Tools from statistical physics have long been used in sociological and economical models. It's no wonder, because statistical physics was devised as a tool for the study of complex systems. For the same reason I don't deem entropy to be a fundamental property of physics, but one of complex systems. As far as I remember from university, the 2nd law of thermodynamics simply arises from the fact, that there are exponentially more unordered than ordered states. Though information itself may be a fundamental physical property. The recent interest in Quantum computers shines new light on the connection between information and Quantum Mechanics. It remains to be seen, how that point of view is compatible with relativity. I hope, that one day someone finds out, that the "time dimension" arises in the macroscopic limit from a graph of discrete causal events.
