What is an example of choice architecture?

The opt-out organ donor: Countries where you're a donor unless you opt out have far higher rates than identical opt-in ones.

Where do you see choice architecture in everyday life?

The opt-out organ donor; Eye-level shelf placement; The default 401(k); The cafeteria fruit; Pre-checked boxes.

Design your environment so the good choice is the default — put the fruit at eye level, auto-enroll in savings, delete the app.

How options are arranged quietly steers what people pick, even when nothing is forbidden. The default and the layout do most of the deciding.

The opt-out organ donor
Countries where you're a donor unless you opt out have far higher rates than identical opt-in ones.
Eye-level shelf placement
Stores put high-margin items where your gaze lands; the layout sells before you choose.
The default 401(k)
Auto-enrolling employees, with opt-out, dramatically raises how many save for retirement.
The cafeteria fruit
Putting fruit first and at eye level nudges healthier picks without banning anything.
Pre-checked boxes
A pre-ticked 'add insurance' rides along because changing the default takes effort most won't spend.

Design your environment so the good choice is the default — put the fruit at eye level, auto-enroll in savings, delete the app.
To help people do something, reduce friction and make it the path of least resistance rather than relying on willpower.
Audit a behavior you want to change by asking "how is my environment voting?" and re-arrange it.

That's just how memory works. Lock choice architecture in with a 5-minute active-recall session — spaced repetition, no signup.
