About what the free IQ test measures

Fluid intelligence is the measure of one’s simultaneous processing ability (which corresponds to the right hemisphere of the brain). This type of cognitive ability contrasts with crystallized intelligence which is a measure of all the learned materials that you encounter throughout your lifetime. Fluid intelligence cannot easily be learned and in a way determines how much you are able to invest in your crystallized intelligence and how your deal with information and chaos.
