Personality models, originally created in psychologic research, are today applied and used as assessment tool in very different fields: In therapy, education, in the human-resource sector, or as basis for many different personalised services in the tech industry. Beyond the Myers Briggs Type Indicator the NEO Personality Inventory is widely known and used. It is a further development of the so called five factor model by P. T. Costa, Jr., and R. R. McCrae.

Because this model with its scales can be easily used for data analysis, it is very common and also plays a major role in the data industry today. It is used there for the creation of psychometric profiles, for example for tailor-made advertisements aiming to adress the characteristics of person more specifically than by standard campaign posters.
