for the most part we can look at sentinel island. It has only been molested by a ‘handful’ of people and for all intents and purposes the inhabitants seem to be surviving in harmony with their tribe/space.

or were you talking about repeatedly tossing packs of kids and teens onto islands and writing down what happens. for science. I’d be willing to partake in the test if i wasn’t aged out, if I’m being honest, id like to see where the breakdown happens and/or strengthening of a team begins, and nothing beats a 1st person view.
