Scientists are in near-universal agreement that human activity is a primary cause of climate change. Yet, despite this scientific consensus, the American public remains divided when it comes to beliefs about human-induced climate change. We investigate the role of partisan group identity and the politicization of science in undermining the impact of a scientific consensus message about human-induced climate change. We do so with a survey experiment administered on a nationally representative sample, finding that partisan identity – and especially politicization – can stunt the effect of a scientific consensus statement about climate change. We conclude with a discussion about how scientists, as a group, might work with partisans to more effectively communicate scientific information.
