Editing Fallacy of composition (section)

===In economics===
*  The [[paradox of thrift]] is a notable fallacy of composition described by [[Keynesian economics]].
* [[Division of labour]] is another economic example, in which overall productivity can greatly increase when individual workers specialize in doing different jobs. An individual worker may become more productive by specializing in making, say, [[hatpin]]s, but by satisfying the wants of many other individuals for a given product, the specialist worker forces other workers to specialize in making different things. What is true for the part (earning more by investing in the skills or equipment to make a given product faster) is not true for the whole (because not everybody can profitably make the same product).
* In a [[tragedy of the commons]], an individual can profit by consuming a larger share of a common, shared resource such as fish from the sea; but if too many individuals seek to consume more, they can destroy the resource.<ref name="Pigliucci_2012">{{cite book

* In the [[free rider problem]], an individual can benefit by failing to pay when consuming a share of a public good; but if there are too many such "free riders", eventually there will be no "ride" for anyone.<ref name="Pigliucci_2012"/>
