TL;DR: Karma overrates “lowest-common-denominator” posts that interest a large fraction of the community, leading to some issues. We list some potential solutions at the bottom.
Please see the disclaimer at the bottom of the post.
Posts that interest everyone — or discussions where everyone has an opinion — tend to get a lot more Forum karma (and attention) than niche posts.
These posts tend to be
- about the EA community
- accessible to everyone, or on topics where everyone has an opinion
Why does this happen?
There are different groups with different niche interests, but an overlapping interest in the EA community:

When a post about the EA community is published, many people might have opinions, and many people feel that they can vote on the post. Most people upvote, so more people voting usually means that a post will get higher karma.
Similarly, if the topic of the post is something that doesn’t require particular expertise to have an opinion about, lots of people feel like they can weigh in. You can think of these as “lowest-common-denominator posts.” This is related to bike-shedding.

This leads to some issues
- This misleads people about what the Forum — and the EA community — cares about
- 10 of the 10 highest karma posts from 2022 were community posts, even though less than ⅓ of total karma went to community posts.
- When someone is trying to evaluate the quality of the Forum, they often go to the list of top posts and evaluate those. This seems like a very reasonable thing to do, but it's actually giving a very skewed picture of what happens on the Forum.
- Because discussions about the community seem to be so highly valued by Forum readers, people might accidentally start to value community-oriented topics more themselves, and drift away from real-world issues
- Imagine an author posting about some issue with RCTs that’s relevant to their work — they’ll get a bit of engagement, some appreciation, and maybe some questions. Then they write a quick post about the font on the Forum — suddenly everyone has an opinion and they get loads of karma. Unconsciously, they might view this as an indicator that the community values the second post more than the first. If this happens repeatedly or they see this happening, they might shift towards that view themselves if they defer even a bit to the community’s view.
- Now imagine this happening on the scale of the thousands of people who use the Forum; these small updates add up.
- This directs even more attention to community-oriented, low-barrier topics, and away from niche topics and topics that are more complex, which might be more valuable to discuss
- Karma is used for sorting the Frontpage: higher-rated posts stay on the Frontpage for longer. This is useful, as it tends to hide the most irrelevant posts, and generally boosts higher quality content — more people see the better posts.
- But because posts that hit the middle sections in the Venn diagrams above get more karma, they tend to stick around for longer, which then gets them more karma, etc.
(We didn't try to make this list of issues as exhaustive as possible.)
Note that karma is not perfect even within a much more specific topic — pretty random factors can affect a Forum post’s karma, and readers aren’t always great at voting, but that is a separate issue. (We might write a post about it later.)
Solutions we’re considering or exploring
- Create something like a subforum or separate tab for “community opinion” posts, and filter them out from the Frontpage by default
- Or otherwise move in this direction
- Rename “Top” sorting to more clearly indicate what karma actually measures
- We tend to have a somewhat higher bar for sharing “community” posts in places like the Digest, largely for these reasons
Note: We (Lizka and Ben) think most of our coworkers on the CEA Online Team more-or-less agree with the post, but there are a variety of opinions. We’re currently at 90%+ that we will do something to address this phenomenon, but at much lower confidence about what specific thing we will do.
Somewhat ironically, given all the strong upvotes that this is getting, I want to (gently) push back a bit. I would ask those who disagree with me to not downvote me too strongly[1] or at least explain why (disagree vote away though).
I feel like there's a mostly unstated opinion in this post that the posts getting high karma are actually not the highest quality ones, or the ones that the community cares about, or the ones that Forum readers should care about. I think terms like "lowest common denominator" and "bikeshedding" imply this quite heavily. But my fear is that this could be used, perhaps unintentionally, to shut down debates on issues, especially from newer users or those new to EA.
For example, the top-voted comment on the Wytham Abbey post writes the whole community response off as bikeshedding[2]. This comment seems linked to the use of 'bad epistemics' which I feel often assumes a conclusion. See this post, which I mostly agree with, for further discussion on this issue. My emotional reaction is that it all feels a bit like subtweeting[3], unless there are examples given of "this specific post had too much karma and was over-rated by the forum" and "this specific post was undervalued and dropped from the frontpage too quickly".
Furthermore, it's not clear that valuing community-oriented topics is bad in-and-of-itself. "Building effective altruism" is currently number 3 on 80,000 Hour's list of most pressing problems. To the extent that these posts involving the whole community lead to community improvement, then it might be positive. I'm not necessarily arguing that this is true, but I do dispute that the issues discussed in community posts are not 'real-world' issues.
As for the practical solutions proposed, I think 2 & 3 sound fine. Potentially you could add a section similar to 'Recommendations' that might be something like 'CEA Online Choice' or 'Curated' or something - where the Online Team selects high-quality, valuable niche posts that aren't getting viewed and displays them more prominently?
Finally, this reminds me of the discourse around 'Open EA Global' and the CEA response. There seemed to be a misunderstanding between a large part of the community and CEA regarding what the purpose of EAG was, and perhaps this is true of the forum as well? I would welcome thoughts on this or any of the above, or people providing more information and corrections to what I've written
Yeah, I hate how much this sounds like "I know I'll get downvoted for this but..." too smh
Though I was pleased to see that there was strong pushback to this characterisation in the replies
Personal to me. I don't want to imply that 'subtweeting' is actually happening
I can see how all of this can feel related to the discussion about "bad epistemics" or a claim that the community as a whole is overly navel-gazing, etc. Thanks for flagging that you're concerned about this.
To be clear, though, one of the issues here (and use of the term "bike-shedding") is more specific than those broader discussions. I think, given whatever it is that the community cares about (without opining about whether that prioritization is "correct"), the issues described in the post will appear.
Take the example of the Forum itself as ... (read more)
