But then again, you know a priori what agents are going to observe and
conceptualize, the vocabulary of the agents is pre-defined and the concept
underlying it was already defined and programmed.
Agents can indeed observe and react but that is not sufficient to say that
they observe and understand emergent effects. Of course, that depends upon
the meaning one ascribes to "emergent effects" or "emergent macro
structures" etc. If micro-macro and macro-micro effects is just a way of
referring to and describing, the dynamics of the simulation (with whatever
language one uses to do it), then I would say that most (if not all)
simulations have "downward
causation", "upward" etc, feedback mechanisms etc. I am not convinced that
the
intention of (2) and (3) below is just that one:
>>>2. The simulation then automatically develops explicit data structures
>>>that capture the emergent macro level structures. (These are not
>>>internal
>>>to agents, but are autonomous from them.)
>>>3. These new data structures then have causal effects on the local agents
>>>and their interactions.
