Scientific State of Mind

Definition

The scientific state of mind is Jane Jacobs's reconstruction of what science is — not a body of knowledge or a profession but "a state of mind. Its aim is to get at truths about how reality works," distinguished from other truth-seeking pursuits "by the precise and limited intellectual means that it employs and the integrity with which it uses its limited means" (Jacobs 2004, p. 65). Its four stages: (1) a fruitful question — one that "must take into account, as far as possible, everything already known about the object, event, or process under scrutiny and, amid this richness of information, must single out a salient mystery or obscurity" (p. 66); (2) a hypothetical answer, framed "as elegantly and economically as possible — 'parsimoniously'" (p. 66); (3) testing — "Ultimately, the real world tests all hypotheses, and usually quickly. When answers from the real world seem to come slowly, it is seldom the evidence itself that is slow to appear; rather, observers are blind to evidence or emotionally can't bear to credit it" (pp. 66–67); and (4) the question chain — "a successful hypothesis opens up questions previously not even known to exist… This fourth stage, the question chain, sustains science as a coherent process, erecting continuous, coherent bodies of knowledge. Thus science itself, rather than the will of scientists or the judgments of patrons and grant givers, directs its own organization, along with providing automatic and continual self-renewal" (pp. 67–68). The two avenues — abstract (Why?/What?) and technology-driven (How?) — "work together so well that they frequently shift back and forth in the course of an investigation" (p. 69); feedback, "an information process analyzed by mid-twentieth-century computer scientists," is science's lifeblood: "In science, feedback is evidence" (p. 69).

The concept's negative pole is abandonment: "If a body of inquiry becomes disconnected from the scientific state of mind, that unfortunate segment of knowledge is no longer scientific. It stagnates. Intellectually, it is poisonous, because thereafter almost everything the stagnated and warped knowledge touches is harmed by it" (p. 69) — the gallery of stagnated dogmas including Nazi race ideologies, Marxist economics, and social Darwinism. Thomas Kuhn's paradigms supply the internal mechanism of lapse: outworn paradigms are "embroidered with qualifications and exceptions, along with labored pseudo-explanations — anything, no matter how intellectually disreputable or craven, to avoid losing the paradigm" (p. 70). Jacobs's three case studies are the chapter's demonstration method: traffic engineering (the "traffic is like water" paradigm disproven by the Washington Square closure and the Toronto street-direction test, and by the University College London finding that "an average of 20% of the traffic it carried seems to vanish" when a road is closed — a "fake science that cares nothing about evidence," pp. 72–79); the CDC's 1995 Chicago heat-wave study (eighty researchers pair-matching individuals, "worthless, because it turned up only what everybody already knew," against Eric Klinenberg's community-matching of North and South Lawndale, pp. 81–87); and the economists' failure to recognize the 2002 Toronto-area import-replacing boom because "such jobs don't fit into economists' preconceptions of how economies behave" (p. 88). The concept is a pillar-decay account: "The combination of the appearance of professional respect for scientific rigor coupled with professional contempt for scientifically rigorous behavior is toxic, a poison that infects more activities in North America than the few I have pointed out here" (p. 99).

Key Thinkers

• Jane Jacobs — the concept's theorist: the four-stage reconstruction; abandonment as pillar-decay; the three case studies (2004).
• Thomas Kuhn (not yet paged — see log) — the paradigm mechanism from The Structure of Scientific Revolutions on which the lapse theory rests (cited p. 195).
• John Snow, Edward Jenner, Louis Pasteur (not yet paged — see log) — the three nineteenth-century exemplars: environment-comparison (Snow's Broad Street pump), individual-comparison (Jenner's cowpox matching, ancestor of all placebo-controlled trials), and the How-question route (Pasteur's fermentation).

Related Concepts

• organized-complexity — the sister methodology from Jacobs 1961: the same respect for evidence and processes, applied to city problems; the "question chain" idea is the traffic analogue of the unaverage-clue doctrine.
• credentialing — the institutional enabler: degrees awarded for "this supposed expertise" are "perpetrating a fraud upon students and upon the public" (p. 72).
• boulevards — the built demonstration: the anti-boulevard dogma resting on "wholly unsupported… nothing more" (p. 150).
• import-replacing — the economic process the economists' paradigm-blindness hid.
• vicious-spirals — the dynamic: stagnated knowledge harming everything it touches as one turn in a spiral of cultural failure.

Open Questions

• Is the scientific state of mind a methodology or an ethic? Jacobs's formulation — "integrity… with which it uses its limited means" (p. 65) — suggests the latter, which would place the concept closer to professional ethics (self-policing) than to philosophy of science. Which framing does the traffic-engineering case support?
• The CDC/Klinenberg case is a method-choice failure (individual-matching vs. community-matching), not a fraud. Does Jacobs's framework distinguish incompetence from abandonment — and if not, is that a strength (all lapses are dangerous) or a weakness (the concept cannot tier culpability)?
• Jacobs claims science "has been making little progress in dealing with whole systems; particularly in biology and medical treatment, it tends to become arrested in the stage of singling out isolated bits" (p. 99). This anticipates the systems-biology and complexity literatures — is the wiki's organized-complexity page the right bridge, and does Jacobs's 1961 Weaver framework answer her own 2004 complaint?
