#37: Size Matters
This photo involves a fun game. Can you guess which jar contains more jam? Most people would guess the jar on the right contains way more jam than the jar on the left. However, would you believe that these two containers hold the same amount? The jar on the right is taller, so most people assume that it’s larger.

However, the base of the squat jar is way bigger. The wider circumference makes up for the jar’s lack of height. It’s hard to believe, but these jars are essentially the same size. It just goes to show how the shape of things can influence our perception. This is an important lesson to keep in mind when shopping at the grocery store. Always read the weight or package size!
