Why Infinite Scroll Wins and Your dApp Doesn’t

Variable Reinforcement Theory for builders - learn how variable rewards fuel engagement.

1. Habit Apps – Habitica drops surprise loot when you finish tasks. The user’s intrinsic goal (build a habit) is rewarded by variable perks: digital pets, costumes, bragging rights.

2. Language Learning – Duolingo occasionally triples XP for a lesson. The unpredictability keeps the owl from becoming white noise.

3. E‑commerce Delight – A grocery app throws an unexpected $5 produce credit into loyal shoppers’ carts. Healthier buying behavior, higher retention—mutual win.
   

1. Infinite Scroll – Aza Raskin’s 2006 invention removed the “stop” cue; every swipe is a slot‑pull for novelty. No bottom, no satiety.

2. Social Validation Loops – Like counts drip into your notification tray at random. Sometimes six hearts, sometimes none—so you check ten times an hour.

3. Loot Boxes – 0.5 % chance for a legendary skin; 100 % chance the studio hits quarterly ARR. When real money meets variable ratio, you’ve rebuilt the casino inside Fortnite.

Notice the tech is the same; only intent and context flip it from vitamin to vice.

You always have a choice. Making your choices intentional and visible/known should be natural Web3 behaviour. That's how we can differentiate from Web2 extractive techniques. Here's simple process:

Step 1 – Align the Win.
Write the user’s objective on the whiteboard. If your variable reward nudges them toward that metric (more workouts, better focus), green light. If it only feeds your MAU graph, rethink.

Step 2 – Choose the Schedule.

• Variable Ratio → best for discrete actions: open, post, purchase, collect.

• Variable Interval → best for time‑based beats: daily review, weekly reflection.

Mix in fixed rewards for baseline predictability; use variable sprinkles for delight.

Step 3 – Expose the Odds.
Publish drop rates. Transparency flips the script from manipulation to partnership.

Step 4 – Build Off‑Ramps.
Session timers, fatigue meters, “done for today” nudges. A lever with no exit is a trap.

Step 5 – Measure Regret, Not Just Retention.
Pair dashboards with user interviews. If the verbatim reads, “I lost track of time,” tighten the loop.

Here comes a big question - is a loot box always evil? Zoom out. A teenager in Oslo drops €50 chasing a purple sword—arguably predatory. A gamer in Manila flips that same sword on a resale market and feeds her family. Same mechanic, opposite life outcomes. Tools are neutral; ecosystems decide the ethics. Ask who gains agency and who loses it. 🤔

Dan Koe’s line fits here: Your product is a mirror of your philosophy. If your worldview is “users are resources,” variable reinforcement becomes extraction. If it’s “users are allies,” the same schedule becomes acceleration.

But I'm not saying I'm right. What do you think?

These will give you real-life examples, positive and negative, all built upon theories mentioned above.

• TED Talk – Tristan Harris, 2017: “How a handful of tech companies control billions of minds.” A crash course in attention engineering. (ted.com)

• YouTube – Nir Eyal webinar, 2014: “Hooked: How to Build Habit‑Forming Products.” Walks through variable rewards inside the Hook Model. (YouTube)

• Medium – Tristan Harris, 2016: “How Technology Hijacks People’s Minds.” A magician‑turned‑ethicist dissects dark loops. (Medium)

Variable reinforcement can be like electricity for product builders: wire it right and you light homes; wire it wrong and you zap the neighborhood. (obviously I used to work with a lot of utility companies in the past)

Growth isn’t about adding more electricity - it’s about directing the current toward value. Find your north star, respect the user, and your growth loops will spin long after the token launch hype fades.

Human psychology is truly intriguing and still such an unexplored field that I felt compelled to share the variable reinforcement theory in (hopefully) a digestible format, so more Web3 builders could think about making things more fun for mass users. More theories coming as I read through my past notes and new research.

Let me know what you think and if you need help applying any of the "knowledge" I write about.
Shoot me an email or just DM.

Till next time, let's BUILD BETTER!

BFG

Coming Up Next:

I think in the next one I will finally get to those potential underdog themes and edge ideas that present opportunities for small, fast-moving Web3 teams. I know, I teased it like five times now.

Stay tuned!
