I'll second this:

The end result of psychological and cultural factors is that most of the common knowledge floating around is highly inaccurate or misleading, often to the point of being simply wrong.

Appreciating this situation is helpful and even empowering. The adaptive reaction to this realization is to be humble before the depth of your own ignorance. To be suspicious of all passive knowledge. To be aware of your own psychological biases. And to be curious enough to seek more accurate and deeper knowledge.

You might summarize all of this by saying – be skeptical.
