Known Quantity is a small experiment in taking psychological measurement seriously without making it solemn or pretending a score can explain a person.
What happens to your answers?
Nothing leaves the measure page. Scoring happens in your browser. There is no account, database, answer tracking, or cross-measure profile. Close the tab and the answers are gone.
What makes a measure eligible?
Every instrument must have a license compatible with public, potentially commercial use. Public-domain item pools are welcome. “Free for research” is not treated as permission to publish, and proprietary clinical or commercial instruments are excluded.
Four operating principles
Say compared to whom. Percentiles name their norm sample and its limits.
Show uncertainty. Short measures are noisy; results should look as approximate as they are.
Describe trade-offs. Opposite ends of a trait can both help and cost you, depending on context.
Freeze published measures. Corrections receive a visible version note rather than silently changing the instrument.
