Obligatory link to Scott Alexander's "Ambijectivity" regarding the contentiousness of defining great art.
I agree that that the word ‘populism’ is very prone to misunderstandings but I think the term 'technocracy' is acceptably precise. While precision is important, I think we should balance this against the benefits of using more common words, which make it easier for the reader to make connections with other arguments in favour of or against a concept.
I should clarify: I think the misunderstandings are symptoms of a deeper problem, which is that the concept of "technocracy" is too many different things rolled into one word. This isn't about jargon vs. non-jargon; substituting a more jargon-y word doesn't help. (I think this is part of why it's taken on such negative connotations, because people can easily roll anything they don't like into it; that's not itself a strong reason not to use it, but it's illustrative.)
"Technocracy" works okay-ish in contexts like this thread where we're all mostly speaking in vague generalities to begin with, but when discussing specific policies or even principles for thinking about policy, "I think this is too technocratic" just isn't helpful. More specific things like "I think this policy exposes the people executing it to too much moral hazard", or "I think this policy is too likely to have unknown-unknowns that some other group of people could have warned us about", are better. Indeed, those are very different concerns and I see no reason to believe that EA-in-general errs the same amount, or even in the same direction, for each of them. (If words like "moral hazard" are too jargon-y then you can just replace them with their plain-English definitions.)
I also think that EAs haven't sufficiently considered populism as a tool to deal with moral uncertainty.
I agree that there hasn't been much systematic study of this question (at least not that I'm aware of), and maybe there should be. That being said, I'm deeply skeptical that it's a good idea, and I think most other EAs who've considered it are too, which is why you don't hear it proposed very often.
Some reasons for this include:
I am not convinced that there is much thinking amongst EAs about experts misusing technocracy by focusing on their own interests
In at least one particular case (AI safety), a somewhat deliberate decision was made to deemphasize this concern, because of a belief not only that it's not the most important concern, but that focus on it is actively harmful to concerns that are more important.
For example, Eliezer (who pioneered the argument for worrying about accident risk from advanced AI) contends that the founding of OpenAI was an instance of this. In his telling, DeepMind had previously had a quasi-monopoly on capacity to make progress towards transformative AI, because no other well-resourced actors were working seriously on the problem. This allowed them to have a careful culture about safety and to serve as a coordination point, so that all safety-conscious AI researchers around the world could work towards the common goal of not deploying something dangerous. Elon Musk was dissatisfied with the amount of moral hazard that this exposed DeepMind CEO Demis Hassabis to, so he founded a competing organization with the explicit goal of eliminating moral hazard from advanced AI by giving control of it to everyone (as is reflected in their name, though they later pivoted away from this around the time Musk stopped being involved). This forced both organizations to put more emphasis on development speed, lest the other one build transformative AI first and do something bad with it, and encouraged other actors to do likewise by destroying the coordination point. The result is a race to the precipice [PDF], where everyone has to compromise on safety and therefore accident risk is dramatically more likely.
More generally, politics is fun to argue about and people like to look for villains, so there's a risk that emphasis on person-vs.-person conflicts sucks up all the oxygen and accident risk doesn't get addressed. This is applicable more broadly than just AI safety, and is at least an argument for being careful about certain flavors of discourse.
One prominent dissenter from this consensus is Andrew Critch from CHAI; you can read the comments on his post for some thoughtful argument among EAs working on AI safety about this question.
I'm not sure what to think about other kinds of policies that EA cares about; I can't think of very many off the top of my head that have large amounts of the kind of moral hazard that advanced AI has. This seems to me like another kind of question that has to be answered on a case-by-case basis.
Honestly it seems kind of weird that on the EA Forum there isn't just a checkbox for this.
