In this new pre-print, I argue that we can represent normative positions about adjudication and conceptual stances on legal validity as Venn diagrams.

I just posted a new pre-print where I argue that dual character concepts are something new and interesting in legal philosophy and beyond and that they can't be reduced to ambiguity, prototypes, or metalinguistic negotiations. Comments are very welcome! papers.ssrn.com/sol3/papers....

Now out @ Journal of Research in Personality (free until June): authors.elsevier.com/a/1k%7EqWL4L... We found evidence that trait empathy correlates with purposivism in rule violation judgments. Also: most people share a single concept that seems to have a dual character structure.

Now the #ExperimentalPhilosophy Society session! @almeida2808.bsky.social presented #xJur data with @lawstuff.bsky.social and Ivar Hannikainen: "Trait #Empathy Predicts Purposivist Rule Application" Results in image #altText #openAccess preprint: dx.doi.org/10.2139/ssrn... #xPhi #law #textualism
Two samples of participants (N≅500) who responded to 20 to 40 cases indicated that most people had both textualist and purposivist intuitions (about rules or "laws" like "no shooting animals" and "no smartphones in the classroom").More data indicating that empathy correlated positively with purposive interpretations and negatively with textualist interpretations.Other individual difference constructs that predicted variance in how people apply rules: action aversion, outcome aversion, control aversion, and some Big 5 personality constructs.Implications
• People seem to share a single concept of rule that has a dual character in nature. This goes against contemporary worries in jurisprudence that propose purely interpersonal explanations of disagreement in legal interpretation. It also bolds well with recent accounts of philosophical problems, specially Knobe's (forthcoming)
• Obama appears to have been right: individual differences in the
"breadth of one's empathy" do indeed matter in the application of rules, but much less than whether the rule's text was violated.

Blueksy! I will be recruiting a PhD student and a lab manager in the Fall of 2025. The lab will study rules and curiosity from a moral psychology lens—exploring how we judge rule-breakers, reason about rules, and what sparks our curiosity in the moral domain.

Why do we find opposing intuitions about philosophical questions? I argue that recent results suggest a new picture: - It’s mostly NOT about different people having different intuitions - It’s about individual people having CONFLICTING INTUITIONS philpapers.org/archive/JOSC...
