The devices and techniques classed under PATELLA FLEXION are products of ISS research designed to assist field agents in social engineering, making use of hierarchy-based and submission instincts present in many sophont species. Rather than direct coercion or deception, the cerebroergetic and memetic technologies in this class function by projecting a comforting illusion of authority, designed to make its targets both well-disposed to and compliant with their user.
While effective (in proportion to the prevalence of said instincts; see relevant IES reports) in the former goal, they are of minimal use in the latter. Since PATELLA FLEXION leads the target to perceive the user as an authority figure communicating reasonable ideas – both observer-dependent – it can render actual communication (and thus persuasion of the target to do anything that they do not conceive their preferred authority-concept asking for from them) almost impossible. Worse, in some cases in which the target is hyperoneiric, it can trigger serious behavior excursions, often prejudicial to mission success.
