fact that respondents each rated multiple causes. We provide the raw average ratings for each individual cause in the tables in Appendix 2.
Another decision we took to simplify the model was to only examine the influence of people’s level of self-reported engagement with EA and gender.
The first plot below simply shows the mean ratings for each of the three broad cause areas across engagement levels. As we can see, average support for Near-termist causes declines with increases in engagement, while support for Longtermist and Meta causes increases.
The next two plots show the same relationship between engagement and cause ratings split by gender (male and non-male respectively). We observed a significant interaction effect between gender, engagement and cause, suggesting that the relationship between engagement and cause ratings varies by gender, though the overall pattern is quite similar.
We have previously observed that non-male respondents seem relatively more supportive of near-termist causes than male respondents, and plotting the male and non-male ratings across engagement levels for each cause separately, we can observe that while the average cause ratings of male and non-male respondents at higher engagement levels are quite similar for longtermism and meta, non-male respondents consistently give higher neartermism ratings across engagement levels.
Cause preferences over time
Comparing cause ratings from year to year is difficult since the cause list has changed over time. Although we have tried to keep categories as similar as possible across years, precisely to facilitate comparisons, we have sometimes added, removed or changed categories, as circumstances changed. The classification we have used for each cause is shown in a chart in the Appendix.
This analysis shows the average cause rating across years, based on the responses in each year’s EA Survey. This is in contrast to showing average ratings across cohorts, i.e. EAs who reported joining EA in a given year. It is important to note that this could still reflect a change in the composition of the EA population or sample, rather than a change in views (i.e. it could be that neartermist EAs who responded in earlier years have dropped out, while longtermist EAs have joined).
Note: there was no EA Survey run in 2016.
The clearest change in average cause ranking since 2015 is a steady decrease for global poverty and increases for AI risk and animal welfare. Cause prioritization, other neartermist, and meta appear to have remained fairly constant. The individual causes under other x-risk were only included from 2018 onward, but have shown a slight increase in rating since it was added to the survey.
Other Cause Areas (open comment)
We also asked respondents, “Are there any other causes you feel should be priorities for the EA community?” After removing 25 unclassifiable responses, we categorized the remaining 442 replies into 41 categories. The category with the most responses is Other which comprises cause areas with only one response, as well as replies that mentioned multiple causes. After Other, the most commonly mentioned causes are safeguarding democracy/preventing authoritarianism and improving decision making/institutional reform. Other commonly mentioned potential causes include improving education, identifying/preventing S-risk, anti-aging research, public health, and reducing inequality.

The annual EA Survey is a project of Rethink Priorities. This post was written by David Moss, and Jacob Schmiess. Thanks to Peter Wildeford and David Reinstein for comments.
We would also like to express our appreciation to the Centre for Effective Altruism for supporting our work. Thanks also to everyone who took and shared the survey.
The full cause labels included in the survey were: Global poverty, Reducing risks from artificial intelligence, Climate change, Cause prioritization, EA movement building, Existential risk (other than AI, biosecurity, or nuclear security), Animal welfare/rights, Broad longtermism (other than existential risks), Biosecurity and pandemic preparedness, Nuclear security, Mental health, Meta (other than EA movement building). ↩︎
The ratings levels were: (1) I do not think any resources should be devoted to this cause, (2) I do not think this is a priority, but should receive some resources, (3) This cause deserves significant resources, but less than the top priorities, (4) This cause should be a near-top priority, (5) This cause should be the top priority. ↩︎

The 2014 EA Survey also asked about cause prioritisation, but only presented respondents with binary response options, rather than the rating scale we have used since 2015. ↩︎
Causes which have remained constant for all surveys are animal welfare, cause prioritization, climate change, AI, global poverty, and meta. Surveys in 2015 and 2017 included non-AI far future and politics as causes. In 2018, we added more fine-grained longtermist/existential risk categories (biosecurity, nuclear security, and existential risk (other). Increasing rationality and decision making was included as a cause for all years prior to 2020. The 2020 EA survey added EA movement building, separate from EA meta, and broad longtermism. ↩︎
