An introvert in Baltimore, Maryland, is unhappy with an online definition of introvert, and is speaking up about wanting it changed. The definition describes an introvert as someone preoccupied with their own thoughts and feelings—such as a selfish person, or a narcissist. The problem is, Google’s definitions come from another dictionary, and dictionary definitions themselves come from perceived popular usage. So the way to change a definition isn’t to petition lexicographers, but to change the popular understanding of a term. This is part of a complete episode.
