It appears I'm less rational than I thought. I suppose another way to rephrase that would be that to draw the outline of VNM-rational decisions only up to preferences that are meaningfully resolvable(and TORTURE vs SPECK does not appear to be to me at least) with a heuristic of how to resolve them clearer given intereaction with unresolveable areas. I would still be making a choice, albeit one with the goal of expanding rational decisionmaking to the utmost possible(it would be rational to be as rational as permissable). That seems pretty cheap though, reeking of 'explaining everything'. Worse, one interpretation of this dilemma would be that you have to resolve your preferences and that 'middle' is excluded, in which case it is a hard problem to which case I can likely offer no further suggestion.
