  A series of examples of computational models is provided, where the model aim
is to interpret numerical results in terms of internal states of agents minds.
Two opposite strategies or research can be distinguished in the literature.
First is to reproduce the richness and complexity of real world as faithfully
as possible, second is to apply simple assumptions and check the results in
depth. As a rule, the results of the latter method agree only qualitatively
with some stylized facts. The price we pay for more detailed predictions within
the former method is that consequences of the rich set of underlying
assumptions remain unchecked. Here we argue that for computational reasons,
complex models with many parameters are less suitable.
