In [[control theory]], '''first-order control''' is when a desired result is attempted by adjusting a scalar (first-order) control. Such mechanisms, where first-order change successfully produces desired results, are called ''first-order mechanisms''.  First-order control is contrasted to [[higher-order control]].  While many simple mechanisms are completely first-order, most complex mechanisms are only first-order within a range of operation.  There are two types of first-order control theories; that referencing mechanisms, and that referring to [[social theory]].

A first-order control mechanism is any mechanism that is controlled by direct motion in a single direction.  Similarly, in social theory, a single direct action producing a social change is a first-order control system.  Many common beliefs about social organization, such as  "Increasing police decreases crime", or "corruption can be combatted by legislation" imply a first-order mechanism.
