We are based on Harvard's prof. Cattell research

Our IQ Test is based on research and work from Harvard University professor Raymond Cattell, one of the most prominent psychologists of the last century.

Our test is an evolution of his first proposal of a "Culture Free Intelligence Test" to measure the raw potential of the mind, without taking into account "acquired knowledge and skill... different from intelligence".
