FALSIFYBENCH: Evaluating Inductive Reasoning in LLMs with Rule Discovery Games

arXiv:2606.04751v1 Announce Type: new Abstract: Large language models (LLMs) are increasingly deployed as autonomous agents in scientific tasks. Yet whether these systems can effectively engage in forms of inductive reasoning relevant to scientific discovery remains an open question. In this work, we introduce FALSIFYBENCH, an evaluation framework for hypothesis-driven reasoning inspired by the classic Wason 2-4-6 task, in which agents must discover hidden semantic properties by iteratively proposing examples and receiving feedback. This task captures key elements of scientific reasoning: hypo

Why this matters
Why now

The increasing deployment of LLMs as autonomous agents necessitates robust evaluation frameworks to understand their scientific reasoning capabilities beyond mere task completion.

Why it’s important

This development is crucial for determining if LLMs can genuinely contribute to scientific discovery and complex problem-solving, rather than just data processing or pattern recognition.

What changes

The introduction of FALSIFYBENCH provides a standardized method to assess inductive reasoning in LLMs, which was previously difficult to quantify effectively.
