Michael conducts his research in partnership with scholars from across the world. Most of the research is conducted through the Behavioral Laboratory at the Yale University School of Management. In the behavioral lab, we use a wide range of research methods including archival data analysis, ethological observations, and psychophysiological assessments in controlled lab and field settings. We use these methods to examine research questions including: 

  • Is subjective or objective social standing a stronger predictor of well-being?

  • How aware are individuals of racial inequality in society?

  • Do signals of wealth inspire greed or generosity?

  • How do elites persuade or manipulate lower status members of society?

  • What emotion processes increase trust and cooperation?

  • Why do allies join social movements?

STUDY MATERIALS: Most of the data, study materials, and pre-registrations for our ongoing research projects are housed at the Open Science Framework. 

SUMMER INTERNSHIP: Our summer internship in micro organizational behavior application for 2019 is closed at this time and will open in the Spring. Read about our 2017 internship HERE.

PROSPECTIVE GRADUATE STUDENTS: Michael is open to accepting graduate students for the PhD program in organizational behavior during Fall 2019. Please keep in mind that as a matter of policy, Michael prefers not to have contact with prospective students regarding the PhD application prior to application review.

Michael will give full consideration to all applications but be sure to list “Michael Kraus” as a potential mentor in your application materials. Please keep in mind that although many students in the psychology program work with our lab we do not accept psychology graduate students and Michael does not review graduate applications to the psychology program at Yale.

Meet the Lab!

Jun Won Park

Jun Won is a doctoral student at the Yale School of Management. A Washingtonian at heart, he enjoys listening to rain sounds while the sun is out. His current research interests are broadly related to the psychology of collective action and social identity, with a focus on allyship in social movements. He received his BA in Psychology from Pomona College before coming to the Yale.


Bennett Callaghan

Bennett Callaghan is a member of the Kraus Lab as well as a member of the Yale Intergroup Relations Lab. His research interests broadly relate to the psychology of social class, both in terms of how it is experienced (on a personal and cultural level) and how it is implicated in collective and inter-group processes. Some research investigates how class influences people’s responses to political messages or candidates. Other research investigates how individuals communicate and perceive signals of social class or social status and how such signals influence other’s behavior. Bennett received his BA in Forensic Psychology, with a minor in English, at John Jay College of Criminal Justice (City University of New York) and spent two years at the University of Illinois at Urbana-Champaign before coming to Yale.

Ginés Navarro-Carillo

I am a doctoral student in the Department of Social Psychology at the Mind, Brain and Behaviour Research Center (University of Granada, Spain). My doctoral thesis project is supported by a grant from the Spanish Ministry of Education, Culture and Sport, within the Education's University Faculty Training programme (FPU). The overall aim of my thesis is to analyse how social class rank and perceived personal economic descent due to the Spanish crisis shape different psychological processes and behaviour. My main personal interests, besides studying the psychosocial consequences of social and economic inequality, are poetry, cinema, comedy and basketball.

Monique Baca

Monique is an intern this summer and recently received her Bachelor’s degree from University of Colorado Boulder. Her BA is in Psychology and Economics with the degree designation summa cum laude. As a first-generation student Monique cares deeply about economic inequality and the lack of social mobility in the United States. Her research interests also include the psychology of judgment and decision making, particularly financial decision making and saving behaviors. In her free time, Monique loves to visit with family especially her two nephews Marcus and Eric.

Nathaniel Marino

Nathaniel Marino is a summer intern and a second years Master’s student at Rutgers University in Camden, New Jersey. Nathaniel’s research interests span across social/personality psychology from personality traits and personality assessment to social group dynamics and social class. Nathaniel is particularly interested in the study of morals, values, beliefs, and ideologies. Specifically how belief systems and ideologies shape our social structures and the morals and values individuals use to navigate these complex structures. When not grinding away at the never ending tasks of academic work, Nathaniel prefers spending every minute with his wife playing video-games, table tennis, and practicing card tricks.
