Hyperbolic Discounting
We prefer immediate rewards to larger future rewards, and this preference intensifies as rewards become more immediate.
Hyperbolic discounting is a time-inconsistent model of delay discounting. The term comes from the mathematical hyperbolic function. Unlike exponential discounting (the rational standard), hyperbolic discounting means that discount rates are much higher for near-term delays than for far-term delays. People will reliably choose $50 today over $100 next year, but also reliably choose $100 in two years over $50 in one year — an inconsistency that exponential models cannot explain.
What it looks like in the wild.
- Everyday life Marshmallow Test Children who resist immediate marshmallow for two later show better life outcomes — hyperbolic discounting is the impulse being overcome.
- Everyday life Retirement Saving People perpetually delay retirement savings because the future benefit feels heavily discounted relative to present consumption.

Biases are not only private errors. They are design targets — patterns deliberately engineered into interfaces because they reliably work.
- E-commerce Instant Gratification Delivery Same-day and next-day delivery options exploit hyperbolic discounting by making the immediacy premium feel worth paying for items that could wait weeks.
Recognising a definition is not the same skill as spotting it.
Two scenarios from the app, with distractors drawn from the same family of biases — which is what makes them hard.
Maria decides to skip her 401(k) contribution this month to buy a new video game, even though she knows the retirement savings will be worth much more later.
Leo is saving for a car repair, but when a limited-edition sneaker drops, he spends the saved money to buy it immediately.
Biases rarely arrive alone.
