studies have been done in subsistence farming societies where researchers measure iq during harvest and during the time of scarcity of sustenance. study participants had higher iq when they were flush with harvest and lower iq as their stock of food was almost gone
I am not going to get into an extended argument with you over this.
I would have to see the study to scrutinize it.
Leaker, I know you see a study and you think
"That was done by smart people; it must be right."
When I see a study I think
"There is an extremely low chance that study was done by people as intelligent as me. I want to see the data, methodology, and their reasoning for reaching the conclusions."
There is a high probability that the study to which you referred demonstrated that
in the short term people who are well-nourished will perform better in IQ tests than people who are not. To most people, that is common sense. When writing
any test, it is a good idea to eat well going into it, get a few good nights sleep, etc.. But that is to do well in a test
in the short term. In other words, being hungry and sleepy might make you
perform poorly, but it does not actually make you less intelligent
permanently.
