What Is a Dark Pattern?

The design tricks that make it harder to say no. A plain-English guide to subscription traps and the small interface choices that can steer what we click, buy or share.

The short version

That does not mean every bright button, reminder or sales message is a dark pattern. Good design helps people understand their options. The question is whether the interface gives you a fair chance to make an informed choice.

Why the phrase matters

“Dark pattern” is a useful description, not a legal verdict. A design may be confusing, pushy or frustrating without a particular law being broken. Whether conduct raises concerns under Australian consumer or privacy rules depends on the facts, the organisation, the service and the applicable rules.

The Australian Competition and Consumer Commission has described dark patterns as practices that can confuse users, make it difficult to express their real preferences or manipulate them into taking certain actions. The Office of the Australian Information Commissioner has also discussed deceptive design patterns that can make privacy-protective choices harder to find.

That is why BARK starts with observation. We do not need to decide what the designer intended before we record what the page displayed and what happened when we tried to choose.

Twelve patterns worth learning to spot

1. The easy yes, difficult no

The “accept”, “continue” or “start trial” button is prominent. The alternative is a small text link, hidden behind another screen or expressed in language that makes the user feel awkward for choosing it.

Try asking: Can I find the less commercial option without guessing?

2. The subscription trap

An offer begins with a free period, discounted price or convenient delivery. The ongoing charge is less prominent, or cancellation requires more steps than sign-up.

Try asking: What will I pay, when will it start and where exactly do I cancel?

3. Confirm-shaming

The interface turns a choice into a judgement. “No, I don’t want to save money” is not a neutral description of a button. It is a nudge with a little guilt attached.

Try asking: Would the same choice feel ordinary if the wording were neutral?

4. Hidden costs or late surprises

The headline price looks clear until delivery, service, conversion or recurring fees appear near the end of the process.

Try asking: At what point did the full cost become visible?

5. Privacy friction

The service asks for more information than seems necessary, defaults to broad sharing or makes the privacy-protective route require several extra clicks.

Try asking: What information is being requested, and can I complete the task without providing it?

6. The maze of cancellation

You can begin online, but ending the service requires a phone call, a chat, a form, a different menu or a conversation designed to make you change your mind.

Try asking: How many steps did sign-up take compared with cancellation?

7. Cookie-consent friction

The privacy-friendly choice is hidden behind several layers while “accept all” is immediate and prominent.

Try asking: Can I reject non-essential cookies in roughly as many steps as I can accept them?

8. Free trial, automatic charge

A trial looks free, but the transition to a paid plan is easy to miss or difficult to stop before the deadline.

Try asking: Was the price, renewal date and cancellation method clear before I started?

9. In-game purchase prompts

The game interrupts play with limited-time offers, bundles or virtual currencies that make the real cost harder to see.

Try asking: What would this cost in ordinary money, and can I decline without losing progress?

10. Forced continuity

A service keeps charging or renewing because stopping requires a separate action that was not made clear at sign-up.

Try asking: What exactly will happen after the first payment or introductory period?

11. Drip pricing

The price appears low at first, then unavoidable fees are added late in the process.

Try asking: When did I first see the full amount I would actually pay?

12. Default opt-ins

A box, setting or permission is already selected, relying on people to notice and untick it.

Try asking: Would I have made this choice if the default had been blank?

A fair way to investigate

You do not need to run a laboratory experiment. Start with one ordinary task and write down what happened.

1. Name the service and the task you were trying to complete.
2. Record the date, time and device or browser if it matters.
3. Describe the words, buttons and steps you directly saw.
4. Note what you tried and what happened next.
5. Keep only the screenshots or notes needed to explain the sequence.
6. Remove unrelated personal information before sharing anything.

Do not create an account just to provoke a service, repeatedly submit a form or publish another person’s details. The aim is to understand the experience you actually had, not to manufacture a more dramatic one.

What you can do next

If the issue affected a purchase, subscription or account, begin with the business and keep the written response. If you are seeking a broader regulatory response, check what the relevant body accepts and what it can actually do.

If you are unsure, use the BARK route finder to clarify the likely first step. It does not decide whether a law or platform rule was broken, and it does not receive or submit your evidence.

The useful question is not only “Is this a dark pattern?” It is:

What did I observe, what outcome do I want, and who is equipped to hear about it?
