->'''[[HeroicDog Bolt]]:''' Calm down, cat. You're with ''me.''\\
'''[[CatsAreSnarkers Mittens]]:''' That's the ''problem!''
-->-- ''Disney/{{Bolt}}''

The opposite of ThreatBackfire, this is for characters saying things that are meant to sound assuring, but those it's being said to perceive as bad.

In other words, Assurance Backfire is to Threat Backfire as ComplimentBackfire is to InsultBackfire.

Can be related to BadOmenAnecdote. (If, for example, one uses as an assuring analogy something that actually ended horribly.) Often related to AnalogyBackfire.

Compare/Contrast with FalseReassurance, wherein the person doing the reassuring is deliberately misleading.

[[folder:Anime and Manga]]
* In ''Manga/MagicKnightRayearth'', when Mokona suddenly whisks the trio high into the air on a flying device, Fuu tries to calm them down by pointing out that if they ''did'' fall, they would be sure to black out long before the moment of impact. Umi, unsurprisingly, is not pleased by this.

[[folder: Fan Works]]
* Twice in ''FanFic/SonOfTheDesert''
** Hohenheim tries to make Trisha feel better about almost killing a suitor but pointing out that it is traditional to kill the proposer. That if she does not love them, she must kill them, because life is not worth living without her. The already-distressed Trisha snaps and tries to make Hohenheim kill her if he refuses her marriage proposal.
** When Ed and Al out themselves as Ishvalans, Fuery tries to assure them that they were only ''half'' Ishvalan. Since Ed and Al are proud of their heritage, this just angers them further.

[[folder:Films -- Animation]]
* ''Disney/{{Bolt}}'' the dog expects Mittens the cat to be calmed down by being reminded she's with Bolt, but she evidently doesn't trust Bolt to know what he's doing because he thinks he really does have superpowers and therefore can perform all sorts of death-defying stunts without realizing RealityEnsues.
* Played for drama in ''WesternAnimation/ThePrinceOfEgypt''. After Moses is finds a mural depicting Hebrew infants being fed to crocodiles--this just after learning he is Hebrew himself--his adopted father, Pharaoh Seti I gives him a hug and comfortingly says... ''they were only slaves.'' His mother's assurance is not quite so horrifying, but her view that "the gods sent you here, so just forget the truth" doesn't help much either.

* In ''Discworld/WitchesAbroad'', Magrat is feeling deeply embarrassed and uncomfortable about having to pose as Emberella at the ball. The other witches try to help.

** And [[FalseReassurance it is!]]
* In ''Literature/HarryPotterAndTheOrderOfThePhoenix'', Harry is worried for his sanity because he suddenly sees skeletal horses pulling the Hogwarts carriages, and nobody else can. When {{Cloudcuckoolander}} Luna Lovegood tells him that she can see them too and he's just as sane as she is, he is less than reassured.
