Summary

Matti Nelimarkka, from the University of Helsinki and Aalto University, presents a mini-lecture on the worldviews embedded in large language models (LLMs) and their implications for social science research. He introduces the concept of Weltanschauung, drawing on Gabriel Abend’s work on theory, and argues that LLMs are not neutral tools but incorporate societal values and perspectives from training data. To illustrate this, he demonstrates fine-tuning a GPT-2 model with Marxist texts, showing how the model’s outputs shift in content and perspective. He also presents analyses using BERT-based models, including word embedding projections and topic modeling, to show differences between baseline and fine-tuned models. The talk includes a code walkthrough of the fine-tuning process using the Hugging Face library, emphasizing reproducibility. Nelimarkka concludes by highlighting the importance of reflecting on the worldviews embedded in LLMs when using them for social science research.

Critical Evaluation

Value of the Information & Strength of the Argument

The talk provides valuable insights into the non-neutrality of LLMs, supported by concrete examples of fine-tuning with Marxist texts. The argumentation is clear and logically structured, moving from theoretical concepts to practical demonstrations. However, the empirical evidence is limited and somewhat anecdotal, with the author acknowledging the weakness of some interpretations. The value lies in raising awareness and offering a methodological approach for examining worldviews in LLMs.

Scientific Rigor, Source Quality, Title Accuracy

The talk references academic literature, including Abend’s work on theory and studies on gender bias in language models, but does not provide specific citations or URLs. The code is available on OSF and linked in the paper, but the paper itself is not explicitly referenced. The title accurately reflects the content. The presentation is rigorous in its conceptual framework but lacks detailed source citations and formal peer-reviewed validation.
