Didn't Einstein have 20% more neurons in his brain than a regular person? I don't know where I read that,
Who told that? I suggest u not to read any junk sciences unless they can really show physiological and neurological evidences with MRI or something.
First off, if 20% more neurons stuff is true, then you have to prove having neurons will lead to higher IQ.
Secondly, you have to prove Einstein natal with 20% more neurons than normal babies, not due to his postnatal intelligent practices(They can somehow upgrade your brain structure)
Finally, IQ has been already categorized into two kinds:Crystallized Intelligence and Fluid Intelligence, the latter of which is being all the time put nearly all of emphasises on and viciously competed over by human.
As well I have mentioned above IQ itself is just bs and I'd like to say it's more like random index that can destroy or maintain one's confidence, maliciously or encouragingly.
