Epistemic status: grumpy, not committed.
There was quite a lot of discussion of the karma system in the comments to the forum 2.0 announcement, but it didn’t seem very conclusive and as far as I know, hasn’t been publicly discussed since.
That seems enough concern that it’s worth revisiting. My worries are:
- Karma concentration exacerbates groupthink by allowing a relatively small number of people to influence which threads and comments have greatest visibility
- It leads to substantial karma inflation over time, strongly biasing recent posts to get more upvotes
Point 1) was discussed a lot in the original comments. The response was that because it’s a pseudo-logarithmic scale, this shouldn’t be much of a concern. I think we now have reasons to be sceptical of this response:
- There are plenty of people with quite powerful upvotes now - mine are currently worth 5 karma, very close to 6, and I’ve posted less than a dozen top level posts. That will give me 3-6 times the strong voting power of a forum beginner, which seems like way too much.
- While top level posts are the main concern, comments get a much lower level of interest, so the effect of one or two strong votes can stand out much more if you’re skimming through them.
- The people with the highest karma naturally tend to be the most active users, who’re likely already the most committed EAs. This means we already have a natural source of groupthink (assuming the more committed you are to a social group the more likely you are to have bought into any given belief it tends to hold). So groupthinky posts would already tend to get more attention, and having these active users have greater voting power multiplies this effect.
Point 2) is confounded by the movement and user base having grown, so a higher proportion of posts having been made in later years, when there were more potential upvoters. Nonetheless, unless you believe that the number of posts has proliferated faster than the number of users (so that karma is stretched evenly), it seems self-evident that there is at least some degree of karmic inflation.
So my current stance is that, while the magnitude of both effects is difficult to gauge because of complementary factors, both effects are probably in themselves net negative, and therefore things we should not be using tools to complement - we might even want to actively counteract them. I don’t have a specific fix in mind, though plenty were discussed in the comments section linked above. This is just a quick post to encourage discussion of alternative… so over to you, commenters!
Here's a hopefully helpful suggestion...
Turn off the automated karma system, and replace it with a prominent section where the mods highlight their favorite posts. The editors certainly have the right to steer the course of their own forum, and I would personally prefer their analysis and judgement to that of click happy anonymous unknown voters, who may not have even read the posts they are voting on.
So, for example, if I wanted my posts to have prominent placement on the forum, I would have to address the topics of most interest to the editors, and do so in a way which they find to be a useful contribution. You know, nothing new here, this is how most publications work.
As an almost geezer who has been thinking and writing about such subjects for decades, I find it somewhat discouraging that my reputation on the forum is, to some significant degree, being governed by many who are a third to a half my age, and maybe weren't even born yet when my thinking and writing journey began.
If the karma system is to remain, require voters to at least make some brief explanation of their vote, so that future readers will have some opportunity to evaluate the quality of the vote. Can the voter provide at least some evidence that they actually read the article? If not, the karma system is just a high school popularity contest, imho.
