Where there are gaps in your own knowledge, truth becomes about trust and relevance. I don't know that e = mc^2 but I trust scientists that it is the case but it doesn't matter to me much either way; I would not participate in any argument about this subject because although my level of trust is strong, I personally have nothing at stake whether this fact is true or false (it is not relevant to me). People who have a huge ego tend to think that every fact they know is a crucial part of their personal identify; these people tend to avoid saying "I dont' know" because doing so would be an admission that their information sources (which they see as extensions of themselves) are not trustworthy and are therefore low value (which would bring down their own self-worth).
