## Summary

A new opinion piece in Nature Machine Learning argues that while AI boosts individual researcher productivity, it is narrowing the scope of scientific inquiry. The authors note that academics using AI tools publish about three times as many papers and receive nearly five times as many citations, yet AI-assisted research covers 4.6% less topical ground than non-AI work. This pattern appears in more than 70% of subfields studied. The core issue is institutional: current incentive systems reward speed and measurable outputs, encouraging researchers to extend familiar lines of work rather than explore new, harder-to-measure areas.

The authors highlight that AI has drastically reduced the cost of generating predictions from existing data. For example, Google’s GNoME identified 381,000 candidate stable inorganic crystals, and DeepMind’s AlphaFold generated over 214 million protein structures. In contrast, building new observational infrastructure, such as longitudinal cohort studies, remains expensive and slow. The cost of making predictions with AI has fallen roughly 100-fold in the past two years, widening the gap between cheap exploitation of existing data and expensive exploration of new data sources.

To address this, the authors recommend that funders subsidize new data infrastructure, particularly in neglected domains. They also urge universities and funding agencies to stop penalizing researchers who pivot into new fields, as AI tools lower the informational cost of entering unfamiliar terrain. Without these changes, the authors warn that AI will accelerate the trend toward less disruptive, more narrowly focused scientific work.

## Key points

- AI-assisted research spans 4.6% less topical ground than non-AI work in over 70% of subfields.
- Cost of AI predictions fell 100-fold in two years, widening gap between data exploitation and creation.
- Authors urge funders to subsidize new data infrastructure and stop penalizing researchers who pivot fields.

## Why it matters

If institutional incentives remain unchanged, AI may accelerate the narrowing of scientific exploration, reducing the discovery of novel ideas and new data sources despite increased individual productivity.
