Within the depth-psychology corpus, 'efficiency' occupies a profoundly ambivalent position. It appears not as a neutral technical descriptor but as a concept charged with moral, psychological, and civilizational stakes. James Hillman offers the most sustained and searching critique, tracing the Western genealogy of efficiency through Aristotle's four causes and arriving, devastatingly, at the Nazi death-camp administrator Franz Stangl — for whom efficiency became an absolute rule divorced from any final cause beyond profit, stripped of all ideals and passions. Here efficiency reveals its shadow: the reduction of purposive human action to mere mechanism, operating with lethal fidelity to procedure. In the trauma literature of Onno van der Hart and colleagues, efficiency is recuperated under the concept of 'mental efficiency' — following Pierre Janet — designating the capacity to focus and deploy available mental energy at adequate levels of integrative action. Low mental efficiency characterizes dissociative and traumatized states; improving it becomes the central therapeutic task. Antonio Damasio touches the term more briefly, noting that emotion modulates the style and efficiency of cognition. Karen Armstrong invokes efficiency as a hallmark of Western modernization and technological specialization. The tension between these registers — efficiency as pathological abstraction on one side, and as a necessary condition for psychological integration on the other — gives the term its peculiar richness in the corpus.
Nothing must interfere with the efficiency of the procedures... The absolute rule of efficiency.
Hillman exposes efficiency as the governing principle of the Treblinka death camp, where absolute procedural fidelity operated entirely without moral or teleological grounding.

Stangl's final cause was devoid of all ideals and passions; no other end but profit. No other end but profit.
Hillman demonstrates that efficiency severed from final cause — from 'that for the sake of which' — collapses into pure instrumentality, exemplified in Stangl's reduction of mass murder to financial motive.

There is an intimate and reciprocal relationship between mental efficiency and level of action tendencies... mental efficiency as the ability to efficiently focus and use whatever mental energy is available.
Following Janet, van der Hart establishes mental efficiency as a technical term denoting the capacity to focus mental energy into increasingly complex integrative actions, directly linked to the survivor's level of psychological functioning.

The term mental level indicates the ability to efficiently focus and use whatever mental energy is available in the moment. Mental efficiency includes the concept of integrative capacity.
Van der Hart defines mental efficiency as synonymous with integrative capacity, positioning it as foundational to the mental level and to the capacity to synthesize traumatic experience.

the principle of improving mental efficiency involves patients learning to master increasingly complex mental and behavioral actions that support adaptive living.
Van der Hart articulates improving mental efficiency as the therapeutic goal of graduated mastery over complex adaptive actions, including prioritization and long-term cost-benefit reasoning.

Trauma-related phobias are a major obstacle to improving mental efficiency and consume much mental energy.
Van der Hart identifies trauma-related phobias as the primary drain on mental efficiency, framing their resolution as both requiring and generating improvements in integrative capacity.

The lower this efficiency, the more likely it is that a survivor will engage in substitute actions rather than in action tendencies that demand high mental efficiency.
Van der Hart demonstrates that diminished mental efficiency in the apparently normal part of the personality produces regression to substitute actions and sustains dissociative avoidance.

a modification in the style and efficiency of the thought process... the signal of the body state (positive or negative) and the style and efficiency of cognition were triggered from the same system.
Damasio argues that somatic emotional signals and cognitive efficiency are co-regulated by the same neural system, so that affective states necessarily alter the quality and effectiveness of thought.

The achievements of one specialization were increased by their usage in another, and this in turn affected its own efficiency... an accumulative process.
Armstrong frames efficiency as the self-reinforcing dynamic of Western modernization, in which interdependent specializations amplify one another in a progressive, apparently unstoppable momentum.

One such delusional idea, showing more and more its rigor mortis yet still adhered to by practical men, is that of the bottom line.
Hillman contextualizes the cult of efficiency within a broader critique of defunct economic ideology, arguing that the 'bottom line' mentality externalizes true costs and enslaves civilization to a delusional abstraction.

a question from Mrs. Crowley about the decrease of efficiency through the mirroring process.
Jung notes in passing that the mirroring process — the discovery of a new self-standpoint through a newly differentiated function — may temporarily decrease psychological efficiency.
