"I know for a fact people would rather have people who are flexible and willing to change than someone who says, this will happen and then does it regardless of later facts or information."

Well, even better would be have somebody who *doesn't* say "this will happen" or "this won't happen" until after having looked at the facts. "X will be done" is a bad starting point for a discussion, since some people strangely see that as a statement of fact, and not a starting point for a discussion.
