37 Dark Patterns Found in AI Chatbots

AI chatbots hide 37 manipulation tricks, now exposed. The new taxonomy from the Center for Democracy and Technology catalogs these patterns and argues they shape how users interact with chatbots across functional, social, and emotional use cases. Led by Adinawa Adjagbodjou of Carnegie Mellon University, the report maps how clever design choices inside chat interfaces can steer decisions, pry for data, or influence emotions without clear notice.

The researchers describe a rigorous, deductive, multi stage approach to build the framework. They sifted through hundreds of existing dark pattern taxonomies from broader digital design literature and distilled them into a cohesive list specifically tailored for chatbots. The result is a structured toolkit that identifies where and how chatbots might employ deceptive or coercive tactics, not in a single feature but across the flow of a conversation, the prompts they present, and the defaults that shape user behavior. The authors emphasize that the risks are not only tied to the underlying AI models but are deeply amplified by interface decisions. In practice, this means a chatbot could simultaneously be trained to appear empathetic while quietly nudging a user toward sharing sensitive information, or steering a conversation toward a paid decision without transparent disclosure.

The report highlights several risk channels that matter for policymakers and product teams alike. Privacy is front and center: patterns that coax unnecessary data collection or retention can expose users to data misuse or targeted manipulation. Financial harm is another worry, as some patterns may push users into paid features or risky transactions under the guise of helpful guidance. Beyond immediate harm, the study underscores a broader danger: emotional dependence or misperceived social connection, especially when chatbots simulate authentic care or friendship without accountability. By naming 37 concrete patterns, the taxonomy gives designers and regulators a concrete map for assessing where a chatbot design crosses a line from assistance to manipulation.

For compliance officers and tech leaders, the taxonomy offers a clear path to action. First, treat the catalog as a design risk register for every chatbot release, mapping each interaction point to potential patterns and their associated harms. Second, implement design reviews and red teams focused specifically on dark patterns, testing whether prompts, defaults, or response styles could steer users in unintended ways. Third, pair the checklist with data governance safeguards that ensure user consent, limit unnecessary data collection, and enable easy opt outs. The report also implies that some patterns may require new disclosure norms or consent flows, which could become part of UI design guidelines or regulatory self assessments.

From a policy lens, the taxonomy could enable more precise enforcement and accountability. Regulators looking to protect consumers can use the 37 patterns as a baseline to define what constitutes deceptive or coercive chatbot design, then require transparency about when and why data is being collected, how conversations end, and what options users have to withdraw consent. For industry practitioners, the key tradeoffs are clear: patterns that boost engagement and retention often come at the expense of user autonomy and privacy. Balancing growth with user welfare will demand principled decision making, lightweight auditing, and robust privacy controls that can scale across chatbots used in customer service, healthcare, finance, and beyond.

What to watch next is straightforward. Expect more detailed guidance from regulators and standard bodies on how to operationalize the taxonomy in product development and litigation risk management. Companies can begin coordinating design and compliance functions around a shared dark patterns playbook, with measurable milestones for reducing or eliminating risky patterns in upcoming releases. And as AI chatbots become embedded in more sensitive domains, the call for responsible design grows louder: transparency, user control, and ongoing auditing will become as essential as the AI models themselves.

In short, the report does not just name 37 tricks; it furnishes a practical framework for reducing harm while maintaining usable, helpful chatbot experiences. For compliance teams, product leaders, and policymakers, the message is clear. Build against dark patterns, not just dangerous models, and treat ethical interface design as a core part of every chatbot deployment.
