"When programmers invented rubber duck debugging they were right but what they don't tell you is that this also works for like 90% of other complex intellectual tasks. Nothing solves a problem faster than just trying to explain it to somebody."

Alice has a problem and she goes to Bob for some advice. She pours her problems out to him, unaware that he isn't paying attention, but by the end of their "conversation" she's figured out the answer to her problem and thanks Bob for his help. On the other hand, Bob may be all set to give her some advice, but before he can get a word in, Alice comes up with a solution and runs off, thanking him, and leaving Bob bewildered, though he'll still probably say, "You're welcome." If Bob contributed anything at all, it was simply to serve as a catalyst for Alice to re-state (and thereby re-think) her problem. Bob may even be unconscious the whole time.

In short, this is when a character has a "Eureka!" Moment without being inspired by the other character, but acts like the other character gave them just what they needed or thought they needed. Sometimes the other character isn't actually listening in the first place - they're asleep, or they've left the room, etc. Sometimes it's an animal, a person who they share no languages with, or The Silent Bob. When invoked, an outright inanimate object, such as a stuffed animal or the famous rubber duck, is another common alternative.


A common variation is for a character to be visiting their therapist, who doesn't say much more than "hmm," and "I see," yet they leave the session feeling much better (in fact, psychoanalysis actually recommends that the therapist say as little as necessary, partly to prevent them from putting words in the patient's mouth and partly to encourage the patient to talk themselves).

Also known as Rubber Ducking IRL. At the other extreme we have Glad I Thought of It. Compare Explain, Explain... Oh, Crap! for another situation where the act of describing the situation leads a character to a (much less helpful) understanding. See also Repeat What You Just Said.

  • In The Lion King 1 ½;, Rafiki comes to advise Timon some time after his friends have left him to go fight evil. Since Timon has been lonely for days at this point, he doesn't even bother hearing what Rafiki has to say and instead mimics what he thinks the baboon is about to say. Which, based on what Rafiki says after Timon charges off towards the Final Battle, is actually pretty accurate.
    Rafiki: My work here is done.

  • The third act of Charlie and the Chocolate Factory has Willy Wonka laying on a Freudian Couch with an Oompa-Loompa in the psychiatrist role. As Wonka details the problems he's currently facing with his candy-making, he suddenly realizes where he's gone wrong. He sits up and thanks the Oompa-Loompa, who hasn't said a word the whole time.
  • In a cut scene from Galaxy Quest, the engineers approach Fred (Tech Sergeant Chen) with a problem. In the process of explaining it to him, they stumble upon the solution, then give him the credit.

  • Some of Hermione's I-think-I-just-had-an-epiphany-I'm-off-to-the-library moments in Harry Potter were like this. Lampshaded by Ron at least once (he hates it when she figures something out and then leaves without telling them what it was).
  • Rin, in Shannon Hale's Forest Born has the gift for helping people this way, due to her quiet and accepting nature.
  • Momo, by Michael Ende. Momo is a little girl who basically solves everyone's problems by simply listening to them. She never gives any advice at all, but the people who talk to her suddenly come up with ideas and solutions.
  • One of the many reasons Sherlock Holmes keeps Watson around; explaining his cases to someone with less understanding often gives him just the brainstorm he needs.
  • Psmith's relationship with Mike as his "confidential secretary and adviser" seems to embody this. Psmith is constantly praising Mike for his "invaluable" intelligence, despite the fact that he rarely lets him even get a word in edgewise; the truth is he likes having an audience.
  • Dirk Gently's Holistic Detective Agency addresses the first example listed under Real Life below; computers are logical, but lack common sense. As such they make an excellent substitution for a particularly dimwitted student; by breaking down a process into simple logical steps that a computer can understand, you are bound to understand the process better yourself. Very much Truth in Television.
  • Mused about in Jingo by Lord Vetinari, who thinks that when people go ask other people for advice it isn't because they want their help. They just want someone to be there while they talk to themselves. He does it himself with Leonard de Quirm, a man detached from the city's interests and thus someone he can talk at.
  • In The Hitchhiker's Guide to the Galaxy, Slartibartfast has just told Arthur that Earth is a constructed planet commissioned by mice, who have been experimenting on humans. Arthur corrects him, saying it's humans that experimented on the mice. He goes into a long spiel about it, ending with "From our observations of their behavior we were able to learn all sorts of things about our own...". The narration simply says that his voice trails off, implying the sudden realization. Slartibartfast simply complements the mice's subtlety.

  • Happens in the Castle episode "Punked". Alexis asks her dad how to know if she's in love, but before he can give her any advice, she rambles on about it, coming to her own conclusion, but thanking him as if he gave her the answer. Quoth Castle as she runs off, "Glad we had this talk."
  • Frasier, when Frasier asks for his brother's advice, he basically uses him as a Straw Therapist while he diagnoses himself.

  • Monk, as well, at least once each with Dr. Kroger and Dr. Bell, as well as a time or two where he used a non-therapist as a wall off of which to bounce ideas.
  • The therapist Maddie talks to (or rather at) in the Jonathan Creek episode "The Scented Room".
  • The second episode of Scrubs did this, where first J.D. and then Elliot did this with Dr Cox. This cemented Dr. Cox as the guy people (especially J.D.) came to with problems, much to his annoyance (especially when it involved J.D.).
  • Doctor Who: With the Doctor around, this is almost a given. He'll be talking to his companion and then he'll explain what he had figured out. His companions will still wonder what he said!
  • House, usually at least Once an Episode. Sometimes House and Wilson will be in the same room and talking, but having two entirely different conversations, and something Wilson says or does causes House to get up and leave, generally without explanation. One time when both his team and Wilson were unavailable, House commandeered a passing janitor to be his sounding board; apparently he's physically incapable of being brilliant without someone there to witness it.

  • The therapist in Phantasmagoria 2 had surprisingly little to say about Curtis's various revelations: everything from being dressed as a girl by his horrifically abusive mother, to his attraction to both his female co-worker and male best friend, to his interest in bondage. You'd think there would've at least been a comment of note. Oh well, Curtis seemed pleased with the sessions.
  • An Absent-Minded Professor mage in The Elder Scrolls V: Skyrim can be asked about her research, and she'll tell the player about problems she's having. If instead of admitting to having no idea what she's talking about you respond with random gibberish ("Uh... Seven?") she'll filter it through several layers of Bat Deduction and come to a breakthrough, thanking you for your insightful advice.

When she laments that the Aledo, an automated starship, didn’t do the same scans she did, Captain Freeman overhears it and realizes the ships are flawed and runs off to point that out.
Tendi: That was weird… but I’ll take it!

    Real Life 
  • There is an old academic advice that basically says, if you want to understand what you're learning, find someone who knows even less than you to explain it to. In other words, in the process of breaking down an idea for someone else to understand you also get a better understanding of it (this is very much a truth; even if you thought you got it before, it can reveal a lot of mistakes or parts that you have skipped.)
  • In software development, this is called "rubber duck debugging." It's a technique where you try to fix a problem by describing it to an inanimate object, like a rubber duck or a stuffed animal. The supposed reason this works is because saying your thoughts and actions out loud forces your brain to actually think about what you're doing instead of going on autopilot, so you catch any mistakes or oversights you missed.
  • The same principle is why reading back your written work aloud better helps you to catch typos and errors. So long as the first and last few letters of a word are in the proper order, our brains usually just spackle over mistakes whenever we read our own written materials quietly (as denomstarted by expremients shownig that this parnetehical is prefetcly undrestnadable to msot poeple at frist galnce, depsite most wrods in it bieng misplled).
  • The ELIZA program, a "psychoanalytic" computer program where people would type in their problems (for instance, "People don't like me") and it would just throw their statements back at them in the form of questions ("Why do you think people don't like you?"). The majority of users said the program helped them feel better, despite the fact that ELIZA didn't give any actual advice.
  • Ancient oracles might also used what modern people might consider psychoanalysis instead of being just mere fortune-tellers. They listened to the supplicant, let them tell their whole story, and at the end, they only said a very short, cryptic answer. This could allow the supplicant to think through his problem and find a solution.


Video Example(s):

Alternative Title(s): Rubber Ducking


Skipped the Prime Directive

When Tendi is beating herself up over the Cerritos losing the race to the Aledo because she pointed out the potential signs of sentient microbial lifeforms, her friends assure her that she did the right thing. She asks, if it was really the "right thing", then why didn't the Aledo slow down too? Freeman overhears this, and realizing what it means, excitedly tells Tendi 'You're right!' before running out of the room.

How well does it match the trope?
