Dark Patterns, Deceptive Design, and the Law

Consumer Law and Policy | Book by Mark Leiser

Date & Time Tuesday, 24 February 2026 7:00-8:00 pm (HKT)
Duration 1:00
Location Online via ZOOM

This book provides essential insights on dark patterns and AI-powered deceptive design for anyone who wants to understand and challenge the pervasive influence of these hidden forces shaping our digital experiences.

These hidden design strategies – from personalised user interface triggers to sophisticated backend systems – are often used to manipulate user behaviour in ways that benefit businesses at the expense of users. With advanced profiling driven by AI, these deceptive techniques can tailor digital environments to each user, raising significant questions about privacy, control and the boundaries of digital design.
