For millennia, societies have faced destructive epidemics that caused a major loss of life. Although the germs that cause epidemics change over time, and people may pretend humanity has too, responses to epidemics show startling similarities across centuries. During Justinian's Plague, 40% of Constantinople's population perished. When the plague of Athens struck, it took out up to 30% of the city. And when the Black Death swept Europe in the 14th century, it ended the lives of millions, with population losses of over 50% in some areas. Even epidemics with lower mortality rates cause major disruptions, like the Spanish flu of 1918. But regardless of era or disease, people have shown many of the same responses: flee from the source of the danger, look for a scapegoat, propagate pseudoscientific cures, and question scientific authority.
In a time of crisis all bets are off; we fall into the most primal fears and patterns. And though people will do what they can to save themselves, not all behaviors are bad. Some may even better prepare humanity for future epidemics and crises.
