  Despite these criticisms, many authors over the intervening decades, such as Robert Sugden (1986/2004, 2011) and Ken Binmore and Larry Samuelson (2006), have argued that a satisfactory theory of equilibrium selection requires something like Lewis’s notion of salience. Note also that, even if the foregoing criticisms are legitimate, they do not impugn Lewis’s analysis of what conventions are. They only show that Lewis has not offered a complete theory of how conventions are chosen, how they evolve, and how they sustain themselves.
