"I believe that you believe it" is a Stock Phrase that can occur in several different contexts. For example:
Either way, Bob's not accusing Alice of lying, but he's still not quite as understanding as Alice might hope. He's implying (in the former case) that she's over-imaginative, paranoid, even crazy, or (in the latter) that she doesn't know herself as well as he does or that she lacks follow-through. In any case, Alice usually finds it pretty insulting, even though in most cases Bob means well by it. Related to Damned by Faint Praise, Trivially Obvious. Not related to believing in someone who believes in you.

- When the Chainfire spell was unleashed, Richard had this exchange with half of the most dangerous people in the world. In their defense, they'd had their minds magically tampered with, and Richard only escaped it because he held the carefully-named Sword of Truth. Of course, since he was the single disagreeing data point, they all assumed that he was the problem and nearly tampered with his brain for his troubles.
- Crops up in the Honor Harrington series frequently where Mesa is involved, often becoming a motivation to track down hard evidence. An example would come in At All Costs, when Honor is visited by Anton Zilwicki and Victor Cachat. They inform Honor that Haven was not responsible for a series of assassinations and have compelling arguments, but no hard evidence. Between this and the empathic abilities shared by Honor and her treecat Nimitz, Honor does not think they're lying, but the lack of evidence means that they're only telling the truth as far as they know it, leaving open the possibility of black ops plans they wouldn't been aware of. This is what prompts the pair of spies to head for Mesa for more concrete evidence, leading to the discovery of the Mesan Alignment.

- In Peanuts, Linus got this reaction from Peppermint Patty after he told her about the Great Pumpkin.
- In Dungeons & Dragons, a successful use of the Bluff skill is used to make someone believe you're being genuine even when you're not. As The Order of the Stick can demonstrate, it is much too easy to buff this skill to the point where even the most Blatant Lies will stick without any trouble. Many GMs therefore declare that "convincing the NPC you're being genuine" doesn't mean "convincing the NPC to believe what you said", and the NPC will just decide you're a very strange person who honestly believes something clearly false. Pathfinder made this fix explicit.
- This is basically the entire reaction of the Tau in Warhammer 40,000 where the Warp is concerned. Since they have a natural immunity to anything Warp-related, (including, but not limited to, Hearing Voices, psychic powers, and that perennial favorite Demonic Possession), they see the Imperium happily slaughtering their own men by the thousand to prevent this kind of corruption, but simply can't imagine it happening to them (they know Chaos daemons exist, but see them as a race of psychic aliens rather than sentient emotion given form, and their FTL travel doesn't go near the Warp, but is much slower, so no Hyperspace Is a Scary Place for them).
- In Dragon Age: Origins, the PC can say this about Leliana's vision.

- Kyle uses this line on Cartman in the South Park episode "Fishsticks", where Cartman is concerned that Jimmy is going to take all the credit for a joke they "co-wrote." Kyle tells Cartman that he believes Cartman thinks he helped write the joke because his ego won't let him think otherwise.

- Medieval heretics didn't like to be caught by the Inquisitions but a lot of them also didn't like to lie, since that was frequently one of those things that they found so reprehensible about mainstream religion that they would bother to be heretics with the associated risks and effort, so Inquisitors' manuals are full of warnings of their trying tricks based on this. Especially in the form:
Inquisitor: Do you believe in the one true faith?Heretic: I am unlearned, this I do not know. What is this faith?Inquisitor: We believe that [insert orthodoxy].Heretic: This I believe.
- With notes emphasizing that what the heretic means in this case is "I believe that you believe this, though I do not."
- Jay Leno's interview on the Oprah Winfrey show. Oprah was talking about her decision to stop doing her show.
Jay: I'm not going anywhere; neither are you. [snip]Oprah: You don't believe I'll do it?Jay: I believe that you believe it.
- This is effectively how the United States and the People's Republic of China deal with the issue of Taiwan when the two established formal diplomatic relations in 1979. Up to that point, the United States recognized the Republic of China on Taiwan as the sole legitimate ruling authority of China, and both the PRC and ROC maintain a "One China" policy (the difference, of course, being who represents that One China)note . To get around the potential relations nightmare (both international and public) of dropping the anticommunist government for the communist one in the midst of the Cold War, the US's official position on the issue (as expressed in the Shanghai Communiqué of 1972) is that it "acknowledges" the PRC's position on the One China policy (as opposed to "endorsing" it). China was willing to go along with this in order to develop relations with the West after the Sino-Soviet Split.
