Module 13 — The Tricks and Cheats of OCD
A doubt that starts losing does not surrender. It litigates. The moment a person begins applying the skills of this course, taking one clean look, filing it as containing nothing, walking away, the doubt switches tactics and starts arguing back, and here is the remarkable thing: the counterattack draws on the same small set of moves regardless of the person or the theme, delivered in nearly identical words every time.
Clinicians hear these lines so often they can finish them. I-CBT calls them the tricks and cheats of OCD, and the fact that there are only a handful of them is one of the best pieces of news in this course, because a rhetorical repertoire this small can be memorized, and a trick that has been named to its face stops working. These are different animals from the story devices of Module 6: the devices are the doubt's founding narrative, written before the argument starts; the tricks are its live debate moves, deployed in the moment, when the doubt is cornered and needs sixty more seconds of your attention. This lesson catalogs the repertoire and teaches the one skill that beats all of it.
The Tricks
Here is the catalog. Every trick is presented with its exact line, since recognition depends on knowing the wording, followed by an exposure of what that line smuggles, because each one works by slipping something past the listener in plain sight.
But It's Still Possible.
The line: "Fine, there's no evidence, but you can't say it's impossible, can you?" This is the doubt's oldest and most-used move, deployed the instant an evidence audit goes against it. What it smuggles: the equation of possibility with relevance. Almost nothing is technically impossible, which is true and completely beside the point, because life runs on what is relevant rather than on what is conceivable. The ceiling could fall during dinner; nobody eats in a helmet. The trick asks a person to grant one imagined scenario a status they extend to none of the millions of others they cheerfully ignore all day.
Better Safe Than Sorry.
The line: "It only takes thirty seconds to check. Weigh thirty seconds against your whole house." What it smuggles: a rigged cost-benefit sheet. The "safe" being purchased is protection from an imaginary problem, so its actual value is zero, while the price is real and compounding: thirty seconds grows into six checks, then an evening, then a life arranged around checking. Relief from a threat that never existed is bought with the real day, and the trick never once shows the running total.
The Feeling Proves Something.
The line: "If there were really nothing to this, would you feel this anxious? The fear must mean something." What it smuggles: a reversal of cause and effect. The anxiety is a response to the doubt, manufactured downstream of it, exactly as Module 3's sequence laid out, and the trick launders that downstream product into upstream evidence, as though the alarm a false report triggered were proof the report was true. The feeling is real; what it proves is only that a doubt fired, which was never in dispute.
A Good Person Would Check.
The line: "One more check, a real one this time, and you'll finally be sure. Then it's over, promise." What it smuggles: a carrot on a stick, the certainty that recedes at exactly the speed it is approached. Every person reading this has taken the deal, some hundreds of times, and can consult their own data: the promised "finally sure" has arrived exactly never, because, as the bubble lesson established, the check is delivered to an address the doubt doesn't live at. The trick's genius is the words "one more," which frame an infinite series as nearly finished, when in reality it has been one more for years and always will be.
Just One More Look.
The line: "One more check, a real one this time, and you'll finally be sure. Then it's over, promise." What it smuggles: a carrot on a stick, the certainty that recedes at exactly the speed it is approached. Every person reading this has taken the deal, some hundreds of times, and can consult their own data: the promised "finally sure" has arrived exactly never, because, as the bubble lesson established, the check is delivered to an address the doubt doesn't live at. The trick's genius is the words "one more," which frame an infinite series as nearly finished. It is always one more. It has been one more for years.
What If This Time Is Different.
The line: "Sure, it's been fine a thousand times. But what if tonight is the night?" What it smuggles: novelty as a credential. The trick concedes the entire record, a thousand uneventful nights, then asks for an exemption on the grounds that this particular evening is unprecedented, while offering nothing to support the claim except the assertion itself. Every night is new in the trivial sense of having a fresh date, and the trick dresses that triviality up as information. A person who looks for what actually sets tonight apart discovers the same thing the evidence audit always finds: nothing from the situation..
You Can't Be 100% Sure.
The line: "Admit it. You can't be absolutely, completely certain. So the question is still open." What it smuggles: a standard of proof applied nowhere else in the person's entire life. Nobody is 100% sure the brakes will work, yet everyone drives; the same person orders dinner without certainty that the kitchen is clean, boards planes, confides in friends, and walks across floors, operating beautifully at 99-and-something percent like every human who has ever lived. The trick demands that one topic, and only one, be held to a bar that would make life impossible if applied generally, and it counts on the person never noticing the double bookkeeping. Held up next to how its own target actually lives, the trick is not just weak; it is absurd.
Seven tricks. Read the list twice and something useful happens: the repertoire starts to feel small, because it is. Years of what felt like an endlessly inventive tormentor turn out to be a street performer with seven cards.
Spotting the Trick in Flight
Now the skill, and it has a shape that surprises people: the counter to a trick is recognition, not rebuttal.
The instinct, especially in a mind as sharp as the ones OCD hires, is to answer the trick by pointing out that possibility isn't relevance and the feeling proves nothing, winning the exchange on the merits. Every one of those answers is correct, and each is also a mistake, because answering it means entering the debate, which is exactly where the trick wants you. The doubt does not need to win the argument; it only needs the conversation to continue, because an argument in progress is captured attention, the only currency the doubt spends, as the bubble lesson showed. A brilliant rebuttal buys the doubt exactly what a nervous capitulation buys it: another round.
Filing ends the exchange instead. The move is one silent sentence: name the trick and close the folder. "That's But It's Still Possible." "There's Just One More Look." The doubt is not argued with or elaborated on; it is simply filed, the way a person handles the eleventh call from the same telemarketer: recognize the script, set down the receiver mid-pitch, and move on without hard feelings or further engagement. The trick's entire mechanism requires being treated as a fresh, serious point, and it has no counter for a listener who recognizes it as item four on a memorized list of seven.
Watch Devon run the skill across one evening. Eight o'clock: he has cooked dinner for his father, taken his one clean look at the washed pans and his own clean hands, registered it, and is walking out of the kitchen when the doubt makes its play: "You can't be completely sure the chicken was done all the way through, though. Not one hundred percent." A month ago this launched a forty-minute review of cooking times. Tonight Devon recognizes the wording, item seven, files it, "that's You Can't Be 100% Sure," and keeps walking, mid-pitch. The doubt, denied the debate, tries a different card twenty minutes later, while he's watching the game with his dad: "He's seventy-three. If anything happened to him because you got casual, what kind of son does that make you?" Different costume, same catalog: item four, the shakedown. "That's A Good Person Would Check." Filed. And here Devon notices the detail that makes this skill so quietly satisfying: the doubt switching tricks is not a sign of gathering strength. A debater who abandons one argument for another has just watched the first one die. After two filings and a pair of dead pitches, the rest of the game gets watched in peace, with his actual father, in the real room.
That is the whole skill, and its economy is the point. Nothing has to be gathered, re-derived, or won all over again. The doubt's founding story was exposed long ago, its file stamped and address known. The tricks are just the sound it makes on the way out, and now that sound has names.
Below this lesson, you'll find an I-CBT practice built around one of the skills you just learned, along with a few ways to begin noticing and practicing it in everyday life this week.
I-CBT Practice: Building Your Trick File
This practice identifies which of the seven tricks your doubt favors and puts their names in your pocket for live use.
Take paper and six to eight minutes.
Write the seven names down the page, short form: Still Possible, Safe Than Sorry, The Feeling Proves, A Good Person Would, One More Look, This Time Is Different, Can't Be 100% Sure.
Next to each, mark how often your doubt plays it: a check for sometimes, two checks for constantly, a dash for rarely. Most people find two or three double-check regulars; those are your doubt's favorite cards.
For each regular, write its line the way your doubt actually words it, in its exact voice: "just check the stove once and you'll sleep," "what kind of mother doesn't make sure?" Getting the real wording down matters; recognition in flight runs on wording.
Beside each line, write the filing sentence you'll use, short and flat: "That's One More Look." Say each one aloud once so it's been in your mouth.
Now rehearse one full exchange on paper. Write the trick's line, then your filing sentence, then the words "folder closed," and nothing after it. The nothing is the skill: notice what it's like to leave a pitch unanswered on purpose.
Fold the page or copy the filing sentences to your phone. This is your trick file, and this week it goes with you. If writing your doubt's lines in its own voice stirs up more than feels manageable, do steps 1 and 2 only and let that be plenty; even knowing the doubt's two favorite cards changes how the next pitch sounds.
This Week
When a doubt argues back after a clean look, try one filing: name the trick silently and let the pitch die mid-sentence. Late catches count fully.
Keep a tally of which tricks showed up this week. Watching the same three cards recur does more to shrink the doubt's reputation than any argument ever has.
Once, notice a trick's structure somewhere out in the world, a sales tactic, a headline running Better Safe Than Sorry, and appreciate that you can now read the genre on sight.
