Our Approach

Our assessments draw from established psychometric research — the Big Five personality model, standardized cognitive testing frameworks, and validated attachment and dark triad instruments. While our tests are designed for self-reflection and exploration rather than clinical diagnosis, they use real scoring methodologies to give you meaningful, accurate insights.

All results include the disclaimer that findings are for entertainment and self-reflection purposes. We do not claim clinical validity, and scores should not be used as a substitute for professional psychological assessment.
