Converging to the Lowest Common Denominator in Physical Health
By: Leslie K. John and Michael I. Norton
Abstract
Objective: This research examines how access to information on peer health behaviors affects one's own health behavior. Methods: We report the results of a randomized field experiment in a large corporation in which we introduced walkstations (treadmills attached to desks that enable employees to walk while working), provided employees with feedback on their own and their co-workers' usage, and assessed usage over six months. We report how we determined our sample size, as well as all data exclusions, manipulations, and measures in the study. Results: Walkstation usage declined most when participants were given information on co-workers' usage levels, due to a tendency to converge to the lowest common denominator—their least-active co-workers. Conclusion: This research demonstrates the impact of the lowest common denominator in physical activity: people's activity levels tend to converge to the lowest-performing members of their groups. This research adds to our understanding of the factors that determine when the behavior of others impacts our own behavior for the better—and the worse.
