A store marks a jacket at $200, then ‘discounts’ it to $120. You feel like you’re saving $80. But if it was always $120, you’d think it’s expensive. The $200 anchor changed your perception.
The Original Discovery
Tversky and Kahneman’s famous studies in the 1970s. They asked people ‘Is the percentage of African nations in the UN higher or lower than 65%?’ Then asked them to estimate the actual percentage. The 65% (random) number anchored all estimates—people who saw 10% estimated much lower, those who saw 65% estimated higher.
How It Works in Real Life
The Anchoring Effect isn’t a rare phenomenon—it’s everywhere once you start looking:
- In salary negotiations, whoever mentions the first number wins. If you say $100K and they say $80K, you’ll likely end up closer to $90K. If you stay silent and they anchor at $70K, the final is much lower.
- You see a house listed at $500K. When it drops to $450K, it feels like a deal. If it was always listed at $450K, the same price feels overpriced. The anchor changed perception of value.
- A wine is described as from a ‘prestigious year’ before tasting. People rate it higher than the identical wine described as from a ‘typical year.’ The anchor (prestigious) changed perception of taste.
Why This Matters to You
Anchoring Effect is why negotiations start with the highest or lowest number first. In salary talks, in real estate, in any negotiation, the first number mentioned disproportionately influences the outcome. It’s also why prices are anchored with ‘original prices’ or ‘competitor prices’—the anchor makes everything else seem reasonable. If you’re selling, anchor high. If you’re buying, anchor low. Be aware of anchors in your own decisions and try to question the first number you see.
