We allow that a convex cost of ‘reneging’ – the distance between a player's commitment and their actual effort – may enter the players’ subjective utility functions, but this is not part of their material payoffs. We study the endogenous determination of this ‘reneging cost’ in an evolutionary setting. Our main result shows that when each player may observe their partner's reneging cost with a high probability, there is a unique stable state in which all players have the same ‘intermediate’ reneging cost, and the equilibrium effort is a second-best outcome.
