As public debates continue over a range of science-related topics, including climate change and the safety of eating genetically modified (GM) foods, Americans are largely skeptical about the degree to which scientists understand these two issues, whether there is scientific consensus on them, and the influences on scientists\u2019 research.<\/p>\n\n

Recent Pew Research Center studies have examined in depth what the public thinks about scientists and their research related to climate change<\/a> and GM foods<\/a>. These surveys found that public views of scientific experts in these two areas spring from different factors: When people think about climate scientists, their views are strongly divided by politics. When they think about scientists dealing with GM foods, their views are more closely tied to their level of science knowledge than to their politics.<\/p>\n\n

<\/a><\/figure>\n\n

Americans are largely skeptical of scientific understanding about both the causes of climate change and the effects of GM foods. Some 28% of Americans think climate scientists understand the causes of global climate change \u201cvery well\u201d; 19% think scientists understand the health effects of GM foods \u201cvery well.\u201d<\/p>\n\n

<\/p>\n\n

In the public eye, there is considerable disagreement among scientists in both areas. Just 27% of Americans say that almost all climate scientists agree human behavior is mostly responsible for climate change. This perception is at odds with a 2013 report from the Intergovernmental Panel on Climate Change<\/a>, which assessed more than 9,000 scientific publications and concluded: \u201cThe science now shows with 95% certainty that human activity is the dominant cause of observed warming since the mid-20th century.\u201d<\/p>\n\n

Similarly, 14% of U.S. adults say that almost all scientists agree GM foods are safe to eat, and another 28% say more than half of scientists agree about this. This perception is at odds with a\u00a02016 review of all research on GM crops\u00a0<\/span>by\u00a0the National Academies of Sciences, Engineering and Medicine<\/a>, which suggests that GM foods are safe to eat.<\/p>\n\n

<\/a><\/figure>\n\n

Public trust in information from scientists in both these areas tends to be higher than it is for information provided by several other groups, particularly industry leaders, the news media and elected officials. But fewer than half of the public trusts information from scientists \u201ca lot.\u201d Some 39% of adults trust climate scientists a lot to give full and accurate information about the causes of climate change. A similar share (35%) of adults trust scientists a lot to give full and accurate information about the health effects of GM foods.<\/p>\n\n

<\/a><\/figure>\n\n

Public views about climate scientists are deeply divided along political lines, with liberal Democrats much more likely than conservative Republicans to see climate scientists and their work in a positive light. For example, 54% of liberal Democrats say climate scientists understand very well the causes of climate change, compared with 11% of conservative Republicans. Republicans who are moderate\/liberal and Democrats who are moderate\/conservative fall in between these two extremes.<\/p>\n\n

By contrast, when it comes to views of scientists connected with GM foods, political partisans are much more in agreement. For example, 20% of liberal Democrats and 18% of conservative Republicans say scientists understand the health effects of GM foods very well. Instead, people\u2019s differences on views of scientists who study GM foods and their research are associated with their level of science knowledge. Those with more science knowledge \u2013 measured by a nine-item index \u2013 tend to see scientists working on GM foods in a more positive light. About half (51%) of those with high science knowledge trust scientists a lot to give full and accurate information about the health effects of GM foods, compared with 18% among those with low science knowledge.<\/p>\n\n

Despite public skepticism about scientists working in both areas, most Americans think scientists should have a major role in policy decisions. About two-thirds (67%) of Americans say climate scientists should have a major role in decision making about climate matters. Six-in-ten Americans (60%) think scientists should have a major role in policy decisions related to GM foods. Scientists are not the only group Americans support at the policymaking table: At least half of U.S. adults think the general public should have a major role in policy decisions on climate change (56%) and GM foods (57%).\n<\/a><\/p>\n\n
