How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to type is token.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Philosophy and logic

a general, repeatable kind, as opposed to its individual instances, which are tokens.

In the type-token distinction the type is a general, repeatable kind, as opposed to its individual instances, which are the tokens: the word "the" printed three times on a page is one type but three tokens, so counting kinds answers a different question from counting occurrences. Charles Peirce drew this contrast in his 1906 Prolegomena to an Apology for Pragmaticism, separating a general pattern from each concrete appearance of it. The referent is an abstract kind that can have many instances, a matter of logic and metaphysics, and it is not a classification of computer values, a preserved reference organism, or a category of person.[1]

Unit
One abstract kind, distinct from each concrete instance (token) of it
Recovery means
Not applicable
Measured by
Identified by abstraction: many tokens are recognised as instances of one shared type

Computer science

A classification of data values

A data type is a classification attached to a value in a program that fixes the set of values it may take and the operations that may be applied to it, so an integer, a boolean, and a string each admit their own legal manipulations. Cardelli and Wegner's 1985 On understanding types, data abstraction, and polymorphism set out how type systems classify values, catch meaningless operations before or as a program runs, and support abstraction and polymorphism. The referent is a formal classification of data that a language enforces, checked statically or dynamically, and it is unrelated to an abstract logical kind, a museum specimen, or a personality category.[2]

Unit
A classification of values, fixing the legal values and the operations on them
Recovery means
Not applicable
Measured by
Assigned and enforced by a type system, checked at compile time (static) or run time (dynamic)

Biology and taxonomy

A reference specimen anchoring a name

In biological nomenclature a type is the single reference specimen, most often the holotype, to which a species name is permanently attached, so the name is anchored to one physical organism rather than to a description that might later be judged wrong. Witteveen's 2015 Naming and contingency: the type method of biological taxonomy examined how this type method fixes the reference of a name to one designated specimen kept in a collection. The referent is a preserved organism that anchors a name, curated in a museum or herbarium, and it has nothing to do with an abstract kind, a class of program value, or a category of person.[3]

Unit
One designated reference organism (the holotype) that anchors a species name
Recovery means
Not applicable
Measured by
Fixed by formal designation under a nomenclatural code and deposited in a named collection

Psychology

A discrete category of person

A personality type is a discrete category into which a whole person is sorted, such as the sixteen Myers-Briggs types or the Type A and Type B labels, treating people as belonging to one class or another rather than lying somewhere on a graded scale. McCrae and Costa's 1989 Reinterpreting the Myers-Briggs Type Indicator argued that the data behind such types are better described by continuous traits, so the crisp categories mask underlying dimensions of degree. The referent is a bounded category of person, contrasted here with the continuous traits treated on the trait page, and it is not an abstract logical kind, a data classification, or a reference specimen.[4]

Unit
A discrete category a whole person is assigned to
Recovery means
Not applicable
Measured by
Assigned by a typological instrument such as the MBTI, though the data often fit continuous trait scales better
