Advancing the Scientific Method with Large Language Models: From Hypothesis to Discovery

TL;DR

Large Language Models are transforming scientific research by assisting in hypothesis generation, experimental design, and data analysis, but challenges like hallucinations and ethical concerns must be addressed for effective integration.

Contribution

This paper reviews how LLMs are redefining the scientific method and discusses their potential applications and challenges across the entire scientific cycle.

Findings

LLMs are increasingly involved in experimental design and data analysis.

Challenges such as hallucinations and reliability issues persist.

Deep integration of LLMs into scientific workflows can enhance productivity and discovery.

Abstract

With recent Nobel Prizes recognising AI contributions to science, Large Language Models (LLMs) are transforming scientific research by enhancing productivity and reshaping the scientific method. LLMs are now involved in experimental design, data analysis, and workflows, particularly in chemistry and biology. However, challenges such as hallucinations and reliability persist. In this contribution, we review how Large Language Models (LLMs) are redefining the scientific method and explore their potential applications across different stages of the scientific cycle, from hypothesis testing to discovery. We conclude that, for LLMs to serve as relevant and effective creative engines and productivity enhancers, their deep integration into all steps of the scientific process should be pursued in collaboration and alignment with human scientific goals, with clear evaluation metrics. The transition to AI-driven science raises ethical questions about creativity, oversight, and responsibility. With careful guidance, LLMs could evolve into creative engines, driving transformative breakthroughs across scientific disciplines responsibly and effectively. However, the scientific community must also decide how much it leaves to LLMs to drive science, even when associations with 'reasoning', mostly currently undeserved, are made in exchange for the potential to explore hypothesis and solution regions that might otherwise remain unexplored by human exploration alone.
