Anchoring Bias – Definition & Examples

Definition: The tendency to rely too heavily on the first piece of information encountered when making decisions.

Detailed Explanation

Once we see a number, it 'anchors' our thinking—even if it's irrelevant. Salespeople use this by showing the high price first, then the 'discounted' price. In negotiations, the first offer strongly influences the final outcome. Awareness of anchoring helps make better decisions by questioning whether initial information should really matter.

Real-World Example

Real estate agents show overpriced houses first to make reasonably priced ones seem like bargains. Stores list 'original price: $100' crossed out next to 'sale price: $40' even if no one ever paid $100.
