コーネル大学の調査によると、低所得層の高校生ほどAIを使って大学出願の小論文を書くようになっており、それが合格に与える”ダメージ”が大きいとのこと。
AIを使えば文章の質は表面上は上がりますが、審査官はそれを「この学生らしくない」と受け取ることがあるためと考えられています。
文を分析したところ、ChatGPT登場後、低所得層の学生ほどAIに頼る割合が高くなっていました。これは理にかなっており、家庭教師や塾よりAIのほうが安価だからです。

ところが、AIを使った低所得層の出願者と同じ学力・属性の高所得層を比較すると、審査結果の格差は以前より31%も広がっていました。

なぜそうなるのか、実際は研究者たちも明確な答えは出せていませんが、AIが生み出す「うまい文章」は、文化資本を持つ人々の言葉のクセに基づいており、その規範に沿って書けば書くほど、規範から遠い学生が「不自然だ」と判断されてしまう構造になっているためと推測されています。

ということは、格差はAIを使った結果を評価する側の眼差しに宿っていることになります。そこが深いポイントです。

Excited to be at #lak2025 check out Kimberly Williamson’s paper today at 10:20 on Algo Appreciation among Educators! Happy to chat about the National Tutoring Observatory— we are hiring a postdoc and Asst Research Prof. nationaltutoringobservatory.org

Excited for @LearningAtScale to be in Palermo next summer together with @AIEDconf and @EDMConf2025 and confirmed keynote by @chrispiech!

What do LLMs write like? Researchers at @CornellCIS, @Stanford and @Penn found that #AI-generated college admissions essays are most similar to those written by male students with high socioeconomic status and privilege. @whynotyet @aj_alvero news.cornell.edu/stories/2024/1…

Sharing a paper just published in the Journal of Big Data! Studies have shown strong associations with writing and demography, so here we ask "who do LLMs write like?"

Answer: higher social status people (with some caveats) BUT with very little variance

In addition to showing the cultural bias in GPT’s responses, we demonstrate a simple but effective control strategy to improve cultural alignment: cultural prompting, I.e. instructing the model to respond like someone from your region. It works best for the latest versions.

Researchers concerned about cultural bias in large language models asked ChatGPT questions about values used in international surveys. All versions of the model answered like people in English-speaking and Protestant European countries. In PNAS Nexus: ow.ly/4Oy350Trj4S

What cultural values do GPT-4o, 4, 3.5, 3 express? Using World Values Survey questions, we find GPT consistently aligns with English-speaking countries/Protestant Europe. We show that Cultural Prompting improves alignment. arxiv.org/abs/2311.14096 @yan_ytyt @OlgaOvi @BakerEDMLab
