    A Bayesian Framework for Knowledge Attribution: Evidence From Semantic Integration.Derek Powell, Zachary Horne, Ángel Pinillos & Keith Holyoak - 2015 - Cognition 139:92-104.
    We propose a Bayesian framework for the attribution of knowledge, and apply this framework to generate novel predictions about knowledge attribution for different types of “Gettier cases”, in which an agent is led to a justified true belief yet has made erroneous assumptions. We tested these predictions using a paradigm based on semantic integration. We coded the frequencies with which participants falsely recalled the word “thought” as “knew” (or a near synonym), yielding an implicit measure of conceptual activation. Our experiments (...)

    A Single Counterexample Leads to Moral Belief Revision.Zachary Horne, Derek Powell & John Hummel - 2015 - Cognitive Science 39 (8):1950-1964.
    What kind of evidence will lead people to revise their moral beliefs? Moral beliefs are often strongly held convictions, and existing research has shown that morality is rooted in emotion and socialization rather than deliberative reasoning. In addition, more general issues—such as confirmation bias—further impede coherent belief revision. Here, we explored a unique means for inducing belief revision. In two experiments, participants considered a moral dilemma in which an overwhelming majority of people judged that it was inappropriate to take action (...)

    Belief Updating in Moral Dilemmas.Zachary Horne, Derek Powell & Joseph Spino - 2013 - Review of Philosophy and Psychology 4 (4):705-714.
    Moral psychologists have shown that people’s past moral experiences can affect their subsequent moral decisions. One prominent finding in this line of research is that when people make a judgment about the Trolley dilemma after considering the Footbridge dilemma, they are significantly less likely to decide it is acceptable to redirect a train to save five people. Additionally, this ordering effect is asymmetrical, as making a judgment about the Trolley dilemma has little to no effect on people’s judgments about the (...)
