    The normal kind -- it's rare to find someone aware of their ignorance -- such a person would be a sage. – Kris Jul 30 '15 at 13:11

There is a phrase blissful ignorance that has been in use for centuries. Examples can be found following this ngram.

Oxford Dictionaries Online defines it as

Fortunate unawareness of something unpleasant.

As the definition indicates, its application is much broader than erroneous pontification, and the unpleasantness will be felt by the listeners, not the speaker.

Bloviate means

Talk at length, especially in an inflated or empty way.

Oxford Dictionaries Online

Again, this is broader, and may include talk that is hollow, but not necessarily erroneous.

Or you might coin your own phrase, such as master of misinformation.

I personally like the term ignoramus.

a person who does not know much : an ignorant or stupid person

Also called

unknowledgeable, uneducated, or uninformed; a fool.
