This seems to be false. See for example here.
Those biologists are enthusiastic about it, I know. But they simply don't understand what information means, IMHO.
A few years ago, some of them frequently claimed, that there is a ridiculously big number of bytes stored in human memory. Something much greater than goes inside the Beckenstein's bound for the planet, let alone the head.
In my humble opinion, and with all the respect, they don't know what they are talking about.
I'm confused. Are you saying that they are wrong when they say that womb environment impacts intelligence and sexual preference? Is it possible that there's an issue of definitions going on here about what is meant by "about zero"?
Do you have a citation for this? I'd be curious to see that.
There's one estimate in the While Brain Emulation roadmap from (Wang, Liu et al., 2003) estimating that the brain has a computational capacity with 10^8432^ bits of memory.
Sandberg & Bostrom sardonicly note in a footnote that 'This information density is far larger than the Bekenstein black hole entropy bound on the information content in material systems (Bekenstein, 1981).'
I'm not surprised that such estimates exist. What I'm more doubtful is the claim that such bounds were "frequently claimed".
Can't find it now, I am sorry. But I remember the number 2^8000 or there about bytes, mentioned a few years ago as an estimation by some scientist. Neurologist. Now it is impossible to find it, since Google can't search "2^8* ... bytes ... brains" type of a string. Or some regular expressions or something.
I am saying, that there is at the most a very tiny amount of the information flow, even if the womb can make you smarter or dumber. If a lightning strikes and makes somebody a 10 IQ points smarter - what I can see as a possibility - the amount of information by the thunder is about zero.
