The concept of IQ was first developed by French psychologist Alfred Binet in the early 20th century, initially to identify students who needed special educational assistance. The IQ score is usually calculated by comparing the test-taker's performance to that of a normed sample, typically within the same age group. An average IQ score is set at 100, with the majority of the population scoring within a range of 85 to 115. Scores below 70 may indicate intellectual disabilities, while scores above 130 suggest above-average intelligence or giftedness.

Having a high IQ often means that an individual has strong analytical, logical reasoning, and problem-solving skills. However, it is important to recognize that IQ is not the sole determinant of success or potential. Other factors, such as emotional intelligence, creativity, work ethic, and social skills, also play crucial roles in an individual’s overall abilities and achievements. Additionally, while high IQ can indicate strong cognitive abilities, it doesn't guarantee success in all life areas. Personal circumstances, educational opportunities, and individual choices also significantly impact life outcomes.
