What is Anchoring bias?

Anchoring bias is the tendency to rely too heavily on the first piece of information you hear when making decisions. That initial 'anchor' — like a starting price — pulls your judgment toward it, even when it's arbitrary or irrelevant.

Key things to understand

  • 1The first number or fact you encounter sets a mental reference point.
  • 2Later judgments stay biased toward that anchor.
  • 3It works even when the anchor is clearly random.
  • 4Retailers use it: a high 'original price' makes a sale look better.
  • 5Awareness helps, but anchors are surprisingly hard to ignore.

Frequently asked questions

What is an example of anchoring bias?
Seeing a $1,000 'original price' makes a $600 jacket feel cheap, even if $600 is more than it's worth — the first number anchors your sense of value.
Why does anchoring work even with random numbers?
The mind adjusts away from whatever starting point it's given but usually stops too soon, leaving the final estimate pulled toward the anchor.
How can you reduce anchoring bias?
Deliberately consider the opposite, gather independent reference points, and question where your first number actually came from.
