Description
In this paper, we study how the decoy effect, a well-established context effect, impacts the effectiveness of personalization systems. By conducting a controlled experiment and using a real-world movie recommendation system, we find different behavioral effects in personalized and non-personalized settings. Including a decoy item in a set of recommended items negatively impacts the effectiveness of the personalized recommendations, while it does not hurt the efficacy of a non-personalized one.
