Keywords

💡Skepticism

Skepticism in this context refers to a questioning attitude or doubt about the validity of information, particularly in the digital age where misinformation can be rampant. It is central to the video's theme as the speaker expresses growing doubt about the reliability of online news and the importance of critically evaluating data. An example from the script is the speaker's increasing skepticism as they consume more online news and blog posts.

💡Credibility

Credibility is the quality of being trustworthy or reliable, which is highlighted in the video as a key factor when evaluating information, especially data presented online. The speaker mentions that people often ask for data to support claims, indicating the demand for credible evidence. The term is used to emphasize the need for verifying the trustworthiness of the information we encounter.

💡Statistical Data

Statistical data refers to numerical information that has been collected and analyzed to represent certain facts or trends. In the video, the speaker appreciates looking at statistical data from reputable sources as a way to form educated opinions. Examples given include the average tenure of employees in Japan and the U.S., which are used to illustrate differences in job stability between the two countries.

💡Misinterpretation

Misinterpretation is the act of understanding something incorrectly or in a way that is not intended by the original source. The video discusses how even when presented with the same data, different people may draw different conclusions, which can lead to misinterpretations. The speaker warns against the potential for misreading data and the consequences of forming incorrect beliefs.

💡Correlation and Causation

The terms 'correlation' and 'causation' are used in the script to illustrate the difference between two statistical relationships. Correlation indicates a statistical association between two variables, while causation implies a direct cause-and-effect relationship. The speaker uses the example of ice cream sales and drowning incidents to clarify that correlation does not imply causation, a critical point in understanding data correctly.

💡Tobacco and Cancer

Tobacco and cancer are mentioned in the video to discuss the relationship between smoking and the increased risk of lung cancer. The speaker points out that despite a decrease in smoking rates over the past 50 years in Japan, lung cancer rates are rising, indicating that the relationship between smoking and cancer is more complex than simple statistical trends might suggest.

💡Aging Population

The aging population refers to a demographic trend where the proportion of older individuals in a population is increasing. In the video, the speaker suggests that the rise in lung cancer cases in Japan may be related to an aging population, as those who smoked in the past are now experiencing the health consequences, highlighting the importance of considering broader societal factors when interpreting data.

💡Data Misreading

Data misreading is the act of incorrectly interpreting or understanding data. The video emphasizes the danger of misreading data, as it can lead to the acceptance of false conclusions. The speaker warns that even with accurate data, incorrect interpretations can lead to misguided beliefs or actions.

💡Critical Thinking

Critical thinking is the process of analyzing and evaluating information in a reasoned and logical manner. The video concludes with the importance of critical thinking, as the speaker reflects on the need to think for oneself, regardless of the amount of information and data available. It is a call to action for viewers to engage in independent thought rather than blindly accepting information.

💡Information Overload

Information overload refers to the difficulty in understanding or making decisions due to the excessive amount of information available. The speaker mentions staying inside and consuming internet news and YouTube, which could imply an experience of information overload, a common challenge in the digital age that can contribute to skepticism and the need for critical thinking.

💡Reputable Research

Reputable research denotes scholarly work or data that is produced by trustworthy and well-regarded sources. The video script mentions the preference for statistical data released by financial institutions or reputable research organizations, which underscores the importance of source credibility in ensuring the reliability of the information being analyzed.

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.
