# What is the Fallacy Of Composition?

, updated on
The fallacy of composition is an assumption that something has the same properties as its parts. This assumption is often wrong as can easily be illustrated in examples:
---
Airplanes are made of composite materials
Composite materials are light
Therefore, aircraft are light
---
All cells are aquatic
All organisms are composed of cells
Therefore, all organisms are aquatic
---
Silicon and metals can't do math
Microchips are made of silicon and metals
Therefore, microchips can't do math
---
A runner who runs faster can win the race
If all runners run faster they can all win the race
---
In many cases, the composition fallacy is less than obvious. For example, many people might agree with a statement such as "a company that hires smart people makes smart decisions." However, due to factors such as the Abilene Paradox, such a statement isn't generally valid.
