Professor Jean-Robert Tyran (University of Vienna) with a Lecture at the Faculty of Economic Sciences

Professor Jean-Robert Tyran (University of Vienna) will visit the Faculty of Economic Sciences to deliver a lecture. The presentation will be part of a seminar series dedicated to microeconomics, coordinated by Professor Łukasz Grzybowski (Department of Microeconomics). The speaker will present his study titled „Sorting Fact from Fiction when Reasoning is Motivated” (co-authors: Edoardo Cefalà, Melis Kartal, Sylvia Kritzinger).

(More information about the researcher is available on the following website: https://homepage.univie.ac.at/jean-robert.tyran/short-bio.html)

We invite you to attend the seminar on April 14, 2025, at 15:30. It will be held in Room B102 (Faculty of Economic Sciences). Additionally, you are invited to participate in a lunch with the speaker at 13:30. We encourage you to take part, as it will provide an opportunity to meet, discuss, and gain valuable insights.

If you are unable to attend in person, there is an option to participate remotely via the Zoom platform.

Below, we present an abstract of the presentation.

How is sorting fact from fiction and updating after fact-checking shaped by motivated reasoning, cognitive ability, and overconfidence? We present subjects in an online experiment with news items on immigration, inequality, climate change and science that (to the best of our knowledge) are true or false. As predicted by our model, we find that motivated reasoning reduces acknowledging "inconvenient truths" (i.e., news that are counter to one's identity), while cognitive ability promotes it. Motivated reasoning and overconfidence limit updating after fact checking (i.e. subjects receive informative but noisy signals about the veracity of the news), cognitive ability promotes updating. Surprisingly, higher cognitive ability is negatively related to accuracy in news discernment and updating in news on science and (to a lesser degree) on climate change. The reason seems to be that those with higher cognitive ability are more motivated to believe that anti-science and anti-climate change news are false.
