has anyone actually gotten smarter, in the past few years, by studying rationality?

I feel I’ve learned a lot about prob­lem solv­ing from less wrong (and HPMOR in par­tic­u­lar). be con­crete, hold off on propos­ing solu­tions, et cetera. The effect*, un­for­tu­nately, doesn’t seem to be as much as I had hoped.

Small in­creases in in­tel­li­gence are ex­tremely gen­eral and even re­cur­sive, so it feels worth the effort. But, I found al­ter­na­tives much more effec­tive (though still mod­est) then study­ing/​dis­cussing/​ap­ply­ing the se­quences. like med­i­ta­tion or smart drugs.

I’m in­ter­ested in other less­wrongers ex­pe­riences in cog­ni­tive en­hance­ment.

* by “smarter” I mean “bet­ter at prob­lem solv­ing”, where ex­am­ples of “prob­lems” are writ­ing a pro­gram, find­ing the right thing to say to re­solve in­ter­per­sonal con­flict, mem­o­riz­ing some ran­dom fact quickly and then re­call­ing it quickly/​vividly. let me know if you want fur­ther clar­ifi­ca­tion.
