Hooked
A behavioral product model built around trigger, action, variable reward and investment loops.
Why it matters
Repeated product use can be designed, but the same mechanics can help users or exploit them depending on the problem being solved.
02
Core ideas
What is worth remembering after you close the page
01
Triggers start behavior
External cues can gradually become internal cues when the product repeatedly solves the same need.
02
Reduce action friction
The easier the next useful step is, the more likely behavior is to occur.
03
Investment can increase value
User effort can make a product more useful later by adding data, skill or personalization.
03
Turn it into action
Three things to test today
- 1
Map the current trigger-to-action loop for one product behavior.
- 2
Remove one unnecessary step before the core value appears.
- 3
Check whether the loop serves the user or merely increases usage.
