Hahah! An unethical study to quantify the survival value of ethics! Isaac Newton would agree that experiments are a necessity!

An economst’s natural experiment, hehe! oh Adam Smith, when does self interest become greed?

Bioengineer some humans to not be greedy.

Some humans because you can opt out, or you can choose it for your designer baby. Then there is a control and an experimental group.

The mad scientist in me is dying to see whether behaviors with moral connotations (greed) confer an advantage for survival.
