In the past, these two approaches have been mainly in conflict with each other. We can find examples of failure and success on both sides:
 
 

unsuccessful attempt: 1) Zero-sum game theory in international relations; e.g. Vietnam in 1960s successful attempt: 2) Doyne Farmer et al working in anti-nuclear movement while at Santa Fe Institute.

successful attempt: 1) S. Heim's convincing portrait of von Neumann's mistrustful views influencing game theory  unsuccessful attempt: 2) Psychoanalytic interpretations of SFI simulations

Recently there have been more optimistic examples which suggest possibilities for collaboration:
 

1) Axelrod's Evolution of cooperation, tit-for-tat in iterated prisoner's dilemma. 2) Gottfried Mayer-Kress et al: simulations show failure of Reagan's "Starwars" defense system (on Los Alamos supercomputers!).

1) ACENet: flexible economic networks 2) Applications to indigenous knowledge systems (eg African Fractals, Native American Biocomplexity)
