Do LLMs Keep Mental Accounts? Empirical Evidence from Hedonic Framing, Nonfungibility, and Sunk Cost Sensitivity

Persona-Aware Evaluation of Cognitive Bias in LLMs: From Benchmark to Applied Decision-Making

Human-like moral judgments conceal divergent motive attributions in large language models

Large language models (LLMs) are used to simulate human participants in psychological research. We asked whether LLMs that reproduce human evaluations of a whistleblower's moral character also reproduce the motive attributions that accompany them. Five LLMs and two human samples (N = 125 and N = 742) evaluated a physic...

Echoes of Deeds: Moral History Can Shape and Steer LLM Behavioral Choices

Evaluations of Large Language Models (LLMs) morality typically consider decisions in isolation, thus overlooking whether an individual's unrelated prior conduct influences the model's subsequent choices. This leaves open the question of whether, and to what extent, moral history shapes LLM decisional behaviors. Prior w...

How Model Choice and Memory Shape Preference Consistency in Large Language Models

When a language model answers a sequence of questions, researchers report the model and temperature but rarely what or how it was told about its own earlier answers. I show that this underreported setting behaves as a mode effect. Testing four large language model (LLM) families with revealed preference theory (GARP)...

Assessing mentalization in humans and large language models

Different capacities for mentalization across LLMs are demonstrated, and cognitive computational modeling is highlighted as a formal method for assessing comparative intelligence across humans and machines.

Navigating the digital spectrum: Assessing political bias, stability, and downstream fairness in Large Language Models

A robust Political Compass Test evaluation framework is introduced that samples 300 configurations across an eight-dimensional perturbation space varying language, framing, instructions, answer format, option order, and persona wording, and results show most models lean Libertarian-Left on average and larger models sho...
