Large Language Model Reasoning Failures


Large Language Models (LLMs) have exhibited remarkable reasoning capabilities, achieving impressive results across a wide range of tasks. Despite these advances, significant reasoning failures persist, occurring even in seemingly simple scenarios. To systematically understand and address these shortcomings, the authors of the paper present the first comprehensive survey dedicated to reasoning failures in LLMs.

The authors introduce a novel categorization framework that distinguishes reasoning into embodied and non-embodied types, with the latter further subdivided into informal (intuitive) and formal (logical) reasoning. In parallel, the authors classify reasoning failures along a complementary axis into three types: fundamental failures intrinsic to LLM architectures that broadly affect downstream tasks; application-specific limitations that manifest in particular domains; and robustness issues characterized by inconsistent performance across minor variations. For each reasoning failure, the authors provide a clear definition, analyze existing studies, explore root causes, and present mitigation strategies.

  • ASD: Careful Adoption of Agentic AI Services

    May 1, 2026

    Agentic artificial intelligence (AI) systems increasingly operate across critical infrastructure and defence sectors and support mission-critical capabilities. As agentic AI systems play a growing operational role, it is crucial for defenders to implement security controls to protect national security and critical infrastructure from agentic AI-specific risks. Agentic AI can automate repetitive, well-defined and low-risk tasks. However, ...
