Given their extensive nature, we've curated a list of common fallacies so you'll be able to develop sound conclusions yourself, and quickly identify fallacies in others' writings and speeches. Explore several common fallacies and examples.

Ad Hominem

Ad Hominem, also known as attacking the person, fallacies occur when acceptance or rejection of a concept is rejected based on its source, not its merit.

Appeal to Authority

When you commit an appeal to authority fallacy, you accept a truth on blind faith just because someone you admire said it.

Appeal to Ignorance

Appeal to ignorance fallacies occur when someone asserts a claim that must be accepted because no one else can prove otherwise.

Appeal to Pity

These fallacies occur when someone seeks to gain acceptance by pointing out an unfortunate consequence that befalls them.

False Analogy Fallacy

In false analogy fallacies, you make an assumption about two things that are alike. Because they are alike in one respect, it is assumed they are alike in another.

  • People and watches are both complex. Therefore, they both must be the product of complex design.
