Challenge: Large Language Models (LLMs) have the potential to exert substantial influence on public perceptions and interactions with information.
Approach: They examine how LLMs can learn and generalize ideological biases from their instruction-tuning data.
Outcome: The LLMs show a startling ability to absorb ideology from one topic and generalize it to even unrelated ones.

Biased LLMs can Influence Political Decision-Making (2025.acl-long)

Copied to clipboard

Challenge: Recent studies have found that biased LLMs can influence decisions in areas such as medical classifications and educational hiring.
Approach: They conducted two interactive experiments on partisan bias in large language models while completing tasks with either a biased liberal, biased conservative, or unbiased control model.
Outcome: The results show that prior knowledge of AI is weakly correlated with a reduction of the bias, suggesting that AI education can be crucial for mitigating bias effects.
Probing Political Ideology in Large Language Models: How Latent Political Representations Generalize Across Tasks (2025.findings-emnlp)

Copied to clipboard

Challenge: Large language models encode rich internal representations of political ideology, but it remains unclear how these representations contribute to model decision-making.
Approach: They apply inference-time interventions to steer a decoder-only transformer along learned ideological directions . they find that learned ideological representations generalize well to bias detection, but not as well to voting simulations .
Outcome: The proposed model steers a transformer along learned ideological directions . political bias detection, voting preference simulation and bias neutralization are tested .
Bias in the Mirror : Are LLMs opinions robust to their own adversarial attacks (2025.acl-long)

Copied to clipboard

Challenge: Existing work on large language models lacks robustness, highlighting the limitations of such models.
Approach: They propose a novel approach where two LLMs engage in self-debate to persuade a neutral version of the model.
Outcome: The proposed approach examines whether large language models are robust during interactions and whether they are susceptible to reinforcing misinformation or shifting to harmful viewpoints.

User Inference Attacks on Large Language Models (2024.emnlp-main)

Copied to clipboard

Challenge: a large amount of data written by humans is used to train and fine-tune large language models.
Approach: They propose to infer if a user's data was used to train an LLM by using example-level differential privacy.
Outcome: The proposed attacks are easy to employ and only require black-box access to an LLM and a few samples from the user.
Understanding the Effect of Model Compression on Social Bias in Large Language Models (2023.emnlp-main)

Copied to clipboard

Challenge: Large Language Models (LLMs) trained with self-supervision on vast corpora of web text fit to the social biases of that text, leading to representational harm.
Approach: They propose to use quantization and knowledge distillation to reduce the computational burden of LLMs to mitigate the effects of inappropriate social biases learned during pretraining.
Outcome: The proposed methods reduce the computational burden of large language models by reducing their size and complexity.
LLM Sensitivity Challenges in Abusive Language Detection: Instruction-Tuned vs. Human Feedback (2025.coling-main)

Copied to clipboard

Challenge: Existing studies show that instruction-tuned LLMs under-predict positive classes . however, they are overly sensitive and can be applied for abuse detection without fine-tuning .
Approach: They show that instruction-tuned LLMs tend to under-predict positive classes . they also show that label frequency in the prompt helps with the significant over-prediction .
Outcome: The proposed models under-predict positive classes in social media, whereas they are overly sensitive.
