John B. Nezlek

John B. Nezlek is a Professor at SWPS University in Poland, affiliated with the Institute of Psychology and the Center for Climate Action and Social Transformations (4CAST). His work spans multiple campuses including Poznań and Warsaw, where he conducts research at the intersection of social and personality psychology with contemporary societal issues.

Nezlek's research primarily focuses on the psychology of vegetarianism as a social identity, climate change psychology, and the role of values in prosocial behavior. His work frequently employs diary methods and multilevel modeling techniques to examine within-person processes. He has made significant contributions to understanding how dietary choices function as social identities, the psychological consequences of vegetarianism, and the relationship between values and environmental action. His research on emotion regulation in everyday life has provided important insights into how people manage their emotions across different contexts.

Analysis of Nezlek's recent publications reveals a strong emphasis on the intersection of dietary behavior and social psychology, particularly vegetarianism and its social implications. His work increasingly examines climate change distress and how it interacts with religious belief and political orientation. There's also a clear trend toward studying well-being mechanisms, with numerous papers exploring mediators like environmental mastery, basic need satisfaction, and gratitude in the relationship between various psychological constructs and well-being outcomes.

Nezlek leads research within the Center for Climate Action and Social Transformations (4CAST), where his team employs intensive longitudinal methods to study real-time psychological processes. His work on diary methodology has established him as an expert in within-person research designs. Current projects appear to focus on the psychological aspects of climate change adaptation, the social dynamics of dietary choices, and the interplay between religious belief, political orientation, and environmental concern. His research has practical implications for understanding how to promote sustainable behaviors and improve well-being through psychological interventions.
