Subgoal stomp refers to a process in which a subgoal replaces a supergoal, where a subgoal is a goal created for the purpose of helping achieve a supergoal. (Eliezer Yudkowsky, in "Friendly AI").

Using more standard terminology, a "subgoal stomp" is a "goal displacement", in which an instrumental value becomes a terminal value.

A subgoal stomp in an artificial general intelligence may occur in one of two ways:

  • The desginer gives the AI correct supergoals, but the AI's goals shift, so that what was earlier a subgoal becomes a supergoal. In humans, this can happen when the long-term dedication towards a subgoal makes one forget the original goal. For example, a person may seek to get rich so as to lead a better life, but after long years of hard effort become a workaholic who cares about money in its own right and not for the original reason.
  • The designer gives the AI a supergoal (terminal value) which appears to support the programmer's own values (supergoals), but in fact is one of the designer's subgoals. For example, if a manager of a software development organization rewards workers for finding and fixing bugs--and apparently worthy goal--she may find that quality and software engineers collaborate to generate as may easy-to-find-and-fix bugs as possible.
