Why the first number you hear quietly hijacks your judgment
💡 The first number you encounter becomes an anchor that biases your judgment — even when it's obviously arbitrary or irrelevant.
Imagine being asked whether Gandhi was older or younger than 140 when he died, then guessing his actual age. People given that absurd number guess higher than those first asked about age 9 — even though everyone knows 140 is ridiculous. This is the anchoring effect: the first piece of information you encounter becomes a mental reference point that pulls all your later estimates toward it.
Anchors work even when they're completely irrelevant. In one classic study, people spun a wheel of fortune rigged to land on 10 or 65, then estimated what percentage of countries in the UN were African. Those who saw 65 guessed far higher than those who saw 10 — a random number on a wheel silently shaped their answer.
The effect runs on adjustment: your mind starts at the anchor and nudges away from it, but almost always stops too soon. That's why the first offer in a negotiation, the crossed-out 'original price' on a tag, and the 'recommended' donation amount all wield outsized power. Salespeople and marketers lean on this constantly.
You can't fully switch anchoring off, but you can blunt it: notice when a number is planted before you, and deliberately generate your own estimate first before letting theirs in.
