What is stupid is as stupid does?

"Stupid is as stupid does" is a phrase originating from the 1994 film "Forrest Gump," which is based on the 1986 novel of the same name by Winston Groom. The line is famously delivered by the character Forrest Gump, played by Tom Hanks. It essentially means that a person's intelligence is demonstrated through their actions rather than their words or outward appearance.

The phrase suggests that people should be judged by the results of their behavior rather than preconceived notions about their intelligence or capabilities. Within the context of the film, Forrest Gump often defies society's expectations through his simple yet profound insights and his ability to achieve remarkable things despite being perceived as having a low IQ.

The message encapsulated by "stupid is as stupid does" is a reminder that wisdom and intelligence are best evaluated through a person’s deeds and choices rather than superficial labels or stereotypes.
