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.
合成の誤謬の典型的な例は、一人が立ち上がるとよく見えるからといって、全員が立ち上がっても同じとは限らないことだ。
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.
The opposite fallacy: assuming what is true of the whole must be true of its parts.
From 合成 (composition) + の + 誤謬 (fallacy). A direct translation of the English logical term 'fallacy of composition'.
