Dark Patterns and the EU Digital Services Act: The Anatomy of Manipulative Interfaces
How interface design pushes users toward decisions against their interests, and why Article 25 of the DSA became the first to explicitly ban these practices in the EU.
If a nudge is a caring architecture of choice, then dark patterns are its evil twin: the same knowledge of behaviour, but deployed in the platform's interest rather than the user's.
From Brignull to a regulatory term
The term "dark patterns" was coined by designer Harry Brignull in 2010; today EU regulation uses the more neutral "deceptive design patterns" (deceptive.design). The essence is the same: the interface nudges the user toward a decision they would not make under a clear choice.
The taxonomy of Mathur et al.
The scale of the problem was measured at Princeton: a crawler went through roughly 11,000 online stores (~53,000 product pages) and found 1,818 instances of dark patterns, grouped into 15 types and 7 categories (Dark Patterns at Scale, ACM; preprint).
The anatomy of manipulation
The typical mechanics are recognisable: false urgency and countdown timers, "confirmshaming" (shaming the user for declining), pre-selected options, hidden costs, and obstructed subscription cancellation. All of them exploit predictable weaknesses of attention and inertia.
Article 25 of the DSA
Regulation (EU) 2022/2065 (the Digital Services Act), in Article 25(1), for the first time expressly prohibited online platform providers from designing interfaces in ways that deceive, manipulate, or otherwise distort users' ability to make free and informed decisions (EUR-Lex). Recital 67 describes dark patterns as practices that undermine autonomous choice.
From prohibition to practice
The DSA became directly applicable across the EU on 17 February 2024, and Article 25(3) instructs the European Commission to issue guidance on specific practices — the excessive prominence of certain options, repeated requests to reconsider a choice already made, and making unsubscribing more difficult than subscribing (European Commission).
The limits of regulation
A prohibition is only the beginning: enforcement runs up against the difficulty of proving "distortion" and the speed with which design adapts. The debate is shifting toward a broader notion of "digital fairness," but the principle is already established: a manipulative interface is not paternalism for the user's benefit but behavioural exploitation.

Запрет манипулятивных интерфейсов (DSA, ст. 25)
«Providers of online platforms shall not design, organise or operate their online interfaces in a way that deceives or manipulates the recipients of their service or in a way that otherwise materially distorts or impairs the ability of the recipients of their service to make free and informed decisions.»
Перевод: провайдеры онлайн-платформ не должны проектировать, организовывать или использовать свои интерфейсы так, чтобы обманывать или манипулировать пользователями либо иным образом существенно искажать или подрывать их способность принимать свободные и информированные решения.
