This paper aims to provide a novel framework for understanding the intricate relationship between dark patterns, consumer psychology, and purchase intentions. Utilizing the Buyer Black Box model, it aims to illuminate how manipulative design practices, known as dark patterns, function as social stimuli that influence consumer psychology and, in turn, shape purchasing behaviour. The paper proposes a novel conceptual framework that explicates the cause-and-effect relationship between dark patterns, consumer psychology, and purchase intentions. The findings demonstrate that dark patterns can significantly influence purchase decisions, leading to unplanned purchases. This highlights the urgency for ethical design practices and stricter global regulations to safeguard consumer autonomy and transparency online. This study lacked empirical testing, and the model overlooked broader factors like legal/ethical frameworks and user demographics, limiting its generalizability. This paper urges policymakers to recognize the harm of dark patterns and implement global safeguards for a fairer digital world.
