Discrepancy Production vs Reduction

The distinction between discrepancy reduction and discrepancy production is the central theoretical disagreement between control theory (Carver & Scheier, 1981) and goal-setting theory (Locke & Latham) regarding human motivation (bib).

Control theory: discrepancy reduction

Control theory models motivation as a negative feedback loop — the same mechanism as a thermostat or a Kubernetes controller. A reference signal (goal) is compared against actual state; the discrepancy drives corrective action until the gap closes. The natural state of the organism, by implication, is rest: once the discrepancy is eliminated, the system is at equilibrium.

Locke & Latham call this “a mechanistic version of Hull’s drive reduction theory” and reject it on three grounds:

Machines do not possess internal motivational states or goals of their own — their “goals” belong to the machine’s builders.
Discrepancy reduction is a consequence of goal-directed behavior, not its cause.
The model cannot explain why people set higher goals after succeeding.

Goal-setting theory: discrepancy production

Bandura (1989) argued that goal-setting is “first and foremost a discrepancy-creating process.” After attaining a goal, people generally set a higher one — producing a new gap to master rather than settling into equilibrium. Motivation therefore requires feed-forward control in addition to feedback.

The full motivational cycle is dual: “disequilibratory discrepancy production followed by equilibratory reduction” (Bandura, 1989, p. 38). First you create a gap (set a higher goal), then you work to close it — then you create a new, larger gap.

Connection to perpetual disequilibrium

This dual cycle maps directly onto the perpetual disequilibrium pattern in the knowledge base: the system never settles, and that’s correct. In desired state systems, the reference signal can be continuously raised — a property that pure negative feedback control does not explain.

Nuance in the knowledge base

The user’s xettel cards characterize Locke & Latham’s model as feedback control borrowed from cybernetics: “the goal is the reference signal, conscious judgment is the comparator, and action is the effector that reduces the discrepancy between goal and performance.” This captures the structural parallel but misses Locke & Latham’s central argument: the feedback loop is necessary but insufficient. The engine of motivation is the feed-forward act of setting new, harder goals — not the feedback act of closing the gap.

The structural parallel remains valid: goals do function as reference signals, feedback is essential, and the comparison mechanism is real. But the motivational source is not the loop closing — it is the loop being deliberately reopened at a higher level.

The Augmented LLM is the building block — both generator and evaluator are augmented LLMs
Connects to Discrepancy Production vs Reduction — the evaluator produces discrepancy (identifying gaps), the generator reduces it (fixing them)
Goal-Setting Theory applies: the evaluation criteria function as specific, challenging goals that drive performance

Goal-Setting Theory The user's xettel cards frame goal-setting as feedback control borrowed from cybernetics. The relationship is real but nuanced. Goals do function as reference signals, and comparison against performance is essential. But Locke & Latham explicitly argue that pure negative feedback (control theory) is insufficient: goal-setting is primarily a discrepancy-creating process. After attaining a goal, people set higher ones — producing new gaps rather than resting at equilibrium. This is closer to the perpetual disequilibrium pattern than to a thermostat. →

Goal Setting and Task Motivation (Locke & Latham, 2002) The paper explicitly rejects pure feedback control as the basis for motivation. Locke & Latham argue that Carver and Scheier's (1981) control theory — a negative feedback loop modeled on the thermostat — treats discrepancy reduction as the source of motivation, implying that the natural state of the organism is rest. Instead, they adopt Bandura's (1989) position: goal-setting is primarily a discrepancy-creating process. People who attain a goal set a higher one, producing new gaps to master. The dual cycle is "disequilibratory discrepancy production followed by equilibratory reduction." →

OKR (Objectives and Key Results)

Specific, difficult goals → OKR requires concrete objectives with measurable targets, scored so that 0.7 = success (i.e., targets are deliberately set above comfortable attainment).
Feedback → quarterly review provides the comparison between goal and actual state.
Goal commitment → collaborative goal-setting enhances strategy formulation (consistent with Locke & Latham's finding that participation's benefit is cognitive, not motivational).
Discrepancy production → aspirational OKRs deliberately create a gap the team cannot fully close, echoing Bandura's discrepancy production model.
