ABSTRACT
This part conclusion presents an overview of the key concepts discussed in the preceding chapters. It demonstrates the heuristic relevance by analysing three case studies. Each of the studies focused on a condition of felicity (empiricity, self-fulfilment and conventional compatibility). The general idea is not to define performativity in so rigorous a sense that it would simply be impossible to identify it. There is no such thing as perfect performativity, bringing together all the underlined conditions. Each time, there is a progressive adjustment, more or less powerful, between the theoretical and the real. The part points out these frictions, where performativity fails, where the theory adapts to a reality that resists it: the theory of rationality must become empirical to allow the establishment of policies of rationalisation, the BSM model had to adapt to real financial movements, economists had to set up matching systems in accordance with the social representations of the organ.
