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: -The Flynn Effect is the tendency of IQ scores to change over time, and specifically, the apparent increase in intelligence in the general population evidenced by a steady increase in IQ scores.
Detailed explanation-4: -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-5: -The improvement of medical and health sciences is one proposed explanation of the Flynn effect. The U.S. and Western industrialized nations have seen a great improvement in nutrition in the last century.
