Chart of the day: Republican science-blindness


From the Pew Research Center, which reports:

People’s level of science knowledge helps to a degree to explain their beliefs about climate change, but the relationship is complicated. While there are wide political divides in public views of the potential for harm from climate change. A majority of Democrats holding medium or high levels of science knowledge said it was “very likely” that climate change would lead to rising sea levels that erode beaches and shore lines, harm to animal wildlife and their habitats, damage to forests and plant life, storms that are more severe, and more droughts or water shortages. But there are no differences or only modest differences among Republicans holding high, medium and low science knowledge levels in their expectations of harms to the Earth’s ecosystems because of climate change.

Similarly, Democrats with high levels of knowledge about science, based on a nine-item index, almost all agree that climate change is mostly due to human activity (93%). By contrast, 49% of Democrats with low science knowledge think this is the case.

But among Republicans, there are no significant differences by science knowledge about the causes of climate change. Put another way, Republicans with high levels of science knowledge are no more likely than those with lower levels of knowledge to think climate change is mostly due to human activity.

This pattern did not occur on all judgments related to climate change, but to the extent that science knowledge influenced judgments, it did so among Democrats but not Republicans. (See our report “The Politics of Climate” for the results from statistical models of these patterns.)
