Free IQ Test

There are many different standardized tests that can measure one’s IQ or “intelligence quotient”. The median raw score for IQ is 100 and about 95% of the population scores between 70 and 130. There are many factors that have been associated with IQ, primarily mortality and social status.

The most common IQ test is the Wechsler Adult Intelligence Scale. The tests typically have a very high statistical probability. There are several studies that prove that overall IQ begins to depreciate starting in beginning adulthood. However, an exact peak age for the overall world population is still unknown.

IQ is both environmentally and hereditary. However, it is difficult to prove that a high IQ is hereditary because children typically grow up in the same kind of environment that their parents did.

It is believed that William James Sidis had one of the worlds highest IQ’s with an IQ ranging between 250-300. He knew over 40 different languages and went to Harvard at age 11. Other geniuses include Stephen Hawking (IQ 160), Judit Pulgar (IQ 170), and Kim Ong-Yung (IQ 210).
