common myth

Widely believed fiction

A common myth is a widely believed falsehood—something many people accept as true despite lacking evidence or being demonstrably false.

The phrase often introduces corrections: It's a common myth that we only use ten percent of our brains.

Common myths persist through repetition, intuitive appeal, or cultural tradition rather than factual basis.
