This is intended as a sequel to my old Biodeterminist’s Guide To Parenting. It’s less ambitious, in that it focuses only on pregnancy; but also more ambitious, in that it tries to be right. I wrote Biodeterminist’s Guide in 2012, before the replication crisis was well understood, and I had too low a bar for including random crazy hypotheses.

On the other hand, everyone else has too high a bar for including random crazy hypotheses! If you look at standard pregnancy advice, it’s all stuff like “take prenatal vitamins” and “avoid alcohol” and “don’t strike your abdomen repeatedly with blunt objects”. It’s fine, but it’s the equivalent of college counselors who say “get good grades and try hard on the SAT.” Meanwhile, there are tiger mothers who are making their kids play oboe 10 hours/day because they heard the Harvard music department has clout with Admissions and is short on oboists. What’s the pregnancy-advice version of that?

That’s what we’re doing here. Do not take this guide as a list of things that you have to do, or (God forbid) that you should feel guilty for not doing. Take it as a list of the most extreme things you could do if you were neurotic and had no sense of proportion.
