Dark patterns are interface designs that steer people into a choice they would not make if the options were laid out plainly. The person ends up paying for something, staying subscribed, or sharing data because the interface made the other path harder, quieter or more embarrassing.

The term was coined as "dark patterns", and many writers now prefer **deceptive design (dark patterns)** or "deceptive patterns", since the point is deception rather than darkness. The reference catalogue, [deceptive.design](https://deceptive.design/types/), was itself formerly called Dark Patterns. This glossary uses both names.

## Why they convert, and why that is misleading

A dark pattern is almost always a response to a number. Trial-to-paid is flat, churn is up, attach rate on an add-on is low. Someone pre-ticks the add-on, moves the cancel link one screen deeper, or adds a countdown, and the number moves within a week.

What the dashboard does not show is where the cost lands. It lands later and somewhere else: refunds, chargebacks, support tickets, one-star reviews, accounts that churn at the first renewal instead of the trial end. In B2B the cost is larger, because the person who felt tricked at checkout is often the person who decides on next year's renewal and the seat count.

This is why the line is practical as well as ethical, as the [growth design](https://www.themasterly.com/glossary/growth-design) entry puts it: a change judged on this week's conversion invites every pattern below, and the same change judged against [retention](https://www.themasterly.com/glossary/retention) and refunds a month later usually fails.

## The named patterns and their honest alternatives

| Pattern | What it looks like | Honest alternative |
|---|---|---|
| [Confirmshaming](https://www.themasterly.com/glossary/confirmshaming) | "No thanks, I don't want to grow my team" | A neutral decline: "Not now" |
| [Roach motel](https://www.themasterly.com/glossary/roach-motel) | Sign up in two clicks, cancel only via a call | Cancel where you signed up, in about as many steps |
| [False urgency](https://www.themasterly.com/glossary/false-urgency) | A timer that resets, "Only 2 seats left at this price" | Real deadlines and real limits, stated plainly |
| [Drip pricing](https://www.themasterly.com/glossary/drip-pricing) | Platform fee and minimum seats revealed at the last step | The total price on the pricing page |
| [Forced continuity](https://www.themasterly.com/glossary/forced-continuity) | Trial converts to paid with no reminder | A reminder before the first charge, and the date visible in the product |
| [Preselection](https://www.themasterly.com/glossary/preselection) | Paid add-ons pre-ticked, priciest plan defaulted | Paid extras unticked; defaults that serve the user |

Other catalogues add more: fake social proof, nagging, trick wording, disguised ads, comparison prevention. The six above are the ones most likely to appear in a SaaS signup, billing or cancellation flow.

## Where regulators have drawn lines

This is a summary of public sources, not legal advice, and the details change.

**In the EU**, the [Digital Services Act, Article 25](https://eur-lex.europa.eu/eli/reg/2022/2065/oj) bars providers of online platforms from designing interfaces that deceive or manipulate users or materially impair their ability to make free and informed decisions (micro and small enterprises are exempt unless designated as very large platforms). It applies to online platforms specifically, and it does not apply to practices already covered by the Unfair Commercial Practices Directive or the GDPR. Two consumer-law rules matter most here: the [Unfair Commercial Practices Directive](https://eur-lex.europa.eu/eli/dir/2005/29/oj) lists false "only available for a very limited time" claims as unfair in all circumstances, and the [Consumer Rights Directive, Article 22](https://eur-lex.europa.eu/eli/dir/2011/83/oj) requires express consent for extra payments and entitles consumers to a refund where consent was inferred from a pre-selected default.

**In the US**, the FTC's 2022 staff report [Bringing Dark Patterns to Light](https://www.ftc.gov/news-events/news/press-releases/2022/09/ftc-report-shows-rise-sophisticated-dark-patterns-designed-trick-trap-consumers) describes fake countdown timers, hard-to-cancel subscriptions, hidden fees and manipulative privacy defaults. For online subscriptions, the [Restore Online Shoppers' Confidence Act](https://www.law.cornell.edu/uscode/text/15/8403) requires clear disclosure of material terms, express informed consent and a simple way to stop recurring charges. In California, the [CCPA as amended by the CPRA](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV&sectionNum=1798.140) defines dark patterns and states that agreement obtained through them is not consent.

Much of this protects consumers rather than businesses, so a B2B product may sit partly outside it. California's privacy law is the exception: it covers individual California residents, including people acting for a business. The line is thinner for self-serve plans bought by individuals on a card, and it is not one to rely on without advice.

## In practice

A product team is asked to cut churn by a quarter. The quickest lever is the cancellation flow, and the first proposal is to remove the cancel button from settings and route everyone to a "talk to us" form.

The alternative that ships instead keeps cancellation in settings and adds two things in front of it: a single question about why, and, depending on the answer, a relevant offer. "Too expensive" sees a smaller plan. "Not using it right now" sees a pause. "Missing a feature" sees nothing but a note that the answer has been passed on.

Cancellations still happen, at a lower rate than before, and the reasons become the most useful research input the team has. The version that hid the button would have cut the number faster and filled the support queue with people who now distrust the product.

## Where teams get it wrong

- **Reading the result too early.** The cost of a dark pattern arrives after the dashboard has moved on.
- **No guardrail metric.** Refunds, disputes and renewal rate belong next to conversion.
- **Copying consumer tactics.** B2B buyers come back to renew, and they remember.
- **Assuming B2B means out of scope.** Self-serve plans blur the consumer line.
- **Treating the honest version as weaker.** It moves the number less on day one and keeps it moved.

## FAQ

**What are dark patterns?**

Interface designs that steer people into a choice they would not make if the options were laid out plainly: a purchase, a subscription, a consent, a harder exit. Many writers now call them deceptive design patterns, which describes the problem more precisely. The defining feature is that the design works against the person using it.

**Why do teams ship dark patterns?**

Because they work in the short term and are measured in the short term. A pre-ticked add-on or a buried cancel link moves this month's conversion or churn number, and nobody on the team has to decide to be manipulative for it to happen. It only takes a metric read too early and no guardrail downstream.

**Are dark patterns illegal?**

Some specific practices are, in some places. EU consumer law lists false limited-time claims as unfair and entitles consumers to a refund for extras charged through pre-ticked defaults, US law requires clear terms, consent and a simple way to stop recurring charges for online subscriptions, and California treats agreement obtained through dark patterns as no consent for privacy purposes. Scope varies, much of it protects consumers rather than businesses, and none of this is legal advice.

**Do dark patterns work in B2B SaaS?**

They move the same short-term numbers and cost more afterwards. B2B buyers renew, expand seats, sit on review sites and talk to peers, and the person who felt tricked at checkout is often the person who signs the renewal. A manipulative cancellation flow tends to show up later as disputed invoices and a worse renewal conversation.

**What is the alternative to a dark pattern?**

The same goal pursued in the open. If the goal is fewer cancellations, offer a pause or a downgrade and ask why people leave. If it is more upgrades, show the real value and the real price. Honest versions usually move the number less on day one and keep it moved.
