Notes and Citations

Every source the book uses, chapter by chapter, with the apparatus the prose is not allowed to carry.

Three conventions. Where a specific page or section was confirmed, it is given. Where a claim was verified through a reputable secondary source rather than the original, that is stated, because the difference matters and hiding it would violate the standard the book claims to hold. And where an attribution was checked and failed, it appears here with the reason, since a cut is a finding.

Introduction: A Morning of Equations

Peter M. Gollwitzer, "Implementation Intentions: Strong Effects of Simple Plans," American Psychologist, 1999.

Peter M. Gollwitzer and Paschal Sheeran, "Implementation Intentions and Goal Achievement: A Meta-Analysis of Effects and Processes," Advances in Experimental Social Psychology, 2006. Ninety-four independent tests; a medium-to-large effect on goal attainment.

Ralph L. Keeney and Howard Raiffa, Decisions with Multiple Objectives: Preferences and Value Tradeoffs, 1976. Multi-attribute utility and the weighting of attributes in different units.

Daniel Kahneman and Amos Tversky, "Prospect Theory: An Analysis of Decision under Risk," Econometrica, 1979. Reference dependence and loss aversion, used here for why the drive-thru equation's terms are perceived rather than absolute.

Alfred North Whitehead, An Introduction to Mathematics, 1911. See Chapter 14.

Cut. Antonio Damasio, Descartes' Error, 1994. The somatic marker hypothesis is described in paraphrase rather than quoted, because a direct quotation could not be confirmed against the original text. The paraphrase claims only what secondary sources agree the book argues.

Chapter 2: "One cannot act upon that which has not been defined."

Percy W. Bridgman, The Logic of Modern Physics, 1927. "We mean by any concept nothing more than a set of operations; the concept is synonymous with the corresponding set of operations" (p. 5). "The concept of length is therefore fixed when the operations by which length is measured are fixed" (p. 5). "If a specific question has meaning, it must be possible to find operations by which an answer may be given to it" (p. 28). The star-and-goalpost comparison is at pp. 17–18. All four confirmed through the Stanford Encyclopedia of Philosophy entry on operationalism, which quotes the original with page citations.

Carl G. Hempel on the proliferation problem: strictly applied, operationalism would produce "a proliferation of concepts of length, of temperature, and of all other scientific concepts that would not only be practically unmanageable, but theoretically endless" (p. 96), also via the Stanford Encyclopedia of Philosophy.

W. Edwards Deming, Out of the Crisis, 1982. The chapter "Operational Definitions, Conformance, Performance" is confirmed as a chapter of that book through the MIT Press edition's table of contents. The three-part structure of an operational definition — a test, a criterion, a yes-or-no decision — is attributed to p. 277 by a secondary source and is described in the prose as paraphrase rather than quotation for that reason.

W. Edwards Deming, The New Economics, 3rd edition, p. 71: "There is no true value of any characteristic, state, or condition that is defined in terms of measurement or observation." Note that this frequently gets attributed to Out of the Crisis and belongs to the later book.

Gary Klein, Roberta Calderwood and Anne Clinton-Cirocco, "Rapid Decision Making on the Fire Ground," originally 1986, reprinted with a postscript in Journal of Cognitive Engineering and Decision Making, 2010. Twenty-six fireground commanders, mean twenty-three years of experience; 156 decision points probed; "in less than 12% of them was there any evidence of simultaneous comparisons and relative evaluation of two or more options"; in over 80 percent the commanders identified the situation as typical of a prototype and the action as typical for that prototype.

Gary Klein, "The RPD Model: Criticisms and Confusions," Psychology Today, 2021, for his own statement that the model has two components, fast non-conscious pattern matching and slower deliberate mental simulation, and for his acknowledgment that the evidence base is "fairly thin" under controlled conditions.

NASA Johnson Space Center, "Error Cost Escalation Through the Project Life Cycle," NASA Technical Reports Server document 20100036670. Three methods giving requirements-to-operations multipliers of 1:29, 1:157–186, and 1:1615 respectively. The authors state that the data "was somewhat limited in quantity and with respect to the details of the errors involved," that it came from two large aerospace projects, and that the third method rests on the author's experience rather than collected data. No author is named in the document as retrieved.

Cut. Definition by genus and differentia, routinely attributed to Aristotle. Aristotle used the term diaphora systematically but, on the available sources, had no explicit theory of it; the systematic treatment appears to be Porphyry's. The attribution in the form usually given could not be verified and the passage was removed from the chapter rather than softened.

* * *

Chapter 3: "Define every variable to its deepest identifiable condition."

E. F. Codd, "A Relational Model of Data for Large Shared Data Banks," Communications of the ACM, 1970. The requirement to eliminate nonsimple domains in reaching first normal form is at pp. 380–381.

E. F. Codd, The Relational Model for Database Management: Version 2, 1990, p. 6: values in the domains on which each relation is defined "are required to be atomic with respect to the DBMS."

C. J. Date and Hugh Darwen on the ambiguity of atomicity. Date: "the notion of atomicity has no absolute meaning." Their demonstration cases are character strings decomposing into substrings, fixed-point numbers into integer and fractional parts, and identifiers such as an ISBN into registration group, registrant, publication element, and check digit. Date's admission that "for many years I was as confused as anyone else" is quoted in the chapter.

W. Ross Ashby, An Introduction to Cybernetics, 1956. "Only variety can destroy variety," section 11/7. The formal statement that a regulator's variety must be at least as great as the variety of the disturbances it handles.

Jorge Luis Borges and Adolfo Bioy Casares, "Del rigor en la ciencia," first published in Los Anales de Buenos Aires, March 1946, under the joint pseudonym B. Lynch Davis, and attributed within the fiction to "Suárez Miranda, Viajes de varones prudentes, Libro IV, Cap. XLV, Lérida, 1658," an invented source. Collected in the 1946 second Argentinian edition of Historia universal de la infamia and later moved to El hacedor. Note the co-authorship: the piece is almost universally credited to Borges alone, and the chapter names both authors.

* * *

Chapter 4: "Don't make the specific unnecessarily vague."

H. P. Grice, "Logic and Conversation," 1975, pp. 26–30. The cooperative principle and the four maxims. The chapter uses the Stanford Encyclopedia of Philosophy's summary formulation rather than Grice's verbatim submaxims, which could not be confirmed against the original, and describes them in paraphrase accordingly.

George Orwell, "Politics and the English Language," 1946. "This mixture of vagueness and sheer incompetence is the most marked characteristic of modern English prose, and especially of any kind of political writing." "Political language... is designed to make lies sound truthful and murder respectable, and to give an appearance of solidity to pure wind." "A speaker who uses that kind of phraseology has gone some distance toward turning himself into a machine." All confirmed against the Orwell Foundation's text.

Rudyard Kipling's six serving-men, from "The Elephant's Child" in Just So Stories, 1902. The six question words are named in the chapter; the verse is not reproduced.

Eric M. Eisenberg, "Ambiguity as Strategy in Organizational Communication," Communication Monographs, volume 51, number 3, 1984, pp. 227–242. "The overemphasis on clarity and openness in organizational teaching and research is both non-normative and not a sensible standard." "I am not suggesting a retreat from clarity... What I am advocating is a shift in emphasis away from an overly ideological adherence to clarity toward a more contingent, strategic orientation." "Clarity is only a measure of communicative competence if the individual has as his or her goal to be clear." The four functions — unified diversity, facilitating organizational change, preserving privileged positions, enabling deniability — are given in the chapter.

Missing on purpose. The chapter's outline called for a second worked example drawn from Joe Lull, "Kimmel, Kirk, and the Worst-Intent Reflex," Medium, September 24, 2025. The piece could not be retrieved for this book and the example was omitted rather than reconstructed from memory.

* * *

Chapter 5: "The more we standardize the variables..."

Claude E. Shannon, "A Mathematical Theory of Communication," Bell System Technical Journal, 1948. Entropy as a measure of uncertainty removed, used here for the state-space argument and for the corollary that a system with no uncertainty transmits nothing.

Steven J. Spear and H. Kent Bowen, "Decoding the DNA of the Toyota Production System," Harvard Business Review, September–October 1999. "Every activity, connection, and production flow in a Toyota factory is rigidly scripted. Yet at the same time, Toyota's operations are enormously flexible and responsive to customer demand." "At Toyota it's the very rigidity of the operations that makes the flexibility possible," because operations function as "a continuous series of controlled experiments." The four rules are described by what each governs; their verbatim wording could not be confirmed from the available text and is not quoted.

David J. Snowden and Mary E. Boone, "A Leader's Framework for Decision Making," Harvard Business Review, November 2007. The domains and their action sequences: simple, sense-categorize-respond, best practice; complicated, sense-analyze-respond, good practice; complex, probe-sense-respond, emergent practice; chaotic, act-sense-respond. "Right answers can't be ferreted out." "Leaders who try to impose order in a complex context will fail." "The most frequent collapses into chaos occur because success has bred complacency."

Charles Perrow, Normal Accidents: Living with High-Risk Technologies, 1984. The two dimensions, interactive complexity and coupling; the finding that normal accidents occur where systems are both complex and tightly coupled; the argument that added safety devices increase interactive complexity; and the contradiction that tight coupling requires centralized control while complex interaction requires decentralized control, which "cannot be readily resolved."

Dropped. Wittgenstein on meaning as use was in this chapter's outline and is not in the draft. The argument it would have supported stands without the attribution, and the chapter carries six authorities instead of seven.

* * *

Chapter 7: "Do the same thing the same way every time..."

Walter A. Shewhart, Economic Control of Quality of Manufactured Product, 1931. "Postulate 2. Constant systems of chance causes do exist in nature." "Postulate 3. Assignable causes of variation may be found and eliminated." On the state of control: "This state of control appears to be... a kind of limit to which we may expect to go economically in finding and removing causes of variability" (p. 24).

W. Edwards Deming, the funnel experiment. Four rules: leave the funnel alone; adjust by the last error; reset from the target by the distance to the last drop; place the funnel over the last drop. Rule two leaves the drops spread roughly forty percent wider than rule one, which is variance doubled; rules three and four diverge. The classification of tampering as a Type I error — ascribing variation to a special cause when the cause belongs to the system — is Deming's.

Joseph M. Juran, the quality trilogy: quality planning, quality control, quality improvement. Control holds performance at the planned level and handles sporadic spikes; chronic waste is built into the standard and is invisible to conformance measurement; improvement moves the level deliberately, project by project.

* * *

Chapter 8: "Almost everything in life can be reduced to a quantifiable formula."

William James, The Principles of Psychology, 1890, Chapter IV, "Habit." Plasticity defined as a structure weak enough to yield to an influence but strong enough not to yield all at once; habit simplifying movement, increasing accuracy, and reducing fatigue. Note: the folded-paper and water-channel images almost universally attributed to James are James quoting Léon Dumont. The manuscript names Dumont.

Ann M. Graybiel, on chunking in the basal ganglia and on task-bracketing, where neurons fire at the start and end of a learned sequence and are quiet through its middle.

Herbert A. Simon, Administrative Behavior, 1947, and The New Science of Management Decision, 1960. Programmed versus nonprogrammed decisions; bounded rationality and satisficing; attention as the scarce resource.

Peter M. Gollwitzer, implementation intentions, as above. The 2006 meta-analysis reports ninety-four tests; a later synthesis reports effects ranging from small to medium-large across six hundred and forty-two tests, with larger effects for if-then format, pre-existing motivation, and rehearsal. Neither analysis addresses publication bias in its abstract.

Wendy Wood, on context cueing and on the proportion of daily behavior that is habitual: thirty-five percent in one study and forty-three in another, on undergraduates, over one and two days respectively.

Christopher D. Adams, "Variations in the Sensitivity of Instrumental Responding to Reinforcer Devaluation," 1982. Moderate training leaves responding sensitive to outcome devaluation; extended training does not.

Vázquez-Millán and colleagues, 2026, arguing that satiation-based devaluation frequently fails in humans and that habit-like responding concentrates in the participants for whom the procedure did not work.

Friedrich A. Hayek, "The Use of Knowledge in Society," American Economic Review, 1945. "The dispersed bits of incomplete and frequently contradictory knowledge which all the separate individuals possess." The knowledge of the particular circumstances of time and place.

Charles A. E. Goodhart, 1975: "Any observed statistical regularity will tend to collapse once pressure is placed upon it for control purposes."

Marilyn Strathern, 1997, for the compressed restatement: "When a measure becomes a target, it ceases to be a good measure." The familiar short form is Strathern's, not Goodhart's.

* * *

Chapter 10: "If it lives in your head, it should live in the 'system.'"

Michael Polanyi, The Tacit Dimension, 1966. "We can know more than we can tell." The face-recognition example. The claim that tacit knowing is a dimension of all knowing rather than a separate category.

David H. Autor, "Polanyi's Paradox and the Shape of Employment Growth," 2014, which names the paradox. His argument that the extent of machine substitution for human labor has been overestimated because the tasks resisting automation are governed by knowledge nobody can articulate.

Ikujiro Nonaka and Hirotaka Takeuchi, The Knowledge-Creating Company, 1995. The four conversion modes: socialization, externalization, combination, internalization.

Stephen Gourlay, "Conceptualizing Knowledge Creation: A Critique of Nonaka's Theory," Journal of Management Studies, volume 43, issue 7, 2006, pp. 1415–1436. Three of the four modes "appear plausible" but "none are supported by evidence that cannot be explained more simply"; the framework "omits inherently tacit knowledge."

Peter F. Drucker, on the knowledge worker and on the productive asset being owned by the worker rather than the firm.

* * *

Chapter 11: "We shouldn't PULL information, we should PUSH information."

Herbert A. Simon, "Designing Organizations for an Information-Rich World," in Martin Greenberger, ed., Computers, Communications, and the Public Interest, Johns Hopkins Press, 1971, pp. 37–52. What information consumes is "the attention of its recipients," and therefore "a wealth of information creates a poverty of attention and a need to allocate that attention efficiently among the overabundance of information resources that might consume it."

Donald A. Norman, The Design of Everyday Things, 1988, revised 2013. Knowledge in the head versus knowledge in the world.

Jakob Nielsen, "10 Usability Heuristics for User Interface Design," 1994. Visibility of system status is the first.

Mariano Felisberto and colleagues, "Override rate of drug-drug interaction alerts in clinical decision support systems: A brief systematic review and meta-analysis," Health Informatics Journal, 2024. Eleven studies, 570,776 prescriptions; pooled override prevalence 90 percent (95% CI 85.6–95.0); individual studies 65.3 to 97.9 percent. I² = 100 percent, indicating that the studies are not estimating a single underlying quantity. No systematic assessment of publication bias is reported.

Gloria Mark and colleagues, "Disruption and Recovery of Computing Tasks," 2007: eleven to sixteen minutes to resolve an interruption before returning to the original task. And "The Cost of Interrupted Work," reporting that interrupted tasks were completed faster than uninterrupted ones, with significantly higher stress.

Cut. The widely repeated figure of "23 minutes and 15 seconds" to recover from an interruption has no peer-reviewed source. It traces to interviews rather than to any published paper, and the primary papers do not contain it. It is not used in this book and the cut is stated in the chapter.

* * *

Chapter 12: "An efficient system minimizes the amount of user input..."

John Sweller, cognitive load theory. Working memory is sharply limited and load not intrinsic to the task competes with the task. No capacity figure is given in the prose, because the commonly quoted numbers vary by formulation and none was confirmed here.

James Reason, Human Error, 1990. Execution failures: slips, where a step of the plan is carried out incorrectly; lapses, where a step is omitted or forgotten. Planning failures: mistakes, from missing or misapplied knowledge; violations, where the rule is known and a decision is made not to follow it. The Swiss cheese model's distinction between active failures at the sharp end and latent conditions at the blunt end.

W. Ross Ashby, requisite variety, as above.

Lisanne Bainbridge, "Ironies of Automation," Automatica, 1983. "The designer's view of the human operator is that the operator is unreliable and inefficient, so should be eliminated from the system, but the designer who tries to eliminate the operator still leaves the operator to do the tasks which the designer cannot think how to automate." The vigilance problem, the skill-degradation problem, and the conclusion that automation increases rather than decreases the training an operator needs.

Poka-yoke is described as a practice of the Toyota tradition. It is commonly attributed to Shigeo Shingo; that attribution was not verified for this book and no personal attribution appears in the prose.

* * *

Chapter 14: "The more we reduce life's decisions to quantifiable formulas..."

Alfred North Whitehead, An Introduction to Mathematics, 1911, p. 61. "It is a profoundly erroneous truism, repeated by all copy-books and eminent people when they are making speeches, that we should cultivate habit of thinking of what we are doing. The precise opposite is the case. Civilization advances by extending the number of important operations which we can perform without thinking about them. Operations of thought are like cavalry charges in a battle—they are strictly limited in number, they require fresh horses, and must only be made at decisive moments."

William James, The Principles of Psychology, 1890, Chapter IV. "In habitual action, mere sensation is a sufficient guide, and the upper regions of brain and mind are set comparatively free." "The more of the details of our daily life we can hand over to the effortless custody of automatism, the more our higher powers of mind will be set free for their own proper work." "The great thing, then, in all education, is to make our nervous system our ally instead of our enemy."

John Maynard Keynes, "Economic Possibilities for our Grandchildren," 1930. "The standard of life in progressive countries one hundred years hence will be between four and eight times as high as it is to-day." "Three-hour shifts or a fifteen-hour week may put off the problem for a great while." Technological unemployment defined as "unemployment due to our discovery of means of economising the use of labour outrunning the pace at which we can find new uses for labour." And on the permanent problem: "how to use his freedom from pressing economic cares, how to occupy the leisure, which science and compound interest will have won for him," with his worry that this would be "a fearful problem for the ordinary person, with no special talents, to occupy himself."

David Graeber, Bullshit Jobs: A Theory, 2018.

Magdalena Soffia, Alex J. Wood and Brendan Burchell, "Alienation Is Not 'Bullshit': An Empirical Critique of Graeber's Theory of BS Jobs," Work, Employment and Society, 2022. European Working Conditions Surveys 2005–2015, samples from over 21,000 to nearly 30,000 respondents. 4.8 percent report rarely or never doing useful work, against Graeber's claimed 20 to 60 percent, and the proportion declined from 7.8 percent in 2005. Perceived usefulness correlates with management respect, ability to use one's own ideas, and having sufficient time to do the work well.

C. Northcote Parkinson, Parkinson's Law, 1955: work expands so as to fill the time available for its completion.

Chapter 15: "Where a data-based decision will not produce a genuinely better result..."

Paul E. Meehl, Clinical Versus Statistical Prediction: A Theoretical Analysis and a Review of the Evidence, 1954.

William M. Grove, David H. Zald, Boyd S. Lebow, Beth E. Snitz and Chad Nelson, "Clinical Versus Mechanical Prediction: A Meta-Analysis," Psychological Assessment, 2000. 136 studies met inclusion criteria from 163 identified. Mechanical prediction approximately 10 percent more accurate on average; weighted mean effect size 0.086. Forty-seven percent of studies (63) showed substantial superiority for mechanical prediction; 48 percent (65) approximately equal; 6 percent (8) substantial superiority for clinical prediction. In seven of those eight, the clinicians received more data than the mechanical prediction, and where clinical interview data were available the mechanical advantage increased. The authors note they had to ignore nonindependence of statistics within studies, resulting in overestimation of sampling error.

James C. Scott, Seeing Like a State: How Certain Schemes to Improve the Human Condition Have Failed, 1998. Legibility and its instruments; metis and techne; the scientific-forestry case, in which "the actual tree with its vast number of possible uses was replaced by an abstract tree representing a volume of lumber or firewood"; and the four conditions for large-scale planning disaster: administrative ordering, high-modernist ideology, authoritarian state power, and an incapacitated civil society.

Dropped. Hubert Dreyfus and Antonio Damasio were in this chapter's outline and are not in the draft, both for lack of verification.

* * *

Chapter 17: The Head-On Collisions

E. L. Trist and K. W. Bamforth, "Some Social and Psychological Consequences of the Longwall Method of Coal-Getting," Human Relations, volume 4, number 1, 1951, pp. 3–38. The hand-got and longwall methods; the loss of whole-task visibility; the social fragmentation across specialized shifts; the growth of supervision; and the principle of joint optimization of the technical and social systems.

All other sources in this chapter are cited above under the chapters where they first appear.

Front matter

Federal Rule of Evidence 403: "The court may exclude relevant evidence if its probative value is substantially outweighed by a danger of one or more of the following: unfair prejudice, confusing the issues, misleading the jury, undue delay, wasting time, or needlessly presenting cumulative evidence." The Advisory Committee Notes define unfair prejudice as "an undue tendency to suggest decision on an improper basis, commonly, though not necessarily, an emotional one."

Joe Lull, "Kimmel, Kirk, and the Worst-Intent Reflex," Medium, September 24, 2025, for "identify your bias, then set it aside." Joe Lull, "War in Iran Begins while War at Home Continues," Medium, June 22, 2025, for "I have no interest in being right."

* * *

A note on what this list does not contain

Four attributions were checked and removed: Aristotle on genus and differentia, the sole authorship of the 1:1 map, the twenty-three-minute interruption figure, and a Damasio quotation reduced to paraphrase. Two authorities were dropped for lack of verification rather than for being wrong. One example was left out of Chapter 4 because the source could not be retrieved.

Those seven absences are the only ones I know about. There are certainly others I do not, and a reader who finds one has found a real defect rather than a stylistic complaint, because the standard this book set for itself in the front matter is that a citation which cannot be confirmed gets cut rather than softened.
