“…Unfortunately, illuminating as it is, and in spite of Popper s enormous influence in other respects, this metaphor of science as a game and scientific method as a set of conventions had only but an extremely marginal repercussion. 2 To remedy in part this situation, in a series of papers (Zamora-Bonilla 1999, 2002a, 2006a-b, 2007, Ferreira and Zamora-Bonilla 2006 I have been arguing for the applicability of game-theory reasoning to understand some essential aspects of the construction and evolution of scientific knowledge, aspects that have been strongly disputed within that slippery and misty field between philosophy of science and science studies. 3 The basic idea of those papers was to describe the scientific situations from the point of view of scientists themselves, of their epistemic and non-epistemic interests, and to assume that the final state to which their decisions lead must have the property of being a Nash equilibrium, i.e., a combination of decisions so that the choice made by each individual is optimal given the choices of the others (the rationale behind this idea is that, if a situation is not a Nash equilibrium, then at least one agent will realise she can get a better outcome by changing her choice, hence changing the collective state).…”
