Chimpanzees are very clever at the level of being able to make observations and remember things. They can remember better than humans can, but they, again, are inept at handling interpersonal relationships.
Chimpanzees aren't that bad at handling interpersonal relationships. Especially compared to their cleverness in other areas. They have approximately the opposite problem as the autistics.
I am genuinely surprised. The parent is the last of my recent comments that I would expect to be disapproved of but it managed to get to -2. And not out of any evident general assassination either from what I can tell. That usually means that either people disagree strongly or, more commonly, that it goes against people's politics. Since I am not aware of any group that would find that particularly objectionable the obvious hypotheses are either two people somehow disagree about the relative strengths of chimpanzees or the meaning of my words are less tran...
In their 2011 chapter for the Cambridge Handbook of Intelligence, Stanovich et al. review the evidence suggesting that intelligence and rationality are not the same thing and that rationality is often more important than intelligence. They then lament the fact that there are no standard tests for measuring one's "Rationality Quotient." Then they take a few steps toward such a thing by suggesting some important rationality skills (actively open-minded thinking, fine-grained emotional regulation, tendency to seek information and fully process it, etc.) and rationality 'mindware' (probability theory, scientific process, economic thinking, etc.).
Here are those pages in particular: first a graphic of some important rationality skills and mindware, and then a table of the components of rational thought: rationality components, relevant literature citations, and example word problems that would test for each rationality component.
