Why do people dwell in ignorance?

I will tell you right now Dr.'s are just as human as you and I. I don't trust them. Knowing all of the mistakes they have made on others we love how can it be that my family still trusts them completely without question?  What kind of crap is that?  I call it laziness!  Do some damn research and find out what is good and what is not.  Don't just trust someone blindly.  That is hiding in ignorance.  It's very frustrating to watch!  Oh well, I wish I knew how to walk through that minefield of my family.  I can walk through any other minefield except my own families.  Why is that?
