This is actually an exaggeration, not a real chin. More than 20 years ago, Professor Flynn of the University of Otago, New Zealand, investigated the intelligence test data of more than 20 countries and found a phenomenon: since the beginning of the 20th century, human IQ has been improving-the IQ score has increased by 0.3 points every year; 2 1 century, IQ increased continuously; And the growth is consistent, neither slowing down nor stopping, but rising steadily, just like being led by an invisible hand.

Rogers, a psychologist at the University of Oklahoma, analyzed the test scores of nearly13,000 American students, trying to find out whether Flynn said this phenomenon existed in a short time. The results show that students' grades improve slightly every year. For example, students born in 1989 will perform better than those born in 1988. There is no doubt that Rogers' research results provide another evidence for Flynn's statement.

Human intelligence has been steadily improving, which directly shows that children's intelligence will be higher than the average level of their parents 10 points. By the end of this century, the IQ of our descendants will be 30 points higher than ours-this is the IQ gap between ordinary people and the smartest people.

Scientists believe that the steady improvement of human intelligence is not the result of the continuous evolution of the human brain, but the result of the continuous progress of technology and culture. Moreover, this improvement will not continue at a uniform speed, and the future growth will become smaller and smaller, or even stop.

? At present, as a primate of all things, human intelligence is high enough. On this basis, will human brain evolve? Is there room for human wisdom to soar?

Scientists believe that if the human brain evolves again, there are only two possibilities, but both possibilities seem far away.

One possibility is that the brain is getting bigger. Previous studies have confirmed that the intelligence level of a species may depend on the nerve reserve of the brain. The larger the brain capacity, the greater the nerve reserve. When a person's brain gets bigger, his head will inevitably get bigger, so the overall height of the human body will inevitably get bigger, otherwise it will cause dystocia or stillbirth.
