Anchoring Bias
The tendency to rely too heavily on the first piece of information encountered (the "anchor") when making decisions.
Examples
- A store marks a sweater as "Originally $100, Now $60!" Even if $60 is the regular price, customers feel they're getting a deal because they're anchored to the $100 figure. Research shows items with higher "original" prices sell better, even when the final price is identical.
- Professional appraisers shown different suggested values for the same property tend to make final appraisals that correlate with those initial suggestions, despite their expertise and intention to be objective.
- Charity forms that list suggested donation amounts of $100, $50, and $25 typically receive higher average donations than forms suggesting $50, $25, and $10, as the higher initial number anchors donors to a higher amount.
