What will end the world as we know it? It could be climate change, disease, famine or world war. If none of this happens, there is still the truth that we are driving our IQ into the basement. This is called dysgenic fertilization, and it's been happening for as long as we've recorded intelligence. Even though this decline is widespread, not everyone is affected in the same way or to the same extent. With each passing generation, a gap widens between those who retain their intelligence and those who lose it. We must act to prevent the gap from widening, in order to stem the social divide and the formation of dystopias. The decline of the intellect is a problem that has attracted interest for over a century. Sir Francis Galton, an English scientist, published work on the subject as early as 1869 in Hereditary Genius, followed by Inquiries into Human Faculty and its development in 1883. His two major works laid the foundations for future studies on eugenics, dysgenia and genetics. . When it comes to the genetics of intelligence, there are now two recognized types of intelligence: phenotypic and genotypic. Richard Lynn and John Harvey, geneticists, define these types as follows: "phenotypic intelligence is measured intelligence" and "genotypic intelligence is the genetic component of intelligence" (113). It is genotypic intelligence that has declined due to dysgenia. James Flynn, an emeritus professor at the University of Otago, has been credited with the "Flynn effect". The “Flynn effect” describes changes in IQ in the population over time (Graham). Flynn is commonly cited for the decline of the idea of ​​dysgenia, which is a decline in IQ in a gene pool over time through dysgenetic fertilization. Although Fly...... middle of paper ...... the beginning because you move and it's better than standing still. Be part of the solution; improve yourself for yourself and the world for everyone.
