Trick wording
What is the trick wording dark pattern?
Trick wording is a deceptive pattern that phrases a choice so confusingly that people do the opposite of what they intend. Double negatives, mismatched checkboxes, and deliberately ambiguous labels make the user trip - "uncheck this box if you do not want to not receive emails" - so that not reading carefully lands them where the company wants, not where they meant to go.

The demo
Your goal: you do not want marketing emails. Here's the preference control, two ways. Set it to match your wish in each - and see which one actually respects it.
What this demo shows (text version)
Your intention is fixed: you do not want marketing emails. The same preference control is shown two ways. The tricky version uses a confusing double-negative label - something like "untick the box if you would not prefer to not receive our emails" - so doing what feels right actually signs you up. The plain version says simply "Send me marketing emails" with a clear checkbox, so matching your intention is obvious.
That's trick wording: phrasing a choice so a quick reader does the opposite of what they mean. It exploits the fact that people skim, and it shows up around consent, marketing and cancellation. Honest design uses plain, positive, consistent language, so reading fast and understanding fully lead to the same outcome.
Trick wording weaponises confusing language so a careless reader chooses against their own interest. Double negatives, inconsistent checkbox meanings, and questions phrased so the obvious action does the opposite - all designed so skimming, which is how everyone reads, leads to the company's preferred outcome. It's a deception because it relies on people not parsing convoluted phrasing. The honest standard is plain, consistent, unambiguous language where the default reading matches what the user wants, and the easy path is the one they'd choose if they understood it perfectly.
Read quickly, the tricky version flips you into the opposite of what you wanted - that double negative did its job. The plain version says exactly what it does, so skimming and understanding land in the same place. That's the test of honest wording: a person reading fast should end up where they intended, not where the wording trapped them.
Trick wording exploits how people actually read - quickly, scanning, trusting that phrasing is straightforward. Double negatives ("don't not send me offers"), checkboxes that mean opposite things in the same list, and labels whose plain reading contradicts their effect all create a gap between what the user intends and what they click. The confusion is the mechanism, not a side effect.
It often hides around consent and marketing: email opt-ins and opt-outs, data-sharing toggles, cookie choices, and cancellation flows are common homes, because the company benefits when a confused user picks the "wrong" option. It pairs with confirmshaming and preselection, and frequently breaches consent rules that require choices to be clear and freely given.
The fix is plain language and consistency: phrase every choice positively and unambiguously, make checkboxes mean the same thing throughout, avoid double negatives entirely, and test wording with real users to confirm the plain reading matches the effect. If someone reading at normal speed can be steered into the opposite of their intent, the wording is doing manipulation, not communication.
