Language and behavior

A well-accepted theory of psychology, marketing, and other fields is that human language reflects personality, thinking style, social connections, and emotional states. The frequency with which we use certain categories of words can provide clues to these characteristics. Several researchers found that variations in word usage in writings such as blogs, essays, and tweets can predict aspects of personality.

A set of studies have been conducted to understand whether personality characteristics inferred from social media data can predict people’s behavior and preferences which in turn affect their workplace behavior. These conclusions make it even more important for us to explore the personality traits of individuals before we hire them:

Personality dimensions such as conscientiousness are related to job performance for all job groups they studied (professional, managers, sales, police, skilled, and semi-skilled).
People who score high on modesty, openness, and friendliness are more likely to spread information.
Individual differences in adaptability and its causes, correlates, and consequences. They found that conscientiousness, extraversion, and openness correlate positively with career adaptability.
Extraverted individuals are more satisfied in the workplace; work gives them an opportunity to experience an optimal level of arousal. Conversely, introverted individuals are less satisfied in the workplace due to too much stimulation
People with a higher self-enhancement value showed an interest in reading articles about work.
People with high openness are more intellectually curious and open to new ideas. Such people are therefore more likely to try new things.
People respond more positively to jobs tailored to their personality traits.
Conscientiousness is the personality characteristic that is most predictive of job performance.
Extraversion is positively correlated with leadership abilities.
Models we use
The Big Five personality model computes the five dimensions and 22 facets of the model. The dimensions are often referred to by the mnemonic OCEAN, where O stands for Openness, C for Conscientiousness, E for Extraversion, A for Agreeableness, and N for Neuroticism.
Needs are an important aspect of human behavior. Research literature suggests that several types of human needs are universal and directly influence workplace behavior.
Values convey what is most important to an individual. They are “desirable, trans-situational goals, varying in importance, that serve as guiding principles in people’s Behaviour”.
How personality characteristics are inferred
The Personality Insights service infers personality characteristics from textual information based on an open-vocabulary approach. This method reflects the latest trend in the research about personality.
AI first tokenizes the input text to develop a representation in an n-dimensional space.
Then AI uses an open-source word-embedding technique called GloVe to obtain a vector representation for the words in the input text.
It then feeds this representation to a machine-learning algorithm that infers a personality profile with Big Five, Needs, and Values characteristics.
To train the algorithm, the service uses scores obtained from surveys conducted among thousands of users along with data from their Twitter feeds, Social digital footprint and their professional digital data.
