We often assume packaging is just a neutral container, but our expectations of what’s inside are deeply tied to how we use objects in daily life.

The Generic Nature of Shoe Boxes

When you buy a pair of shoes, the cardboard box is merely a disposable or reusable container. Once the shoes are purchased, there is no expectation that the box must remain filled with footwear.

The Commercial Purpose of Cookie Packaging

In contrast, a box of cookies is sold as a sealed unit. The packaging is integral to the product itself; finding it empty or containing something else implies a failure in the supply chain or prior consumption.

Mathematical Expectations

This asymmetry can be expressed formally through conditional probability:

$ P(text{no shoes} mid text{shoe box}) > P(text{no cookies} mid text{cookie box}) $
