Again i was browsing 'Nature' a bit and my eye fell on an interesting paper entitled 'Group decision-making in animals.' They modelled the 'fitness-consequences' for 2 basic decision making principles. Despotism and democracy. As you can see this sort of information could also be useful for us to know. Which social model would actually result in the most favourable decisions for everybody. guess what? The costs were considerably higher for the groupmembers under the despotism model. The democratic decision model was more favourable not because every individual has influence on the decision, but because they tend to produce less extreme decisions.
