How a Bad Option Can Manipulate Your Choice
Why do we feel more strongly about one option after a third one is added?
Imagine you’re buying popcorn at a movie theater.
The prices are:
Small — $4
Medium — $7
Large — $7.50
Suddenly, the large looks like an obvious bargain.
But notice what the medium option is doing.
Very few people may actually want it.
Its real purpose is to make the large look much better.
This is called the decoy effect.
A decoy is an option that is intentionally made less attractive than another choice, so that one particular option feels like the smarter deal.
Without the medium, you might compare:
Small for $4 vs. Large for $7.50
and decide the large is too expensive.
But once the $7 medium appears, the large suddenly feels irresistible:
“For only 50 cents more, I get so much more.”
Nothing about the large changed.
Only the comparison changed.
Businesses use this with:
Subscriptions.
Coffee sizes.
Storage plans.
Restaurant meals.
Streaming packages.
The lesson
When one option suddenly looks “obviously better,” ask:
“Would I still choose this if the other option disappeared?”
Sometimes the best-looking choice isn’t actually better.
It only looks better because a carefully designed decoy is standing next to it.
