The phrase “dumbest people in the world” is often used to describe people who are perceived to be unintelligent or foolish. However, there is no scientific basis for this term, and it is generally considered to be offensive and derogatory.
Intelligence is a complex and multifaceted concept, and there is no single definition that is universally accepted. Different cultures and societies have different standards for what is considered to be intelligent behavior, and what is considered to be dumb or foolish can vary depending on the context.
