Logical Fallacies
A logical fallacy is an error in reasoning. When used in a text, it can weaken an argument. Despite this, logical fallacies can still be quite persuasive, so it is important to be aware of them.
Logical fallacies are very common in all kinds of writing, including newspapers and advertisements. They can make incorrect assumptions about a topic or argue for a specific position without using any evidence.
- Loaded language refers to strong language that is used to elicit specific emotions out of readers to sway their opinions about a topic. The language is often strongly negative.
The so-called scientists who push these crazy doomsday-scenario theories about climate change on the unsuspecting public should be ashamed of themselves! They are perpetrating a hoax on the American public in order to advance their own interests at taxpayer expense.
The example uses strongly negative language against climate change in an attempt to elicit an equally negative response from readers. However, there is no supporting evidence for the claims being made. It instead relies on the readers' emotions alone to garner support.
- A sweeping generalization takes a generally accepted belief about something and tries to apply it to every instance that relates to it without taking into consideration any exceptions.
Great musicians die young. Wolfgang Amadeus Mozart, a classical music prodigy, died at the age of 35. Buddy Holly was a singer and guitarist who helped pioneer rock and roll in the 1950s, and he died at the age of 22. Jimi Hendrix, known as the most influential electric guitarist in popular music, died when he was only 27 years old. Jennifer is a great musician, so she will unfortunately die young.
This example takes a general idea — many great musicians have died young — and applies it to all great musicians without considering any exceptions. Sweeping generalizations are conclusions that have been drawn using incomplete information.
Other Common Logical Fallacies
• Hyperbole
• Emotional Appeal
• Stereotype
Logical fallacies are used as evidence to support an argument, but they make incorrect assumptions about certain ideas or are just not related to the topic at hand. It is important to be able to pick out logical fallacies in writing so that you can more critically evaluate texts and avoid using them in your own works.
