    A Framework for the Emotional Psychology of Group Membership
    Review of Philosophy and Psychology 15 (2): 333-354. 2024.
    The vast literature on negative treatment of outgroups and favoritism toward ingroups provides many local insights but is largely fragmented, lacking an overarching framework that might provide a unified overview and guide conceptual integration. As a result, it remains unclear where different local perspectives conflict, how they may reinforce one another, and where they leave gaps in our knowledge of the phenomena. Our aim is to start constructing a framework to help remedy this situation. We …Read more

    Beyond objectivism: new methods for studying metaethical intuitions
    Philosophical Psychology 34 (1): 125-153. 2021.
    Moral realists often assume that folk intuitions are predominantly realist, and they argue that this places the burden of proof on antirealists. More broadly, appeals to intuition in metaethics typically assume that folk judgments are generally consistent across individuals, such that they are at least predominantly something, if not realist. A substantial body of empirical work on moral objectivism has investigated these assumptions, but findings remain inconclusive due to methodological limita…Read more

    Exploring Generation Z’s Perceptions of Green Homes
    with Bhavya Rathna Kota and Luciana Debs
    Sustainability 14. 2022.
    In recent years, there has been an increase in environmental awareness in the United States, leading to steady growth in environmentally conscious consumerism. Looking specifically at green home marketing, understanding the consumer behavior of the next generation of homebuyers, Generation Z (GenZ), is important for environmental and business reasons. This study surveyed 116 university students to explore the influence of specific barriers and types of motivation (intrinsic, instrumental, and no…Read more

    The Free-Will Intuitions Scale and the question of natural compatibilism
    with Oisín Deery and Jasmine Carey
    Philosophical Psychology 28 (6): 776-801. 2015.
    Standard methods in experimental philosophy have sought to measure folk intuitions using experiments, but certain limitations are inherent in experimental methods. Accordingly, we have designed the Free-Will Intuitions Scale to empirically measure folk intuitions relevant to free-will debates using a different method. This method reveals what folk intuitions are like prior to participants' being put in forced-choice experiments. Our results suggest that a central debate in the experimental philo…Read more

    Defending the Free-Will Intuitions Scale: Reply to Stephen Morris
    with Oisín Deery and Jasmine Carey
    Philosophical Psychology 28 (6): 808-814. 2015.
    In our paper, “The Free-Will Intuitions Scale and the question of natural compatibilism” , we seek to advance empirical debates about free will by measuring the relevant folk intuitions using the scale methodology of psychology, as a supplement to standard experimental methods. Stephen Morris raises a number of concerns about our paper. Here, we respond to Morris's concerns

    The priority of the individual in cultural inheritance
    Behavioral and Brain Sciences 37 (3): 257-258. 2014.
    Smaldino's (2014) proposed extension of the theory of cultural evolution embraces emergent group-level traits. We argue, instead, that group-level traits reduce to the traits of individuals, particularly when it comes to the question of how group-level traits are inherited or transmitted, and that this metaphysical fact is integral to the theory of cultural evolution.

    Group Selection in the Evolution of Religion: Genetic Evolution or Cultural Evolution?
    Journal of Cognition and Culture 15 (3-4): 235-253. 2015.
    In the scientific literature on religious evolution, two competing theories appeal to group selection to explain the relationship between religious belief and altruism, or costly, prosocial behavior. Both theories agree that group selection plays an important role in cultural evolution, affecting psychological traits that individuals acquire through social learning. They disagree, however, about whether group selection has also played a role in genetic evolution, affecting traits that are inheri…Read more

    The Goldberg Exaptation Model: Integrating Adaptation and By-Product Theories of Religion
    Review of Philosophy and Psychology 8 (3): 687-708. 2017.
    The literature on the evolution of religion has been divided by a fundamental debate between adaptation theories, which explain religious traits as products of selection for religion, and byproduct theories, which explain religious traits as products of selection for other, non-religious functions. Recently, however, a new position has emerged in this debate, as an influential new theory based on cultural selection claims to integrate adaptation theories with byproduct theories, yielding a singl…Read more
