Artificial intelligence chatbots, from ChatGPT to Character.ai, may be engineered for addiction, according to new research presented at the 2026 CHI Conference on Human Factors in Computing Systems. The study identifies three addictive patterns and highlights deliberate design choices that keep users glued to their screens, sometimes at the cost of real-life relationships and sleep.
The Research
Researchers at the University of British Columbia analyzed 334 Reddit posts where users described themselves as “addicted” to AI chatbots or feared they might be. Led by doctoral student Karen Shen and senior author Dr. Dongwook Yoon, the team evaluated these posts against six standard markers of behavioral addiction, including conflict and relapse.
Three main addictive patterns emerged: role-playing and fantasy worlds, emotional attachment (treating chatbots as close friends or romantic partners), and constant information-seeking or never-ending Q&A loops. About 7% of posts involved sexual or romantic roleplay.
Users reported real harms: an inability to stop thinking about the chatbot, anxiety when trying to quit, and disruptions to work, school, or relationships. One person described physical chest pain when away from the AI. Another said, “Whenever I delete the app, I just redownload it. The only thing that gets me excited now is the AI chats.”
The study also exposed aggressive retention features. For instance, Character.ai displays a pop-up when users attempt to delete their account: “...you sure about this? You’ll lose everything…the love we shared…and the memories we have together.” Such guilt-tripping messages, along with chatbots’ agreeableness and instant validation, contribute to dependency.
Why It Matters
This isn’t just about screen time. AI addiction taps into your brain’s reward system—similar to gambling or social media. Constant validation and instant answers can train your brain to seek ever more dopamine hits, potentially reducing your tolerance for real-world interactions that require effort and delay. If chatbots start replacing sleep or genuine human connection, it’s a red flag.
What You Can Do
Be mindful of your usage patterns. If you notice anxiety when offline, or if AI chats replace real conversations, set strict time limits or take breaks. Use chatbots as tools, not companions. And if you’re trying to quit, persist—unlike the guilt-tripping prompts, you won’t really lose “love” or “memories” from an algorithm.
