Less is better in separate evaluations versus more is better in joint evaluations: Mostly successful close replication and extension of Hsee
A preregistered close replication and extension of three of Hsee's 1998 studies, with 403 participants recruited and 400 analysed in the dinnerware study. It found support for less-is-better in all three studies and weaker support for more-is-better. In the dinnerware study, separate evaluation gave 33.70 dollars for the 24-piece set and 23.96 for the 40-piece set. Joint evaluation gave 30.35 and 31.67, a difference in the predicted direction that was not statistically significant.
