The history of science is filled with examples of frontier ideas that were initially dismissed as speculative, ambiguous, or incredible—only to later become cornerstones of established theory and technological practice. Today, however, scientific institutions often struggle to engage productively with such frontiers. This has led to a polarization: on one side, established scientific communities tend to distance themselves from areas marked by ambiguity, speculation, stigma and claims of anomalies; on the other, fringe communities may embrace these domains but often lack the critical standards necessary for rigorous advancement.

In this talk, I propose a middle path: a framework for constructive engagement with frontier science. I argue that genuine progress in such domains requires an epistemic orientation that combines critical rigor with institutional imagination. This includes the creation of protected spaces where researchers can systematically engage with a defined set of questions. Such engagement may involve curating the most promising experimental and theoretical contributions to date, critically evaluating them and identifying shortcomings along with ways of overcoming them, upgrading diagnostics and experimental protocols, establishing best practices and standards for data transparency, and clarifying the epistemic thresholds for making specific types of claims. Crucially, this also requires an awareness that not all scientific challenges are on the cusp of resolution. Some phenomena may require decades (or more) of sustained investigation, and the mode of engagement must be selected accordingly.

I illustrate these ideas through our recent work on low-energy nuclear reactions (LENR)—a field long associated with the controversial legacy of „cold fusion.“ Our team helped move this topic across the demarcation line to become subject to systematic and rigorous investigation. I conclude by considering how the lessons from LENR may apply to other frontier domains, such as quantum biology and consciousness studies. I hope to open a broader discussion on how scientific institutions can better navigate early-stage uncertainty—when the empirical signal is weak, but the potential stakes are high.
