And a lot of it is culturally loaded. Im sure the average paleolithic hunter gatherer was smarter than me because they have to constantly solve complex problems. While people today rely on civilization to take on the load.

We dont actually do t need to be that intelligent know a days. And actually very few people relly care about it. For example there is some disiese going around that has about 7% chance of leaving you mentally handicapped. And you can catch it reapeatedly. No one really cares. Because they never came to a situation were their inherent intelligence was the bottleneck to solve a problem. Once eventually everyone loses 10or 20% of their intelligence they will still be fine.

So most of these asholes going woe is me im so samart. 1-Are not really that smart. 2-inherent phisiological limitations to cognitive avility have never been an actual limitation in their lives.

The iq is bullshit in the sense the the tests are bullshit. Only the part testing working memory relates to those innate charachteristics.
