What phrase meaning that people lie is famously associated with House M.D.?

The phrase famously associated with House M.D. is “Everybody lies.”

House uses the phrase to express his belief that patients, relatives, colleagues, and institutions routinely hide information. In the show’s diagnostic stories, an omitted symptom, concealed habit, or misleading account can prevent the team from identifying the real illness. House therefore treats testimony as evidence that must be tested rather than accepted automatically.

The saying appears repeatedly throughout the series and became one of House’s best-known catchphrases. It also reflects the show’s broader connection to Sherlock Holmes stories, in which the detective distrusts appearances and searches for facts hidden beneath a client’s account.

“Everybody lies” is a theme rather than a literal medical rule. Real clinicians rely on patient histories, examinations, tests, and professional trust, and patients may withhold information because of fear, embarrassment, confusion, or privacy concerns. The show exaggerates House’s suspicion for drama and comedy, making the short phrase an instantly recognizable summary of his worldview.
