常见逻辑谬误:composition/division/合成谬误

composition/division

You assumed that one part of something has to be applied to all, or other, parts of it; or that the whole must apply to its parts.

Often when something is true for the part it does also apply to the whole, or vice versa, but the crucial difference is whether there exists good evidence to show that this is the case. Because we observe consistencies in things, our thinking can become biased so that we presume consistency to exist where it does not.

Example: Daniel was a precocious child and had a liking for logic. He reasoned that atoms are invisible, and that he was made of atoms and therefore invisible too. Unfortunately, despite his thinky skills, he lost the game of hide and go seek.

你认为一个总体的组成部分所具有的特性,对于这个总体的其它部分也是普适的。
很多时候,对于一个组成部分存在合理性的事物,对于其它组成部分并不具有合理性。我们常能观察到事物之间的一致性,所以当一致性不存在的时候也会偏见的认为有一致性。

例子:小红买了辆自行车,当她看到自行车的车座是人造革的时候,她就觉得自行车的其它部位也是人造革的。
