Trained as a lawyer, cognitive scientist, and philosopher, my research employs the methods of experimental cognitive science and analytic philosophy to address topics in legal theory, many of which are also of practical significance.

For example, I use experiments to study legal interpretation and evaluate what different tools of interpretation tell us about the “ordinary meaning” of legal texts. In other experimental work I examine the ordinary criteria of concepts of legal significance (e.g. reasonableness). This research program reflects the emerging field of “experimental jurisprudence,” an experimental-philosophical approach to legal theory.

Research Areas

Legal Interpretation

Among the most pervasive legal tasks is the interpretation of legal texts. And within interpretation, perhaps the most pervasive inquiry is the search for "ordinary meaning." Interpretation--of constitutions, contracts, deeds, patents, regulations, statutes, treaties, trusts, and wills--regularly includes evaluation of how the text would be understood by ordinary people. A central component of my research involves the experimental study of ordinary meaning in legal interpretive contexts. One set of studies reveals whether dictionaries or corpus linguistics provide reliable evidence about ordinary meaning.

Private Law Theory

Beyond my work on legal interpretation (e.g. of contracts) and concepts (e.g. reasonableness), I also write in private law theory. In Private Enforcement of Privacy Policies, Alexander Stremitzer, Florencia Marotta-Wurgler, and I present an an empirical study of courts' treatment of privacy policies as contracts to inform new doctrinal strategies for the private enforcement of privacy policy violations. I have also written on topics in law and statistics, such as how antidiscrimination law should treat comparatively small discriminatory impacts.

Legal and Moral Theory

I write on topics in moral and legal philosophy such as how theories should confront the imperfect acceptance of rules. In other work I have studied the nature of moral, legal, and philosophical "intuitions," asking whether they are reliable and if professionals - such as ethicists, judges, or philosophers - have expertise in intuition. I address questions like these in theoretical and experimental work.

Legal Concepts

Much of my work uses experimental methods to study concepts, especially ones central to debates in legal philosophy. In How People Judge What Is Reasonable, I report a study finding that the ordinary concept of reasonableness is a "hybrid concept," reflecting both statistical and prescriptive norms: consideration of what is common and what is good. The second half of that project provides a normative analysis regarding whether legal reasonableness standards should reflect this hybrid feature of the ordinary concept. Other experimental projects study concepts including intentional action, consent, causation, motive, contractthe self, and the law itself.

Empirical Legal Studies

In addition to my experimental work, I also pursue collaborations in empirical legal studies. Some of these projects employ traditional methods of empirical legal scholarship, while others make use of recent advances in machine learning and natural language processing. As one example, Elliott Ash and I are creating a machine learning legal dictionary.

The Self and Personal Identity

Which types of change make someone seem like "no longer the same person"? I've found that deteriorations seem more disruptive to identity, compared to similar improvements. My theoretical work asks whether this is an untrustworthy judgment, erroneously affecting our judgment of mental deterioration. More recent experimental work discovers similar judgments about changing non-human entities (e.g. organizations), and suggests that folk teleology drives these judgments.
