Transcripts
Good morning. It's Yusuke. This is near Chiba Station.
It rained two days in a row until yesterday, so I didn't walk outside much.
So I'm taking a walk today for the first time in a while.
I didn't walk outside much for two days, so I stayed inside and watched Internet news and YouTube.
But online news can contain false information, so
the more I read news and blog posts, the more skeptical I become.
Recently, on online debate programs or in places to discuss something, some people say something like, "Do you have any data on that?"
They're saying, show the credibility of what you're saying with some data.
But if you only look at the information and data you gather on the Internet, I think it is possible to draw wrong conclusions.
But I just like to look at some statistical data.
Data released by financial institutions or reputable research organizations.
For example, according to Japan's Minister of Health, Labor and Welfare, in Japan, the average time between when we start working for a company and when we quit is 13 years.
In the U.S., they leave their jobs after an average of 4 years.
The percentage of those who quit after less than one year is 8.0% in Japan, and 23% in the U.S.
Just looking at these numbers, we can think of many things.
In Japan, there may be some advantages to working for the same company for a long time, or
there may be circumstances that prevent you from working in the U.S. for a longer period of time,
it's fun to be able to guess a lot just by looking at those numbers.
But even if you look at the same data, what you feel is very different from person to person.
It's fun to learn interesting facts about these statistics if we can understand them correctly.
But if you misread them, you may mistake what is not true for fact.
The relationship between tobacco and cancer is a good example.
They say smoking increases your chances of getting lung cancer, right?
50 years ago, more than 50% of people in Japan smoked.
Right now, about 15% of people in Japan smoke.
Over the last 50 years, the number of smokers has decreased from 50% to 15%.
Of course, you would think that fewer people would be getting lung cancer, right?
But in Japan, lung cancer patients are on the rise.
More people are getting lung cancer than 50 years ago.
Looking at this data alone, there must be people who think that there is no relationship between smoking and lung cancer.
But the fact is more complicated than that, people who smoked 40, 50 years ago are getting cancer now, or
it's related to Japan's aging population, or
there are things hidden there that you can't tell from that data alone.
The most obvious example is: It is said that on days when ice cream sells well, many people drown at sea.
In fact, on days when ice cream sells well, many people drown in the ocean.
But in reality, those are just temperature-related, and there's no direct relationship between the number of ice cream sales and the number of people drowning in the ocean.
Well... as for this ice cream story, most people find that the two are not related. But
for more complicated data, some people come to the wrong conclusion when they think only on the basis of those data.
If you have the right information but read it the wrong way, you may create and believe your own conclusions that are different from the facts.
Or someone could create a false conclusion based on correct data, and you could be fooled by that.
No matter how much information and data you gather, in the end you need to be able to think for yourself.
Well... that's common sense, but I felt something like that again.
OK so, this is the end of today's video. See you.
