It has been argued that naturalizing the mind will result in the elimination of the ontology of folk psychology (e.g. beliefs and desires). This paper draws from a wide range of empirical literature, including from developmental and cross-cultural psychology, in building an argument for a position dubbed restrictive materialism . The position holds that while the ontology of folk psychology is overextended, there is a restricted domain in which the application of the folk ontology remains secure. From the evidence of (...) developmental uniformity and cross-cultural ubiquity of beliefs and desires, it is argued that the ontology (but not the principles) of folk psychology may be incorrigible. Thus, even if radically false as a description of first-order brain processes, beliefs and desires might be an unavoidable second-order brain process. Given that the domain of psychology is how humans think, if the above argument is correct, then beliefs and desires will continue to earn their rightful place in the ontology of any future psychology, in just the same way as any other scientific entity.

The standard philosophical definition of placebos offered by Grünbaum is incompatible with Cartwright’s conception of randomized clinical trials. I offer a modified account of placebos that respects this role and clarifies why many current medical trials fail to warrant the conclusions they are typically seen as yielding. I then consider recent changes to guidelines for reporting medical trials and show that pessimism over parsing out the cause of “unblinding” is premature. Specifically, using a trial of antidepressants, I show how more (...) sophisticated statistical analyses can parse out the source of such effects and serve as an alternative to placebo control.

In recent years the social nature of scientific inquiry has generated considerable interest. We examine the effect of an epistemically impure agent on a community of honest truth seekers. Extending a formal model of network epistemology pioneered by Zollman, we conclude that an intransigently biased agent prevents the community from ever converging to the truth. We explore two solutions to this problem, including a novel procedure for endogenous network formation in which agents choose whom to trust. We contend that our (...) model nicely captures aspects of current problems in medical research and gesture at some morals for medical epistemology more generally. (shrink)

Polarization is a topic of intense interest among social scientists, but there is significant disagreement regarding the character of the phenomenon and little understanding of underlying mechanics. A first problem, we argue, is that polarization appears in the literature as not one concept but many. In the first part of the article, we distinguish nine phenomena that may be considered polarization, with suggestions of appropriate measures for each. In the second part of the article, we apply this analysis to evaluate (...) the types of polarization generated by the three major families of computational models proposing specific mechanisms of opinion polarization.
