My American senior. Please understand that I am not good at English. I speak English at the elementary school level in the United States. As you say, I don't know the topic of Cliff's conversation.
In Korea, many people take the contents of researchers like Cliff and publicize it as if it is true.

The world is full of fake news and information, but I don't know what to believe. As you say, I would have to separate the wheat from the chaff, but I still lack power.

Looking at your writing, I am learning how to share wheat and chaff.
