It would be really convenient if rationality, the meme-cluster that we most enjoy and are best-equipped to participate in, also happened to be the best for winning at life.

I think this is the strongest point in the whole argument.

Data point: I brought my parents to a Mountain View LW meetup. My parents aren't religious, and my dad is a biochemist that studies DNA repair mechanisms; they define themselves by their skepticism and emphasis on science. So the perfect target audience. But they seemed unenthusiastic, that it was by and for tech-savvy smart young adults but not really for the population as a whole.

This is the most coherent argument I\ve seen against memeticizing Less Wrong. Thank you.
