The anti-probiotic piece didn't have any details about how the studies were constructed, so there's no way to say whether they were reasonable.

That death of the newspapers graph is just the top chunks, so as to make the change look larger. How to Lie with Statistics is just as relevant as it ever was.

Twins start out with a shared environment in the womb-- it's hard to say how important this is, but it might have some contribution. On the other hand, it wouldn't do much for the hardcore freewill supporters.

Womb environment doesn't affect tameness in foxes.

There is still the possibility that the hormones sloshing around during pregnancy might alter fetal development and hence behaviour. Ruling this out requires switching embryos between mothers, which has yet to be done in rats. It has, however, been done in the silver foxes and had no obvious effect.
