What is IQ

Simply speaking, IQ (intelligence quotient) is an assessment of your ability to think and reason.

The first IQ test was developed by French psychologist, Alfred Binet in 1905. His test has provided the base for all modern IQ tests widely used today.

However, the interest of scientists and psychologists in intelligence dates back to thousands of years. Though a number of small studies over intelligence were carried out from time to time, it was in 1859 when concrete experiments and studies over the concept of IQ started after the publishing of Charles Darwin's "The Origin of Species".

Improve your IQ

The million-dollar question: Can IQ be improved?

Scientifically speaking, yes!

Just a few years back, the IQ of a human being was considered as something that is genetic and cannot be improved upon. However, various researches by eminent scientists and neuropsychologists have proven this myth wrong.

A study at Michigan University led by Swiss postdoctoral fellows Susanne M. Jaeggi and Martin Buschkuehl has revealed..
