Reproducing the 1972 study in a field environment on humans would take too long, but I'm confident that if you had a similar utopian tribe of 60 men and 60 women, the experiment would have to be terminated in less than a year due to whatever mularkey broke out. Scale that up and you have pure Venezuelan chaos on your hands.
