People who lean left politically reported an increase in trust in scientists during the COVID-19 pandemic, while those who lean right politically reported much lower levels of trust in scientists. This polarization around scientific issues – from COVID-19 to climate change to evolution – is at its peak since surveys started tracking this question over 50 years ago.
Surveys reveal that people with more education are more ideologically liberal. And academia has been gradually turning left over the past 40 years. Scientists – the people who produce scientific knowledge – are widely perceived to be on the opposite side of the political spectrum from those who trust science the least. This disparity poses a challenge when communicating important science to the public.
In a recent study, science historian Naomi Oreskes, environmental social scientist Viktoria Cologna, literary critic Charlie Tyson and I leveraged public data sets to explore the dynamics of scientists’ political leanings. Our analysis of individual political donations confirms that the vast majority of scientists who contribute have supported Democratic candidates. But we contend that this fact doesn’t need to short-circuit effective science communication to the public.
Digging into individuals’ political donations
In the United States, all donations to political parties and campaigns must be reported to the Federal Election Committee. That information is published by the FEC on its website, along with the donation amount and date; the donor’s name, address and occupation; and the recipient’s party affiliation. This data allowed us to examine millions of transactions made in the past 40 years.
In our study, we examined researchers in academia, specifically people with titles like “professor,” “faculty,” “scientist” and “lecturer,” as well as scientists in the energy sector. We conducted this analysis by identifying 100,000 scientists based on their self-reported occupation and cross-referencing them with the Elsevier’s Scopus database, which contains information on researchers and their scientific publications. The findings of our study indicate a gradual shift away from the Republican Party among American researchers, both in academia and the industry.
Overall support of the Republican Party, in terms of individual donations from the general public, has slid down over the past 40 years. But this trend is much steeper for scientists and academics than for the overall U.S. population. By 2022, it was hard to find an academic supporting the Republican Party financially, even at Christian colleges and universities. The trend also persists across academic disciplines.
Notably, scientists working at fossil fuel companies have also become more liberal, while their management has remained conservative, based on both groups’ political donations. We suspect this buildup of political polarization within companies may at some point…
