You've probably heard of the Diderot Effect in the context of shopping spirals—one new purchase makes everything else look shabby, so you keep buying more. But here's the twist most people miss: this psychological domino effect works just as powerfully in the opposite direction. Use one tiny upgrade to trigger a chain of good habits, and you'll build momentum without needing superhuman willpower. Let's explore how to flip the script and make the Diderot Effect work for you.
What Is the Diderot Effect?
The Diderot Effect is simply the idea that one change invites more of the same. When French philosopher Denis Diderot received a beautiful scarlet dressing gown as a gift, he suddenly felt his other possessions looked shabby by comparison. So he replaced them—one by one—until his entire life felt less comfortable than before. It's the classic 'keeping up with yourself' trap.
But the principle isn't limited to objects. Behaviours work the same way. Tidy one corner of your desk and suddenly the clutter beside it demands attention. Start a short planning habit and the act of doing the work becomes easier because the path is clearer. One action whispers to the next: 'More like me, please.'
The Shopping Spiral Nobody Wants
Most of us know the negative version all too well. You buy one sleek new item—a laptop, a pair of trainers, a statement piece of furniture—and suddenly everything around it looks dated. Before you know it, you're surrounded by half-opened boxes, shopping bags, and a bank balance that's taken a beating. The stress of keeping up with your own purchases replaces the joy you felt at the start.
This consumption cascade happens because our brains crave consistency. Once we've upgraded one element, the mismatch between old and new becomes uncomfortable. We feel compelled to 'complete the set,' even when it drains our resources and leaves us more anxious than satisfied.
Flip It: Build a Positive Habit Chain Instead
Here's the good news: you can harness the exact same psychological force to build good habits. The Diderot Effect doesn't care whether it's pushing you towards more stuff or more structure—it just wants consistency. So give it something productive to chase.
Start with one small, positive change that naturally makes the next good action easier or more appealing. For example:
- Lay out your workout clothes beside your bed, which makes getting up to exercise feel like the next logical step.
- Set up a simple planning spot at your desk, so opening your to-do list automatically leads into tackling the first task.
- Put a water bottle on your desk each morning, which reminds you to hydrate and often triggers other self-care habits.
Each link in the chain should feel like a natural continuation of the one before. The goal isn't perfection—it's momentum. When one habit gently nudges the next, you're not relying on willpower alone. You're riding a wave of your own making.
How to Start Your Own Momentum Chain
Pick your smallest possible starting link—the one you'll actually do today. Make it so simple it feels almost silly. Then notice what it makes easier. Does tidying your workspace make you more likely to plan your day? Does planning your day make you more likely to complete your top task? Follow the thread.
Keep the chain tight. Each step should make the next one closer, easier, or more attractive. Short links build quick momentum, and quick momentum builds confidence. Before long, you'll have a self-sustaining system where one good action naturally flows into the next.
