The Power of Prior Activity and Group Size in Digital Health Leaderboards | HackerNoon
Briefly

The study examines how leaderboards influence healthful physical activity, revealing that their effects can vary significantly. Factors such as competition intensity and the number of participants on a leaderboard play crucial roles in shaping user engagement and motivation. The research highlights the complexities of how social influences and prior activity levels interact, suggesting that while leaderboards can enhance physical activity, their effectiveness may be inconsistent across individuals, pointing to the importance of understanding these dynamics for better health promotion strategies.
The contradictory effects of competition and social influence not only make the direction of the average effect uncertain, but also suggest substantial heterogeneity in leaderboard effects.
As leaderboards grow, the number of active participants affects the dynamics, potentially heightening competition and accountability among users which can encourage increased physical activity.
