(Current) LLM-based ideation is biased toward what the field already finds easy to think. We formalize this bias as cognitive availability and use it to identify coherent but overlooked research directions: The Alien Space of Science. 🧵 https://arxiv.org/abs/2603.01092

What if an AI system could sketch research directions before the field converges on them?

This paper explores the “alien space” of science: coherent ideas that are unlikely to be cognitively available to today’s research community.

Scientific discovery is constrained not only by what is true, but by what is cognitively available to the researchers currently exploring a field. Many directions are coherent in light of the...
