常见逻辑谬误:false cause/错误归因

false cause

You presumed that a real or perceived relationship between things means that one is the cause of the other.

Many people confuse correlation (things happening together or in sequence) for causation (that one thing actually causes the other to happen). Sometimes correlation is coincidental, or it may be attributable to a common cause.

Example: Pointing to a fancy chart, Roger shows how temperatures have been rising over the past few centuries, whilst at the same time the numbers of pirates have been decreasing; thus pirates cool the world and global warming is a hoax.

你从两个事物可能存在相关性,就得出一个事物是造成另一个事物的原因。

你看到了两个事物同时存在,就觉得其中一个事物是另一个的起因。你的错误在于,同时存在的两个事物未必有因果关系,可能这两个事物有共同的起因,或者两个事物根本没有因果关系,它们直接的共存只是巧合。一个事情比另一个事情先发生同样不能说明两个事物肯定存在因果性。

例子:Roger指出,过去几个世纪全球海盗数量减少,全球温度在升高,从而得出是海盗的数量的减少造成了气候变化,海盗能够降低全球温度。Roger犯了错误归因的谬误。
