“The experiment involved a “give and take” system, where robots could choose which of their peers to donate to.
As the virtual game unfolded, individual robots learned new donation strategies by copying other robots – to benefit themselves.
The study found that robots would donate to each other within small groups, denying outsiders to improve their own takings.”

But it explains why nationalism and tribalism is basically human rent seeking behavior and cannot be effectively removed by propaganda or legislation.
