Metropolis and Transportation: For mankind, a ‘city’ was a ‘place’ where people were born, grew up, and eventually died. It was initially difficult for humans to choose a ‘place’ to live. Humans had to follow the fate they were given. However, with the development of transportation and the widespread adoption of online networks, humans have been able to select their own places of residence. Throughout history, humans have only been able to voluntarily choose where they want to live for a short time. Achieving freedom of movement marks a fundamental change in the form and character of cities. The development of transportation has completely transformed our lives. The emergence and evolution of transportation means, such as electric vehicles and high-speed trains, indicate that we are in the middle of a revolution that humanity is experiencing for the first time. If you do not respond to these changes, you will face difficulties. - Joseph’s “just my thoughts”
The social scientist’s method of confirming the facts is first to verify the beta error (Type II error) and then the alpha error (Type I error) before accepting the hypothesis as true. In other words, if the probability is less than 5% after focusing on the likelihood of accepting a false hypothesis as true (Type II error), then we risk rejecting a true hypothesis (Type I error) as false. It’s a conservative position that new information will be accepted only when the probability of being wrong is very small. This verification method is helpful if you don’t want to be swayed by conspiracy theories. - Joseph’s “just my thoughts”
