Want to change a habit? Don't use willpower — use friction.

Behavioral scientists have discovered that friction — the small effort required to do something — is one of the most powerful forces shaping your daily choices. Adding just 10 seconds of effort to a bad habit can reduce how often you do it by up to 50%. Removing friction from a good habit has the opposite effect.

Here's how it works in practice: if you want to stop mindless snacking, move the snacks from the counter to a high shelf behind other items. You haven't banned them — you've just added friction. Want to exercise more? Sleep in your workout clothes and put your shoes by the bed. The two-minute rule is friction engineering in disguise: if starting a habit takes less than two minutes of setup, you're far more likely to follow through.

Tech companies already use this against you. Infinite scroll, autoplay, and one-click purchasing all work by removing friction. But you can reverse-engineer the same principle. Log out of social media after each session. Delete apps from your home screen. Use a browser extension that adds a 10-second delay before loading distracting sites. You're not fighting your impulses — you're redesigning the path so the better choice is the easier one.
