Three is more than two: why coalition formation is not easy

In this short version of my inaugural address I describe how people form coalitions. I argue that people behave as if they are already a member of a coalition without realizing that they could also be excluded from the winning coalition. As a consequence people use specific tactics that have proven their success in dyadic interactions. Using examples of research on resources, power, distribution rules, emotions and deception, I show that the implementation of such tactics yield unexpected and potentially disastrous outcomes in triadic settings.
