In normal problems, these two principles of rational choice will yield identical policies; but on some Newcomblike problems they may yield different policies. Updateless decision theories refuse bad bargains in the Ultimatum Game, resist simple forms of blackmail, and are Counterfactually Muggable. Their fair problem class corresponds to "cases where my payoff depends on my behavior given any kind of sense input", where an updateful TDT would have a fair problem class only of "cases where my payoff only depended on my behavior given the sense inputs I actually got".
