Abstract:
Language use is a psychologically rich, stable individual difference with well-established correlations to personality. Here, researchers describe a method for assessing personality using an open-vocabulary analysis of language from social media. Researchers built a predictive model of personality based on language using data from tens of thousands of Facebook users and their questionnaire-based self-reported Big Five personality traits. The model was then tested on a separate sample of Facebook users. Analysis of predictive langauge can provide rich portraits of mental life efficiently for very large groups.
