LessWrong is about learning rationality, and applying rationality to interesting problems.
An issue is that solving interesting problems often requires fairly deep technical knowledge of a field. To use rationality to help solving problems (especially as a group), you need both people who have skills in probability/meta-cognition/other-rationality skills, as well as the actual skills directly applicable to whatever problem is under discussion.
But if you show up on LW and post something technical (or even just "specialized") in a field that isn't already well represented on the forum, it'll be hard to have meaningful conversations about it.
Elsewhere on the internet there are probably forums focused on whatever-your-specialization is, but those places won't necessarily have people who know how to integrate evidence and think probabilistically in confusing domains.
So far the LW userbase has a cluster of skills related to AI alignment, some cognitive science, decision theory, etc. If a technical post isn't in one of those fields, you'll probably get better reception if it's somehow "generalist technical" (i.e. in some field that's relevant to a bunch of other fields), or if it somehow starts one inferential unit away from the overall LW userbase.
A plausibly good strategy is to try to recruit a number of people from a given field at once, to try to increase the surface area of "serious" conversations that can happen here.
It might make most sense to recruit from fields that are close enough to the existing vaguely-defined-LW memeplex that they can also get value from existing conversations here.
Anyone have ideas on where to do outreach in this vein? (Separately, perhaps: how to do outreach in this vein?). Or, alternately, anyone have a vague-feeling-of-doom about this entire approach and have alternate suggestions or reasons not to try?
Minor conflict of interest disclaimer: I've recently become much more interested in computational biology and therefore have a personal interest in having more content related to biology in general on LW.
I'd be excited about having more representation from the experimental sciences, e.g. biology, certain areas of physics, chemistry, on LessWrong. I don't have a good sense of how many total LW users come from these fields, but it certainly doesn't seem like many prominent posters/commenters do. The closest thing to a prominent poster who talks about experimental science is Scott Alexander.
My sense from random conversations I've had over the years is that there's a lot of tacit but important knowledge about how to do experimental research and lab work well that isn't written down anywhere and could make for interesting complementary content to the wealth of content on LW about the connection between rationality and doing theory well. There's also an untapped treasure trove of stories about important discoveries in these areas that could make for good LW post series. I'd love to see someone take me through the history of Barbara McClintock's discoveries or the development of CRISPR from a rationalist perspective (i.e. what were the cognitive strategies that went along with discovering these things). There are books on discoveries like this of course, but there are also books on most of the material in the Sequences.
Having more LWers from experimental sciences could also provide a foundation for more detailed discussion of X-risks outside of transformative AI, bio-risks in particular.
In terms of attracting these sorts of people, one challenge is that younger researchers in these areas in particular tend to have long hours due to the demands of lab work and therefore may have less time to post on LW.
We used to have posts like https://www.lesswrong.com/posts/pWi5WmvDcN4Hn7Bo6/even-if-you-have-a-nail-not-all-hammers-are-the-same , so quite a few people would read it.
