Understand that if you felt something that connected you with where your devices come from — that is not a lie. That is art.
If you use real people and real events, you don’t get to lie. No dramatic license, no aiming for a larger truth, no composite characters, no changing things around for better narrative flow, no “art.” No lying.
I get it. Actual events can happen slowly, or not at all, intermittently, inconclusively, inconveniently, and not in useful way for story-telling. I also understand that, for example, history and historians never get to the pure unvarnished objective truth of myth and legend. There are too many distortions, too many intervening years, too many people, sources, and all the grand filtration that the past goes through before reaching its reporter. I know too that historians often produce pedantic, waffle-full, carefully-couched, well meaning but utterly boring recitations. Their books fly off the shelves only when someone yanks too hard on the David McCullough biographies beside them.
All that is true, and irrelevant. Using real people with real lives and real names as your subjects gives a singular advantage over fiction: the conviction and credibility of reality. The power of talking about things as they are, rather than as you imagine, goes bone-deep with the audience. It goes too deep for disclaimers and denials and claims about artistic license to overcome. That is its great value.
The payment for that power is a duty and responsibility to your subjects, to your audience (now and future), to your peers, and to the act of explanation and narration itself, to speak the truth as you understand it, in all details big and small. There is no “larger truth” that you get to by lying. If you wish to speak the truth, you must actually speak the truth.
