WHY WE BUY: THE PSYCHOLOGY OF INCENTIVIZATION

Summary from the TLDR Founders newsletter

You're at a gas station planning to spend $30 on fuel when you spot a sign offering a $10 gift card if you spend $45. Next thing you know, you're filling the tank completely and feeling like you won. B.F. Skinner discovered why we fall for this when he gave rats a lever that sometimes dispensed food - the unpredictable rewards made them press it obsessively because dopamine spikes at anticipation, not just the reward itself. Sephora tosses in free samples knowing you'll come back for full sizes, Asana randomly shows unicorns flying across your screen when you complete tasks, and smart marketers reveal surprise bonuses mid-launch to tip fence-sitters into buying. The right incentive at the right moment turns "maybe" into "yes" and keeps people coming back for more.
