A bright is a person whose worldview is naturalistic, that is, free of supernatural or mystical elements.* The term was coined by Mynga Futrell and Paul Geisert, a pair of brights from Sacramento, California, who thought it would be sensible to adopt a common name for atheists, agnostics, freethinkers, materialists, rationalists, secular humanists, and skeptics.* All these disparate groups share in common a naturalistic worldview.
Think about your own worldview to decide if it is free of supernatural or mystical deities, forces, and entities. If you decide that you fit the description above, then you are, by definition, a bright!
On this website, you can simply say so and, by doing so, join with other brights from all over the world in an extraordinary effort to change the thinking of society—the Brights movement.
