Understanding complex physical systems requires knowledge of the interactions among their constituents, in order to be able to predict emergent behaviors (i.e., of the system as a whole). In the last few years, the same approach is being applied to the study of complex social systems, in an effort to gain insight on their behavior from a viewpoint that complements the traditional social sciences one. This kind of research involves a sensible combination of experimentation, data analysis and (agent-based) modeling. In this talk I will focus on the experimentation and data analysis aspects of this new computational social science, by presenting examples of work carried out in my group that make clear the influence of informational and social contexts on the interaction. In particular, I will study dynamic social networks, including the possibility of having a fake reputation; hierarchical social systems, where a comparison with non-human primates can be made, and classification of individual behaviors for later use in modeling and simulation. In this latter case, I will show how promising advances can be made towards a theory by identifying consistent behavior across social dilemmas.
