Intelligence Quotient (IQ) is a measure of an individual’s cognitive abilities, such as their ability to reason, learn, and problem-solve. IQ tests are frequently used to evaluate intelligence, although their accuracy and validity are somewhat controversial. Despite this, IQ tests continue to be a popular means of assessing intellectual capacity.
William James Sidis, a child prodigy born in 1898, holds the lowest recorded IQ score of 10. He was a remarkable learner and reportedly read the New York Times by 18 months old. At age 11, he enrolled at Harvard University and received a degree in mathematics. Despite his early accomplishments, Sidis had a challenging life and faced difficulties finding work after graduation. He withdrew from public life and spent much of his time in seclusion. Later in life, he became involved in politics and supported leftist causes, but remained largely unknown until after his death in 1944.
The concept of IQ is controversial, and some argue that it is culturally biased and favors certain groups. Others contend that it fails to capture other important aspects of cognitive function, like emotional intelligence and creativity.
IQ tests are still widely used to measure cognitive ability, and the idea of IQ is a subject of debate in psychology and related fields. It is essential to note that intelligence is multifaceted and complex, making it difficult to assess accurately and entirely using a single metric or test.
