News organizations are coy about admitting that what they present us with each day are minuscule extracts of narratives whose true shape and logic can generally only emerge from a perspective of months or even years -- and that it would hence often be wiser to hear the story in chapters rather than snatched sentences. They are institutionally committed to implying that it is inevitably better to have a shaky and partial grasp of a subject this minute than to wait for a more secure and comprehensive understanding somewhere down the line.
