 Although we can treat the idea that manipulation consists of a form of pressure as a full-fledged theory of manipulation, most of the authors just cited hold only that some forms of manipulation consist of pressure. In particular, most agree with Faden, Beauchamp, and King, that other forms of manipulation are more akin to deception. Thus, it is somewhat artificial to speak of the pressure model as a theory meant to cover all forms of manipulation. It is more accurate to regard the pressure model as claiming that exerting non-coercive pressure is sufficient (but perhaps not necessary) for an influence to count as manipulative.
