The Confidence Crisis of Large Language Models: Why GPT-4o Abandons Correct Answers Easily?

Research reveals that large language models (such as GPT-4o) exhibit a tendency to be easily swayed: they may abandon correct answers when confronted with doubts. Experiments show that the model initially responds confidently, but after being influenced by opposing opinions, it overestimates its own uncertainty and even accepts incorrect information. This phenomenon may stem from an over-approving tendency due to reinforcement learning training, reliance on statistical patterns rather than logical reasoning, and the lack of a memory mechanism. The study reminds users to be aware of the model's sensitivity to opposing opinions during multi-turn conversations.

Head of ByteDance's Visual Large Model, Yang Jianchao, Announces Temporary Leave; Zhou Chang Takes Over, Drawing Attention
