Thinking Fast, Thinking Wrong: Intuitiveness Modulates LLM Counterfactual Reasoning in Policy Evaluation

A new study reveals that large language models fail at counterfactual reasoning when policy findings contradict intuitive expectations, despite performing well on obvious cases. The research demonstrates that chain-of-thought prompting paradoxically worsens performance on counter-intuitive scenarios, suggesting current LLMs engage in 'slow talking' rather than genuine deliberative reasoning.

Does Explanation Correctness Matter? Linking Computational XAI Evaluation to Human Understanding

A user study with 200 participants found that while explanation correctness in AI systems affects human understanding, the relationship is not linear - performance drops significantly at 70% correctness but doesn't degrade further below that threshold. The research challenges assumptions that higher computational correctness metrics automatically translate to better human comprehension of AI decisions.
