Show, don't tell
Show, don't tell is the craft maxim that you should dramatize a moment rather than summarize it. Here is what it really means, when to ignore it, and why AI leans toward telling.
Show, don't tell is the most repeated piece of writing advice, and the most misunderstood. It means dramatizing a moment so the reader experiences it, rather than summarizing it so they are merely informed of it. Not "she was furious," but the way she sets the cup down too gently. The reader draws the conclusion, and a conclusion you reach yourself lands harder than one you are handed.
The honest version of the rule has an exception built in. Telling is not a sin; it is compression. You tell when you need to cross three weeks in a sentence, when a detail does not earn a whole scene, when the pace needs to move. Strong prose shifts between showing and telling deliberately. The maxim exists because writers over-tell, not because telling is wrong.
Why AI tends to tell
A language model reaches for the summary because the summary is the most probable, lowest-risk sentence. Asked for an emotion, it labels it: "he felt a wave of grief." That is telling, and at scale it is one of the textures of AI slop. Generated prose drifts toward stating feelings because stating them is safe, and safe is exactly what the average produces.
Turning telling into showing in an AI draft
This is one of the highest-value edits to make on a generated draft. When you hit a labeled emotion, ask what the reader would actually see: the gesture, the held breath, the thing the character does instead of saying how they feel. Replacing the label with the behavior is most of the distance between flat generated prose and prose with a pulse. It is close work, the kind a line editor does.
