About the Site

IN8NESS began in 2022 with the mission to provide easy access to science-driven personality insights. We aim to strike the balance between the entertainment and convenience of online personality "quizzes" and clinical personality assessments that are backed by science and much more informative, but that can be intimidating and expensive. We see a lot of value in offering personality tools that are easy to use, provide insights which have been validated by decades of research, and stay fresh by continually adding new insights as the science continues to develop.

Personality

Personality represents the innate and persistent thought, feeling, and action tendencies of individuals. It is a way to describe how people are alike and how they differ across the characteristics that drive their most salient everyday behavior.

The five factor model of personality (also known as the Big 5) is a trait theory describing the innate fundamental characteristics of individuals along underlying dimensions of openness, conscientiousness, extraversion, agreeableness, and neuroticism.

Five Factor Assessments

Methods for assessing personality have evolved over time and come in many formats. The usefulness of a given test is often defined in terms of its validity (does it measure something meaningful?) and reliability (are the measures consistent over time?). The assessments used on this site are based on peer-reviewed scientific research spanning decades. Find out more about them by clicking on the links below.

Social Outcomes of Personality

With an established methodology to assess personality (e.g., validated assessment tools for measuring the five factor traits), researchers have been able to systematically study how differences in personality are related to various social outcomes. These findings can help us understand more about how personalities influence our experiences in the world; perceptions of others; and are related to many social outcomes.
