A small sample.
A careful estimate.
Guessing correction
A wrong forced choice subtracts one third of a point. “I don’t know” carries no penalty and is the honest move.
Cautious uncertainty
We resample your answers 2,000 times to show a conservative estimate and a plausible 90% sampling range.
Public-beta limits
The denominator is a real, versioned 50,000-lemma dataset derived from wordfreq 3.1.1 / Princeton WordNet 3.0. The 100 editorial questions have not been calibrated on representative participants, so this remains an experimental estimate—not a validated assessment. Read the full methodology.
