How humans make sense of truth, identity, and information in digitally mediated worlds.

The Computational Social Psychology (CSP) Lab, directed by Dr. Almog Simchon at the Department of Psychology at Ben-Gurion University of the Negev, investigates how people form beliefs, interpret information, and engage with political discourse in the digital age. We study the psychological processes that shape how people reason about evidence, whom they trust, and how political discourse evolves. This includes the dynamics of polarization, misinformation, and the growing influence of generative AI on public communication. Our approach combines behavioral experiments with computational methods, including large-scale text analysis and machine learning.

Research

Misinformation & Trust

Why do people believe things that are not true? We examine the cognitive and social factors that shape how people evaluate information, why misinformation spreads, and when individuals trust or reject what they encounter online. Our work develops and tests interventions, particularly psychological inoculation, using cognitive modeling to disentangle people's ability to tell true from false information from their general tendency to accept or reject claims.

Political Psychology & Polarization

How do political attitudes form and shift in digital environments? We study the dynamics of polarization, partisan conflict, and political communication by combining behavioral experiments with large-scale computational analysis of political speech, from social media posts to parliamentary discourse. Our work examines how the language politicians use both reflects and shapes democratic norms.

Cognition & Epistemic Styles

People differ in how they process and evaluate information. We study how individual differences in thinking styles, intellectual humility, and epistemic orientations relate to belief formation, susceptibility to misinformation, and political attitudes, with particular attention to how these tendencies play out in digitally mediated contexts.

Language, Discourse & AI

Language provides a window into beliefs and psychological processes that scales. We use computational text analysis, from dictionary-based approaches to neural embeddings, to study how people express beliefs, construct narratives, and engage with political discourse. A growing part of our work examines how generative AI is transforming persuasion, public communication, and information ecosystems.
