Most individuals are heavily constrained by income. They're spending the majority of their time and energy on generating an income, which is usually low-impact. Meanwhile, as EA grows, the inferential distance one needs to cover to become able to contribute is growing.
By "bridging the inferential gap", I don't just mean learning the basics of EA, but also putting in the time to find highly impactful ideas for projects and learning the skills required to execute them. I would wager that it is many times easier to bridge this gap if someone is working on it full-time. For the sake of simplicity, I'd like to focus on individuals who are self-starting, i.e. all they need is an income and they can take care of the rest.
So let's divide self-starting EA's into three buckets.
A) the ones who are already working on effective projects full-time through employment or a grant
B) the ones who are not working on effective projects, but would put themselves in that position through self-study if they had a year's runway
C) the ones who would not be able to work on effective projects even after a year of self-study
I have three related questions:
- How large is bucket B? How large is it relative to bucket A?
- How can we identify individuals that belong in bucket B?
- If we do identify such an individual, under what conditions is it cost-effective to throw a year's salary at them to let them figure things out?
I am pretty pessimistic about the number of people who aren't in a position to contribute to the world's most pressing problems today, but could readily contribute with a year of self-study.
I think the biggest constraint for having more people working on EA projects is management and leadership capacity. But those aren't things you can (solely) self-study; you need to practice management and leadership in order to get good at them.
I am most optimistic about a year of self-study being useful if someone already has a proven track record of really established skills (whether inside the EA community or outside) and wants to pivot to apply those skills to a different situation. But in those cases I would often expect the person to get hired and learn on the job, or to get a grant for whatever their new project will be with some learning time built in.
tl;dr I think group B is small.
The best thing they can do is probably to lead a project, either through paid work or as a volunteer.
Another good thing would be to speak to a mentor about their leadership work.
When those two things are already happening, books or courses can be really useful. But without practicing leadership and getting regular feedback, I don't expect very good returns from independent study.
(The exception would be someone who's already working at an executive level and wants to take a secondment for personal study and then return to a similar role - the fact that they've already gotten a lot of leadership experience and feedback makes me more positive about the value of them taking time off to study and reflect.)
