Personality has traditionally been assessed using self-report questionnaires. This self-report approach offers an insight into how the participant views themselves. However, research has shown that participants can and do ‘fake’ questionnaire responses, particularly in high-stakes situations. Additionally, their accuracy relies on the participant “knowing” themselves well.
On the other hand, Objective Personality Tests (OPT) offer a fake-resistant and objective measure, which is based on how the participant “behaves” while completing tasks. Participants do not know what is being measured so they do not know how to improve their scores. However, until now these tests have not measured the full range of Big-5 personality traits and related sub-traits.
Mosaic Personality Tasks offer the best of both worlds.
