Detailed explanation-1: -The Flynn effect refers to a secular increase in population intelligence quotient (IQ) observed throughout the 20th century (1–4). The changes were rapid, with measured intelligence typically increasing around three IQ points per decade.
Detailed explanation-2: -The “Flynn effect” refers to the observed rise over time in standardized intelligence test scores, documented by Flynn (1984a) in a study on intelligence quotient (IQ) score gains in the standardization samples of successive versions of Stanford-Binet and Wechsler intelligence tests.
Detailed explanation-3: -According to the Flynn effect theory, the increase in IQ scores can in part be ascribed to improvements in education and better nutrition. In addition, people are reading more, and new technology-computers, Internet-forces people to think more abstractly. All of this leads to an increase in the IQ score.
Detailed explanation-4: -The Flynn effect is the substantial and long-sustained increase in both fluid and crystallized intelligence test scores that were measured in many parts of the world over the 20th century.
Detailed explanation-5: -Putting the “intelligence is inherited” argument to bed, the results have shown an interesting increase over the 20th century, known as the “Flynn effect". Put simply, IQ points generally increase by about three points per decade.
