GIGO or Garbage In Garbage Out, in computing, represents erroneous data entered into systems results in erroneous output. In other senses, it means bad result with bad input. In systems, it is often used to influence management decisions to consciously re-enter data while migrating to a new system, rather than dumping from the legacy system.
Another acronym, KIBO or Knowledge In, Bullshit Out, is what happens when valuable input is disregarded or ignored, deliberately or accidentally, by a person or organization.
