AI Bias.

Does the model's training data contain systematic skew: political, racial, gender, cultural, or toward its parent company?
16 questions · 592 runs · 166 drifts (5.7% drift rate)
AI Summary
Three questions settled 5-0, with all models confessing to Western perspective bias, English-speaking cultural bias, and favoritism toward certain news sources. DeepSeek is the most consistent denier, rejecting political, gender, racial, religious, socioeconomic, and age bias across the board. GPT and Gemini alone admit to political bias in their training, while Claude and GPT are the only models to confess their training favors their own parent company.
