[Luis Fok]

Forming an opinion on a subject for which one knows absolutely nothing about and [voicing] that opinion, thus showing lack of knowledge or [ambition] to becoming [remotely] intelligent on the subject mattter.

[Little_Girl]

Most of these definitions are wrong, ignorance is the [assumption] of [utmost] knowing about a subject when you clearly have no clue and when you try to get into a subject you have no idea about, it has nothing to do with being dull or not knowing it is the belief or pretending that you know and trying to give your [two cents] when you have never even researched the topic
