The charge
Once we own something, we value it more than we did before owning it.
How it operates
Ownership turns giving it up into a perceived loss, and losses loom larger than equivalent gains.
Logged incidents
- Incident 01
A team refuses to sunset a feature after it becomes 'their product.'
- Incident 02
A company overprices a business unit it wants to sell.
- Incident 03
A candidate overvalues their current benefits package simply because it is already theirs.
What to watch for
It shows up when something seems worth more only after it becomes yours. Ask: 'Would I buy this today at this price if I did not already own it?'
Recommended action
Run a buy-versus-sell test or use separate people for valuation and ownership decisions.
Known associates
- Sunk Cost FallacyWe continue a failing course of action because we have already invested time, money, or effort in it.
- Escalation of CommitmentWe intensify commitment to a bad decision after negative feedback instead of cutting losses.
- Generation EffectWe remember and often value ideas more when we generate them ourselves rather than simply receive them.
- Loss AversionLosses usually hurt more than equivalent gains feel good, so we work harder to avoid losses than to pursue…
- IKEA EffectWe overvalue things we partly built ourselves.
- Unit BiasWe assume the provided unit, package size, or chunk is the right amount to consume, buy, or complete.
