Bowker and Star, “Sorting Things Out” (1999)

What it is An ethnographic study of classification systems and information infrastructure, and the deepest criticism of ontology work in this corpus. Reviewing it, Terrence A. Brooks writes that “it is the accomplishment of this book to recognize classification itself as an object of study, as a vehicle for ethnography,” and that the effect of its examples “is to illustrate how values, policies and modes of practice become embedded in large information systems and become expressed in classification systems.” The book’s best-known concept is torque. Stefan Helmreich’s review essay gives the definition: Bowker and Star “introduce the force metaphor of ‘torque’ to describe the process that unfolds when ‘the “time” of the body and of [its] multiple identities cannot be aligned with the “time” of the classification system’.“ Helmreich adds that “individual biographies are twisted into tortured shapes” where the scheme and everyday life do not line up, and that Bowker and Star “argue that there is no experience of torque for those in power.”

The account below follows Brooks’s and Helmreich’s reviews and Eric Nehrlich’s reading notes; the primary text has not been read for this note.

Key concepts

• The International Classification of Diseases. On Nehrlich’s account, “developing this classification took many years and there are still many disagreements over it.” “Tropical countries believe that tropical diseases are grossly underrepresented compared to ‘rich-world’ diseases like cancer and heart disease.” “In Japan, heart attacks are considered a low-status way of dying, so death certificates will often list a stroke as the cause of death, leading to a skewing of results when compared to other nations.”
• Apartheid race classification in South Africa. Brooks describes “South African citizens who have been tossed back and forth between being classified as Whites, then Coloreds, then back again”; Nehrlich records that “a government declaration of one’s race forced one to change residences, jobs and families.” Helmreich works through a case where a boy classified as Asian at birth would, on reaching majority, be reclassified African under a different statute. Reading that as a category acting on a person rather than describing one is my gloss, not theirs.
• Tuberculosis patients, wholly dependent on a doctor’s diagnosis for their own status.
• The Nursing Interventions Classification. “Nurses were asked to describe what they do, so that it could be classified, standardized, and integrated into a billing system.” “Some nurses cheered the fact that they would now be ‘in the system’. Others were aghast that they would not be free to do what they thought was right.” Nehrlich notes that in this case “the tension between the system, and between the local adaptations one has to make for the system to actually function, was made clearly evident.”
• Black-boxing. “Classification systems tend to get black-boxed, in the sense of Bruno Latour. They tend to become invisible, and we forget how much effort went into creating them, and the political and ethical issues that were bound up in their creation.”

How you’d use it Use torque as a review question on any operational ontology: when a real case does not fit a category, who bears the cost? Helmreich’s point that “there is no experience of torque for those in power” is the sharp end of it — if the cost lands on a person outside the room, the modelling decision is a policy decision and should be made accordingly. Nehrlich’s second lesson is the companion: “there will always be elements which do not slot neatly into a category. But it is important to remember that this is not a reflection of the element — it is a reflection of the inadequacy of the system.” His example is the platypus.

Pitfalls & lessons The book’s argument is not that classification is avoidable. It is that classification is consequential and usually invisible, so the only real choice is whether the consequences are examined. Brooks objects that “the survey treatment … leads to multiple examples that pile on and do not advance the argument,” that “the research challenge is to take the next step and establish certain classification characteristics are associated with certain human, linguistic or institutional characteristics,” and that the book “is, however, strangely disconnected from a large body of empirical, cognitive research in classification and categorization that already exists.” Take the case studies as demonstrations rather than as a predictive theory.

Verdict Worth deeper study, and the only book in this corpus that treats classification as a political act with named victims. Read it after you know how the machinery works, so the argument lands on something concrete.
