Detailed explanation-1: -Since then, the so-called “Flynn effect” has been confirmed by numerous studies. The same pattern, an average increase of over three IQ points per decade, was found for virtually every type of intelligence test, delivered to virtually every type of group.
Detailed explanation-2: -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-3: -The Flynn effect refers to the consistent upward drift in IQ test scores across generations which has been documented to be approximately 3 points per decade.
Detailed explanation-4: -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.
