常见逻辑谬误:special pleading/片面谬误

special pleading

You moved the goalposts or made up an exception when your claim was shown to be false.


Humans are funny creatures and have a foolish aversion to being wrong. Rather than appreciate the benefits of being able to change one's mind through better understanding, many will invent ways to cling to old beliefs. One of the most common ways that people do this is to post-rationalize a reason why what they thought to be true must remain to be true. It's usually very easy to find a reason to believe something that suits us, and it requires integrity and genuine honesty with oneself to examine one's own beliefs and motivations without falling into the trap of justifying our existing ways of seeing ourselves and the world around us.

Example: Edward Johns claimed to be psychic, but when his 'abilities' were tested under proper scientific conditions, they magically disappeared. Edward explained this saying that one had to have faith in his abilities for them to work.

当你的观点被证明是错误的时候,你用特例来给自己开脱。

人类都不喜欢被证明是错的,所以当他们被证明是错的时候总会想办法给自己开脱。人总是觉得自己以前觉得正确的东西必须是正确的吗,所以总能找到理由让自己阿Q一下。只有诚实和勇敢的人才能面对自己的错误,并且承认自己犯错了。

例子:小红说自己有特异功能,能用塔罗牌算出未出生小孩的性别,但是孩子生下来后发现猜错了,于是她就说是算命的人缺乏信仰。小红犯了片面谬误。
