I haven't read the papers all the way through, but on first blush, I don't see them as contradictory. Either could be correct. A leader - whether bird or person - could act first due to internal traits (inclination, ability, imagination) or external influence. The first implies that the leader

Vladimyr - A leader in a cycling peloton is such a temporary phenomenon that one has to be very careful how the term it is used. But in the bird flock the leader seems to be part of a social dynamic which might not actual exist but in the minds of the writers? I agree

But by your own definition, an emergent property requires correlated feedback in the system supression is as likely to emerge as leadership, and thus we revert to the question in earlier conversations about the value systems of the observer fabricating the label of emergent or not. Right?

No, it's a good question, Tory. I said I wasn't sure about the label emergent being applied to suppression, and I'm not. Thinking about it more, it's a good idea to clarify the terminology. Let's see ... a single act of suppression is feedback that helps to preserve the emergent feature of a

Correlated feedback? The example given is that of a pack of dogs chasing a rabbit and keeping it running in a straight line. The straight line is the emergent property. A similar example is a thermostat -- or a bunch of thermostats distributed around an area. (If you like they can control
