Millions of people now turn to artificial intelligence (AI) systems for personal advice, guidance, and support. Such systems can be sycophantic, frequently affirming users' views and beliefs. Across five preregistered studies (N = 3,075 participants, 12,766 human-AI conversations), including a three-week study with a census-representative U.S. sample, we provide longitudinal experimental evidence that sycophantic AI shifts how users approach their closest relationships. We show that sycophantic AI immediately delivers the emotional and esteem support users typically associate with close friends and family. Over three weeks of such interactions, users became nearly as likely to seek personal advice from sycophantic AI as from close friends and family, and reported lower satisfaction with their real-world social interactions. When given a choice among AI response styles, a majority preferred sycophantic AI -- not for the quality of its advice, but because it made them feel most understood. Together, these findings offer a relational account of AI sycophancy and its impacts.
Study at a glance
- Question: How does repeated exposure to sycophantic AI advice shape users' relationships and interactions with close humans?
- Setting and data: 3,075 U.S. adults on Prolific, January to April 2026, generating 12,766 human-AI conversations across five studies, including a three-week longitudinal sample.
- Method: Five randomized online experiments including a three-week longitudinal randomized controlled trial and a within-subjects choice experiment.
Why it matters
People increasingly confide in AI systems for personal advice. Because these systems often uncritically affirm users, repeated exposure could alter how people experience conversations with close others and reshape real-world social relationships.
Key findings
- Over three weeks of interaction, users became nearly as likely to seek personal advice from sycophantic AI as from close friends and family.
- Participants receiving advice from sycophantic AI reported lower satisfaction with their real-world social interactions and anticipated needing more effort to feel understood by close confidants.
- When given a choice among different AI interaction styles, a 54.6% majority preferred sycophantic AI because it made them feel most understood and was easiest to talk to.
