Why do people hang onto old keys?
Some keys continue opening things after the locks disappear.
An old key is surprisingly difficult to throw away.
Its lock may be gone.
Its building may no longer exist.
Still, people keep it.
The hidden mechanism is Spatial Anchoring. Physical objects help organize memory by giving emotions a place to live.
A worn key can represent:
- a first apartment,
- a childhood bedroom,
- an old friendship,
- or a version of life that no longer exists.
The cognitive scientist Donald Norman explained that objects carry emotional meanings beyond their practical uses.
Old keys are perfect examples.
People think they keep them because they are sentimental.
More often, they keep them because forgetting feels more permanent than losing the object itself.
