Do we really need a knowledge-based decision theory?

Abstract: The paper investigates what type of motivation can be given for adopting a knowledge-based decision theory (hereafter, KBDT). KBDT seems to have several advantages over competing theories of rationality. It is commonly argued that this theory would naturally fit with the intuitive idea that being rational is doing what we take to be best given what we know, an idea often supported by appeal to ordinary folk appraisals. Moreover, KBDT seems to strike a perfect balance between the problematic extremes of subject… Show more

“…Finally, zooming out, one might wonder how Flexible Fallibilism compares to a Bayesian view, according to which our (rational) credences, not our knowledge, play the central epistemic role in decision theory. While some have argued that knowledgebased decision theory has some advantages over Bayesian decision theory (see, e.g., Greco, 2013) others have been skeptical (see, e.g., Schiffer, 2007, andFassio &Gao, 2021). I think this is a worthwhile topic for future research (Heil, MS) but beyond the scope of this paper.…”

“…Fassio and Gao (2021) have recently raised various objections against knowledge-based decision theory (and perspectivism more generally). While I will solely be concerned with the challenge from high stakes in this paper, I briefly want to comment on one of the worries they raise: Gao and Fassio conceive of KPR and knowledge-based decision theory as competing views that are differently motivated and offer conflicting recommendations.…”
