"Four years ago, the country was brought to its knees by a world-historic disaster. COVID-19 hospitalized nearly 7 million Americans and killed more than a million; it’s still killing hundreds each week. It shut down schools and forced people into social isolation. Almost overnight, most of the country was thrown into a state of high anxiety—then, soon enough, grief and mourning. But the country has not come together to sufficiently acknowledge the tragedy it endured. As clinical psychiatrists, we see the effects of such emotional turmoil every day, and we know that when it’s not properly processed, it can result in a general sense of unhappiness and anger—exactly the negative emotional state that might lead a nation to misperceive its fortunes. The pressure to simply move on from the horrors of 2020 is strong. Who wouldn’t love to awaken from that nightmare and pretend it never happened? Besides, humans have a knack for sanitizing our most painful memories. In a 2009 study, participants did a remarkably poor job of remembering how they felt in the days after the 9/11 attacks, likely because those memories were filtered through their current emotional state. Likewise, a study published in Nature last year found that people’s recall of the severity of the 2020 COVID threat was biased by their attitudes toward vaccines months or years later."
