Hi Dave, I'm well aware that Nash ultimately rejected the too simplistic versions of the theory, and I firmly reject simplistication too. (Nash's problems are well documented.) All I'm doing is separating the poison from the potion, saving the baby from the bathwater.
The poison is the SOMist "objective, tyrrany of numbers" and "me, the subject" that gave us that crass style of economics branded "autistic". With a MoQish view of values and patterns of human behaviour the same game-theory model of anticipation of moves and interests is rational behaviour, prefectly consistent and useful. In fact I'd go further - it will prove essential if we are to have models that defend MoQish values from SOMist freeloaders and other greedy reductionists.
