The more you know the more susceptible you are to going bat crazy. Hence the phrase "ignorance is bliss." While a yearning curiosity to understand the world around you is admirable (and an act which can help usher forward progress for all of humanity), maintaining sanity and objectivity simultaneously is a complex skill one must also learn to acquire. It shouldn't be taken lightly. Otherwise, for your safety and for the safety of others, you might as well remain ignorant.
