In House M.D., which fictional doctor is known for saying, “Everybody lies”?

In House M.D., Gregory House is the fictional doctor associated with the phrase “Everybody lies.”

The statement summarizes House's distrust of patients' accounts and his belief that people conceal facts, whether deliberately or because they misunderstand their own motives and symptoms. It becomes one of the character's best-known principles and helps explain why he investigates behavior as well as laboratory results.

The phrase is connected to the show's diagnostic method, but it is not a literal claim that every person lies constantly. House uses it as a provocative working assumption, encouraging his team to question incomplete histories and look for information patients may omit.

“Everybody lies” is often confused with the title of the series finale, “Everybody Dies.” The two phrases are related in tone but refer to different ideas: one concerns human testimony, while the other concerns mortality and the end of the series.
