This is such a sad and touching commercial. The wife is showing signs of Alzheimer’s but her big brained husband is not. It’s so poignant when he says softly “it’s alright baby”. That’s what real love is.
Big brained people not only have higher IQs all their lives, but I believe their IQs shoot up in old age. It’s not that they’re getting smarter,they get dumber in old age like the rest of us; however they get dumber at a slower rate, and since IQ reflects your rank among your age group, and not your absolute intelligence, their IQs must go up. For example, the husband in that commercial could have even more Alzheimer’s plaques and tangles in his brain than she does, but because his brain is so much bigger than hers, it could take decades for the disease to spread through enough of his brain for symptoms to show. By contrast her brain is small enough that only a few plaques and tangles are enough to compromise most of the brain.
I’ve heard of a woman who couldn’t remember where she parked, and when she asked a police officer for her help, he decided she was no longer competent to drive, which I think was a huge overreaction. If you ever forget where you parked, don’t tell anyone. Take a cab home instead.
But the rank does not change if alzheimer is less in higher IQ people…So IQ stays the same if rank does not change…
“if alzheimer is less in higher IQ people” , sorry I guess you rather said alzheimer is less in “big brained” people. not high IQ…
so high IQ people with smaller brains would loose their ranks… in that case, you are right…
High IQ people are less likely to get dementia as you say, but the correlation is far from perfect, so rank order changes
Even in non-demented people rank order changes
it’s pretty easy to forget where you’ve parked if you park far away from your destination in an unfamiliar locale. it’s happened to me, though i eventually found it. ontop of that it was a rental and i’d parked in the day and walked back at night.
name the SNP and i can search my genome for it pp.
SNPs for PDD…heeheehee.
i finally opened my file.
it’s a 120+ MB .txt file. it’s in 23andme format. there was a free service at Stanford, but it’s defunct or i can’t upload the whole thing, i’ve tried. there’s a $5 service, but it seems shady.
here’s an eentsy teeny weeny excerpt…from the very beginning of the file:

So big-brained people increase their IQ despite that stupid people die earlier. I’d like to know how 75 year old people compare to 25 year old people. Maybe they are smarter.
The moron who argued about additive effect with me should read this to know how he’s wrong. Hsu defends the additive model himself: http://infoproc.blogspot.ca/2015/05/fifty-years-of-twin-studies.html
Pumpkin,
what part you do not understand the correlation between brain size and iq is relatively little and depend other factors??
first, you need standardize the sample, all bio-traits need to be equal, same race, same height, same weight, to analyse iq and brain size. My opinion.
