Change the default
Level: Beginner · Free — no account needed to read
Make the option you want the one that happens if you do nothing: water on the desk, lunch packed, a blank page when the laptop opens.
Why it may help
People tend to stick with defaults. Setting your own means good choices happen without a decision.
When to use it
- Daily moments that repeat
- Choices made when tired or rushed
- Digital settings
How to apply it
- Pick a moment that happens daily.
- Notice what happens by default.
- Change the default to the option you want.
An example
Kiran packs lunch the night before, so the default is the meal he chose calmly.
The common mistake
Setting a default so strict you override it every time.
Practise it
Change one default in your home or phone today.
What the evidence says
Evidence mixed: Some studies support it and others do not, or early findings shrank when researchers tried to repeat them. The lesson explains both sides.
Defaults can have large effects in some settings, but the average effect of nudges is debated once unpublished results are considered. Test it on yourself.

Problems it helps with
- “I remember, but I don’t start.” — You know it’s time. You even think about it. And then you do something else.
