AI 中文摘要
在线百科全书塑造政治观点及民主话语。2025年末发布的Grokipedia由大语言模型Grok编写，旨在提供无偏见替代维基百科的选择。本文对Grokipedia和维基百科进行大规模政治偏见研究，用四位大语言模型评判员分析1394对描述政府成员的文章在九个意识形态维度的中立性。发现包括Grok在内的所有评判员都认为Grokipedia不如维基百科中立，两者对政治家总体都有好感但针对不同意识形态群体。
英文摘要
Online encyclopedias shape political opinion and, through it, democratic discourse. In late 2025, Grokipedia was released, an encyclopedia written entirely by the LLM Grok. One motivation behind the project was to provide an unbiased alternative to Wikipedia, which has faced accusations of "left-wing" and "liberal" bias. But does an encyclopedia written by an LLM deliver greater neutrality, or does it simply embed a different ideology? We conduct a large-scale political bias study on Grokipedia and Wikipedia, analysing 1,394 article pairs describing members of government for neutrality along nine expert-coded ideology dimensions employing four LLM judges, Grok, Claude, Mistral, and DeepSeek. As the LLMs could themselves be biased, we also investigate patterns in their judgments. We find all LLM-judges, including Grok, to rate Grokipedia less neutral than Wikipedia. Both encyclopedias are rated as portraying politicians favourably overall, but towards different ideological groups. Grokipedia particularly favours economically right-wing politicians and penalises socially liberal ones, while Wikipedia is rated as favourably biased towards the latter.
