(CNN)The US response to coronavirus has been consistently inconsistent. It''s also uniquely American.


There are no national guidelines and no organized efforts to reopen the country beyond what measures states have taken. Public health officials say one thing while governors say another and President Donald Trump says something else entirely. We Americans are left to make up our own minds.


"It''s always been the orientation of America on balance, compared to other countries, to put a priority on individual freedom and liberty," says Andrea Campbell, a professor of political science at the Massachusetts Institute of Technology who studies the intersection of politics and public health.


It''s the ideal that birthed the US, when colonists split from the British monarchy to establish their own nation. It powered pioneers who ventured west to the frontier, where they settled their own towns and made their own rules. It''s in our DNA.


It''s also sown deep political divides, distrust of centralized authority and even skepticism of science. And it''s informing the country''s unruly response to this pandemic.


It''s reinforcing our partisan politics


Republicans and Democrats interpret individualism differently, and those divides are more pronounced than ever in our deeply polarized political climate.


Now, even the pandemic is refracted through an ideological lens.


"Nothing binds groups together like facing a common enemy," says Ann Keller, a University of California-Berkeley associate professor who studies pandemic responses. "But we''re still treating members of the other party as the enemy rather than the virus."


His supporters are listening. So are those who detest him. Both hear what they want to.


In an April CNN poll, a plurality of Americans (55%) said the federal government has done a poor job of preventing the spread of the coronavirus. But 80% of Republicans said the federal government has done a good job, and 85% of Democrats said the opposite.


Questions over reopening are fraught, too. More than half of Republicans in the same poll said they feel comfortable returning to their normal routines. Just a quarter of Democrats said the same.


In this unsettling time, even the wearing of a face mask has become a political statement.


It''s possible for even a deeply divided America to overcome party divides. Keller points to President George W. Bush, whose popularity soared from the low 50s to 90% in the days after the terror attacks of September 11, 2001. Terrorism was a national threat, and there was no question of that threat''s legitimacy.


But the coronavirus isn''t being viewed in the same way.


It''s feeding anger toward state governments


Americans have resented centralized power since they dumped tea in Boston Harbor. Many still bristle when they think politicians are stepping on their freedoms -- even in a pandemic.


Because there was never a nationwide stay-at-home order and the virus didn''t unfold evenly across the country, some states took decisive early action, which might''ve helped them avoid potentially devastating outcomes, says David Rosner, a sociomedical historian at Columbia University''s Mailman School of Public Health.


"The fact that different states at different moments had the ability to shape their own reaction was a good thing," Rosner says. "They didn''t depend on a federal government that had no coherent activity, actions or ability to shape a federal response to illness and disease."

“事实上,不同的州在不同的时刻有能力决定自己的应对,这是一件好事。” 罗斯纳说:“他们并不依赖于一个活动、行动或能力没有一致性,无法制定对病情和疾病的应对的联邦政府。”

Limited government is a conservative ideal, which may explain why Trump has handed the reins back to the states.


Without national guidelines and an organized response, states, counties and residents have been left to make their own choices, either in line with or against public health advice.


For weeks, protesters have led rallies to reopen their states'' economies. And instead of directing their ire toward the federal government, they''re targeting governors responsible for the stay-at-home orders.


Republican governors like Maryland''s Larry Hogan and Democrats like Gretchen Whitmer of Michigan have stoked the rage of residents who accuse them of stifling their rights to reopen their small business or go to a hair stylist.


But Americans have obeyed and even welcomed government intervention in past crises, Rosner notes. In the 1930s President Franklin Delano Roosevelt grew the federal government''s powers permanently with New Deal programs that helped pull the country out of the Great Depression.


"We''re not seeing Americans pull together in the way we thought they would, like the sacrifices made in World War II," Keller says. "People saw it as part of being an American, and people found meaning in those individual sacrifices. I think it''s striking that we''re not seeing that."

“我们没有看到美国人像我们想象的那样团结在一起,就像二战中做出的牺牲一样。” 凯勒说:“当时人们把它看作是身为美国人的责任,人们从这些个人的牺牲中找到了意义。我认为我们现在没能看到这一切是令人震惊的。”

It''s reflecting our distrust of science


The same may not be true if and when a coronavirus vaccine becomes available.


That''s because of a meager but vocal (and growing) mistrust in science, punctuated by the climate crisis and the anti-vaccine movement. People in these groups view scientific experts as dictatorial figures whose decisions strip people of their freedoms to choose what''s best for them.


The most divisive scientific topics of our time, climate change and vaccination, are well-studied. The novel coronavirus is not. It emerged at the tail end of 2019, and we are still learning more about its transmission.


It''s telling, too, that the CDC has taken a backseat in handling the crisis, Keller says. It started when the CDC''s initial coronavirus tests failed and delayed the response for weeks. And CDC director Dr. Robert Redfield has been much less visible than Dr. Anthony Fauci, who heads the National Institute of Allergy and Infectious Diseases.


It may have weakened the White House''s confidence in the health agency, Keller says.


It''s fortifying our belief that America knows best

它强化了我们的信念 ,即美国最懂

We haven''t followed any countries'' leads. That''s the American way — our individualistic identity is a global one, too.


"Americans have this very strong sense of American exceptionalism -- that the US is different than other countries and superior in many ways," Campbell says.


South Korea''s model worked. The US lagged behind it.


It''s leading our cost-benefit approach to the virus


So, when weighing the tradeoffs of social distancing, many Americans make their decision with some capitalistic cost-benefit analysis. The cost is life as we know it -- going to restaurants, shopping, visiting friends, working at an office. The benefit is our health, and the health of loved ones and strangers.


Making sacrifices to help a stranger may be a hard sell for some.


"The issue with the coronavirus is that it''s not very visible," Keller says. "You don''t know who you''re protecting, who''s avoided getting sick from your actions. That''s a big ask of people, especially when it appears that not everyone is doing it or that the criteria seems to be different in different parts of the country."


But people will remember what they lost by making those sacrifices.


More than 89,000 Americans have died from coronavirus. But more than 36 million have filed for unemployment. If lawmakers rely on that ratio alone to decide whether to reopen, the decision is already made.


But we can still fight this together


If the virus is with us for many more months, we may move toward a united response, Keller says.


Not every American subscribes to the historic definition of individualism that prizes oneself over the communal good. Some are exercising their individual will to stay home if they can, in line with public health advice. And those of us who can''t stay home are largely following the safest protocols for how to act in the workplace.


Americans don''t want to live in fear of an invisible enemy, and we don''t want our country to crumble. But to beat this crisis, we may need to balance individual liberties with collective sacrifice. That doesn''t come naturally to us, but we can do it. We''ve done it before.
