IQ is an abbreviation for "Intelligence quotient". This quotient is a score, represented by number, which purpose is to define your intelligence. The abbreviation "IQ" comes from the German term Intelligenz-Quotient, originally coined by psychologist William Stern.

William Stern (1871-1938)

We should tell more about him, because he is the "father" of the idea to implement such test in order to define one human being' intelligence. He was a German psychologist and philosopher noted as a pioneer in the field of the psychology of personality and intelligence. William Stern decided that "personalistic psychology" or individuality was destined to be the psychological problem of the twentieth century. He attempted to classify people according to types, norms, and aberrations. To Stern, it was in the process of investigating individuality that the real essence of personality and intelligence could be discovered. Stern was influenced by the work of Binet and his studies of intelligence in children. As a result, Stern reviewed the principle findings in the field and developed the idea of expressing intelligence test results in the form of a single number, the intelligence quotient. This is a tribute to the author and we realize this site is functioning because of his discoveries in the field of psychology.
