I disagree on two points.
a. Historically tribes decide by reaching a consensus amongst individual prominent members (chieftains, warriors, priests etc.). Each individual weighed the pros and cons and came to a decision. When some sort of consensus (I am not claiming that they were democratic or anything like that) was reached, the tribe went forward.
