Detailed explanation-1: -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. It was first noticed by James Flynn.
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: -Per generation, the average IQ test scores increase by 10 points. This is called the Flynn effect, after the researcher who first documented this phenomenon. Thus it appears that people in 1950 were a lot less smart than they are now, that is if you define intelligence in IQ scores.
Detailed explanation-4: -The Flynn effect, which was discovered by James R. Flynn, is the fact that each generation scores higher on IQ tests than previous generations.
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.
