    Leaderboards are powerful motivators. They're also risky. Poorly designed, they create anxiety and toxicity. Done right, they drive healthy engagement.

    Here's how to build leaderboards that work.

    The psychology of competition

    Social comparison is hardwired into humans. We instinctively measure ourselves against peers.

    Leaderboards tap into this. They provide clear feedback on where you stand. But the effect depends on implementation.

    Healthy competition: Motivates effort, celebrates success, creates shared excitement.

    Toxic competition: Creates anxiety, discourages participation, rewards gaming the system.

    The difference is in the details.

    Design principles

    1. Reset periodically

    Permanent leaderboards create permanent losers. Someone stuck at the bottom has no incentive to participate.

    Solution: Use seasons. Reset rankings monthly or quarterly. Everyone starts fresh.

    2. Celebrate multiple metrics

    If you only rank by one metric, you only reward one behavior.

    Solution: Show multiple leaderboards. Prediction accuracy. Total predictions made. Winning streaks. Different people can excel at different things.

    3. Show improvement, not just rank

    Being 50th out of 100 feels bad. Improving 10 spots feels good.

    Solution: Highlight progress. "You moved up 5 spots this week" matters more than raw position.

    4. Make participation the baseline

    If leaderboards only show top performers, everyone else feels excluded.

    Solution: Show everyone their rank, not just the top 10. Celebrate participation milestones.

    5. Avoid shame

    Never publicly highlight poor performers. Never create "worst" lists.

    Solution: Focus communication on top performers and personal improvement.

    6. Create opt-out options

    Some people hate competition. Forcing them onto leaderboards backfires.

    Solution: Let individuals opt out of public rankings while still participating.

    Red flags

    Watch for these signs that your leaderboard is causing problems:

    • People stop participating rather than rank low
    • Complaints about fairness or gaming
    • Decreased collaboration across the team
    • Anxiety or stress mentioned in relation to rankings

    Case study: ExperimentBets

    Here's how we designed our leaderboard system:

    • Seasons reset quarterly, giving everyone fresh starts
    • Multiple metrics show accuracy, participation, and earnings
    • Personal stats are always visible, even if not in top 10
    • No shame mechanics since we never highlight poor performers
    • Celebration-focused with end-of-season awards for top performers

    The takeaway

    Leaderboards can motivate without demoralizing. The key is thoughtful design that celebrates success without punishing struggle.
