Communities: A single moderator is often superior to the wisdom of crowds

Less Wrong is a community where I believe that most of the people would accept that “knowledge is power”. In our modern age, the internet provides some of the best tools for distributing this information. Many tools, such as Reddit, StackExchange or Less Wrong itself, use voting as a method to determine the highest quality content.

One situation this works well for is when an area is niche (ie. http://​​www.reddit.com/​​r/​​criticaltheory, http://​​www.reddit.com/​​r/​​neuroscience). Because these areas are so niche, the vast majority of people who decide to participate in these forums will have at least a minimum amount of knowledge, meaning that the content can remain high quality even where there are large numbers of participants.

Another situation is when a forum is highly moderated. Examples include Less Wrong, which bans politics, Skeptics Stackexchange, which requires references and Ask Historians where sources aren’t mandatory, but you’re expected to be able to back up your claims on demand.

What is interesting is when an area is neither niche, nor easy to be objective about. Take for example https://​​www.reddit.com/​​r/​​socialskills, https://​​www.reddit.com/​​r/​​dating or personal development (https://​​www.reddit.com/​​r/​​decidingtobebetter). In these areas, large numbers of people come along and post various articles and questions that interest them. Unfortunately, there are often huge amounts of overlap between the articles that are posted. Between articles telling you to “be yourself”, “have confidence in yourself” and to “step out of your comfort zone” it is very hard to find articles telling you things you haven’t seen before. It is very hard to find new content buried among all of the noise.

This is a shame because social skills, dating and personal development are all important areas. Sites like Reddit theoretically allow you to access the best content available on the web, but this benefit doesn’t accrue if all the articles are saying the same thing. What is particularly ironic is that it wouldn’t be too hard for a single person to do a much better job of filtering this content. All they would have to do, is filter out the articles that are duplicates of articles that are already existing. Sure they wouldn’t be perfect and a significant percentage of useful articles would be filtered out due to their biases, but this would still be superior to the status quo where only a small number of people who find these sub-reddits actually gain consistent value from them because of all of the duplicate content.

Unfortunately, this kind of site is unlikely to be set up, because people would feel it was unfair for a single moderator to have this arbitrary power. I can understand this to some degree, as in, I would be annoyed when I submitted articles and I thought that they were wrongly rejected, but the amount of value that could be gained from such a site would be immense. I don’t believe that a particularly high level of competence would be required from the moderator. One question is what happens if the moderator is bad? This could be detrimental in the short term, but the moderator would likely be voted out very quickly if they weren’t doing a good job.

I’ve argued that even a single moderator with the sole ability to choose the articles and a reasonable level of competence could do better than current sites. However, reading all those articles could be a lot of work, so perhaps a few moderators could be selected to divide up the work and give feedback to each other on whether or not they thought an article was new enough to be deserving of inclusion. Perhaps there is a more democratic solution to this—I would love for this to exist—but the solution I have proposed is likely to work due to its simplicity.
