The others invent their number. This one gets calibrated.
An IQ scale is only as good as the runs it is calibrated on. That is why the thinking test shows an honest range instead of a number for now — and here anyone can watch (and help) the calibration grow.

Where the runs so far fall
The milestones
- 5 full runs: the position curve appears — every full result sees its place among all runs so far.
- 300 full runs: the first provisional IQ scale unlocks — as a range with uncertainty, never as a bare point value.
- 1500 full runs: planned second calibration step — more stable norms and finer comparison groups. Every calibration step re-anchors all existing results for free.
What you can hold us to
These criteria were fixed before we built this page: if fewer than 30 new full runs arrive within four weeks of the next public calls, we freeze the calibration build-out — the test stays free to use, but we stop building and write the failure up here. A number that does not grow will never be dressed up on this page.
How we measure and calculate is documented openly on the method page — weaknesses included. Method and limits →
