Hate to tell you this, but not every user is vulnerable: Dark Patterns, AI, & Digital Fairness Act

This lecture argues that digital vulnerability should not be treated as a permanent status of the online user. Instead, vulnerability is better understood as a relational and contextual condition produced when a person, a system, and a decision environment interact in ways that reduce autonomous choice. Drawing on Dark Patterns, Deceptive Design, and the Law, the lecture distinguishes ordinary persuasion from manipulation and exploitation, explains why the interface is only the visible part of deceptive design, analyses the limits of Article 5 of the EU AI Act, and argues that the Digital Fairness Act should regulate optimisation strategies that exploit vulnerability events rather than assuming either perfect rationality or permanent vulnerability. These notes identify the legal and book materials on which the script is grounded. They are included for revision, publication notes, and future metadata alignment. Book Chapter 6: AI-Powered Deceptive Design. Main anchors: the opening thought experiment about asking an AI system to maximise engagement or profitability; the treatment of adaptive AI, non-deterministic systems, Article 5(1)(a), material distortion, significant harm, and the shopping/financial/health app case studies. Book Chapter 7: The Illusion of Control: Who is Truly Vulnerable? Main anchors: layered vulnerability; the vulnerability cycle on p. 219; informational, psychological, and systemic vulnerability; Article 5(1)(b); and the recruitment, virtual therapy, and teen mental-health app case studies. EU AI Act Article 5: Article 5(1)(a) and 5(1)(b) prohibit certain manipulative, deceptive, subliminal, and vulnerability-exploiting AI systems where the cumulative statutory thresholds are met. European Commission guidelines on prohibited AI practices: Commission guidance on Article 5 was published to support the consistent application of the AI Act. It is non-binding; authoritative interpretation remains for the Court of Justice of the European Union. Digital Fairness Fitness Check: The Commission’s 2024 Digital Fairness Fitness Check evaluated core consumer law instruments and identified harmful evolving online practices, including dark patterns and other digital fairness challenges. Digital Fairness Act: Announced as a 2026 legislative initiative. Public-facing EU materials identify likely areas including dark patterns, addictive design, unfair personalisation, influencer marketing, subscription difficulties, and exploitation of consumer vulnerabilities.
