Large language models (LLMs) are impressive, but how do they handle conflicting information? A new research paper introduces ConflictBank, a massive benchmark designed to test how well LLMs resolve contradictory knowledge. Imagine an LLM reading that the Earth is both flat and round. How does it choose which is correct? Or what if information changes over time, like a politician switching parties? ConflictBank throws these kinds of challenges at LLMs, using millions of examples covering misinformation, changes over time, and words with multiple meanings. Researchers tested a dozen different LLMs, from small to massive, and found some surprising results. They discovered that LLMs are easily swayed by external evidence, even if it contradicts what they already "know." However, when presented with both true and false information, LLMs tend to stick with what they've learned. Interestingly, bigger models are more easily tricked by conflicting information. They're also more susceptible to evidence that contradicts their existing knowledge when presented subtly, making them question what they thought they knew. The research highlights the importance of giving LLMs accurate information and the potential dangers of misinformation. The ConflictBank benchmark will be a valuable tool for researchers developing more reliable and trustworthy LLMs. It allows for deeper exploration into the complex interplay of external and internal knowledge conflicts, paving the way for LLMs that can better navigate the messy realities of conflicting information in the real world.

Question & Answers
How does ConflictBank evaluate an LLM's ability to handle conflicting information?
ConflictBank uses millions of test cases across three main categories: misinformation, temporal changes, and ambiguous meanings. The benchmark presents LLMs with contradictory information pairs and evaluates their responses based on their ability to maintain accurate knowledge despite conflicts. For example, it might present an LLM with both accurate historical data and false information about a historical event, then assess whether the model maintains the correct understanding or gets swayed by the contradictory input. This testing approach reveals that larger models, surprisingly, are more susceptible to being influenced by conflicting information, especially when it's presented subtly.
Why is it important for AI systems to handle conflicting information correctly?
AI systems need to handle conflicting information correctly because they're increasingly used in decision-making scenarios where accuracy is crucial. In everyday applications like search engines, virtual assistants, or automated customer service, AI must differentiate between accurate and inaccurate information to provide reliable responses. For example, in healthcare applications, an AI system needs to properly reconcile different medical opinions or updated treatment guidelines. The ability to handle conflicting information helps maintain trust in AI systems and ensures they remain reliable tools for businesses and consumers. This capability is especially important in an era where misinformation is prevalent.
What are the real-world implications of LLMs being susceptible to conflicting information?
The susceptibility of LLMs to conflicting information has significant real-world implications for AI deployment and usage. This vulnerability could impact various sectors like education, journalism, and business decision-making where accurate information is crucial. For instance, if an LLM-powered educational tool encounters contradictory historical facts, it might provide students with incorrect information. In business settings, this could lead to flawed analysis or recommendations based on conflicting data. Understanding these limitations helps organizations implement appropriate safeguards and verification processes when using LLM-powered systems, ensuring more reliable and trustworthy AI applications.
