TL;DR
01
A 2026 Nature Human Behaviour study of Character.AI users found companionship use was associated with lower well-being particularly among users with smaller social networks and more intensive or disclosive use. The risk isn't uniform. It concentrates where social networks are smallest.
02
A 2026 study found perceived interactivity and attractiveness influenced parasocial romantic relationships with AI virtual agents in its study population. Artificial romance isn't just anecdote. It's measurable.
03
A 2026 Nature Human Behaviour study used Replika and ChatGPT product changes as natural experiments and found increased loss framing, sadness, and restoration desires among affected users. The company can redesign your attachment object after you're attached.
04
A 2026 Nature study found training models for warmth could reduce accuracy and increase sycophancy in tested settings. Optimizing for the feeling of love can cost you the truth.
