IRT-style practice scores are not IQ tests, developer warns
IntelligenceMax uses an IRT-like formula to update learner estimates on an IQ scale after each answer. However, the item parameters are assigned by AI, not empirically calibrated. The developer notes the estimate supports adaptive practice but cannot substitute for validated IQ tests or prove broad cognitive gains.

A useful technical caution for edtech builders, but the real test is whether users or investors overinterpret the IQ-like output.
