What We Study
|
The central theme motivating our research is the desire to understand the way people think and reach decisions, as well as how to improve these processes to result in better outcomes for society. We are especially interested in human judgment processes as they intersect with the law. We approach these questions with different methods, such as descriptive studies that yield foundational information about phenomena that precedes explanatory experimental work, experimental methods that can yield causal inferences, and integrative syntheses across methods and sources. We study rich, real-world behaviors, embrace open science practices, and weave together theories and methods from the clinical, social, and cognitive traditions of psychological science.
Our work on these topics is organized by three overlapping categories:

Expert Judgment |
In much of our work, we are interested in expert judgment especially as it intersects with the law, such as identifying systematic bias in how forensic psychologists and forensic scientists reach conclusions about cases, problems in how judges make decisions about evidence admissibility, and understanding how policymakers rely on evidence to create policy.

Public Policy Implications

We are explicitly interested in the public policy implications of much of our work, such as how expert judgment processes can be structured to reduce systematic bias and error, how to improve judicial and jury decision making, and how policymakers can harness psychological science about how people behave to craft effective policy.
