If someone uses their brainpower to reliably win, but isn’t interested in helping others do the same, I think you could say something like “they are rationalists, but not our kind of rationalists”.
I’m not sure this is even reasonable. There’s a quiet majority of people on this site and other rationality blogs and in the real world (including Dominic Cummings, apparently) who learn these techniques and use their rationalist knowledge to “win.” And they don’t give back, other than their actions on the world stage. And personally, I think that’s okay. Not everyone needs to take on the role of teacher.

FWIW I agree with this, but it wasn’t necessary to the point I was making and I didn’t feel like defending it.
