Medical Biological limits to a Human's G - What's the limit?

AI Thread Summary
The discussion centers on the limits of human cognitive ability, specifically regarding the G factor, which is a measure of general intelligence. It questions whether there is a biological limit to this cognitive ability and if such limits can be estimated based on current neurological understanding. The conversation highlights that while IQ tests measure relative performance, the G factor itself is defined finitely, suggesting an inherent limit to cognitive capacity. Participants are encouraged to refer to existing threads on the topic to avoid redundancy, as similar discussions have already taken place. The importance of utilizing prior discussions for further exploration is emphasized, alongside a welcome to new participants in the forum.

Hello. I've always wondered about the limit to Human's ability to think complexly, and what would be incorporated in that ability to think in such complicated terms. The general measurement used to quantify this is usually the IQ test, which is a measurement that depends solely on one's relative performance to the normed sample. But what I'm asking about is the G factor, regardless of one's relative G to another's. Is there a biological limit to one's 'G', or cognitive ability, and can it be accurately estimated? In the strictest sense, it would seem impossible for someone's G to be "infinite" since the concept itself is defined finitely, so there has to be a limit - But what are the bio/neuro-logical limits on this G factor, and can this 'maximum' G factor limit be approximated using academia's current understanding of neurology?

I know the search feature is not working properly, but please at least check a few pages in a forum for related topics before posting. This topic has been discussed before, and a similar one just a few posts down from yours has just been locked, as will this one since it is redundant with previous threads.

Two of the most recent threads are still open. Please read those for the answer to your question, and continue the discussion, if necessary, in the already existing threads rather than start a new one.

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
