While much research has revealed the prevalence of climate change misinformation on social media, there is no conclusive evidence about its impact on cultivating public misperceptions. Even less work has been done to examine how social media use may condition the relationships between cognitive orientations, such as epistemic and science populism beliefs, and climate change misperceptions. This study fills this gap by analyzing data from a national representative survey of 1405 US adults. Results confirmed the relationships between cognitive orientations and climate change misperceptions. While neither mainstream nor alternative social media use had a direct impact, both types of social media use conditioned the relationships between cognitive orientations and climate change misperceptions. This study’s findings suggest that social media use’s adverse impact on climate change misperceptions may have been overstated.
