Swanson’s software, Arrowsmith, identified indirect connections within published papers, successfully proposing hypotheses from vast datasets, like the potential of fish oil to treat Raynaud’s syndrome. Today, AI systems, armed with advanced natural language processing capabilities, construct ‘knowledge graphs’ and identify potential links between various elements, propelling advancements in drug discovery, gene function assignment, and more.

In October 2023, amidst the announcement of the Nobel laureates, a group of researchers, including a previous laureate, met in Stockholm to discuss the expanding role of artificial intelligence (AI) in scientific processes. Led by Hiroaki Kitano, the chief executive of Sony AI and a prominent biologist, the discussions unfolded around the potential creative contributions of AI in scientific endeavors. Notably, Kitano had previously proposed the Nobel Turing Challenge, envisioning highly autonomous AI systems, or ‘AI scientists,’ capable of Nobel-worthy discoveries by 2050.

Synthetic Data and AI Hallucinations: Catalysts for potential medical breakthroughs?

AI’s potential in medicine unfolds through its ability to assist scientists in brainstorming. The unique ability of AI to generate hypotheses based on synthesized data, often likened to ‘hallucinations,’ has the potential to revolutionize the traditional boundaries of medical inquiry.

A review on synthetic data in healthcare explores the role of synthetic data in health care, addressing the controlled access limitations to real data. It identifies seven use cases, including simulation, hypothesis testing, and health IT development. While emphasizing the preference for real data, the review highlights synthetic data’s potential in overcoming access gaps, fostering research, and informing evidence-based policymaking, citing various accessible datasets with varying utility.

1. Unleashing the Creative Spark

Large language models, shaped by extensive exposure to diverse textual data, exhibit a distinctive capability – they can ‘hallucinate’ or generate hypotheses. AI’s ‘hallucinations’ should not be misconstrued as mere whimsical outputs. This process, akin to a creative spark, allows AI to propose potential truths or connections that might elude human researchers.

By presenting hypotheses that appear plausible within the vast landscape of medical knowledge, AI aids researchers in identifying promising leads, prompting further investigation into uncharted territories.

2. Emphasis on ‘Alien’ Hypotheses

Sociologist James Evans, a proponent of AI’s potential in drug discovery and other medical breakthroughs, underscores the significance of AI in producing ‘alien’ hypotheses — ideas that human researchers might be unlikely to conceive. The essence lies in AI’s capacity to explore unconventional paths, connecting disparate elements within vast datasets that may not be immediately evident to human researchers.

3. Beyond Human Cognitive Constraints

The human mind, while immensely powerful, operates within certain cognitive constraints. AI, free from these limitations, explores avenues that might seem alien or unconventional to human thinkers. This escape from the expected norms becomes a catalyst for disruptive thinking, potentially leading to novel approaches, treatments, or diagnostic methods in the medical domain.

4. Enhancing Research Agility

In a field where adaptability and agility are paramount, AI’s contribution to medical research lies in its ability to suggest hypotheses that might align with emerging trends, recent findings, or unconventional patterns. This accelerates the pace of discovery, enabling researchers to navigate complex medical landscapes with greater efficiency.
