Endowment Effect
🇳🇴EierskapseffektDefinition
The endowment effect is the tendency to assign higher value to things simply because we own them. Ownership increases reluctance to give something up, even when we would not pay the same amount to acquire it.
Real-world example
People often demand a higher price to sell an item they own than they would be willing to pay to buy it. In organizations, teams may cling to their own solutions and resist superior alternatives developed elsewhere.
Supplementary perspective
The endowment effect is closely related to loss aversion: giving something up feels like a loss, which weighs heavier psychologically than an equivalent gain.
Practical advice
Recognize
- —Ask whether you would value the item as much if you did not own it.
Counteract
- —Think in terms of trade-offs: what would you pay for it today?
- —Seek independent evaluations.
Ethical use
- —Leverage ownership feelings to increase responsibility and engagement.
- —Avoid exploiting the bias to impose unfair terms.
