Defining IQ
The Intelligence Quotient, or IQ, represents a numerical value derived from intelligence testing. This score encapsulates an individual’s cognitive abilities, reflecting their performance across various domains such as perceptual reasoning, verbal reasoning, memory, and information processing speed. A crucial element influencing this score is age, as it is juxtaposed with a mental age derived from the test results.

The Architecture of IQ Tests
IQ tests are meticulously designed to ensure that the average IQ hovers around 100, with a standard deviation of 15. Thus, scores ranging between 85 and 115 are deemed indicative of average intelligence. Scores exceeding 115 suggest above-average intelligence, whereas those below 85 signify below-average intelligence.
In essence, the IQ scale is segmented into three primary categories:
- < 85 – Below Average Intelligence
- 85-115 – Average Intelligence
- > 115 – Above Average Intelligence
While this framework provides a general overview, the scale’s nuances are more intricate. For a comprehensive understanding, one might explore the IQ Levels section or undertake an intelligence assessment to categorize one’s IQ accurately.

A Historical Perspective on IQ Testing
The origins of intelligence testing trace back to 1905, when French psychologist Alfred Binet and physician Théodore Simon developed the “Binet-Simon Test.” This pioneering tool initially aimed to gauge the intellectual capacity of children, determining their so-called mental age.
Over time, intelligence tests have evolved to reflect societal changes, adapting to contemporary realities, terminologies, and cultural contexts. Originally, these tests were instrumental in identifying individuals requiring educational support, evaluating whether students were progressing in line with their peers, lagging behind, or excelling.
Today, the “Terman-Merrill Scale” and the “Grace Arthur Scale” are among the commonly utilized tests. However, the Wechsler scale stands out as the most prevalent, offering specialized assessments for both adults and children. This scale is instrumental in evaluating knowledge, concentration, and cognitive functions.

Key Insights on Intelligence Quotient
It is essential to recognize that IQ is not a definitive measure of all intellectual capacities. While these tests are adept at assessing logical reasoning and abstract thought, they do not encompass the full spectrum of human cognitive abilities.
Intelligence quotient – fun fact!
Albert Einstein, the illustrious physicist renowned for his theory of relativity and Nobel Prize achievements, possessed an IQ of approximately 162. This impressive score places him among the intellectual elite and aligns with the threshold for membership in MENSA, the high IQ society.
