Brendan Case

Position and Background

Brendan Case is Associate Director for Research at Harvard University's Human Flourishing Program, where he works at the intersection of philosophy, science, and emerging research on anomalous phenomena. He represents a new generation of academic researchers willing to challenge conventional assumptions about UAP origins without abandoning rigorous epistemic standards.

The Cryptoterrestrial Hypothesis

In October 2024, Case co-authored a landmark peer-reviewed paper titled "The Cryptoterrestrial Hypothesis: A Case for Scientific Openness to a Concealed Earthly Explanation for Unidentified Anomalous Phenomena" with Tim Lomas (Harvard University) and Michael P. Masters (Montana Technological University). The paper was published in Philosophy and Cosmology, a scholarly journal indexed in major academic databases.

The cryptoterrestrial hypothesis proposes that certain UAP may reflect activities of intelligent beings concealed in stealth on Earth itself—whether underground (e.g., subterranean civilizations), in near-Earth environs (e.g., the moon, near-Earth asteroids), or even hidden within human populations. This represents a middle-ground position: neither the conventional explanation (human-made technology) nor the extraterrestrial hypothesis (advanced alien visitors), but rather an "unconventional terrestrial" or "ultraterrestrial" explanation.

Epistemic Humility and Scientific Openness

Case and his co-authors characterize their work explicitly as "speculative" and acknowledge believing the cryptoterrestrial hypothesis "in all likelihood false." Yet they argue passionately that scientific discourse demands genuine openness to such possibilities rather than dismissal. Their central claim is that UAP evidence—including eyewitness accounts from credible observers, radar-visual correlations, and physical traces—warrants examining the cryptoterrestrial hypothesis seriously within mainstream scientific frameworks.

The paper frames three classes of UAP hypotheses: (1) conventional terrestrial (human technology), (2) extraterrestrial (advanced civilizations from space), and (3) unconventional terrestrial/ultraterrestrial (hidden earthly intelligence). Case argues that epistemic humility—recognition of how much we don't know about Earth's past, geology, and potential hidden ecosystems—demands that science remain open to the third category without prejudgment.

Academic Impact and Reception

The cryptoterrestrial hypothesis has gained traction in both academic and public discourse since its publication, with secondary discussions appearing in Medium, educational platforms, and UAP research communities. Case's work exemplifies the broader shift toward academic legitimacy for UAP studies in the disclosure era, where scholars from elite institutions increasingly contribute to the discourse. His affiliation with Harvard's Human Flourishing Program—an institution dedicated to rigorous interdisciplinary research on human wellbeing—lends credibility to the cryptoterrestrial framework as a serious intellectual proposition rather than fringe speculation.
