As we have discussed, in academic writing, an argument must be logical to be effective and valid; therefore, it is important for students to be able to recognize problems with logic in their own writing or in the writing of others. These problems are often referred to as logical fallacies—defects in logic that weaken an argument. This lesson will examine a number of common logical fallacies.

Logical Fallacies

Circular Reasoning

Circular reasoning is when a writer tries to use the claim in order to support the claim. In other words, the argument goes around in a "circle" without actually presenting any new supporting points.

  • Skinny jeans are popular because many people are wearing them.

Sweeping Generalizations

This problem occurs when a writer believes the conclusion of a particular situation applies to all situations.

  • If a young person does not get a university degree, they will have no chance of getting a career.
