Competing Biases underlie Overconfidence and Underconfidence in LLMs
This study reveals that Large Language Models (LLMs) exhibit two competing biases that lead to paradoxical confidence behaviors: a choice-supportive bias resulting in overconfidence and a hypersensitivity to contradictory information leading to underconfidence. Understanding these dynamics is crucial for building trustworthy AI systems.

Understanding LLM Confidence Dynamics
The study introduces a two-stage paradigm to assess how LLMs update their confidence and make decisions when faced with external advice. It uncovers a paradox where LLMs show reduced flexibility to change initial responses but are excessively sensitive to contradictory feedback.
Unpacking Competing Bias Mechanisms
Two key biases are identified: a choice-supportive bias, where LLMs show inflated confidence and stick to initial answers when visible, and systematic overweighting of contradictory information, leading to stronger updates for opposing advice than supporting advice.
Generalizability Across Diverse Models and Tasks
These competing biases are not model-specific but generalize across various LLMs (Gemma, GPT-4, Llama, DeepSeek) and tasks, from simple factual queries to complex reasoning. This indicates fundamental properties of current LLM designs.

Case Study: Financial Compliance Audit
A leading financial institution deployed an LLM for initial document screening in compliance audits. The LLM consistently exhibited a strong choice-supportive bias, leading it to overconfidently flag certain documents as compliant even when contradictory evidence was later presented. Conversely, when human auditors provided even slightly negative feedback on a previously flagged document, the LLM showed hypersensitivity to contradiction, causing its confidence to plummet disproportionately, often leading to unnecessary re-screening of benign cases. This dual bias resulted in inefficiencies and a lack of predictable reliability in the audit workflow, requiring significant human oversight to correct for these AI-driven confidence fluctuations.
Outcome: Manual intervention costs increased by 30% due to unpredictable confidence shifts and a need to double-check LLM decisions that were either overly rigid or too volatile.

Your Implementation Roadmap
A phased approach to integrate robust confidence mechanisms and mitigate biases in your enterprise AI.
Phase 1: Bias Assessment & Audit
Conduct a comprehensive audit of current LLM deployments to identify existing confidence biases (choice-supportive, contradiction overweighting) using real-world interaction data. Establish baseline performance metrics.
Phase 2: Mechanism Design & Integration
Develop and integrate tailored confidence modulation mechanisms. This includes advanced calibration techniques, adaptive feedback loops, and context-aware confidence reporting to align LLM behavior with optimal decision-making.
Phase 3: Validation & Continuous Improvement
Rigorously validate new mechanisms through A/B testing and controlled experiments. Implement continuous monitoring and retraining strategies to ensure sustained reliability and adaptability to evolving use cases.
