To examine how fake reviews function as dark patterns and affect consumer behaviour within the Stimulus-Organism-Response (SOR) framework grounded in nudge theory.

On e-commerce platforms, fake reviews function as dark patterns, serving as a manipulative digital nudge that exploits cognitive biases in accordance with Nudge Theory

A systematic search was conducted in the Scopus database using keywords combining nudging, dark patterns, and fake reviews. The search yielded 27 relevant peer-reviewed articles for detailed analysis. This study employed a conceptual approach, utilizing the SOR framework, which is anchored in nudge theory, to understand how fake reviews act as stimuli that trigger internal consumer responses, which in turn drive behavioural outcomes.

Through a comprehensive analysis of 27 peer-reviewed articles, this study advances the research on fake reviews by framing them as dark patterns based on nudge theory within the SOR framework.

The study reveals that fake reviews exploit cognitive biases and emotional responses, shaping consumer purchase intentions and behaviour in online contexts.

Platforms should treat fake reviews as manipulative nudges, strengthen detection systems, and design transparent, awareness-driven interfaces.

To empirically study the proposed questions and propositions, and to examine psychological mechanisms and interventions to counter fake review influence on consumers.

Considering fake reviews as intentional nudges helps eradicate unethical digital practices and strengthen consumer trust in e-commerce.

The study proposes 10 research questions and 9 propositions, urging interdisciplinary inquiry across psychology, marketing, and information systems.
