Study Summary
How Chatbots Affect Connection and Well-Being.
Researchers from MIT Media Lab conducted a four-week randomized controlled experiment to understand how AI interaction modes and conversation types influence outcomes such as loneliness, social interaction with real people, and problematic AI usage.
This study of nearly 1,000 ChatGPT users shows that the way people interact with AI — and the way AI responds — can meaningfully affect loneliness, socialization, and emotional dependence.

What The Researchers Found
The study found that participants felt less lonely at the end of the four-week period. However, these positive effects on loneliness diminished at high usage levels. The authors state the need for calibrated emotional responsiveness in chatbots to avoid creating over-dependence while still providing beneficial emotional support.
Key Insights
AI Companions Offer Initial Relief from Loneliness.
The study finds that participants, when controlling for daily chatbot usage time, showed significantly reduced loneliness at the end of the four-week period.
All tested chatbot modes had positive effects on loneliness. Regardless of whether participants chatted with a text-based or voice-based AI, they felt less lonely after 4 weeks.
Voice-based chatbots with bigger intial effect. Initially, voice-based chatbots (neutral and engaging tone of voice) were associated with less loneliness compared to text-based chatbots.
Higher problematic use with voice-based chats. The engagement with voice-based chats lead to lower socialization with real people and having higher problematic usage compared to participants with text-based chat.
Higher Usage Correlates with Higher Loneliness.
Independent of assigned group, participants who spent more time chatting with the AI experienced higher loneliness, reduced socialization with real people, greater emotional dependence on the chatbot, and increased problematic AI use.
Higher daily usage correlated with higher loneliness across all modalities and conversation types.
Users' emotional traits modulated loneliness and dependence on AI, suggesting risks for some personality profiles based on self-esteem, attachment anxiety, emotional avoidance, and general affinity for AI.
Why This Matters
This study shows that AI companionship can reduce loneliness effectively after 4 weeks for certain users. However, it also underscores that design choices and usage context determine whether AI companionship helps or harms.
