Personality
A public-domain Big Five inventory with named scoring methods, comparison groups, and uncertainty bands.
Personality scores are most useful when the instrument, scoring method, and comparison group are visible. This section applies the public-domain IPIP approach to the Big Five, reports each score with its uncertainty band, and names the reference group used for comparison. It treats the result as a structured self-measurement, not a label, and keeps the scoring steps available for inspection.
