I respectfully object to this. I’m thinking of research that was done a few years ago, measuring American’s knowledge of current events. The folks in the research that leaned right were generally more informed - meaning, they knew about a lot more currents events. But they were also overwhelmingly wrong about what they ‘knew’. Further, folks on the right tended to rate themselves higher than left-leaning folks wrt their knowledge, even though they were wrong a lot more.
