Logical Fallacies
#01
Attack the Person
Attack the messenger

Ad Hominem

Attacking the person making the argument rather than addressing the argument itself.

'You can't trust his climate research—he drives an SUV!' Hypocrisy doesn't make an argument wrong. You're attacking the messenger to avoid the message.

It derails debate by shifting focus from ideas to personalities: we dismiss arguments because we dislike who's making them.

Politicians use it constantly: 'My opponent is corrupt, so their tax policy is wrong.' Two separate issues.

Separate the argument from the arguer. Terrible people can make valid points; saints can be wrong. Judge ideas on merit.

"Attack the argument, not the person."

1

Identify the personal attack

When someone shifts from the argument to attacking the person's character or credibility, flag it.

  • Watch for character attacks
  • Notice deflection from the topic
  • Separate person from argument
2

Refocus on the argument

Ask: 'That may be true — but what about the actual argument?' Bring it back to the claim and the evidence.

3

Evaluate ideas independently

Assess arguments as if they were anonymous. Would the logic hold if you didn't know who said it?

The source of an argument doesn't determine its validity.
