Impulse-Proof Your Shopping: 8 Psychology Hacks Retailers Wish You Didn't Know

4. The Scarcity Principle

The scarcity principle is a powerful psychological trigger that retailers exploit to drive impulse purchases. By creating a sense of urgency—through limited-time offers or low-stock warnings—retailers make products seem more desirable. This taps into the fear of missing out (FOMO), compelling you to buy now rather than risk losing out. Understanding this tactic can help you pause and assess whether a purchase is truly necessary or if you’re being swayed by artificial scarcity.
