A new study led by Dr. Andreas Bayerl from Erasmus School of Economics, Dr. Yaniv Dover from The Hebrew University, and Prof. Hila Riemer and Prof. Danny Shapira from the Ben-Gurion University of the Negev has identified a significant and consistent gender rating gap in online reviews, revealing that women's average ratings are higher than men's across major platforms such as Amazon, Google, IMDb, TripAdvisor, and Yelp.
The research paper titled "Gender rating gap in online reviews" is published in Nature Human Behaviour.
Relying on the analysis of more than 1.2 billion actual online reviews, supplemented by two controlled lab experiments, this research suggests that gender differences in the willingness to share negative feedback drive this gap.
