Pattern family
The trick sits in the shape of the claim or the choice of words, not in any fact a reader could go check. A position built to survive every counterexample, a word that quietly changes meaning partway through an argument, or a frame that decides what the subject is before anyone notices a subject was chosen.
The unfalsifiable claim
Public discourseEvery possible outcome was already counted as proof. You just hadn't noticed there was nothing left that could count as disproof.
No true Scotsman
Public discourseEvery counterexample gets a new definition built around excluding it. The category never loses. It just keeps shrinking.
Motte and bailey
Public discourseWhen pressed, retreat to the defensible fortress. When unpressed, raid from the extreme castle.
Retroactive theologization
Public discourseThe explanation existed before the event did. You noticed that. You were not supposed to notice that.
Post hoc
Public discourseIt happened after. That is the entire case for why it happened because.
Slippery slope
Public discourseStep one was reasonable. Step ten was the point. Nobody showed their work on how you get from one to the other.
Moving the goalposts
Relationships and groupsYou met the standard. The standard was moved. That was the plan.
Affect conditioning
Public discourseYou felt it before you understood it. The feeling was placed there ahead of the facts, so your gut would vote before your mind could.
Context narrowing
Public discourseYou looked where the light pointed. You did not notice the rest of the room going dark.
Harm sanitization
Public discourseThe thing was ugly, so they renamed it. The new name let you look without flinching.
Word salad
Relationships and groupsYou left the conversation more confused than when you entered it. The confusion was the deliverable.
Strategic ambiguity
Public discourseYou accepted the vagueness because precision would have forced you to pick a side. You did not want to pick a side. They knew that.
Domestication
Public discourseYou preferred the version that asked nothing of you. The preference felt like wisdom. It was the removal.
Equivocation
Public discourseThe word meant one thing in the premise and another thing in the conclusion. Nobody announced the swap. The sentence just kept going.
Dog whistle
Public discourseOne sentence, two audiences. The deniability is aimed at the larger one.
Hasty generalization
Relationships and groupsYou met three people who fit the rule, and built the rule out of the three. Nobody ever went back to check whether three was going to be enough.
Burden of proof
Public discourseYou asked for evidence. What came back was a demand that you prove the claim false yourself.
Fallacy of composition
Public discourseWhat's true of every brick is not automatically true of the wall.
Fallacy of division
Relationships and groupsThe wall is sound. That doesn't make every brick in it load-bearing.
