It seems our upward trajectory just couldnt last forever. Is it possible that weve simply reached our peak . We all indeed getting stupid, older generations have always said, but young folk were not as smart as they were. Well, what if thats coming to the lets start here. Stupidity is not measurable. That gives me that intelligence is classic intelligence test question here to the minus 3 plus 2 minus 3 plus 2 minus 3. Thats 5, right . Thats fine. 5, people with a max for number sequences, rack up points on intelligence tests. But that ability is by no means you need to humans you think . And wed like to think were the crown of creation of, with our having become super intelligent vault and zion go from the initial guess id, we shouldnt lose sight of the fact that in the course of all level, lucian, we dont even make up a blink of an eye when taking certain tests, we fair worse than chimpanzees. For example. One comes on, this goes to show just how limited are working memory is, is a by on right now, the human can barely managed to remember more than 3 numbers in the correct position and sequence in the short amount of time. And for that, so a know so you, this young chimpanzee does it with instinctive certainty. So to fancies can beat us and the numbers test, and yet were developing highly complex technologies that doesnt seem to add up a minus the 2 are connected. What if were losing our brain capacity because of our intentions . Who drives anywhere without a Navigation System or memorize this phone numbers these days . Is Artificial Intelligence doing too much of that thinking forms to determine whether homo sapiens are truly in a down swing . First, we have to define the basics. What is intelligence anyway . Yeah. Intelligence intelligence is the ability to think logically and to reason. I think its all got to do with some cognitive reserves of thinking outside the box on energy does. It comes down to or brings capacity to solve problems here, and thats whats measured on intelligence tests and against test fax. The 2nd symbol, academic definition of intelligence, namely how high you score an i q test and an intelligence test. And why im into the guns test option. The 1st modern intelligence test was developed by french psychologist, else itd be ne, in 19 o 4. The intention wasnt to identify the brightest students. Rather, the ones falling behind as cop conduct a live of children who didnt learn to read rice and do mathematics in the time it was supposed to take. Its no matter how, how the teachers tried focusing on going to all intelligence tests, but also develop to determine who needed special education officials. During the 1st world war, the us military use the test to find qualified officers but there were also more sinister uses. Intelligence tests were intended to read out supposedly weak genes, the nazis term for it was racial hygiene, ty advisors in some cases when intelligence tests were administered to people from traditional cultures in africa, they couldnt do them simply because they have never before seen a circle or a square like that and use a phone to feed, and then they were deemed unintelligence guide. Today, universities and private high schools use intelligence tests to screen applicants in criminal proceedings. A very low i q can have a mitigating effect for sentencing. Tests are also used in psychotherapy, with children and adolescents, for example, to indicate developmental potential, the tones, what sound is to music . Not all intelligence tests are just about numbers. The language, so see thoughts as a sound as to music. As word is to language d, all the questions can be linguistic and nature. For example, you asked to evaluate the similarity between words. They can be numerical questions and theyre also figure all exercises of golf and the missing ok decided to there are objects that have to be folded or rotated mental exercises and sizes. And these are all activities that essentially try to split our thinking into adams when the thing come into a tool to split tests like these boil intelligence down to a single numerical value, the intelligence quotient or i q, intelligence, it seems is measurable. But those criticism couldnt be decent test. This test cant be used to measure other aptitude that are also extremely important for its actually such as social skills, emotional competencies for, for example, orienting yourself in the steps in the in depth step. Uh, the 1st im include take one criticism or centers on the compatibility of different cultures to critique is another critique, is that it doesnt measure a very important aspect which is finding a new solution and then use the tuition or what we call creativity of sales. Could actually take the in the end, it comes down to how we define intelligence in science. Im in favor of defining the things that you can define narrowly in monday. If you can isolate cognitive intelligence, which you can finish and load the concept of intelligence with things that dont belong to it. In this, thats what we want. Lets focus on cognitive intelligence is, which is by and large with i q test to measure. Interestingly, its distributed in a population in the same way as height. For example, somebody or normal distribution means symmetric values are spread out like this. There are a loss in the middle and fewer at the extremes. Its also called the bell codes. And i q score of 130 or higher is considered highly gifted. Below 70 is considered learning disabled. These extremes account for 2 percent of the population. The how have these scores changed over time . This researcher spent his life study and days how to answer that question. James flynn. He collected and evaluated millions of i. Q test results from dozens of countries recorded over decades. In 1984, he concluded that humans arent getting smarter. Theyre going to observe that starting after 1913 i. Q scores increased by 4 points every 10 years of taxes describe this, thats when the tech talks to them on screen effect. The plan effect based on i q scores, he noted an average li, intelligent person from 1984 would have been considered highly gifted around 1900 on mississippi. Why does it rise in the 1st place . Just imagine ethically people havent changed from quite new smartness. Genes have come along the last 5 years under 10000 years. What im saying, 1000 job ends will become what happened to make the scores climb within just a few decades of we have better nutrition, better medical care, we have more widespread education. But we have to keep in mind that education is really only evolved like this in the last 60 years. She said 5 of her lease and time with learning to read and rise and do mathematics in a rather challenging way. So thats what led to develop your intellectual potential point in 5 to con. Education, you attrition and medicine have all played a part in making people smarter. But theres another factor our working world. In the early 20th century, nearly half of the labor force in developed countries worked in agriculture. They did physical labor. There was no need to engage an abstract thinking. Intelligence researchers asked farmers for example, what fission crows have in common. Non farmers might answer their both animals, but the farmers answered nothing. I can eat a fish, but not a crow. They related everything to their Living Environment and didnt really abstract. Beyond that. Over the course of the 20th century are every day environments became one that prompted us to think more in hypotheticals. Many people no longer fished and instead became more scared with numbers and letters. More people live in cities with more complex social dynamics and more technical applications. That means our brains are also more challenged for one coincide. And if i went, our brains are more challenged in our child who didnt have the lessons they make nor connections. If they have, how many times we have more senses, which is what a mind start greens computational power. Once you take this, can hands all small. And we also knew that brains, that are used more work faster, defend. So mankind in general was soaring to f or Greater Heights of intelligence. I q tests have to be, be calibrated every few years. But in 2004 Norwegian Research has discovered the slit effect no longer held. In fact, i q scores have been dropping slightly since the mid 19 ninetys. That was quite a shock since then researchers have been trying to find out why and theres no easy explanation. In fact, many attempts to rationalize that are problem attic and hotly debated within societies. In 2016 german psychologist kind of and im on survey the International Research community on the causes of decreasing i q scores. Some researchers suggested that less educated immigrants might be dragging down average i q scores. Authors speculated that more intelligent people are likely to have fewer children than less intelligent people. Such hypotheses were reminiscent of the nazi scary of bad genes. When you months out of students, right. So my exam that 80 percent of intelligence is hereditary and 20 percent as environmental. Theyre going to flunk button and keep that one. Well assume that thousands of Team Variations distributed over the entire team to contribute to a persons essential intelligence. The person is also had a good chance to develop his or her intended to win stuff. And of course, that depends a little bit on heredity because what you get from your parents is a source of loss, right . Funds on is on. Contemplate for combs, in 2018 norwegian. Studies show that migration does not play a decisive role in following. I qs. Because scores are also declining within families, for example, between father and son or older and younger sibling. Other studies have shown that heredity is not to blame for our decreasing average intelligence. So what can be causing it . I think can be cool. Pollution is the main fact that we have data from the United Nations showing that a chemical production has increased 300 fold since the 1970s. We find the re wes, in the soil, in the water in the food we eat in the air we breathe. Especially plastic wrappings and things like that, cause metrics. I never went cause much fix with the serious that and to couldnt disruptor. Chemicals in certain products interfere with our hormonal balance. They are linked to the reasons why more and more people are getting diseases like cancer and diabetes. But the thyroid gland is especially affected. And theres both epidemiological and Experimental Evidence to show that firewood hormones. This is necessary for Brain Development. And without thyroid hormones, you have a less efficient brain. So not only are we running our planet into the ground, were bringing our intelligence down with it. There are so many Technical Solutions that are increasing, you know, mercury, which is found in fish to fluoride plastics. Bpa, etc. So the, the increases exponential, the harm fullness of india chron. Disrupters is undisputed, but whats less clear is how much of an impact they have on our intelligence. Clock is something you could do because these things could greatly impair our intelligence. But whether they really affect middle class people who live in a healthy environment, whether they have that strong of an impact is another question and ok, neros science puts forward another theory for declining i. Q scores isnt done. And when we know from psychological experiments, but humans can process about 11 to 60 bits per 2nd, black and con, thought 11000000. Its our flooding our brains every 2nd. But its not as if in the past, our brains were able to process more stimuli either. Why are we only getting dumber now . Doesnt pull named or digging. So thats the problem of the modern age, the items we have a definite linear increase of interesting information spreading across our online world. And an excellent answer, an object that we have an exponential increase in bold. And bo, is the problem. Events you need if youre no longer able to focus on certain stimuli because youve trained yourself out of that ability by the dc because youre not going to be able to complete these types of exercises. Unintelligence tests effectively against test of gum, if you tend to, but thats how this has been substantiated in a number of different studies. And it was almost an especially convincing one was done at stanford with stanford students for some of the Top Performing students in the united states. And it was 500 students were divided into 3 groups for an intelligence test. The 1st heather smartphones taken away. The 2nd were simply told to turn them off and the 3rd were allowed to have them on. The 3rd group perform the worst. And even the group with their cellphones turned off did significantly worse than the group that didnt have them in the room. So were getting dumber because were too distracted by new media. But isnt that an age old narrative that new technologies are doing us harm . Even when writing was invented, people feared that memory would suffer because wed end up writing everything down. But where would we be without our inventions, thoughts i shall mention for as long as weve been making technical inventions. And people have been trying to source certain tasks for loc 1st, and we try to make the field work easier for ourselves and come to the end. Printing came along so we no longer had to copy out every book and know we no longer have to knew how to navigate from each be because instead we can be guided on longer criminals online and also give on which is all going to you have a special orientation skills are getting much worse because we dont need them anymore as we have all kinds of navigation apps on the iphone. Even as far as spatial orientation is getting worse, isnt really harming our brains to use Navigation Systems or Search Engines. Then goodness to thing, unless we use this and things repeatedly at some points, connections in the brain tend to loosen up until color and learning is all about making connections between stimuli and responses that when said before lights, im going to say up to one point in this plan is that why stimulus triggers another that says and behavior triggers may assume you 9. That is what defines learning. Mean if we stop doing that, it gets low, just total. Okay, so we lose a point or 2 on an i q test. Isnt that just the result of us adapting to our environment . With the invention of electricity, our fire making skills fell by the wayside. Whats the problem . Were freeing up our capacity to make room for new things. Tom sessions, just the so people tend to think its great that theres less children and young people need to know youre going to see a few minutes a trade off and they can be more creative and innovative because they can fill up their brains hard drive differently from them, and this is a fundamental error in thinking about new or biology because we dont have a hard drive in our heads noise, nannan for when we learn something new. The brains hardware and software change. That means functionally, the nerve cells interconnections change. But the brain also changes structurally, and so we all perceive the world very differently. For example, you moms, if you walk through the country side with someone whos studies, thoughts, and youll recognize farmer grasses and trees. And the links between them that someone has that feeling switching dean of human data from the shop to the highest of them. So the decisive argument for why we still need to know a lot is that when we do, we perceive the world star greater nuances. Indeed, we think and go about life and more sophisticated ways when we have more knowledge. And by the way, it actually helps us use Search Engines because we can ask more precise questions. It seems a hardened group. And here we thought we finally moved away from memorization of and destroyed. See if i were a gym and teacher, my students would have to read 6 books. Theres not a single picture and so they wouldnt lose that skill for each type. Given me find one key if i were to geography teacher, id say its great emphasis on reading maps, not cotton is over there. So i think its still important in our day and age and nobody got the, even though we have navigation devices, the guess is from a to b. We have a general understanding of how the world is structured. Theres a lot of confidence that are what countries there are and thinking and how they relate to each other geographically. So is that something and then the, then we can learn to use navigation devices on top of that somewhat. So some of this and its a bit like the pocket calculator, which weve done right. Because the 14 year by the 7th grade, everyone has to understand the number range fall in the home to including the security image. So thats not going back to the days of sleep, visually memorizing things just so we knew them by heart and home. Its about planting seeds of knowledge and our brains that we can use to piece together the world with our eyes wide open, often and all of us. The very sweet chief is speech. The depth is more important than bread. Now we listen to music. Thats as short as 2 minutes. You go to all of us. I think the average listening time on spotify is one and a half minutes. 2 sentences in text. We read hardly have any relative clauses anymore. Theyre getting shorter and shorter. With the vocabulary we use a shrinking, its all too fast. We need to go into more depth and 50 to get the but how do we do that . We can turn back time. It would likely end up a balancing act, integrating new technology in a way that lets us hold on to certain skills the hows the biggest dust center for me, its crucial that we improve our self discipline based on essentially, we need to get the juices flowing in our frontal cortex, which is responsible for all these skills, more often than we currently do. Hi, she go us, we have steps i to who would want to have their frontal cortex and talk for him. It sounds a bit theoretical, but there are actually exercises for it to me, not so hard either. Thats constant, thats what we train our ability to concentrate when we meditate. For example, it could be something simple, 10 minutes and easily incorporate it into our daily routine. Thats the last set, an alarm for 5 minutes and then try to shut out everything in the outside world. I listened to close your eyes and just observe whats going on. And my buddy was comes to mind helps likes to kind i feel my heart beat up and how does my breathing . Why dont i do my muscles feel mine . And can i feel all the way down into my legs before my couch . 10, after 5 minutes, the alarm clock goes off and i press it once im done with my eyes and do the reverse to move on, i simply observe whats happening all around me up. I tried to appreciate all the distracting thoughts for the thing. Thats a good exercise thats been shown to enhance concentration, photos of these, practicing self discipline me
