Analysis Of Personality

When studying human personality, psychologists may consider different levels of analysis. Personality can be viewed as characteristics typical of human nature and that we are “like all others” (Kluckhohn & Murray, 1953), as humans share the same basic biological components, experiences of development and social interactions. Alternatively, personality can be analysed in terms of individual and group differences, where we are “like some other[s]” (Kluckhohn & Murray, 1953). This approach considers that groups of individuals possess common characteristics, but that characteristics vary between individuals. For example, men are generally more aggressive than women, but one man may be more aggressive in comparison to another man. This level of analysis takes a nomothetic view on personality. Some theorists however may be more interested in individual uniqueness and take an idiographic approach to studying personality.
From the ancient Greek term idios meaning ‘private’ or ‘personal’, the idiographic approach emphasises that each individual is unlike any other and aims to develop an in-depth understanding of the individual by exploring their unique traits or personality variables. In contrast, the nomothetic approach - nomos meaning ‘law’ in ancient Greek - assumes that there is a limited set of variables that can be used to describe human personality and aims to identify the minimum number of these variables required to describe personality universally. The nomothetic researcher investigates “how and how much a particular individual is similar to or differs from others” (Shackleton and Fletcher, 1984) and therefore uses quantitative methods such as self-report questionnaires. From quantitative data psychologists can establish which p...

...f individuals, identify common themes and form hypotheses, and nomothetic methodology can then be used to investigate the theories.
Allport (1937) deemed science as nomothetic and psychology to be concerned with the study of individuals, suggesting that psychology is perhaps not a science, but by combining both the nomothetic and idiographic approaches, science and personality are combined forming a “science of personality” (Beck, 1953) . Allport (1960) reasoned that “unless such idiographic (particular) knowledge is fused with nomothetic (universal) knowledge, we shall not achieve the aims of science”. In which respect, by approaching the study of personality with both nomothetic and idiographic methodology, an agreement can be made that “Every man is in certain respects like all other men, like some other men and like no other men” (Kluckholm and Murray, 1953).
