i think i see a relation between centralization vs decentralization, discussion, aggression, and men and women and patriarchy.
why are men always on top of dominance hierarchies? because they are more aggressive. not because they are more right (being right helps, but is not the reason), but they are more aggressive. [in the simplest case, least thought out case, this is "best fighter wins"]
in a contest, the more aggressive the participants, the greater the cost of contest.
centralized systems will not always be perfect, but they will generally be bigger. this is because...
decentralization always comes with greater total cost.
discussion, which is stems from decentralization, and is a form of a contest, comes with a high cost.
the cost of having a somewhat effective but hyper-aggressive leader is actually lower than a very effective but not aggressive leader.
its almost like entropy?
cost of constraints drives cooperation/redundancy
