Be mine: Our attachment to our stuff

I sometimes find myself wondering why people become attached to their possessions if, after all, our things are merely things. Our stuffed animals and blankets mattered to us as kids - but all our personal belongings hold special meaning to us as we grow older. My mug matters more to me than everybody else’s mugs; I might ask you to pay me $2 for the same mug I would only pay $1 for if  it wasn’t mine.  Why is this?

According to psychologists Daniel Kahneman, Jack Knetsch, and Richard Thaler, this “endowment effect” occurs because we experience something called “loss aversion” – which basically says we are more scared to lose than we are happy to gain. In their study they showed that just telling people they “owned” a mug changed how they felt about it - people would sell a mug they “owned” for $7, but would buy the same mug they didn’t own for $3. So it appears it hurts about twice as much to lose something that is ours than to gain something that isn’t ours.

The logic behind the endowment effect seems reasonable – we value what is familiar; we value our stuff.  You can learn more about the endowment effect in this article by Peter Worrell.
