Hypnosis

[Angrboda]

I suspect an early tribe that was able to organize and be more 'ant-like' in their behavior would have an advantage of a tribe behaving as individuals?  So the ability to allow others to control you via suggestion maybe rose up through natural selection?

This only works as an assumption if the environment is stable and repetitive. Under such circumstances, such behavior can capitalize on the consistency in the environment. However if the environment is unstable and subject to change, the lack of individualism leads to opportunity costs and losses due to an inability to flexibly respond to changes in the environment. The ideal human is therefore a mixture of ant-like and individualistic behaviors. What the most profitable mix of such behaviors is will vary depending on the environment.
