合ごう成せいの誤ご謬びゅう

noun

fallacy of composition

A logical fallacy where one assumes that what is true for a part is also true for the whole. Used in philosophy, economics, and critical thinking contexts.

• 合ごう成せいの誤ご謬びゅうの典てん型けい的てきな例れいは、一人ひとりが立たち上あがるとよく見みえるからといって、全ぜん員いんが立たち上あがっても同おなじとは限かぎらないことだ。

  A classic example of the fallacy of composition is that just because one person can see better by standing up, it doesn't mean everyone will see better if they all stand up.
