The only reason this heuristic works is because news companies have become so untrustworthy that when left to their own devices they are only capable of writing negative articles about people. They never take the initiative to report positive news when a person or organization merits it. Even when a person or organization deserves praise, the media finds a way to spin it into a "if it bleeds, it leads" story.
