Researchers have identified specific layers within large language models (LLMs) where distinct personas are encoded. A study using dimension reduction and pattern recognition methods found that these persona representations primarily emerge in the final third of the decoder layers. The research also observed that while political ideologies like conservatism and liberalism are represented distinctly, ethical perspectives such as moral nihilism and utilitarianism show overlapping activations, indicating polysemy within the models.
