As I wrote in December 2019, “Think Scientifically” was one of my five key takeaways from 2019. Of late, it has become increasingly obvious to me that there is great value in scientific thinking — and, not doing so is unusually dangerous.

To think scientifically, I believe, is to think independently, to be grounded in facts and free of preconceived notions. Scientific thinking seeks truth, not opinions. It welcomes different ideas, new ideas. It also encompasses the willingness to acknowledge that “I can be wrong.”

In the evening of January 20, 2020, China’s respiratory expert Zhong Nanshan confirmed and announced to the public that the virus had passed from person-to-person. I was in Beijing that Monday evening.

By 9pm that day, when I looked out onto the street, many citizens already had surgical masks on. By the next day, as I was travelling through China on a high-speed train, somewhere between 20% to 50% of people I saw started wearing masks.

Within three days, on January 23, Wuhan was locked down. In the following few days, Chinese cities started requiring citizens to wear surgical masks and implementing other types of social distancing measures. For example, on January 26, 2020, Suzhou announced that all passengers using the city’s subway system must wear surgical masks.

This is a year-end personal reflection piece. The following five takeaways of mine are inherently backward-looking, but hopefully by examining the past I become more informed going forward.

#1 Think Independently

We giggle when watching lemmings do all kinds of funny things in a group together. But we are not that different — we humans are just as social species as lemmings are. As a general observation, we like people who are like us — a tendency which builds an intellectual echo chamber that confines and reinforces our thinking, making it less independent.

Thomas Friedman made an interesting argument in his book The World Is Flat: in a globalized world, historical and geographic divisions are becoming increasingly irrelevant.

Through my experiences, however, I think the opposite is happening — in a globalized world where people from different cultures interact with each other, historical and geographic divisions are increasingly visible and relevant.  In order to make better decisions in a globalized world, local knowledge becomes more valuable than ever before!
