Anchoring Bias: The Hidden Force Skewing Every Negotiation You Enter
Anchoring bias shapes every price you accept and salary you negotiate. Here's what's actually happening in your brain — and how to fight back.
The first number you see in any negotiation isn't random — it's a trap, and most people walk straight into it.
Why it matters: Anchoring bias is the brain's tendency to over-rely on the first piece of information it receives, then use that number as a reference point for every judgment that follows. It affects salary negotiations, home purchases, car deals, and contract talks — basically every situation where money and decisions overlap.
By the numbers: In a now-classic study by Kahneman and Tversky, participants who spun a rigged wheel landing on 65 guessed significantly higher values in unrelated estimation tasks than those whose wheel landed on 10 — even though the number was completely arbitrary. A 2011 study published in Psychological Science found that lawyers who read a higher sentencing demand before deliberating recommended prison terms averaging 33% longer than those who saw a lower opening number. And according to research by Columbia Business School professor Adam Galinsky, negotiators who make the first offer in salary talks consistently close deals closer to their own target — not their counterpart's.
That last one is the part nobody talks about.
The bottom line: The anchor isn't just a starting point — it's a gravitational pull, and you're affected by it whether you recognize it or not. The best defense isn't willpower; it's setting your own anchor first, or deliberately generating a counter-reference before you walk into any negotiation.
