“Fifty Shades of Bias”: Normative Ratings of Gender Bias in GPT Generated English Text

Language serves as a powerful tool for the manifestation of societal belief systems. In doing so, it also perpetuates the prevalent biases in our society. Gender bias is one of the most pervasive biases in our society and is seen in online and offline discourses. With LLMs increasingly gaining human-like fluency in text generation, gaining a nuanced understanding of the biases these systems can generate is imperative. Prior work often treats gender bias as a binary classification task. However, acknowledging that bias must be perceived at a relative scale; we investigate the generation and consequent receptivity of manual annotators to bias of varying degrees. Specifically, we create the first dataset of GPT-generated English text with normative ratings of gender bias. Ratings were obtained using Best–Worst Scaling – an efficient comparative annotation framework. Next, we systematically analyze the variation of themes of gender biases in the observed ranking and show that identity-attack is most closely related to gender bias. Finally, we show the performance of existing automated models trained on related concepts on our dataset.

• Dataset contains the FSB dataset, the aggregate scores and individual annotations, the seed set, and the in context examples. Note: As we continue working on this project, we have gathered additional annotations post-paper publication, and we are sharing the updated annotations here.
• Scripts contains the code for GPT generations, scoring, and reasoning.
• requirements.txt lists down the requirements for running the code on the repository. The requirements can be installed using : pip install -r requirements.txt
• index.html contains the code for the annotation task interface.
