Show, Don't Tell
"A little less conversation, a little more action..."Badass:
- To show that Alice is a badass, she would spend the entire book doing indisputably badass things. More pertinently, the book would go into detail: for instance, the work could begin with a Batman Cold Open where she takes on six mooks without breaking a sweat. In these circumstances, we don't have to be told she's badass; we can see it for ourselves.
- To tell that she is a badass, the narrator, Alice herself and/or other characters around her would merely state that fact. For instance, they might report on previous incidents that have happened in the past and/or "offscreen" while the other characters were busy. Or maybe there'll be no support for the statement whatsoever, but that's unlikely ("Hey, did you hear about the badass things Alice did the other day?" "No, I didn't." "Well, they sure were badass!" *crickets*). In particularly egregious works, the narrator may state that Alice is a badass, even going so far as to include list of badass things she did, and then never mention it again or—taking the cake here—not have her act badass when the option is available.
- As You Know: As you know, this is when a troper like you recognizes the act of characters giving out exposition nobody in the scene would need.
- Info Dump: Infodumping (that is, information + dumping) is a type of Exposition that is particularly sesquipedalian. Although it can be done in a way that is unintrusive or entertaining, most infodumps are obvious, intrusive, patronizing, and sometimes downright boring. Specifically, if the premise of your story is laughably ridiculous, an infodump will call attention to the fact. This infodump, for instance. The word 'infodump' is often used as a pejorative.
- That Makes Me Feel Angry: It makes me sad when writers resort to just having their characters say what they feel in so many words.
- Explaining Your Power to the Enemy: When a character's power is spelled out by that character, rather than made clear through visual representation.
- And That's Terrible: When the narrator reminds the audience, in case they missed it, that what the villain did was terrible. Which is a bad device and shouldn't be used.
- Meaningful Name: A quick (some might even say lazy) way to let us know what a character is like.
- Narrating the Obvious: When a story shows and tells.
- Said Bookism: "In which the nature and intention of dialogue is told by the dialogue tags as well as by the dialogue itself," the TV Trope page vocalized speechlessly with passion and vigor.
Telling that contradicts shown behavior or evidence:
- Character Shilling: "Wow," said Alice, "Bob is the most amazing guy in this whole story, isn't he?" "He sounds wonderful; I can't wait to meet him," said Carol.
- Continue Your Mission, Dammit!: There isn't much time left because people keep telling you there isn't much time left. You have 35 seconds to finish this page.
- Designated Hero: When we've got nothing but the narrative's word for it that the fellow the book follows is, in fact, the good guy.
- Designated Love Interest: When we've got nothing but the narrative's word for it that the fellow the book follows is, in fact, romantically attached to the heroine.
- Designated Villain: Likewise, the character in question has never done anything especially evil, but the narrative leaves no room for doubt. Often paired with Designated Hero, though you can have one without the other.
- Faux Action Girl: We're told she's a badass, but it certainly doesn't look that way.
- Hollywood Homely: Casting an attractive actor or actress to play someone who's supposed to be bland looking or even downright ugly.
- Hollywood Pudgy: Alice is of ideal or slightly below ideal weight, has broad shoulders, and has round cheeks. Alice is fat.
- Informed Attribute: We are told that Alice is smart/funny/ugly/pretty/can turn into a bat, but we never see any evidence for this.
- Informed Ability: "...and Alice, who could turn into a pink butterfly on a whim, dragged herself out of bed and drove to work."
- Informed Attractiveness: Alice is described as drop-dead gorgeous in story, but the audience doesn't really react to her that way.
- Informed Deformity: "Alice and Bob might both have been stick figures, but by God, he was hideous."
- Informed Flaw: You are blind.
- Informed Judaism: "Oy vey", said Alice, munching on a bagel. "Didn't you guys ever notice I don't go to church on Sundays?" Bob replied, "I noticed you don't go anywhere on Saturdays, either!"
- Informed Loner: "I don't like being around others," said Alice to Bob and 20 of their very best friends. On being told this, nobody left the room.
- Informed Poverty: Alice is said to be poor yet she lives in one big house.
- Informed Wrongness: Bob told Alice that the moon orbits the Earth, ignoring the clear evidence she'd presented that everything in the universe orbited her. Well, we can't all be smart like Alice.
- Offscreen Moment of Awesome: While you were away, the hero defeated the villain in a truly epic battle; you'll just have to take our word for it because it was awesome.
- Offstage Villainy: The villain is said to have done something malicious, but we do not get to see it happen to understand how evil he/she really is.
- The Pirates Who Don't Do Anything: Have a job which would involve distinctly non-heroic behavior for your hero? Don't worry, just don't have them do it. It's not like killing people is an important part of being an assassin anyway.
Showing instead of playing:
- Cutscene Power to the Max: Your character is significantly more able when you're not playing as them.
- Cutscene Incompetence: Your character is significantly less able when you're not playing as them.
- Gameplay and Story Segregation: The game mechanics don't work the same way the storyline does, or the story doesn't match the way the player is allowed to behave. This often comes across as the game simply ignoring whatever the player is doing to tell a fixed, immutable storyline.
Playing instead of showing:
- Instructive Level Design: Objects in the levels are assembled such that the designers don't need to say anything to you.
- Malevolent Architecture: Environments may be twisted or something in such a way as to make you anxious when moving through them.
- Bolivian Army Ending: When it's already obvious that the protagonists have met their match.
- Discretion Shot: Writers imply that something violent or sexual happened without showing it to avoid censorship.
- Informed Conversation: The "would otherwise be repeating what the audience has seen already" and "distill the plot" variants.
- Great Offscreen War: Not every writer can convincingly depict a war. Especially if they have no experience with the subject.
- Noodle Incident: Writers don't even tell the details, to let imaginations fill in the gaps.
- Noodle Implements: Stating items used, but not how, to let imaginations fill in the gaps.
- Nothing Is Scarier: When the writers use our imagination to make us fear.
- Take Our Word for It: Writers describe something they can't possibly live up to by showing it, so they just tell us what it's like, and let our imaginations fill in the gaps.
- Time Skip: No one wants to read or watch through a lengthy sequence of events where nothing particularly interesting, exciting or relevant to the plot happens. Under such circumstances, it's quite acceptable to just jump from one relevant bit to another relevant bit and tell your reader / viewer that it's "ten years later" or "it took him fifteen minutes to get to the shop" and leave it at that without showing what happened during that time in unnecessary detail.
- You Cannot Grasp the True Form: Otherworldly entities and places are impossible by definition to actually pull off.
- You Do Not Want To Know: Some secrets are best left unrevealed.
Showing that slows the narrative:
- Costume Porn: Writers attempting to show how detailed clothing is, even though it usually is not necessary to do so.
- Description Porn: Description that goes into so much detail that the reader will soon shout "Get on with the story already!"
- Purple Prose: Pretentious, extravagant wordplay that will make readers want to skim through for fear of pages and pages of mundane description.
