How big an impact do genes have on the potential of an individual to become a rationalist?
Too big. If rationality was reliably taught, it wouldn’t require more-than-normal fluid intelligence to have a nontrivial probability of turning into a systematic rationalist.
On the one hand, there’s some evidence that religiosity is partly heritable. On the other hand, this correlation between genes and religiosity is without manipulating the educational environment.
There’s an apocryphal quote associated with the Jesuits: “Give me a child up to the age of seven and I will give you the man.” Intense education would overwhelm the genetic factors.
In that case, it’s not just about memes but about genes.

One hopes. I don’t know if it’s possible to generalize on this point though. With some education takes, with some, it doesn’t.
