%0 Journal Article %T Representing vague opinion %A Daniel J. McKaughan %A John M. Drake %J Principia : an International Journal of Epistemology %D 2012 %I Universidade Federal de Santa Catarina, Brasil %X Current supervaluation models of opinion, notably van FraassenĄ¯s (1984; 1989; 1990; 1998; 2005; 2006) use of intervals to characterize vague opinion, capture nuances of ordinary reflection which are overlooked by classic measure theoretic models of subjective probability. However, after briefly explaining van FraassenĄ¯s approach, we present two limitations in his current framework which provide clear empirical reasons for seeking a refinement. Any empirically adequate account of our actual judgments must reckon with the fact that these are typically neither uniform through the range of outcomes we take to be serious possibilities nor abrupt at the edges. %K Belief %K models of opinion %K subjective probability %K supervaluation %K uncertainty %K van Fraassen %K vagueness. %U http://www.periodicos.ufsc.br/index.php/principia/article/view/1808-1711.2012v16n2p341/24104
