Rewards of the hunt with natural stopping points

Let users search for useful or interesting things where the next item is uncertain, mixing what they asked for with occasional discoveries. Build in endings: a daily drop at a set time, 'you're all caught up' markers and session summaries.

Evidence grade C. Limited evidence: few or small studies.Return

Plain label: discovery that knows when to stopAlso known as: feed, infinite scroll, daily drop, discovery feed, curiosity, mystery, rewards of the hunt, personal relevance

How it works

Anticipating an uncertain find holds attention more than a predictable one, which is why feeds and searches pull people back. The same pull lets endless feeds run past what the user intended, so a finishable unit or a scheduled drop keeps the hunt rewarding without regret.

Evidence warning

What the research says

  • Pigeons pressed far more under unpredictable reward schedules than fixed ones, and reward circuits respond most while anticipating a reward.

    Skinner; Knutson (as cited in Hooked Ch.4)

How to build it

Mobile
A daily puzzle or insight that unlocks at a sensible hour, with quiet hours.
Web
Discovery grids that blend saved interests with a few new items and end with 'you're all caught up'.
E-commerce
New-arrival drops on a set day each week.
B2B
An insight card that changes per visit, with a clear 'that's all for today'.

What can go wrong

  • No stopping point.
  • Teasers whose payoff is empty.
  • Late-night drops that disrupt sleep.

Pairs well with

  • A reliable core reward first.
  • Keep users in control with time settings.
