Garbage in, garbage out

"GIGO" redirects here. For the protein subunits, see Gi/Go. For the Japanese arcade chain GENDA GiGO, see Sega World.

In computer science, garbage in, garbage out (GIGO) is the concept that flawed, biased or poor quality ("garbage") information or input produces a result or output of similar ("garbage") quality. The adage points to the need to improve data quality in, for example, programming. Rubbish in, rubbish out (RIRO) is an alternate wording.[1][2][3]

The principle applies to all logical argumentation: soundness implies validity, but validity does not imply soundness.
