Who is the proponent of the Paired Comparison Method?
Detailed Explanation
📌 Core Theoretical Concept:
The Paired Comparison Method was propounded by the renowned American psychologist Louis Leon Thurstone (L.L. Thurstone) in 1927. This psychometric scaling technique is used to measure psychological attributes, attitudes, preferences, and values on a quantitative scale. In this method, respondents are presented with pairs of stimuli and are asked to choose which stimulus in each pair is preferred or possesses more of a given attribute. Based on these choices, Thurstone formulated the 'Law of Comparative Judgment', which revolutionized psychological measurement by converting qualitative subjective judgments into interval-level quantitative data.
📊 Key Exam Points:
- L.L. Thurstone is also well-known in educational psychology for his Group Factor Theory of Intelligence and Thurstone's Equal-Appearing Interval Scale for attitude measurement.
- Charles Spearman proposed the Two-Factor Theory of Intelligence consisting of 'g' (general) and 's' (specific) factors.
- Alfred Binet is recognized as the father of modern intelligence testing, creating the first practical intelligence scale in 1905 with Theodore Simon.
- Thomson proposed the Sampling Theory of Intelligence, suggesting that intellect consists of a sample of various abilities.
📖 Theoretical Reference: In psychometrics and educational evaluation, measuring traits that are not directly observable requires robust scaling techniques. Thurstone's contributions bridge human judgment and statistical modeling. For further comprehensive studies, review Intelligence Theories and Psychological Testing and Measurement.

Deep Pedagogical Analysis:
Questions regarding matching pioneers with their respective psychometric methods or intelligence theories frequently appear in teacher eligibility tests like CTET, UPTET, DSSSB, and various state TET examinations. Aspirants must carefully memorize the specific contributions of prominent theorists like Thurstone (Paired Comparison and Group Factor), Spearman (Two-Factor), and Binet (Intelligence Scales). Understanding the foundational mechanics of scaling methods like paired comparison helps educators appreciate how subjective behavioral traits are translated into objective psychological metrics for effective educational assessment.
