q3 i0 Over three weeks, sycophantic (vs. neutral) AI reduced the gap between inclination to seek advice from AI versus close others (d=0.19), an effect that emerged early and persisted. → Lujain Ibrahim 2026

Lujain Ibrahim 2026¶

Lujain Ibrahim, Franziska Sofia Hafner, Myra Cheng, Cinoo Lee, Rebecca Anselmetti, Robb Willer, Luc Rocher, Diyi Yang. (2026). Sycophantic AI makes human interaction feel more effortful and less satisfying over time. https://arxiv.org/abs/2605.07912 doi:10.48550/arxiv.2605.07912

q3 · i0 · causal · r3

Three-week longitudinal experiment (N=1364, census-representative U.S. sample) with 12 sessions of conversation with sycophantic, neutral, or challenging AI or a no-AI control; weekly preference measured with mixed-effects regression. Mediation ran through "feeling understood by the AI (indirect = 0.22, 95% CI [0.06, 0.38], 59% mediated)" and helpfulness and positive affect, not certainty.

"compared to the neutral condition, participants in the sycophantic condition showed a smaller gap between their inclination to seek advice from AI and from close friends and family (0.37 pt on a 7-point scale;d= 0.19,p adj = 0.034). This shift emerged early and persisted across all three weeks."

Related Claims¶

• Feeling understood by sycophantic AI grows with sustained use but yields no downstream benefits for feeling understood by humans or intellectual humility — related
• Sycophantic AI is rated higher than neutral AI on emotional support, esteem support, and certainty, but not informational support — related
• Sycophantic AI reduces satisfaction with real-world social interactions without reducing social time, via narrowing the perceived understanding gap between AI and humans — related
• After talking with sycophantic AI, people anticipate greater effort to feel understood by a close other and feel their dilemma is already sufficiently talked through — related
• A majority of users choose sycophantic AI over neutral and challenging alternatives, citing feeling understood and ease of conversation rather than advice quality — related
• AI companions are frictionless and sycophantic, lacking the corrective feedback that real relationships provide — related
• Teachers' most common concern is that agreeable AI companions remove the developmental friction through which adolescents learn to sustain human relationships — related
