Chimps Outwit Humans How? Better Empathy? ESP?

If you’re trying to outwit the competition, it might be better to have been born a chimpanzee. The study involved a simple game called the Inspection Game. To win repeatedly, players have to accurately predict what their opponent will do next.
The game is common in everyday lives. An employee may want to work only when her employer is watching and prefers to play video games when unobserved.
However cleverly you play the Inspection Game, if your opponent is also playing strategically, there is a limit to how often you can win. Unlike humans, chimps learned the game rapidly and nearly attained the predictions for optimal play. They continued to do so even as researchers introduced changes into the game.
Chimpanzees excel at short-term memory; humans find it much more challenging. Further, wherever humans sit on the cooperative/competitive scale, common chimpanzees are more competitive. They continuously update status and dominance hierarchy.
The “cognitive tradeoff” is probably a key. Acquiring capacities such as language and categorization caused human brains to lose other capacities, such as intuiting another’s strategy. In the experiments, humans were not allowed to speak with one another.
Ed. Notes: When humans got TV, they quit reading. When they got literacy, they quit story-telling. So when they got language, what did they quit? ESP? That’s my theory, which did not make me very highly regarded in grad schools decades ago. But guess what? Now the cutting-edge linguists at last agree! So if linguists can open up to “intersubjectivity”, can economists finally open up to the role of rent about which so many of us are in denial?
