Interesting talk about IQ and intelligence

Same IQ, different life

  Langan is the person with the highest IQ in the United States at present, and his IQ test result is between 195 and 210. He taught himself advanced mathematics, philosophy, Latin and Greek. However, he was almost a failure in life and academics: he was bullied by his peers and beaten by his stepfather since he was a child; during college, he thought he knew more than his professors, so he dropped out and spent most of his life doing physical work The job, the low-paying job, and his genius title stand in stark contrast. Strangely enough, Oppenheimer, known as the “father of the atomic bomb”, had an IQ of 195, which is close to Langan’s. Why did Langan and Oppenheimer have very different lives with the same high IQ?

“Street smarts” is the accumulation of a person’s experience in the social process

  Some scientists believe that Langan, despite his high IQ, lacks an education in practical wisdom. Practical wisdom, also known as “street wisdom”, is the accumulation of a person’s experience in the social process. Langan was abused by his stepfather since he was a child, so he developed the habit of distrusting others and relying only on himself, which also led to his poor communication skills; while Oppenheimer’s family was superior, he learned from his parents’ ears and eyes since he was a child Deal with people and learn how to get what you want. Langan grew up in an environment where he lacked practical wisdom, so even if he had a super high IQ, he could only make a living by hard work in the end. It can be seen that a high IQ is not the only determinant of success.
What is the difference between intelligence and IQ?

  What is intelligence? This is a seemingly simple but difficult question to answer. In the story of “Cao Chong Calling the Elephant”, Cao Chong used the abilities of observation, logic, reasoning, planning, and arithmetic, which are all advanced cognitive abilities and belong to the category of intelligence. Intelligence is the ability of the brain to grasp and use information. British psychologist Spearman divided intelligence into general intelligence and special ability.

Intelligence is the ability of the brain to grasp and use information

  Later, Carter (a student of Spearman) and his students further divided general intelligence into “liquid intelligence” and “crystalline intelligence”. Crystalline intelligence is the knowledge a person accumulates, and liquid intelligence is the ability to apply knowledge to new things. For example, once you learn to ride a bicycle, you will never forget it, because you have crystalline intelligence, and you need to use your liquid intelligence to solve the Rubik’s cube. For some researchers, this theory of intelligence seems insufficient. Thus, the theory of multiple intelligences came into being.
  IQ is an artificial standard for judging intelligence, and IQ is not the same as intelligence. The IQ test gives a participant a score relative to the intelligence level of their peers by examining the participants’ logical reasoning ability, language use ability, spatial imagination ability, memory, judgment and other abilities, which is IQ. If the average IQ of a certain age group is 100, the IQ range of 80% of adults will be in the range of 90 to 110.

Don’t take IQ tests too seriously

  Nobel invented dynamite to revolutionize the mining industry, however, his invention soon became a weapon of war. Like dynamite, IQ tests have suffered a similar fate. When Binet launched the world’s first IQ test, he just wanted to help schools identify students who need special guidance and explore students’ potential in many ways. However, shortly after his death, the tests he left behind were used to measure individual intelligence. Thus, the notion that a number can reflect your intelligence level is widely accepted.
  Some scientists have questioned this outdated notion of intelligence. In fact, test scores and IQ scores are similar. Exams often have only one correct answer, but solving real-world problems often requires ambiguous “answers” or even compromises. IQ tests tend to measure a small range of recall and analytical skills, but cannot measure other abilities, such as creative thinking, practical problem-solving, and interpersonal skills, which are overlooked in a person’s life path. for important.
Smart people quarrel easily lose?

  ”The countless compliments I’ve received in my life make me feel at ease, and I can’t help seeing myself as a fraudster.” Guess who said this? The answer is the great scientist Einstein. Like Einstein, many high achievers always look down on their abilities and achievements, and this phenomenon often occurs in people with high intelligence levels.
  The “Dak effect” describes the phenomenon that “the less intelligent people are more confident.” After all, people with high intelligence and high cognitive levels are more likely to recognize their own limitations and the strengths of others. That’s why some laypeople will confidently and vigorously argue with professionals on issues they have no experience with.
  And when smart people think a problem is easy, they’re likely to think other people feel the same way, and therefore think they’re average. In addition, smart people generally develop the habit of learning new things and acquiring new knowledge, so they are more likely to realize that there is still much they do not understand, so they dare not be so decisive when drawing conclusions. If you are a scientist, before you declare that you have discovered a certain principle, you will carefully examine the data and information in your hands, worrying that others will point out the problem or ask you to give more sufficient evidence, so you will certainly be very concerned about yourself. Be very alert to things you don’t know or aren’t sure about. And this keen awareness often becomes a hindrance in a debate or quarrel, making it easier to lose.

Intellectually retarded people often immerse themselves in self-created advantages and overestimate their abilities
Why is it so hard to increase intelligence?

  It’s not hard to make people think you look smart, the hard part is how to actually be smarter.
  You know, intelligence does not come from a specific brain area, but is produced by several interconnected brain areas. More and more scientists believe that the strength of the connections between the brain regions involved in intelligence is the biggest factor affecting intelligence. Studies have also shown that the thickness of the corpus callosum (pián zhī) (the “bridge” between the left and right hemispheres) is also associated with general intelligence. The thicker the corpus callosum, the stronger the connection between the left and right hemispheres and the stronger the communication. In addition, when one side of the prefrontal cortex needs to recall memories stored on the other side, the thicker the corpus callosum, the easier and faster the recall. That is to say, people with higher intelligence have stronger and more efficient connections and associations between their brain regions.

  It can be seen that if you want to enhance intelligence, you have to improve the “efficiency” of the brain’s work. So, what exactly should be done? The answer is to keep learning. Learning new things changes the structure of your brain. Everything you learn strengthens your crystalline intelligence, and regular use of liquid intelligence to deal with situations will make you more and more adept at handling things. It takes a lot of time and long-term effort to increase your intelligence, and you can’t just do what you’re already good at or learned to do. It’s not worth showing off to be a master in a certain area. You need to give yourself new challenges all the time to keep your brain active for a long time, and your intelligence may be further strengthened.

  People’s research on intelligence has never stopped. So far, researchers have not come up with a theory of intelligence that everyone agrees with, but as scientists continue to explore the human brain, the public’s understanding of intelligence is also deepening.
Difference Between Liquid Intelligence and Crystalline Intelligence

  Neuroscientists have found by studying human brain activity: liquid intelligence is responsible for the prefrontal lobe (the location behind the forehead), and the prefrontal lobe shrinks more significantly with age than other brain regions; crystallized intelligence is dispersed throughout the brain. Long-term memory is often strong enough to withstand the erosion of time. That is to say, liquid intelligence declines as people age, while crystalline intelligence develops throughout a person’s life, but the rate of development gradually stabilizes after the age of 25. However, these two types of intelligence are actually interdependent—if there is no information available, it cannot be processed, and if it cannot be processed, the accumulated information is useless. Therefore, it is difficult to study the two completely separately, after all, the simplest tasks are completed by multiple brain regions.

Crystalline intelligence is the accumulated knowledge of a person. Liquid intelligence is the ability to apply knowledge to new things
Seven elements of success

  While it is true that the level of intelligence affects a person’s life to some extent, the factors that determine an individual’s abilities are diverse. The latest psychological research results show that success is related to seven factors, namely: grit, passion, self-control, optimism, gratitude, social intelligence and curiosity. One study found that intelligence and work experience play only about 15 percent of a person’s success at work.
Genetics also affects intelligence

  A 2014 study found that tall people are generally slightly smarter than shorter people.
  In addition to genetic factors, acquired efforts and external environments also affect intelligence to a greater or lesser extent, such as parenting styles, educational quality, cultural conventions, personal interests, and health conditions. These innate and nurtured factors are intertwined and together affect the development process and level differences of our intelligence. Studies have shown that 85% of the differences in intelligence between adults can be attributed to the role of genetics, while only 45% of the differences in intelligence between children can be attributed to the role of genetics. This is because: genetics and the outside world Factors jointly affect a person’s intelligence level. Children’s brains are still in the stage of development and learning, so there are various things that affect their intelligence levels; adults’ mature brains are relatively more ” stability”, the influence of external factors is not as strong, so the difference in intelligence between adults with the same level of education and similar growth environment is more likely to be caused by genetic differences.
