Embedding Self-Regulated Learning in the Classroom: Evidence from a Teacher Training Program (with Richard Kališ) [policy report]
Our study evaluates the impact of the teacher training program aimed at developing students' self-regulated learning (SRL) skills. Fourteen teachers implemented the intervention with 397 students in Slovakia and the Czech Republic, using a within-teacher design—each teacher taught both treatment and control groups. The intervention group received instruction incorporating SRL principles, while the control group followed standard lessons. Results show that students in the intervention group demonstrated greater ability to plan their learning, justify their preferences, and showed higher internal motivation. The findings suggest that even short-term teacher training can positively influence student learning behaviors.
Regional Norm Inference: A Replication and Attitudinal Variations Across Italy (with Cristina Bicchieri, Marco Faillo and Laura Marcon)
This paper examines how people infer social expectations from information about what others do (empirical norms) and what others approve of (normative norms), and whether these inferences differ for positive versus negative behaviors. Replicating prior work in an Italian sample, we test the robustness of observed asymmetries—where people more readily assume that common positive behaviors are endorsed than vice versa. We also investigate how political conservatism shapes receptivity to norm-related information, exploring whether conservatives’ greater reliance on intuitive reasoning and skepticism toward external evidence reduces their responsiveness to empirical and normative cues.
Do ChatGPT Messages Bridge or Break Communication? Experimental Evidence on Response Rates Across Relationship Types (with Mostafa Goudarzi)
In this project, we evaluate the impact of ChatGPT-edited messages on response rates in communications, examining multiple relationship dimensions between senders and recipients. Using experimental data, we identify an inverted relationship between relational closeness and the effect of ChatGPT. While messages edited with ChatGPT negatively impact response rates among close ties, they significantly improve response rates in more formal or distant relationships. These findings highlight the nuanced role of AI-generated language in interpersonal dynamics and suggest context-dependent effects of using ChatGPT in communication strategies.
Biased benefit and cost estimation in religious signalers (with Martin Lang, Eva Kundtová Klocová, Alexandra Ružičková, and Radim Chvaja) [web]
The costly signaling theory of religion suggests that religious rituals signal group commitment and reveal hidden cooperative intentions. However, it is unclear why non-religious people don't perform these rituals to free-ride on the benefits. Sosis argued that committed members perceive ritual costs as lower, altering their benefit-cost calculations. Our findings, however, show that ardent members see these costs as larger but view them as benefits (e.g., pleasing a deity), which motivates them to perform rituals and signal commitment simultaneously.
Social Norms Expectations in Third-Party Punishment (with Jonathan Stäbler) [WP]
We study whether individuals engage in third-party punishment because they want to enforce social norms. We run an experiment and explicitly measure subjects' beliefs about social norms. We further implement four treatments to exogenously shift norm perceptions and thus identify their causal impact. We find that each of the three norm perceptions has a causal positive impact on punishment on its own. Furthermore, for their joint correlations with punishment, we identify that higher personal norms and empirical expectations are associated with higher punishment decisions, whereas normative expectations are negatively correlated. We conclude that third-party punishment is used for the enforcement of social norms, i.e., beliefs of common behavior, and for the potential creation of new social norms through enforcing the own personal view of appropriateness.
