Peer-Reviewed Methodology

Real Science, Not Guesswork

We use the same statistical methods as the Wechsler Adult Intelligence Scale (WAIS), the gold standard in clinical IQ testing.

Item Response Theory (2PL)

Each question has scientifically calibrated difficulty and discrimination parameters, just like professional IQ tests.

Discrimination: 0.7-1.7
Difficulty: -2.0 to +1.8
24 calibrated items

Maximum Likelihood Estimation

Your latent ability (θ) is calculated using MLE, then converted: IQ = 100 + 15×θ for standard Wechsler scale.
