I think the important questions are "what type of information?" and "what would they be doing otherwise?"

If you're interested in development economics and the choice is between reading everything posted on the Forum and taking a micromasters course in data and development*, I'd suggest the latter. But if it's a choice between scrolling Facebook and learning about EA, learning about EA is probably more useful.

Quick take:

I think that in theory, if things were being done quite well and we had a lot of resources, we should be in a situation where most EAs really don't need much outside of maybe 20-200 hours of EA-specific information; after which focusing more on productivity and career-specific skills would result in greater gains.

Right now things are more messy. There's no great one textbook, and the theory is very much still in development. As such, it probably does require spending more time, but I'm not sure how much more time.

I don't know if you consider these "EA" concepts, but I do have a soft spot for many things that have somewhat come out of this community but aren't specific to EA. These are more things I really wish everyone knew, and they could take some time to learn. Some ideas here include:

• "Good" epistemics (This is vague, but the area is complicated)
• Bayesian reasoning
• Emotional maturity
• Applied Stoicism (very similar to managing one's own emotions well)
• Cost-benefit analyses and related thinking
• Pragmatic online etiquette

If we were in a culture that was firmly attached to beliefs around the human-sacrificing god Zordotron, I would think that education to carefully remove both the belief and many of the practices that are caused by that belief, would be quite useful, but also quite difficult. Doing so may be decently orthogonal to learning about EA, but would seem like generally a good thing.

I believe that common culture taught in schools and media is probably not quite as bizarre, but definitely substantially incorrect in ways that are incredibly difficult to rectify.

My initial thoughts are similar to those of Adam and Linch, but I'll post them here anyway, despite possible redundancy:

• If someone learns about an EA concept in detail, they might be able to use that to generate unique insights or follow-up, even if many other people already knew a lot about that concept. Reasons this might happen:
  • They are more up-to-date on the concept than others who learned about it a while ago (e.g. they've read very recent studies related to the concept)
  • They bring unique "outside knowledge" to the concept (e.g. they have a background in sociology, which none of the other people who knew about the concept had)
  • They have the time/skill to write out what they know in a way that a much wider audience can understand without much effort, which wasn't the case for the others
  • They have access to funding/other resources that the others didn't have (e.g. they can pay for a massive survey to gather direct data that furthers their knowledge, or they're in touch with experts in the relevant field who can help to deepen their knowledge)
• Learning about concepts in detail seems important if someone might pursue a career in one of several fields. I'd want them to make such a decision based on a lot of firsthand information about each field, in addition to whatever shared resources the EA community can contribute (as personal characteristics and background play a big role in how well someone's career will go in a given field)
• Someone who learns about a concept in detail might wind up explaining it (in less detail) to people they know personally who might otherwise never learn about it. Even if the community provides many "authoritative" sources of written knowledge, it's still hard to replace the benefit of having someone you know explain something to you and answer your questions in real time.
  • Similarly, they might be able to persuade other people with their combination of knowledge + personal connection. Many members of this community are only here because someone they knew persuaded them to get involved, and I'm guessing that "go read this article" is less persuasive than "let me tell you about this exciting thing that I'm clearly well-informed about"
• Learning about things in detail builds good epistemic habits related to understanding how research works and so on. The more people in EA have good epistemic habits, the less likely it is that we'll miss something obvious or be vulnerable to bad arguments, scams, etc.
