Nico Gradwohl is a postdoctoral researcher in Cognition and Consumer Behavior at the Karlsruhe Institute of Technology (KIT). His research focuses on understanding how individuals and groups make economic decisions in uncertain situations. Specifically, he examines how people interpret and process both numerical and non-numerical information in their environment, and how groups come together to make decisions based on these individual experiences. One of his key interests is exploring how these decision-making processes contribute to the spread and persistence of both misinformation and factual information. Ultimately, his goal is to use this understanding to improve how we communicate risks, numbers, and other types of information, as well as how people integrate information when making decisions.

To conduct his research, Nico combines computational modeling and simulations with behavioral experiments, including online group studies, and advanced statistical analysis. Before joining KIT, he worked on the Science X Media project at Charité – Universitätsmedizin in Berlin (2024) and completed a postdoctoral position at the Centre for the Advanced Study of Collective Behaviour at the University of Konstanz (2021-2023). Nico earned his PhD in 2021 from the Graduate School of Decision Sciences at the University of Konstanz.
