About this site
What is 16pop?
16pop offers free sixteen-type and Four Colours questionnaires, plus Western astrology and Zi Wei cultural exploration. No account is needed.
Understanding the tests
Our independently written personality questionnaire describes response preferences on continuous dimensions. It is not the official MBTI® assessment, is not affiliated with 16Personalities, and is not a diagnosis or a measure of career or relationship suitability. Four Colours is not the official FPA assessment and has not undergone reliability or validity testing.
Scope of birth charts
Astrology and Zi Wei are cultural and entertainment interpretations, not scientific predictions. Birth time, location and historical time zones affect calculations. Natal readings describe traditional symbolism. Decade stages use the existing age intervals, not predictions of events. No daily, monthly or transit forecasting model is implemented.
