Please help me paraphrase these two words! Thank you!

Sentence One : （the last sentence in the following paragraph）
It’s safe to assume if you knew something was wrong, you wouldn’t believe it
was real and true in the first place. But in a world where so much of industry
applied craft has morphed into long-held mythologies, much of what everyone believes is false. This isn’t any different from long ago when humanity believed the world was flat. You needn’t beat yourself up if you fall prey to false mythologies. Pretty much everyone has and does. Once you know and accept that, you can begin gaming everyone else.

Sentence Two: （the last sentence in the following paragraph）
If sorting false mythology from fact were trivial, there wouldn’t be so many false truths. While this isn’t trivial, it isn’t impossible either. One inherent difficulty is this approach requires being skeptical about all you r prior beliefs, something most humans dislike. In fact, most humans hate selfquestioning and prefer spending time convincing themselves and others
their beliefs are right. Effectively you can’t trust any conclusion you thought
you knew.
