The method, no smoke
Our questions follow the formats of the reference psychometric batteries — series, matrices, classification and arithmetic reasoning — and are originally authored. Each one undergoes difficulty and discrimination analysis with real data: the ones that don't work get retired. The norms behind your percentile are recalibrated as more people complete the test.
What does 100 ± 15 mean?
IQ is expressed on a scale where 100 is the population mean and 15 the standard deviation: two out of three people score between 85 and 115, and only 2% exceed 130. That's why your result comes with a percentile: it places you, it doesn't label you.
