A movie that shows 'Why science lie?' In one shot



Science is an integral part of modern society, as is the news about the new coronavirus, but many are not professionally educated scientists for years, so they convey scientific things. Articles and movies will more or less make a 'lie' that simplifies the facts.

Kurzgesagt, a YouTube channel that has produced many scientific educational movies, explained the need for science to lie and its implications.

... And We'll Do it Again-YouTube


The movie begins with a shocking confession that 'Kurzgesagt is lying in all video works, including this one.'



The 'lie' here is not a factless falsehood, but a kind of 'lie when explaining to a child'.



For example, when I was a kid, many people remember being shown the following illustrations and being taught that 'our earth is orbiting the sun with many friends.'



However, in reality, the sun and the planets of the solar system are completely different in size, and the distance between the planets is very long, so these illustrations can be said to be 'lie' in a sense.



Science often uses such tricks so that you can develop a scientific mindset without having to study hard for years.



Only a few hundred years ago, it was not impossible for a single intellectual to be familiar with the expertise of all disciplines. However, in today's world of exponentially increasing information, trying to know all areas is a waste of effort.



Therefore, it is necessary to have a process of expressing things in an easy-to-understand manner with 'parables' that capture the essence of things as much as possible. One of the typical examples is the molecule. At school, molecules are described by balls thus tied together with several arms.



However, the actual molecule is a cloud-like mass of charge-bonded atoms that move around while constantly vibrating.



These simplifications not only facilitate the understanding of the general public, but are also beneficial to the professionals themselves. For example, when a chemist explains a chemical bond to an expert in another field, the following 'untrue electron shell model' is used.



However, the human brain has not evolved to understand science, nor has this world been created to make humans understand it. Therefore, in some cases, excessive simplification can be a problem.



It is true that research on cancer that attracts people's attention leads to the discovery of new treatments, and research on food helps to develop healthy foods.



However, if you can't find a cure for cancer after all, or if your diet doesn't go well with diet foods, your confidence in science can be undermined.



Conversely, when people get caught up in over-the-top stories and over-the-top simplifications, facts that are supposed to be complicated are distorted, leading to false reassurance and overconfidence in one's scientific knowledge.



One of the reasons for the surge in people who are not experts but deny vaccines and climate change is the lack of communication between science and people. This problem has a serious negative impact not only on individuals but also on society.



So, with millions of viewers, Kurzgesagt starts by reading science articles, peruses books and peer-reviewed dissertations, collects primary sources such as expert interviews, and makes their own movies. It is said that the facts simplified for this purpose are summarized in a document with references.



Still, in order to put together complicated things into a video of about 10 minutes, the process of selecting information and omitting the end nodes of branches and leaves is absolutely necessary. This is the true meaning of the confession at the beginning, 'I lie in every video work.'



Kurzgesagt said of the future of science-explaining movie production: 'What we want to do most is to inspire people and arouse their curiosity about science and the wonderful world we live in. It's fun to learn. Not only, but it's great if you have the right story. It's ultimately about reading a book, studying more seriously at school or college, or taking an interest in the scientific field yourself. I hope it helps you learn, and I hope you enjoy our videos even after learning that we have the 'lie' of simplification. '
