Is a little knowledge dangerous ?

A lot of doctors try to put patients "in their place" by showing them how little they know. Also, many family members discourage patients from getting information about their problem, by suggesting that: medicine is too complex; it will all go "over their heads"; and that "the doctors knows best". While it is true that a little knowledge can be dangerous, ignorance ius far more harmful ! A good doctor will help you build on your knowledge-base, rather than try to insult your intelligence or pooh-pooh your efforts to become better informed.
