Harry successfully pulls this off in his first interaction with Lucius Malfoy, quite possibly by accident. When Lucius makes veiled references, Harry responds by playing along... badly. His deception is so obvious that Lucius sees through it almost immediately. Then Lucius starts to think it was too easy - Harry must have been only pretending to be a fool that pretended to understand. He says as much, and walks away, apparently confident that his original message was conveyed. Meanwhile, Harry doesn't have the faintest clue what's going on. Most of the point of Legend of Galactic Heroes is like this, with Yang Wenli and Reinhard (and various other pairs) making plans, which may include knowing their opponent's plans (and sometimes involve a plan being an opponent seeing though the plan, with an extra layer of fake planning below it). Empty City: Zhuge Liang sits alone in an empty city playing his harp while a rival army comes up. They know that Zhuge is a genius and is obviously up to something. Knowing they would know this, the city really is empty, and the whole thing was a stall tactic. That worked. Children of Dune sets up a three or four-way struggle for control of the Imperium, with the demon-possessed Alia on one side, the Bene Gesserit on another, the remnants of the Corrinos as a third, and an unknown quantity in the form of Paul's children, Leto and Ghanima. Leto is captured by people whom he believes to be working for the Bene Gesserit, only to have it turn out that Alia is secretly calling the shots. He himself, however has a deeper plan that eventually trumps all of theirs and renders them moot. According to Pang Tong, the ultimate strategy is to "Let your opponent know your next step. Even more brilliant is to let your opponent know your next two steps." (And then, the next three...)

There is a formal system called modal logic that can be used to model what certain agents in a system know (including what they know/do not know about what the other agents know/do not know). During Draft Day betting at Sports Night Dana and Casey try to figure out if the other knows anything about Tommy Castro's knees, and if so, do they know that the other person actually doesn't know anything about... etc. Ends when Casey explains the entire I Know You Know I Know situation to Dan, while wired so Dana can hear him. I tried to cut my hair once. It was a traumatic blunt bang experience. Who Knows Me Better Questions for Work Friends Suggested on a couple of occasions in Harry Potter and the Alien Reality, such as when Harry stuns a stubborn government official and says the man will wake up naturally in a couple of hours; he could wake the man up earlier with a spell, but so long as nobody asks if that’s possible, Harry won’t lie. The problem is enhanced by the possibility that the defenders may be intercepting and corrupting messages. If it's merely a question of messages getting through, sensible organisation should only require a couple of confirmations before further messages become irrelevant.

Examples:

Washing the dishes. Hands down. They made my fingers all gross and wrinkly. 89. Do I have a green thumb? In Neal Stephenson's Cryptonomicon, Detachment 2702 exists to generate enough random noise to cover up the fact that the Allies have broken German and Japanese ciphers. It stands to reason that if the Axis finds out, they'll switch to a new cipher, so being able to act on the information they got without revealing they have this information becomes very important. Partially Truth in Television; Detachment 2702 is fictitious, but using the information gained from broken codes without revealing that the codes were broken was a major concern for Allied Intelligence. Yes, but if they know I know they know, they may do (X) instead. But what if they know more than I think they know? They could be acting like they only know that I know they know, when in fact they know that I know they know I know they know!"

There is an active research field known as adversarial reasoning: essentially, building models that allow you to predict the actions of an adversary. Once the adversary happens to get a hold of your model it becomes rather useless, as he can make sure he does something other than what is predicted. So you simply create a new model - one that takes into account the fact that your adversary has the old model that he thinks tells him what you think he is going to do! The eventual end state is left as an exercise for the reader. I was a big fan of those rubber shoes with wheels. 83. Do I love fishing, hunting, camping, or spending time in nature? Bob: Okay. I want you to listen very carefully and tell me if I've got this right. You're angry about what you think I said about what you said about what you thought I said (but we now both agree I didn't say) about what you thought I thought you thought about what I did when you did what you did when I didn't do what you thought I said I would do but what I thought I said I would try to do, is that right? This carries over to later parts of the series. For example: In JoJo's Bizarre Adventure: Stardust Crusaders, Jotaro "fakes" his genuine ability to move through stopped time so that Dio would be caught off-guard after calling him on his apparent bluff.EllipsisGoblins : I say stuff to Danielle, then I tweet what I said, then I tell her that I tweeted it and now I'm tweeting that I said I tweeted what I said.

Parodied mercilessly in the National Lampoon's Doon, where two characters have a half-hour long conversation without knowing what the other is talking about. This quiz calculates how much you and your friend or couple know each other after answering a set of questions. To play, first answer questions about yourself. Then pass the device to the friend you are playing with and let them answer the same questions, trying to get their answers to match yours. At the end of the game you will get a total score of how well they know you! This exact scenario, with whatever permutations, has gone on in in the mind of every person who has played the game in real life, at least once. The first series in The Chronicles of Amber is about a large, immortal, royal family with the powers of demigods squabbling and scheming over the throne after the disappearance of their father. Being that they've had centuries worth of spying on one another, studying each other in an attempt to find and exploit any possible weaknesses, making and breaking alliances as soon as it's advantageous and so on, there's a lot of this going on.Zhuge Liang's Empty City Ruse (from the fictionalized parts of Romance of the Three Kingdoms) relies on this. The Flintstones has one of these. It's something to the effect of "Even though he knows she knows he knows he knows she knows he *doesn't* know..."

Ross: Wait a minute. Wait a minute, you-you hated the name Ruth. Why...Why would you change your mind? Unless...you know we're never going to have to use it. You did see the folder. You know it's a boy! Played for laughs in Losing It All when an Alternate Universe Xander is asked by Cordelia if he's evil (he's arguing he might be and she's arguing he's not). After a few layers of "I know you know", Cordelia stops it by pointing out he isn't smart enough to think that far ahead, causing Xander to admit he isn't evil.Richie in The Class (2006) must determine how Duncan's date went for Nicole, but since he's a Bad Liar, he ends up revealing Nicole's secret, then Duncan's secret, then both. Very common in counter-espionage, classic example is Radio Game . Allies sent a spy, Germans knew that he was a spy and turned him, Allies knew that the Germans knew, Germans knew that the Allies knew that they knew and finally ended the charade. A semi-real life example, meaning it's actually an urban myth, is Winston Churchill's Coventry dilemma. Allegedly, Churchill had to allow the city of Coventry to be bombed, to prevent the Nazis from finding out about the British spies in Germany who knew about the bombing plan. In reality, the British tried to jam the Germans' radio guidance system , but had to take a guess at the frequency to use. They got it wrong. Kim Possible: Kim and Ron notice that Shego left a far too obvious clue that she had stolen the MacGuffin, so clearly she and Drakken were setting up a trap. Unless they wanted them to think it was a trap and avoid it, in which case the way to confound them was to walk right into it, except it was a "trap-trap": Drakken knew that they knew that Drakken knew that they knew that it was a trap.
