Detailed explanation-1: -On average, IQ test scores worldwide have been increasing over time: younger generations perform better than older generations. 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.
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: -Each new generation is achieving better results in IQ tests. This effect is called the Flynn effect.
Detailed explanation-4: -Flynn, is the fact that each generation scores higher on IQ tests than previous generations. The cause of the Flynn effect is not known, but it could be due to what skills are being measured, better nutrition, education levels rising, and educational content focused on how to take tests.
Detailed explanation-5: -An example of the Flynn Effect is in intelligence scores. It is thought that if a person took an IQ test in the 19th Century, the average score would be significantly lower than it would be if that same person took an IQ test today.
