Social interactions between humans have established an extremely wide variety of values, social norms, and rituals, which together under-gird human society (Wikipedia) --- Mass fear will destroy that.
Emotion has a significant influence on, or can even be said to control, human behavior (Wikipedia).
Humans are highly social beings and tend to live in large complex social groups. More than any other creature, humans are capable of using systems of communication for self-expression, the exchange of ideas, and organization, and as such have created complex social structures composed of many cooperating and competing groups. Human groups range from the size of families to nations. Social interactions between humans have established an extremely wide variety of values, social norms, and rituals, which together form the basis of human society (Wikipedia) --- Mass fear will destroy this.
In Herbert Kelmen's work on dehumanization, humanness has two features: "identity" (i.e., a perception of the person "as an individual, independent and distinguishable from others, capable of making choices") and "community" (i.e., a perception of the person as "part of an interconnected network of individuals who care for each other"). When a target's agency and community embeddedness are denied, they no longer elicit compassion or other moral responses, and may suffer violence as a result (Wikipedia) --- Fear will lead to this denial.
Really, fear is the only thing to fear....because fear attracts that which is feared.
"There are times when fear is good, It must keep it's watchful place at the heart's controls" (Aeschylus)
I think if this social distancing goes on for too long, it will have huge repercussions. In my opinion, huger than the virus as it is now.
“Avoiding danger is no safer in the long run than outright exposure." (Helen Keller) --- Fear attracts what is feared.
“The only thing we have to fear is fear itself” (Franklin D. Roosevelt)
