Yes, they do!
Those who live in like minded social group, have advantage of distributed cognition. We Indians call it वर्ण & जाती. Unfortunately, such natural advantage of superior group decisions are sacrificed by caste-ism and various other -isms. Modern education brainwashed us to believe that वर्ण & जाती are curse upon us. In reality, they actually protected us against so many incursions we faced in last 1000 years. Now since we hate them, we are unknowingly inviting collapse. 🙁
Learn from nature:
The society you live in can shape the complexity of your brain—and it does so differently for social insects than for humans and other vertebrate animals.
A new comparative study of social and solitary wasp species suggests that as social behavior evolved, the brain regions for central cognitive processing in social insect species shrank. This is the opposite of the pattern of brain increases with sociality that has been documented for several kinds of vertebrate animals including mammals, birds and fish.
“By relying on group mates, insect colony members may afford to make less individual brain investment. We call this the distributed cognition hypothesis,” said Sean O’Donnell, PhD, a professor in the Drexel University College of Arts and Sciences who led the study published today in Proceedings of the Royal Society B.
