Here is a quote from that research paper:
researchers have identified numerous conspiracy theories that garner more support among the right than left, including those calling into question the scientific consensus on climate change (Miller et al., 2016), the authenticity of Barack Obama’s birth certificate (Pasek et al., 2014), COVID-19 (Miller, 2020), and the election of Joe Biden (Pennycook & Rand, 2021). Second, some researchers show that conservatives display higher levels of generalized conspiracy thinking than liberals (van der Linden et al., 2021); similarly, others show that “extreme” conservatives are more likely to believe conspiracy theories than “extreme” liberals (Imhoff et al., 2022; van Prooijen et al., 2015). Third, conspiracy theory beliefs are sometimes found to be associated with psychological tendencies more prevalent among conservatives, such as authoritarianism, need for cognitive closure, and threat perception (e.g., Dyrendal et al., 2021). Finally, several studies find evidence that those on the right are more likely than the left to engage with fake news and misinformation online (Garrett & Bond, 2021; Grinberg et al., 2019; Guess et al., 2019).
But the abstract then claims the exact opposite!
