Has there ever been a time when you were so sure of something only to find out at a later time you were mistaken or misinformed about the truth involving the person or event?  I know I have experience the many, many times.  I have even argued in direct opposition to the truth for years some times to later learn I was actually wrong about the whole thing.  I would like to think you and I are intelligent and view ourselves as a well-intentioned people.  If this has happened to you too, how could this happen to us so many times before?  What can we do to avoid this mistake in the future?
