> They’ve focused a lot on IQ and personality — both constructs which were designed to be robust, i.e. hard to change, over time.

I thought this was an interesting observation that suggests that a lot of “conclusions” in this space are actually tautologies.

If nurture easily affected personality, we wouldn’t call it “personality” - what we call personality is exactly that which is unchanging in the face of a dynamic environment.

I am of the exact opposite opinion, given how much peoples personalities can change given input (think of someone spending all their time alone, and being depressed, changing their lifestyle towards going out every few days to hang out with new friends, and reportedly now having a "cheery personality", or simply someone with no passions discovering theirs, and then feeling like there is meaning to life).

As an adult, yes. As a child, no. Personality takes time to form, infants aren't born with strong opinions or takes on any particular subjects.

Do you have kids? They absolutely have noticeable personalities before their first birthday.
