Why do some tourists overpack even when they know they won't use everything?
People pack for possibilities, not probabilities.
Almost everyone has packed something they never used.
And many people do it again on the next trip.
The hidden mechanism is uncertainty management.
Travel introduces unfamiliar situations. Weather changes. Plans shift. Items break.
People respond by carrying solutions in advance.
The problem is that the brain tends to exaggerate unlikely risks while underestimating the cost of carrying extra weight.
A third pair of shoes feels reassuring at home.
It feels unnecessary after dragging a suitcase across a city.
Behavioral economists call this possibility bias.
Humans often prepare for what could happen instead of what is likely to happen.
This explains why experienced travelers usually pack less.
They trust their ability to solve problems instead of carrying solutions for every scenario.
People often think luggage carries possessions.
Sometimes it carries worries disguised as preparation.
