Why this test can't be fooled

This is a lexical decision test, the method language researchers use (the well-known LexTALE test works this way). Real words and invented ones are mixed, and your score averages two things: how many real words you recognized, and how many fakes you correctly rejected. Say "real" to everything and the fakes drag you straight to 50% — chance level. Your verified word count applies the same logic per frequency band: guessing inflates your false-alarm rate, which is subtracted from every band. Honest skill is the only way up.

Frequently asked questions

How is this different from the self-report vocabulary test?
The self-report test asks you to check words you know — fast, but it relies on honesty. This check makes you judge every word as real or fake, so over-claiming is punished automatically: accepting fake words lowers both your accuracy score and your verified word count. Take both and compare!
What is a good accuracy score?
50% means pure guessing. Around 60–70% is typical for intermediate learners, 80%+ suggests advanced proficiency, and 90%+ is native-like — those are the ranges reported for LexTALE-style tests in research settings.
Can I get on the leaderboard?
Yes — unlike the self-report test, this score is objective and cheat-resistant, so it feeds a global leaderboard. Submit your accuracy score with a nickname after the check.
