More About Delusion

What is a delusion?

A delusion is a false belief or opinion, especially one held in resistance to strong evidence against it, as in Even after losing five straight championships, Heather still had the delusion that she was the best in the world.

In psychiatry, delusion is used to mean an unshakeable belief in something that isn’t true. They believe it because they have a mental disorder, such as schizophrenia.

More generally, delusion can be used to mean an act of deluding, as in The crowd didn’t fall for the swindler’s attempts at delusion.

Delusion can also refer to the state of being deluded, as in The emperor’s delusion was the work of the evil, scheming vizier.

Delusion is similar to the words illusion and hallucination, which also describe false beliefs or experiences. An illusion is a false image that is a result of a distortion or manipulation of actual things. For example, makeup can create the illusion that a person is younger than they actually are.

A hallucination is a false sensory experience that isn’t rooted in reality at all. On the other hand, a delusion is often somewhat based on reality but a person’s belief is inaccurate due to wrong information or their own hubris.

Example: Despite his low test scores, Gerard strongly believed the delusion that he was the smartest kid in the class.

Where does delusion come from?

The first records of the term delusion come from around 1375. It ultimately comes from the Latin dēlūdere, which means “to play false.”

When you have a delusion, you earnestly believe the false thing. If you don’t actually believe it, it’s not a delusion.

While psychiatric delusions are caused by mental disorders, general delusions are more often attributed to things like stubbornness, naiveté, or narcissism. Most of the time, we can admit we were wrong when someone shows us evidence that our belief is inaccurate. A person with delusions, however, will claim the evidence itself is wrong or fake, and it will take a tremendous amount of effort to convince them of the true reality, if they can be convinced at all.
