Some questions prompt an intuitive response. When we ask, “How much should I donate?”, our first response might be something like, “whatever feels right.” Of course, we can step back and reflect on this feeling. “Must I donate that much?” “Must I donate anything?” This reflection can change our initial impulse. “Upon reflection, I can give much more.” Intuition and reflection also feature in philosophy and science.[i]
My research employs both empirical and philosophical tools to clarify the nature and normativity of reflective reasoning (Byrd, 2022; Cullen & Byrd, in prep.), philosophical decision-making (e.g., Byrd & Conway, 2019; Byrd & Białek, 2021; Byrd, under review), implicit bias (Byrd, 2019), technology (Byrd, 2020), and their intersections (Byrd, in prep.). This has implications not only for theory, but also education and democracy.
Here is a selection of my research questions:
- How are our evaluations of arguments and evidence biased?
- How does our sense of identity bias our reasoning?
- How do our biases relate to our moral, political, religious, and other philosophical tendencies?
- How do our biases impact ours and others’ well-being?
- How can we improve each others’ reasoning, decision-making, and well-being?
- How can technology help (or hinder) these improvements?
Bounded Reflectivism: The Nature & Normativity Of Reflective Reasoning
One innovation of my recent research is an algorithmic model of intuitive and reflective reasoning (Figure 1). The model captures the ways in which reflection can both help and hinder our reasoning—e.g., reflection can lead to equilibrium, but it can also lead to polarization.[ii] The key is that reflection can be bound by ‘epistemic identity’—identities that involve particular beliefs such as religious and political identities. When we feel like our epistemic identity is threatened, we can reflectively defend its beliefs rather than dispassionately submit to the best arguments and evidence. The solution, according to the bounded reflectivist model, is not to suppress epistemic identity but embrace it—e.g., shared, superordinate epistemic identities (Byrd, 2022).
Some data already align with bounded reflectivism: Sometimes reflective reasoners converge (Byrd & Conway, 2019), but sometimes reflective reasoners diverge (Byrd, in prep.). With time and funding, the tools of philosophy and cognitive science can elaborate descriptive and normative upshots of bounded reflectivism to improve not only our theories (Byrd & Sytsma, in prep.), but our understanding of high-stakes, real-world reasoning—e.g., negative rumination (Byrd, 2020), implicit bias (Byrd, 2019), deliberative democracy (Byrd, 2022).
Psychology of epistemic identity. In additions to models, experiments can test the effect of epistemic identity on reasoning. There is already some evidence for such an effect: Uhlmann, Pizarro, and Tannenbaum’s (2009) found that cuing patriotism (vs. multiculturalism) had an impact on judgments about moral dilemmas involving foreigners. I propose testing how subordinate (vs. superordinate) epistemic identities such as political party membership (vs. human species membership) may affect reasoning. I also propose testing how this effect interacts with reflection. If reflection can be bound to identity, then it could enhance identity’s effects on reasoning.
Mediators of epistemic identity. The link between reflection and certain beliefs may vary across cultures, levels of education, etc. (Byrd, 2022).[iii] This raises the question of how cultural and other factors might feature in the bounded reflectivist model of reflection. For instance, the effect of reflection on philosophical judgments might be mediated by nationalist (vs. globalist) identity and collectivist (vs. individualist) identity. Another possibility is that unreflective reasoning simply mirrors the predominant norms of agents’ societies. On this possibility, reflective reasoning involves, among other things, considering counter-cultural norms. This can explain why less reflective responding predicts theism and more reflective responding predicts atheism in predominantly theist countries like the US, but not in predominantly atheist countries.
Advancing Philosophy & Science
Improving scientific tools can advance scholarship.[iv] For instance, improved reflection tests reveals how theories and measurements must be modified (e.g., Byrd & Conway, 2019; Byrd, revision requested). So my colleagues and I are investigating ways to further improve measures (Byrd, Joseph, Gongora, & Sirota, in prep.), clarify theory (e.g., Biebel & Byrd, under review; Byrd & Bialek, 2021; Schwenkler, Byrd, Lambert, & Taylor, 2021), and share resources with under-resourced, underrepresented colleagues.
