Taking stock of those magical "pseudo-technology" products, in recent years, many businesses exaggerate the efficacy of products under the guise of technology in order to obtain higher profits. We call these products marketed with high-tech concepts "pseudo-technology products". Be careful when you see products that exaggerate a certain function and wear a technological coat in the future.
Take stock of those magical "pseudo-technology" products. 1 The development of technology has undoubtedly brought us many good products and made our life more convenient and rich. However, it can also be seen that in recent years, many businesses exaggerate the efficacy of products under the guise of technology in order to obtain higher profits.
These high-tech products are called "pseudo-high-tech products", which are used by some businesses to fool consumers by boasting that their products have magical effects with the help of "high-tech" labels. Many people may think that these pseudo-technology products are far away from themselves because they have clear judgment. However, sometimes, we may believe that some products do have certain effects because of our own needs, but the results are deceptive. Below, let's take stock of some fake technology products, see if we have paid IQ tax for them, and remind everyone not to be confused by the propaganda of the merchants.
The picture above shows a product that has suddenly become popular recently. Its name is "Cell Phone Signal Enhancement Sticker". Although we have now entered the 5G era, the signal receiving ability of some mobile phones is somewhat unsatisfactory, and the signal of mobile phones in underground parking lots, subways and other places is very poor. So some merchants aimed at this pain point of users and launched this product, claiming that as long as they put a patch on the back of the mobile phone near the signal receiver, they can get stronger signals and even surf the Internet smoothly in some places with weak signals. A reporter asked the merchant what the principle of this product is? Some merchants replied that "as long as the back cover of the mobile phone is not glass, it can be enhanced, and the signal of 1 grid can generally be enhanced to 3 grids after being affixed". The principle is that stickers (chips) can increase the wavelength of mobile phones.
Is this statement credible? To this end, some experts have done experiments specifically for this product. The results show that, in terms of material and structure, the most advanced signal enhancement sticker claimed by merchants is to coat an aluminum film on a plastic sheet and print a material similar to magnetic ink on the aluminum film. However, the statement that the signal enhancement sticker enhances the receiving range of the signal by lengthening the wavelength of the signal received by the built-in antenna of the mobile phone is unreasonable in principle, because the wavelength cannot be "lengthened" in real life; Secondly, it takes energy to amplify anything. Stickers are "passive antennas" and cannot provide energy for effectively amplifying signals. Therefore, the "mobile phone signal enhancement sticker" is a useless product covered with a technological coat, and those who want to enhance the signal by this way should be awake.
This product in the above picture should be familiar to everyone. It is not an ordinary rice cooker, but a sugar-free rice cooker claimed by the merchants, which is undoubtedly very attractive for diabetics or dieters.
Let's take a look at its principle first: unlike the solid bottom lining of ordinary rice cookers, the bottom of the inner liner of sugar-removing rice cookers is covered with water leakage holes, and a box for collecting rice soup is added below. Ordinary rice cookers steam rice with rice and water. When the water is dry, the rice will be cooked. In addition to sugar, the rice cooker will filter out the rice soup when steaming rice, steam it until it is half cooked, and then steam the remaining rice, so that the sugar content of rice will drop a lot. Some merchants can effectively reduce the sugar content in rice by 70%. But is this really the case? In order to verify the actual hypoglycemic effect of sugar-free rice cookers, CCTV invited 15 volunteers to eat and measure their blood sugar. The results showed that, although the peak blood sugar of volunteers who ate sugar-free rice cooker was slightly lower than that of normal rice, there was no significant difference in medical statistics, that is, there was no hypoglycemic effect. Therefore, sugar-free rice cookers can indeed reduce some sugar in rice, but they are far from as effective as advertised, and relying on this gimmick, the prices of many sugar-free rice cookers are often several times that of ordinary rice cookers.
Below, let's take a look at some outrageous examples of "pseudo-technology products". In recent years, graphene, as the "king of new materials", is famous and full of science and technology, so some merchants seize this hype and borrow it in some health care products or clothing products, claiming to have antibacterial and bacteriostatic effects, moisture absorption and perspiration. You should know that graphene has good thermal conductivity, but it absorbs heat quickly and dissipates heat quickly. The most important thing is that graphene materials are not easy to obtain and the price is very expensive. Even if you make a completely single-layer pure graphene underwear, the cost will be at least several hundred million, and few people can afford it.
In addition to graphene materials, there are many businesses that have made articles about quantum that few people understand, such as "quantum water cups" and "quantum glasses", and even ordinary insoles use "quantum energy", which claims to have certain health care effects. But this is deceptive, because quantum technology is still in the research stage, and it is still a long time before it is applied to civilian products.
To sum up, as long as these pseudo-technology products are carefully understood, they can all find loopholes in publicity, but we are often stimulated by our own needs, easily confused by businesses, and finally can only be rewarded with IQ tax. Therefore, in the future, we should be careful to see products that exaggerate a certain function and wear a technological coat before deciding whether to buy them.
Have you ever come across such fake technology products in the shopping process?
Take stock of those magical "pseudo-technology" products, 2 "dark matter" shampoos to prevent hair loss, 2 "graphene" warm clothes to repair relaxation, and "quantum" medical devices to cure all diseases ... Now health care products labeled "high-tech" appear frequently. With the help of high-tech labels, some unscrupulous merchants boast that their products have magical effects, fool consumers and seriously damage their legitimate rights and interests. A few days ago, a survey conducted by the Social Investigation Center of China Youth Daily showed that 8 1.3% of the respondents felt that there were many fake technology products, and 86.3% of the respondents said that someone around them had been fooled by fake technology products.
Perhaps it is an opportunity for consumption upgrading. In recent years, all kinds of new products under the guise of high technology have emerged one after another, and quickly occupied the major advertising platforms. Whether it is to flaunt a cure for all diseases, or to use new concepts such as dark matter and quantum, it is not difficult to see through the mystery behind such products as long as you have some scientific common sense and even search relevant information online. But this anti-science product under the banner of science and technology has many fans. In this regard, there are many voices calling for strengthening popular science, but the popularity of pseudo-technology products needs to be viewed from a deeper level.
Whether it is trusting in "artifacts" or generally accepting black technology, the essence is that there is a problem with scientific and cultural cognition. Li Daguang, a professor at China Academy of Sciences, once pointed out: "In recent years, the people aged 18 to 24 in China have the highest level of scientific literacy, but the proportion of this group in the whole national group is very low, and our overall level is really not high. With the growth of age, the scientific literacy level of the public in China has dropped sharply, which is in great contrast with European and American countries and Japan. The distribution of scientific literacy in Europe and America is relatively even, with the exception of Japan. The older you are, the higher your scientific literacy is. "
With the increase of age, the level of scientific literacy declines, which seems not difficult to explain in the conventional sense. For example, with the growth of age, people's social circle narrows, information receiving channels decrease, and it is easy to be out of touch with the times, and it is easier to be confused by pseudo-science and pseudo-technology. The "rumor of parents' circle of friends" that is being ridiculed at present is a typical example. At the same time, in the era of mobile Internet, all kinds of interest-driven pseudo-popular science confuse the true and the false, making it easy for people who used to be in a state of closed information to lose their judgment and discrimination.
Li Daguang believes that to improve scientific literacy, we can't rely entirely on popular science, which belongs to informal education. What can really improve citizens' scientific literacy at this stage is formal education in schools. Unfortunately, many people's study habits are not formed in the formal education stage, and many people's motivation to acquire knowledge is often to cope with teachers and exams, not to improve their personal quality. It is in this respect that there is still a gap between us and foreign countries. As a result, people still have the ability to identify pseudoscience when they are young, because they are educated and have a lot of information. Once they get older, their ability to accept information weakens, and the weak side of scientific literacy and scientific cognition is exposed.
In daily life, many people show the cognitive misunderstanding that they don't believe in common sense but are keen on believing in miracles, which can also reflect our lack of scientific and cultural cognition. Respect for common sense, to put it bluntly, is to have enough understanding of general scientific laws and respect for scientific spirit. Too much belief in miracles is contrary to the scientific spirit, but isomorphic to the pursuit of metaphysics, strange gods and masters. However, not everyone can meet experts. Nowadays, pseudo-technology advertisements are almost everywhere, and it is easy to be fooled.
Pseudo-scientific products with magical functions have magnified the defects of society in scientific literacy and concept. In this regard, in addition to strengthening daily popular science, it is more urgent to strengthen the guidance of scientific culture and concepts in conventional education.
