There was a post (which I unfortunately couldn't locate) that argued that rationalists should aspire to more - that a successful rationalist should be able to master other skills too that make it obvious that being a "rationality master" is something to aspire to.
Several skills such as writing, speech craft and social skills are different from more procedural skills in that they are best learned by observational learning. Strong logic skills don't provide the same advantages here that they do in maths or science - in fact an intermediate level of logic is often a disadvantage as it leads to expecting other people to behave logically.
So if we wish to develop these skills as a community, we would need to develop a repository of examples with notes to explain what principles each example is intended to show. There might be some disagreement as to how applicable each principle is and whether a particular decision is correct - but it would still be far, far better than what else is out there. Unfortunately most communities on the Internet (ie. reddit.com/r/socialskills) end up with huge amounts of rather general advice. This advice is helpful in the beginning, but you quickly get to a stage where you have heard all of it before many, many times. But with examples, even people who are extremely talented may get something out of it.
