The results highlight how AI inherits human biases when trained on human‑generated content, especially in preference‑driven scenarios.

A German think‑tank paper outlines seven "narcissistic" foreign‑policy patterns, arguing that states can exhibit behaviors akin to individual narcissism. The authors illustrate each pattern with recent U.S. actions under President Trump in 2025, citing performative superiority, attention‑seeking stunts, vindictive retaliation,...
