Wilful ignorance
The Catholics have a related term: "vincible ignorance". They are always talking about what's a sin and what's not, so they need a way to figure out what kinds of ignorance are not culpable.
Yes, you can be ignorant about scientific consensus while advocating your own interpretation, but at some point it becomes willful ignorance and vincible. As countermeasures, you should be able to pass the Ideological Turing Test (ITT). If you advance an unpopular/new theory, pass the Alternative Science Respectability Checklist too.
Wilful ignorance doesn't only keep bad theories alive, it also supports the skewed world-views of those in power, e.g. white people – see Epistemic injustice. Then it's called "white ignorance" or "wilful hermeneutical ignorance".
