The most accurate IQ test, for a fraction of the costs
The BRGHT IQ test is the most innovative cognitive ability measurement, harnessing the power of the advanced 2PL IRT (Two-Parameter Logistic Item Response Theory) model into the first adaptive IQ test. This methodology offers unparalleled accuracy by considering both the difficulty of questions and the likelihood of a correct response.
With a diverse pool of over 2 million participants, each question has undergone meticulous refinement based on responses from those with similar IQ levels. Such a vast data set provides several advantages:
Granular Calibration: The extensive pool of participants ensures that each question is calibrated to a wide range of cognitive abilities, ensuring a more tailored testing experience.
Broad Representativity: It ensures that the test remains unbiased, culturally sensitive, and widely applicable to varied backgrounds.
Data-driven Precision: The immense volume of responses allows the test to focus on the most discerning questions, significantly minimizing measurement error.
In comparison to traditional one-size-fits-all IQ tests, BRGHT's approach ensures more precise and efficient results. While classic tests can be prohibitively expensive, the BRGHT IQ test offers unlimited testing with its comprehensive, data-backed results starting at only $19.95.
