It's been more than a century since French psychologist Alfred Binet suggested a more modern way to assess intelligence. Since then, IQ tests have been used to separate those who are expected to achieve great things in life from everyone else. While some still consider a high score a clear indicator of great things, there are lingering questions about the accuracy and limitations of IQ tests. Having a high IQ elicits admiration and favor, but there is a wider argument to consider when identifying and measuring intelligence.
How do we define intelligence? One dictionary labels it as the ability to acquire and use knowledge and skills. Another states it is the ability to think, reason, and understand, without relying on automatic action or pure instinct. While these definitions are similar, the lack of agreement on exactly what it means to gain understanding or knowledge shows just how complex a test must be to accurately quantify one's ability and potential in all aspects of life.
