Reward and Punishment Superresponse Tendency
The tendency of rewards and punishments to drive behavior — and even cognition — with far greater force than people intuitively assume. First on Munger's list of 25 Standard Causes of Human Misjudgment: he called incentives a 'superpower' and confessed he had underestimated their power his entire life.
“And, finally, somebody got the happy thought that it was foolish to pay the night shift by the hour when what the employer wanted was not maximized billable hours of employee service but fault-free, rapid performance of a particular task. Maybe, this person thought, if they paid the employees per shift and let all night shift employees go home when all the planes were loaded, the system would work better. And, lo and behold, that solution worked.”
“"Granny's Rule" provides another example of reward superpower, so extreme in its effects that it must be mentioned here. You can successfully manipulate your own behavior with this rule, even if you are using as rewards items that you already possess!”
Concept Analysis
Definition & Origins
Reward and Punishment Superresponse Tendency is Munger's name for the outsized power of incentives — rewards and punishments — to shape not only what people do but what they come to believe. It stands first in his list of 25 Standard Causes of Human Misjudgment because, in his judgment, it is the tendency most consistently underestimated even by people who study it. His confession is famous: he considered himself in the top five percent of his age cohort in understanding the power of incentives, "and yet I've always underestimated that power."
The intellectual lineage runs from Pavlov and Skinner through Munger's own business career. Where academic psychology demonstrated conditioning in animals, Munger documented it in boardrooms: compensation structures, sales commissions, accounting treatments, and status hierarchies quietly determining what intelligent people conclude is true. "Whose bread I eat, his song I sing" — the refrain he quoted when dissecting Westinghouse's catastrophic lending — states the law: cognition follows reward, usually without the believer's awareness.
Core Ideas
Incentives act on belief, not just behavior. The naive model says people pursue rewards deliberately; Munger's model says the reward first bends what seems true. The lending officer who is paid for loan volume does not consciously choose to ignore risk — the risk genuinely stops looking like risk. This is why Munger treated incentive analysis as the first question in any audit of human judgment, including his own.
Design beats exhortation. The Federal Express case is his canonical proof. The night shift could not be made to load planes fast enough; moral suasion and every conventional fix failed. Then someone noticed the company was paying by the hour while wanting fault-free, rapid completion of a task — the incentive rewarded the opposite of the goal. Paying per shift and letting crews leave when the planes were loaded fixed the system immediately. When behavior is wrong, Munger's reflex is to inspect the incentive, not to demand more virtue.
Reward superpower can be harnessed on yourself. "Granny's Rule" — the requirement that children eat their carrots before they get dessert — is Munger's favorite example of self-administered incentive design. Because prompt rewards work best (Skinner's teaching, as he noted), forcing the day's unpleasant and necessary tasks before the pleasant ones converts the tendency from a hazard into a tool.
Non-monetary rewards count. Money is the main driver among rewards, but not the only one: sex, friendship, companionship, and advancement in status all change behavior and cognition. Any analysis that looks only at the cash incentive misses the full reward field.
Practical Application
Auditing experts and institutions. Before accepting any professional opinion — auditor, analyst, consultant, executive — ask what the incentives want the answer to be. An opinion delivered against its author's incentives carries information; an opinion aligned with them may carry none.
Designing organizations. Assume every incentive system will be gamed exactly as written, not as intended. The system that rewards loan volume gets bad loans; the system that rewards billable hours gets hours, not results. Munger's Salomon and savings-and-loan post-mortems are case studies in incentive structures producing precisely the conduct they paid for, while everyone involved insisted they were respectable.
Self-management. Install Granny's Rule daily: unpleasant and necessary tasks first, pleasant tasks as the reward. And maintain humility about personal immunity — if the man in the top five percent of incentive-understanding kept underestimating their power, the correct prior is that you are being influenced right now in ways you cannot see.
Common Misconceptions
Misconception 1: Incentives only corrupt the weak. Munger's cases are full of able, honest people — Westinghouse's lending officers, Salomon's traders — whose judgment was bent by structure, not character. The tendency operates on everyone; character determines how far the bending goes before resistance, not whether it occurs.
Misconception 2: Stated intentions reveal effective incentives. Organizations describe their incentive systems aspirationally. Munger read them functionally: what does the system actually pay for, in money and in status? The gap between the two descriptions is where the superresponse lives.
Misconception 3: Awareness is a defense. Knowing about incentive-caused bias does not neutralize it — Munger, who taught it for decades, still reported being surprised yearly by incentive power. The only reliable defenses are structural: avoid the conflicted position, or build counter-incentives.
Munger's Own Words
"I think I've been in the top five percent of my age cohort almost all my adult life in understanding the power of incentives, and yet I've always underestimated that power. Never a year passes but I get some surprise that pushes a little further my appreciation of incentive super-power." — Charlie Munger, The Psychology of Human Misjudgment (Harvard, 1995)
"And, finally, somebody got the happy thought that it was foolish to pay the night shift by the hour when what the employer wanted was not maximized billable hours of employee service but fault-free, rapid performance of a particular task. Maybe, this person thought, if they paid the employees per shift and let all night shift employees go home when all the planes were loaded, the system would work better. And, lo and behold, that solution worked." — Charlie Munger, The Psychology of Human Misjudgment (Harvard, 1995), on the Federal Express case
"'Granny's Rule' provides another example of reward superpower, so extreme in its effects that it must be mentioned here.

Thought Evolution
Legacy & Influence
Placing this tendency first on the list of 25 was itself the teaching. Munger's canonization of incentive power — and his famous confession of having underestimated it all his life — converted a piece of folk wisdom ("Whose bread I eat, his song I sing") into the opening move of rational analysis. "Show me the incentive and I will show you the outcome" has become the most-quoted sentence in the entire Munger corpus because it compresses the whole discipline into one instruction: before you evaluate what people are doing or saying, find out what they are being paid — in money, status, or comfort — to do and say.
The tendency's legacy runs through three domains. In management practice, the Federal Express night-shift case entered the business-school canon as the standard proof that design beats exhortation — inspect the incentive before demanding virtue. In finance, the post-2008 autopsies read almost line-for-line as applications of Munger's framework: ratings agencies, originators, and bonus-structured traders each producing exactly the conduct their incentives purchased, each participant sincerely convinced of his own respectability. Regulators who had assumed disclosure and rules could overpower compensation design learned, expensively, the Munger theorem that no regulation survives a bad incentive. And in self-management, Granny's Rule has become the canonical illustration that the superresponse can be harnessed as well as feared — the same force that bends judgment can be aimed, by a sufficiently cunning self, at the day's most unpleasant necessary task.
Within the broader latticework, this tendency is the root node of Munger's applied psychology: Incentive-Caused Bias is its cognitive face, the agency problem is its institutional form, and most lollapalooza cascades begin with an incentive field pulling many tendencies in one direction. The first position on the list was a forecast about usage: in autopsies of human misjudgment, this is the tendency you will reach for most — and still, per its author's warning, underestimate.

Case Companies
Federal Express — The Night Shift. The integrity of the FedEx system required all packages shifted rapidly among airplanes in one central airport each night, and the company had, in Munger's words, "one hell of a time getting the night shift to do the right thing." Moral suasion failed; every conventional management fix failed. The resolution came from noticing that hourly pay rewarded duration, not completion. Per-shift pay with release when the planes were loaded aligned the incentive with the goal — and the system worked from that night forward.
Westinghouse — "Whose Bread I Eat." Westinghouse's lending operation made billions in bad loans to hotel developers because the officers making the loans were rewarded for volume and growth, and the accountants tolerated the "terrible accounting" that resulted. Munger cited the case to show that incentive-driven misjudgment is not confined to the weak or the stupid: the participants were displaying "the conduct predicted by the refrain: 'Whose bread I eat, his song I sing.'" The result was billions of dollars of losses.
Salomon Brothers — Incentives at Institutional Scale. The Treasury auction scandal of 1991 was not, in Munger's analysis, a conspiracy but a culture: a compensation structure that rewarded aggressive risk-taking and minimized compliance until fraudulent bids were the rational local response. Salomon demonstrates the superresponse operating at institutional scale — the incentive becomes the culture, and the culture produces the conduct.
