Information overload........................part two

     In theory, the ongoing explosion in information should make the right answers more obvious.  In practice, though, being surrounded by data often makes it harder to decide.
     This inability to take advantage of data as it becomes more plentiful is called "information blindness."  Just as snow blindness refers to people losing the capacity to distinguish trees from hills under a blanket of powder, so information blindness refers to our mind's tendency to stop absorbing data when there's too much to take in.
