How Hirsch uses it

Every occurrence, grouped by book and chapter, with the claim it was linked to support and (where the extraction regenerated one) the underlying warrant.

2023 · Shared Knowledge
A book on readability that was ignored by the educational community.
related The American educational community ignores or dismisses evidence for shared knowledge because of deep intellectual, financial, and emotional investment in child-centered education.
ch 10 · expert_testimony · sk:ch10_E13
Bailin and Grafstein's analysis of specialized vocabularies in finance, sports (baseball, football, cricket), and medicine.
direct Domain-specific knowledge (e.g., electronic technology or football) is not necessarily related to general intellectual achievement.
ch 13 · empirical_study · sk:ch13_E2
Warrant (implicit): If specific domains of knowledge possess their own technical vocabularies that are not taught as part of a core academic curriculum, then proficiency in those domains is independent of general academic standing.
could fail ifGeneral intellectual achievement often correlates with the ability to acquire any domain-specific vocabulary quickly, potentially confounding the independence of the two.
Example of misunderstandings arising from a lack of knowledge regarding drug information conventions (legal protection vs. side effects).
direct A reader who lacks knowledge of specific drug information conventions may misunderstand discussions of side effects.
ch 13 · thought_experiment · sk:ch13_E3
Warrant (implicit): Understanding the communicative intent and pragmatic constraints of a specific professional field is a prerequisite for correctly interpreting texts produced by that field.
could fail ifReaders may use general heuristics about corporate behavior or legal skepticism to correctly infer intent without knowing specific pharmaceutical industry conventions.
2024 · The Ratchet Effect
Analysis by Professors Alan Bailin and Ann Grafstein in their book 'Readability' regarding the omissions in readability formulas.
direct Readability formulas are flawed because they omit elements like implication and disambiguation which depend on shared knowledge.
ch appendix-iv · expert_testimony · re:chappendix-iv_E13
Warrant (explicit): Mathematical formulas for text complexity are invalid if they do not account for the inferential processes required for human comprehension.
could fail ifReadability formulas are intended as proxy heuristics for text leveling, not as comprehensive models of the cognitive process of reading.
