WASHINGTON -- Republicans' faith in science is falling as Democrats rely on it even more, with a trust gap in science and medicine widening substantially during the covid-19 pandemic, new survey data shows.
It's the largest gap in nearly five decades of polling by the General Social Survey, a widely respected trend survey conducted by NORC at the University of Chicago that has been measuring confidence in institutions since 1972.
That is unsurprising to more than a dozen scientists reached for comment by The Associated Press, but it concerns many of them.
"We are living at a time when people would rather put urine or cleaning chemicals in their body than scientifically vetted vaccines," University of Georgia meteorology professor Marshall Shepherd told the AP in an email. "That is a clear convergence of fear, lack of critical thinking, confirmation bias and political tribalism."
Science used to be something all Americans would get behind, Rice University historian Douglas Brinkley said.
"But we now see it falling prey to the great partisan divide," he said. "The world of science should be a meeting house where right and left can agree on data. Instead, it's becoming a sharp razor's edge of conflict."

Overall, 48% of Americans say they have "a great deal" of confidence in the scientific community, the 2021 General Social Survey data shows.
Sixty-four percent of Democrats say that, compared with roughly half as many Republicans, 34%. The gap was much smaller in 2018, when 51% of Democrats and 42% of Republicans had high confidence.
The poll also found a gap emerging on confidence in medicine, driven primarily by increasing confidence among Democrats. Forty-five percent of Democrats said they had a great deal of confidence in medicine, compared with 34% of Republicans.
The deepening polarization was not evident for other institutions asked about on the poll, according to Jennifer Benz, deputy director of The Associated Press-NORC Center for Public Affairs Research.
"It's certainly plausible that this is a result of how politicized the pandemic became in the months between when it emerged and when the survey ran," Benz said. "It is definitely a stark change for these particular trends on confidence in scientific leaders and leaders in medicine, to see this degree of polarization."
The data suggest Republicans and Democrats are following the cues of their leaders, said Anthony Leiserowitz, director of the Yale Program on Climate Change Communication.
"We've seen so much criticism [and worse] leveled at medical experts since the beginning of the pandemic from the former president, other Republican leaders and the conservative media, and just the opposite from the current president, Democratic leaders, and the mainstream and liberal media," Leiserowitz told the AP in an email.
Scientists and policy makers tend to be conservative -- not politically but in terms of being cautious and wary of risk -- pushing safety, masks and vaccines while "Republicans as a group value individual liberty," Marcia McNutt, president of the National Academy of Sciences, which was set up by President Abraham Lincoln to offer the federal government expert advice.
"So no wonder that Republicans are less supportive of the scientifically conservative decisions in the face of uncertainty," she told the AP in an email.
The consequence of declining trust in the scientific community among Republicans is clear: AP-NORC polling shows Republicans continue to be less likely than Democrats to be vaccinated.
