1. evidential symmetry let's say that propositions P and Q are evidentially symmetrical (I'll write this asp & q) for a subject if his evidence no more supports one than the other. I mean to understand evidence very broadly here to encompass whatever we haveIn Tamar Szabó Gendler & John Hawthorne (eds.), Oxford Studies in Epistemology, Oxford University Press. pp. 161. 2005.

13Science, Ignorance and Human ValuesJournal of Human Values 2 (1): 67-81. 1996.This paper attempts to establish that ignorance is a necessary condition for science to have a purpose, just as it is a precondition for any kind of intentional learning or discovety. The author argues that those who find intrinsic value in science must necessarily attribute positive value to ignorance, for the relationship between the two is symbiotic rather than combative. He presents a number of ways in which scientific ignorance may be positively valued by scientists and non-scientists and l…Read more

5The Psychological Benefits of an Uncertain World: Hope and Optimism in the Face of Existential ThreatFrontiers in Psychology 13. 2022.We examine how prior mental health predicts hopes and how hopes predict subsequent mental health, testing hypotheses in a longitudinal study with an Australian nation-wide adult sample regarding mental health consequences of the COVID-19 outbreak during its initial stage. Quota sampling was used to select a sample representative of the adult Australian population in terms of age groups, gender, and geographical location. Mental health measures were selected to include those with the best psychom…Read more

38Scale construction from a decisional viewpointMinds and Machines 16 (3): 339-364. 2006.Many quantitative scales are constructed using cutoffs on a continuum with scores assigned to the cutoffs. This paper develops a framework for using or constructing such scales from a decision-making standpoint. It addresses questions such as: How many distinct thresholds or cutoffs on a scale (i.e., what levels of granularity) are useful for a rational agent? Where should these thresholds be placed given a rational agent’s preferences and risk-orientation? Do scale score assignments have any be…Read more

346Rationality and indeterminate probabilitiesSynthese 187 (1): 33-48. 2012.We argue that indeterminate probabilities are not only rationally permissible for a Bayesian agent, but they may even be rationally required . Our first argument begins by assuming a version of interpretivism: your mental state is the set of probability and utility functions that rationalize your behavioral dispositions as well as possible. This set may consist of multiple probability functions. Then according to interpretivism, this makes it the case that your credal state is indeterminate. Our…Read more

28How Many Alternatives? Partitions Pose Problems for Predictions and DiagnosesSocial Epistemology 23 (3): 347-360. 2009.This paper focuses on one matter that poses a problem for both human judges and standard probability frameworks, namely the assumption of a unique (privileged) and complete partition of the state-space of possible events. This is tantamount to assuming that we know all possible outcomes or alternatives in advance of making a decision, but it is clear that there are many practical situations in prediction, diagnosis, and decision-making where such partitions are contestable and/or incomplete. The…Read more
