Logical Fallacy入门
Definition
Instead of addressing the opponent's argument, attempting to undermine their credibility by attacking their character, background, or motives.
Example
"You didn't even finish college, what right do you have to discuss economic policy with us?"
如何避免
将注意力集中在论点本身而非提出论点的人。问自己：即使换一个人说同样的话，这个论点是否仍然成立？
