Five Labs examines the linguistic content of Facebook wall posts, pulling key words to make strikingly accurate estimates about individual personalities.
The method is based on a study published by H. Andrew Schwartz and colleagues from the University of Pennsylvania's World Well-Being Project. An advisor to Five, Mr. Schwartz’s research on language and personality was featured in the Public Library of Science (PLOS) in September 2013.
The application’s predictions are based around the Big Five personality traits: the leading personality theory in modern psychology. According to the theory, personality is based on the following five characteristics: extraversion, openness, neuroticism, conscientiousness, and agreeableness.
