Bayesian–Nash equilibria in theory of planned behaviour

The theory of planned behaviour studies the decision-making mechanisms of individuals.
We propose the Bayesian–Nash equilibria as one, of many, possible mechanisms of
transforming human intentions in behaviour. This process corresponds to the best strategic
individual decision taking in account the collective response. We show that saturation,
boredom and frustration can lead to splitted strategies, in opposition to no saturation that
leads to a constant strategy.
