Prejudice, Behavior, & Judgment Lab

About PB&J Lab

Welcome to the Prejudice, Behavior, and Judgment (PB&J) Lab!!

We are a team of Colby students, faculty (Prof. Jin X. Goh), and international collaborators who are passionate about using psychological science to understand human relations and current social issues. As our lab name suggests, we research Prejudice (attitudes and beliefs regarding gender, race, sexual orientations), Behavior (nonverbal and verbal behaviors), and Judgment (judgment and perception of people's personality, emotion, morality, identities).


Using multi-method and interdisciplinary approaches, we seek to understand how people perceive, think about, and interact with those who do not share the same social identities (gender, race, sexual orientation). We are also interested in interpersonal processes such as expressions, detections, and perceptions of personality and emotions.

Here are some big questions we are trying to answer in the PB&J Lab:


  • What predicts coalition vs. conflict between different racial groups?

  • How do history and culture shape racial-gender categorizations?

  • Which factors influence our judgments of political behaviors?
  • Who feels like they belong in various domains and spaces?

  • Why are certain personality traits valued over others?

Lab Values & Philosophy

This lab sits on the land that was the traditional territory of the Wabanaki Confederacy. We acknowledge, recognize, and honor the Tribes who comprise the Wabanaki Confederacy, primarily the tribes of the Maliseet, Mi'kmaq, Passamaquoddy, and Penobscot.

Wabanaki means the People of the Dawn. 


In the PB&J Lab, we value and celebrate diversity and inclusion. We believe diversity and inclusion make our science better. These values are reflected in our research and our team members' identities. All students are welcome to join and participate. We value and respect everyone's gender identity, sexual orientation, race, ethnicity, age, religion, language, national origin, veteran status, disability, mental and physical health, socioeconomic status, political affiliation, and any visible or invisible characteristics.​ Many lab members come from diverse backgrounds (Jin included), and we work to ensure that this lab is a safe and inclusive environment where we can discuss difficult questions and conduct rigorous research. 


Science is hard. Human behaviors are complex, intricate, and irrational. Therefore, in the PB&J Lab, we try our hardest to do the best science we can. We use open science practices (such as pre-registration, open data and materials, high-powered design, mini meta-analysis) whenever possible and/or reasonable. We also participate in large-scale collaborative research network, including the Psychological Science Accelerator. Science is hard, but it is easier and more fun when we collaborate, respect, and work with one another.
