Why is it so difficult to scientifically refute rumors among middle aged and elderly people?

There are indeed some difficulties in scientifically refuting rumors, such as the issue of genetically modified organisms, which is not very clear in itself. In fact, from a scientific point of view, many scientists believe that many genetically modified organisms are harmless, at least not in experiments. However, the common people do not agree, and the common people are as big as a fight when they hear about the genetically modified, and the common people do not understand, and the experts have no way to give a very categorical conclusion.

So, rumors of genetically modified organisms are flying.

Science itself contains the unknown and things to be verified, not immutable, is the continuous exploration and research of the accumulation and development of empirical and theoretical knowledge, therefore, no one can fully grasp all the knowledge and clear its boundaries, so to explain the rumors very scientifically, is indeed a test of the depth and breadth of the interpreter's knowledge. Just like a child's simple why, sometimes we feel that it is powerless to explain it perfectly.

It can be seen that most of the rumors are related to policies (regulatory changes and formulations, new retirement plans, etc.), medical care (including food safety, pensions, etc.). Middle-aged and elderly people have experienced complex and brutal political turmoil in the social environment of the last century, and this sense of insecurity and distrust has prompted them to tighten the strings of skepticism all the time. Doubt the policy, the current situation, the direction, and especially the future of yourself and your children.

As for the scandals in the entertainment industry, from primary school students to uncles and aunts, they will pay attention to it, and it does not match the conditions of the problem).

From the perspective of cognitive development, the cognition of middle-aged and elderly people is basically fixed, while the cognition of adults is still developing and improving, so the elderly are not as easy to accept new things as adults. On the road of rumors and rumors, it is necessary to constantly update and accept cognition, and from this point of view, the cognitive requirements for middle-aged and elderly people are relatively high.

It is because for middle-aged and elderly people, it is very important to gain a sense of identity and emotional support by communicating with their peers, so perhaps for them, whether it is "plastic rice" or "plastic pellets", if there is any danger, denying it is the easiest way to save trouble.

The rumors about plastic rice are deliberately spread by the rumors in a ** way. It uses the concept of "hearing is false, seeing is believing" in people's hearts, and then calls the particles in ** "rice", which directly evokes strong fear, and emotions can deepen memory and cognitive solidification, making it more difficult to change thinking.

Many aunts and uncles don't even know much about scientific knowledge, and they can only adopt an attitude of "I'd rather believe what they have than what they don't". It can be said that science and superstition are the same for them, as long as it works. Superstition has been proven by experts to be science.

Without the encouragement of the scientists back then, Master Wang Lin would not have called for wind and rain so much.

A well-known domestic science popularization class ** Guoke online for KFC multi-legged multi-winged chicken: The body structure of an organism is determined by genes. DNA is like the chief engineer of a construction project, knowing every detail of the organism and strictly directing the entire construction process.

In the life of an organism, both DNA and chromosomes may be mutated, and those that are not serious will be repaired, and those that are severe will cause lesions, deformities, and even death of the organism. A major change in the number and shape of the limbs must involve many and serious mutations, and the individual has basically no hope of being born out of the shell, and is in the "egg" of fetal death in the early stage of embryonic development. Even if it survives, it is a big problem whether this trait can be stably genetically formed into large-scale farming.

In the same way, artificially modified genes face the same problem. First, a large genetic change in the short term will make it impossible for an individual to survive. Second, with the current technology, it is impossible to do such a precise and perfect fixed-point transformation.

If someone does succeed in creating individuals with multiple wings and legs, they can also make this trait stable and genetically inherited to form a ...... of breeding scaleSuch a major research result has already caused a sensation in the entire scientific community, how could it end up being scolded as a profiteer on the Internet. If you insist on finding a possibility, starting with early embryo transfer, it is theoretically not impossible. When the embryo is about 3 days old, the chick differentiation begins to take shape, and wing buds and leg buds (i.e., future wings and legs) are born, and the head is basically visible.

This is a good time for transplantation: too early, you can't see the prototype, and you can't transplant the desired part in a targeted manner; Too late, the internal structure of the limbs, including skeletal nerves, and other systems, has gradually taken shape, and transplantation is much more difficult.

However, even if the timing is right, there are still difficulties in technology and materials.

At 3 days, the embryo is only about 8 mm long, and the wing and leg buds are only 1 mm long and 1 mm wide. The bud body is small, but it contains important parts of the wing leg that ensure normal development (the epidermal crest at the tip of the bud and the polarized active area at the lower part of the bud), and the slightest defect can lead to deformity. Such a delicate "transplant operation" does provide a possibility in theory, but it will cost a lot of manpower and financial resources, and more problems will be encountered in practice, such as endoskeletal connections and nerve connections at the transplant site.

It is also a hassle to get the winged legs for transplantation. The ideal method is to induce embryonic stem cells, which are cells in a primitive state that have not differentiated into specific tissues and organs, which means that there are many possibilities after induction under appropriate conditions, and the characteristics of totipotency make it have great application prospects. Since it was discovered in the 80s of the last century, people have been committed to the research of stem cells in the prevention of ** diseases, organ transplantation, etc., but so far this technology has not reached the level of cloning entire organs or parts (such as wings) and then implanting them into individuals, but uses cell transplantation as the main means, and it is still immature.

To sum up, it can be seen that the current level of technology is actually difficult to create such an individual as a multi-winged and multi-legged chicken. And these methods that greatly increase costs cannot guarantee success, and I believe that profit-oriented businesses will not adopt them.

At present, there is no definite research at all that shows that lotus leaf and its extract can make people** And the real mechanism of action is to promote intestinal peristalsis and produce diarrhea, which is not fat loss but water reduction Long-term use may lead to dehydration and malnutrition in the body, senna and cassia are also the same thing.

OK. It works pretty well. But not for all fat people.

This kind of thing has to be done slowly, for example, when Darwin first proposed the "Theory of Evolution", he was inevitably scolded by many people, after all, people (referring to the Western world) had accepted the idea of God's creation for many years, and then formed a belief, and the emergence of "The Theory of Evolution" undoubtedly shattered this belief, and more deeply, it touched the interests of religion, and religion will definitely attack it at all costs!

Because the truth is in the hands of a few.

What scientific article gives an example.

Is genetically modified food really harmful? Don't believe it after reading it.

At present, it cannot be proven to be toxic, but it is banned in some countries, and in our country, athletes are forbidden to eat genetically modified foods.

The so-called genetically modified food is the use of biotechnology to transfer the genes of some organisms to other species, and modify the genetic material of organisms to transform them into the goals needed by human beings in terms of traits, nutritional quality, and consumption quality.

According to the different genetically modified foods**, they can be divided into plant-based genetically modified foods, genetically modified yeast vaccines, genetically modified bacteria antibiotics, animal genetically modified foods and microbial genetically modified foods.

The issue of safety[2] brought about by genetically modified foods is a concern; At present, this issue is being hotly debated in many developed countries, mainly in Europe. The controversy has also had an impact on Chinese consumers, and will be more concerned as technology evolves and products are brought to market.

A rumor that tests the feasibility of netizen IQ evolution to mouse IQ.

No way, GMO was proposed by them.

Lack of knowledge and only know how to explain things in terms of experience is a sign of self-righteousness.
