Take, for example, the Availability Heuristic, which points out that "the easier it is to think of and the more intensely mentally accessible situations (recent, or frequently seen, impressive) situations, people tend to I think there is a high chance of this happening.” For example, people are closely watching the number of confirmed cases and deaths of the new coronavirus these days.

Even though the fatality rate of influenza is high, the new coronavirus is still more feared in everyone's heart. Because, if you swipe your phone twice, you will see a bunch of related news.
We are also more inclined to think of the epidemic as more Image Manipulation Service terrifying in our minds, and to stage disaster movies like "The Spread of the Territory" and "Corpse Train" in our minds. In the face of the unknown, the imagination of infinite expansion is actually useless. Understanding the possible thinking biases caused by "Availability Gestures" does not mean that we do not need to be vigilant.
