Ask AI: true or false Performance on IQ tests have steadily increased over the generations. provide evidence proving your answer is correct

True. The phenomenon is known as the Flynn effect, named after intelligence researcher James Flynn. In his study, Flynn discovered that there has been a consistent increase in IQ scores across the globe over the years. From one generation to the next, IQ scores have generally improved by about three points. But this doesn't necessarily mean that each generation is "smarter" than the one before. Flynn noted that the increase could be due to several factors, including better nutrition, more and better education, and a stimulating environment, among others. The effect is most evident in developed countries, but similar patterns are seen in developing countries as they improve their educational and health systems. The Flynn Effect is widely recognized by psychologists and provides the evidence to prove the statement correct.

False. Studies have found that the average IQ score has remained roughly the same since the earliest IQ tests were developed in the early 1900s. For example, a meta-analysis of over 800 studies published in Psychological Bulletin found that IQ scores have been decreasing over the 20th century and that average IQ scores in the late 20th century were about 3 points lower than average IQ scores in the early 20th century.
