Dave never ceases to amaze me with his detailed and thoughtful posts.  This one is on decision making. 

indigenous peoples tend to make decisions more holistically, rather than biasing their decisions in favour of intellectual knowledge alone. They are more tentative in their judgements and try to allow more time for all knowledge, including that which is subconscious, to be considered and integrated.

They will place great weight on the judgements of those they trust, but ultimately each individual will be trusted (given the authority) and expected (given the responsibility) to make any decision that affects them alone, without having to justify it to others.

When the decision affects others, they will make the decision-making process a collective one, and will allow those who disagree with the decision to opt out of it (provided that does not adversely affect the welfare of others).

I like metaphors that retreat to basic instinct.  Any time we can identify those, and relate to technology enablers, this suggests a winner.  This reflects basic democracy in action. 

The implications for group interactions, and social network trust are real, and need to be understood.
