Note 23 — Chapter IV · THE CRITERIA OF POLITICAL TYPES
Reading edition
Allport really used a rank-order method of handling opinion expressions which he unjustifiably treated as marking definite positions along a base line. Thurstone has greatly improved the technique of opinion measurement. See Thurstone and Chave, The Measurement of Attitude (Chicago, 1929). For Allport’s original paper (with D. A. Hartman), see “Measurement and Motivation of Atypical Opinion in a Certain Group,” American Political Science Review, XIX (1925), 735–60.
