Why is Critical Thinking Important for Writers?

When I studied Investigative Journalism in college, it was a basic requirement.  For journalists in general, the WHO, WHAT, WHERE, WHEN, WHY and HOW are the tools of the trade.
But everyone, especially writers, should use these question words all the time: when researching background information for a book, when questioning and editing their novels or non-fiction books, when participating in a writer’s critique group and most important: when looking for publishing possibilities.
