Unlocking Personality Traits: The Importance of Empirically Derived Inventories

What does it mean that personality inventories are empirically derived?

“Personality inventories (such as the MMPI) are questionnaires on which people respond to items designed to gauge a wide range of feelings and behaviors. Test items are empirically derived, and the tests are objectively scored. Objectivity does not guarantee validity; people can fake their answers to create a good impression (but may then score high on a lie scale that assesses faking). “

Empirically derived means that personality inventories are developed through a process of collecting and analyzing data from a large sample of people. In the case of personality inventories, this involves administering a set of questions or statements to a large group of individuals and analyzing their responses to identify patterns of personality traits and characteristics. The traits and characteristics identified through this process are then used to create a standardized personality inventory that can be used to assess an individual’s personality.

The use of an empirically derived approach in developing personality inventories has several advantages. First, it ensures that the traits and characteristics included in the inventory are based on empirical evidence rather than just theory or speculation. Additionally, it allows for a standardized approach to personality assessment, which helps ensure consistency and reliability across different contexts and applications.

Some examples of commonly used empirically derived personality inventories include the Myers-Briggs Type Indicator (MBTI), the Big Five Personality Traits Inventory, and the Minnesota Multiphasic Personality Inventory (MMPI). These inventories have been extensively researched and validated, and are widely used across a range of settings, including clinical and counseling settings, workplace assessments, and research studies.
