Why do people hang onto old keys?
Some keys continue opening things after the locks disappear.
People keep old keys even when they no longer open anything because objects can outlive their functions. The hidden mechanism is Spatial Anchoring. A key preserves memories in physical form and allows people to revisit places that no longer exist in their lives.
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.
