Wilhelm Windelband on Nomothetic/idiographic - Dictionary of Arguments
Corr I 10
Nomothetic/idiographic/method//psychology/Windelband: Idiographic approaches study individuals, while nomothetic approaches seek generalizations and make comparisons based on the study of many people. This distinction, proposed by the German philosopher Wilhelm Windelband in 1892(1), was discussed by American personality psychologist Gordon Allport (1937)(2), who argued that idiographic traits that resided within individuals were the ‘real’ causes within personality. Windelband’s idiographic approach was what he called a ‘historical science’ in that it emphasized the history of one person (Maher and Gottesman 2005)(3). This approach requires considerable investigation of one person and so is suitable to psychohistorical investigation and to clinical applications.
Cloninger: A. Idiographic approaches produce understanding and offer intervention insights for particular individuals, whether through psychotherapy or behaviour modification. They are particularly useful for studying personality dynamics, that is, how motivated processes occur over time in an individual.

B. Nomothetic approaches, such as the Five-Factor Model, provide evidence for generality of concepts across the populations studied and are suited for studying individual differences, that is, identifying how one person compares with others. Nomothetic research is more often quantitative, expressed in mathematical measures, but some idiographic research (including behaviour modification reports and Cattell’s P-technique) goes beyond qualitative descriptions to include quantitative counts of behaviour.
