"Conservative podcasters were 11 times more likely than liberal podcasters to share claims fact-checked as false or unsubstantiated," the study said.
Fifty-six of the podcasters reviewed shared false or unsubstantiated claims at some point, the study found.
In total, more than 70% of the podcasts reviewed shared false claims at some point, including those described as "liberal," "moderate," or "unknown."
The study noted that it included far more conservative podcasts in its sample as a result of choosing those that are most popular on Apple Podcasts.
The sheer rate of production adds to the issue, it said, with conservative podcasters making longer and more frequent episodes.
