But have you ever wondered how our cognitive abilities are measured? Intelligence Quotient (IQ) tests are designed to assess human intelligence, providing a numerical representation of our cognitive abilities compared to others in our age group.
The concept of IQ was introduced by French psychologist Alfred Binet in the early 20th century. IQ tests evaluate skills such as reasoning, problem-solving, memory, and mathematical ability, aiming to measure innate intelligence rather than knowledge gained through education or experience.
IQ tests produce a single score, normalized to a mean of 100 and a standard deviation of 15. A score of 100 is considered average, while scores above or below 100 indicate above-average or below-average intelligence, respectively.
However, IQ tests have faced criticism for their limitations. Some argue that they don’t capture the full range of human intelligence, while others point out that cultural biases can affect results. It’s essential to remember that IQ scores measure only one aspect of cognitive abilities, neglecting other vital aspects of human capabilities like creativity, emotional intelligence, and practical skills.
