The lexical hypothesis suggests that important personality characteristics are encoded in language. This approach involves identifying and analyzing trait-descriptive terms found in a language's lexicon.
Allport and Odbert were pioneers in applying this methodology. In their foundational 1936 work, they undertook a comprehensive study of the English dictionary.
Their research aimed to identify and classify words functioning as personality descriptors. This systematic effort cataloged thousands of trait-related adjectives, laying the groundwork for subsequent research using the lexical approach to understand personality structure.
