I invite you to ask anything you’re wondering about that’s remotely related to effective altruism. There’s no such thing as a question too basic.
Try to ask your first batch of questions by Monday, October 17 (so that people who want to answer questions can know to make some time around then).
Everyone is encouraged to answer (see more on this below). There’s a small prize for questions and answers. [Edit: prize-winning questions and answers are announced here.]
This is a test thread — we might try variations on it later.[1]
How to ask questions
Ask anything you’re wondering about that has anything to do with effective altruism.
More guidelines:
- Try to post each question as a separate "Answer"-style comment on the post.
- There’s no such thing as a question too basic (or too niche!).
- Follow the Forum norms.[2]
I encourage everyone to view asking questions that you think might be “too basic” as a public service; if you’re wondering about something, others might, too.
Example questions
- I’m confused about Bayesianism; does anyone have a good explainer?
- Is everyone in EA a utilitarian?
- Why would we care about neglectedness?
- Why do people work on farmed animal welfare specifically vs just working on animal welfare?
- Is EA an organization?
- How do people justify working on things that will happen in the future when there’s suffering happening today?
- Why do people think that forecasting or prediction markets work? (Or, do they?)
How to answer questions
Anyone can answer questions, and there can (and should) be multiple answers to many of the questions. I encourage you to point people to relevant resources — you don’t have to write everything from scratch!
Norms and guides:
- Be generous and welcoming (no patronizing).
- Honestly share your uncertainty about your answer.
- Feel free to give partial answers or point people to relevant resources if you can’t or don’t have time to give a full answer.
- Don’t represent your answer as an official answer on behalf of effective altruism.
- Keep to the Forum norms.
You should feel free and welcome to vote on the answers (upvote the ones you like!). You can also give answers to questions that already have an answer, or reply to existing answers, especially if you disagree.
The (small) prize
This isn’t a competition, but just to help kick-start this thing (and to celebrate excellent discussion at the end), the Forum team will award $100 each to my 5 favorite questions, and $100 each to my 5 favorite answers (questions posted before Monday, October 17, answers posted before October 24).
I’ll post a comment on this post with the results, and edit the post itself to list the winners. [Edit: prize-winning questions and answers are announced here.]

Your feedback is very welcome! We’re considering trying out themed versions in the future; e.g. “Ask anything about cause prioritization” or “Ask anything about AI safety.”
We’re hoping this thread will help get clarity and good answers, counter some impostor syndrome that exists in the community (see 1 and 2), potentially rediscover some good resources, and generally make us collectively more willing to ask about things that confuse us.

If I think something is rude or otherwise norm-breaking, I’ll delete it.
What are the most ambitious EA projects that failed?
If we're encouraged to be more ambitious, it would be nice to have a very rough idea of how cost-effective ambition is itself. Essentially, I'd love to find or arrive at an intuitive/quantitative estimate of the following variables:
In other words, is the reason why we don't see more big wins in EA that people aren't ambitious enough, or are big wins just really unlikely? Are we bottlenecked by ambition?
For this reason, I think it could be personally[2] valuable to see a list,[3] one that tries hard to be comprehensive, of failed, successfwl, and abandoned projects. Failing that, I'd love to just hear anecdotes.
Carrick Flynn's political campaign is a prototypical example. Others include CFAR, Arbital, RAISE. Other ideas include published EA-inspired books that went under the radar, papers that intended to persuade academics but failed, or even just earning-to-give-motivated failed entrepreneurs, etc.
I currently seem to have a disproportionately high prior on the "hit rate" for really high ambition, just because I know some success stories (e.g. Sam Bankman-Fried), and this is despite the fact that I don't see much extreme ambition in the water generally.
Such a list could also be usefwl for publicly celebrating failure and communicating that we're appreciative of people who risked trying. : )
