Yes.. metarationality is basicaly a sort of belief system about how and what we can undestand. If we dont undestand our limits and we do not use rationalities as tools we end in scientism or very wrong belief systems built on "fakery" and self delusions..

FYI, it is a synonym for the epistemology (philosophy of knowledge) called constructivism.
