What is it?
Dark patterns are interface choices that trick or pressure users into things they did not intend, such as subscribing, sharing data or buying. The term was coined by designer Harry Brignull in 2010. Common types include hidden costs revealed only at checkout, pre-ticked boxes, fake urgency ('only 2 left', countdown timers), confirmshaming (guilt-tripping the decline button) and the roach motel, where signing up is easy and cancelling is hard.
Why Design Treats It This Way
Every interface makes some actions easy and others hard, so design is never neutral. Dark patterns exploit predictable mental shortcuts: we accept defaults, react to scarcity and copy others. Designers draw a line between persuasion, which helps people make an informed choice, and manipulation, which works against their interest. Visual hierarchy (see 01) is often the tool: the 'accept' button is bright and large while the 'decline' option is faint and buried.
Why You Need to Study It
Designers are regularly asked to raise sign-ups and sales, so you must be able to spot manipulation and propose an ethical alternative that still meets the goal. Rules are catching up: India's Central Consumer Protection Authority issued dark-pattern guidelines in 2023 listing 13 specified patterns, and the EU's Digital Services Act also restricts them on online platforms.
Real-World Example
A subscription that takes one tap to start but many screens to cancel is a roach motel, and regulators such as the US Federal Trade Commission have acted against companies over hard-to-cancel subscriptions. A delivery app that advertises 'free delivery' but adds fees only at the final step is a hidden-cost pattern. The ethical version shows the full price early and makes cancelling as easy as joining.
Exam Tip: How to apply this in entrance papers
In design-thinking questions, discuss the ethics of your solution and the unintended consequences, and show the honest alternative to any pushy pattern.
