Friction
Small obstacles dramatically reduce behavior; small enablers dramatically increase it.
What is Friction?
Small obstacles dramatically reduce behavior; small enablers dramatically increase it.
Friction isn't just theory—it's a practical framework for better decisions. This page explains how it works and how to apply it.
Real World Application
To do more of something, reduce friction. To do less, increase friction.
Why This Works
The power of Friction comes from its ability to compress complexity. A good mental model acts like a lens—it brings the important features into focus.
Case Study
Keep your guitar out to play more; delete social apps from your phone to scroll less.
When To Use
This model is most useful when you're stuck. If your current approach isn't working, Friction often reveals the hidden constraint.
Common Mistakes
Over-applying: Not every problem benefits from this model. Match the tool to the situation.
Under-applying: People learn the model but don't practice it. Application takes repetition.
Misunderstanding the principle: Surface-level understanding leads to poor execution. Study the examples.
Ignoring context: The same model works differently in different domains. Adapt accordingly.
Practice Exercises
Identify a current decision you're facing. Write down the assumptions you're making. Challenge each one.
Look at a past failure. Apply Friction retroactively—would it have changed the outcome?
Teach the model to someone else. If you can't explain it simply, you don't understand it well enough.
Set a reminder to apply this model once per week for the next month. Track the results.
Related Models
Friction often pairs well with other Productivity models. Combining frameworks multiplies their power.
