We are wrong.
In reality, our brains are more like a lazy contestant on a game show, we don't look for the "right" answer; we look for the "easiest" comparison. Enter the Decoy Effect: the psychological glitch that makes you spend more, eat worse, and feel like a genius while doing it.
But once you see the wires behind the curtain, you can stop being the puppet and start pulling the strings on your own habits.
You’re at the movies.
Most people hesitate. Four dollars is a snack; eight dollars is a commitment. You’ll probably go Small.
But then, the theater slides in the Decoy:
Suddenly, the Large isn't "expensive", it’s a steal. For a measly fifty cents, you get twice the popcorn! You walk away with a bucket the size of a trash can, feeling like you’ve outmaneuvered the system.
The theater didn't want you to buy the Medium. They hated the Medium. The Medium only exists to make the Large look like a bargain. This is Asymmetric Dominance, and it’s the reason your "sensible" budget disappears every time you go shopping.
The human brain is actually terrible at valuing things in a vacuum. If I ask you, "What is a high-quality leather jacket worth?" you’ll probably shrug. But if I show you a $500 jacket next to a $450 jacket that looks like it was made from a discarded sofa, you will suddenly "know" that the $500 one is a masterpiece.
We don't judge things by what they are; we judge them by what they are .

If businesses can use this to make us buy more sugar and spend more money, why aren't we using it to trick ourselves into being better humans? Here is how to build your own "Choice Architecture."
Most diets fail because the choice is: Salad (Boring) vs. Pizza (Exciting). The brain hates that trade-off.
To win, you need to introduce a Decoy.
Let’s say you’re craving a greasy burger. Instead of "Burger vs. Salad," make the choice:
By focusing on how much better the home-cooked burger is than the "Decoy" (the gas station sad-wich), you give your brain an easy "win." You aren't "settling" for health; you’re choosing the superior version of the experience.
If you want to save $500 a month, don't compare it to "Spending $500." Compare it to a Worse Savings Plan.
Set up three options for yourself:
Option B is objectively stupid. Why would you save almost the same amount for zero return? But by having Option B there, Option A suddenly looks like a high-value "investment" rather than a sacrifice. You’ve tricked your brain into thinking that saving $500 is a "deal" you can't pass up.
Struggling to start a project? Use the "Shitty First Draft" as a decoy.
If your choices are "Write a Masterpiece" vs. "Watch Netflix," Netflix wins.
But if you add a decoy, "Write 10 minutes of absolute, incoherent gibberish", suddenly, "Writing a decent paragraph" feels achievable and logical. You use the low-quality option to make the medium-quality option look effortless.
The world is constantly trying to nudge you toward the "Large Popcorn" of life. Every subscription service, car dealership, and restaurant menu is designed to make the most expensive option look like the smartest one.
The secret to a better life isn't more willpower; it’s better Comparison Management. Stop being the consumer who picks the "best" of three bad options. Start being the architect who designs the options so that the "best" choice is the one that actually helps you.
Next time you’re stuck on a hard decision, ask yourself: "Am I picking this because it’s good, or because someone just showed me something worse?"
