🌊 Big Five (OCEAN)
The five-factor personality model used in academic psychology — Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism — measured with the 50 public-domain IPIP items, scored live into five bars and a pentagon chart with a reading for each trait level.
🌊 Items from the International Personality Item Pool (ipip.ori.org, public domain) — the research-grade five-factor markers, self-scored. A snapshot, not a verdict: scores drift with mood, age and honesty of answers.
