Executive Summary

Layman observers’ theories in recent years about missing and deceased U.S. scientists representing a coordinated effort by an unknown bad actor are unsupported by the facts of the individual cases.* Nonetheless, the speculative narratives have spread from fringe online spaces into the wider public discourse, gained the attention of some U.S. politicians, and led to a tax-payer funded federal-level investigation. 

The grouping largely includes individuals in unrelated fields and with varying access and clearance levels, inconsistent with a coordinated targeting profile. The individual cases’ documented circumstances offer more feasible explanations than the claim of coordinated targeting, calling for an application of Occam’s Razor. Furthermore, at system scale, the observed number of cases is not statistically anomalous when considered against the size of relevant populations. The conspiracy narrative is largely driven by base rate neglect and relies on artificial and misrepresented claims.

*Background: The list of dead and disappeared scientists, drawn from cases over roughly four years, now includes at least 14 individuals. The cases have fuelled speculation about conspiracies ranging from UFO related programmes to attacks by foreign adversaries or even the U.S. state itself. Skeptics have long engaged with public conjecture about missing or deceased individuals linked to sensitive or high-level roles, but this narrative has recently scaled attention, drawing congressional interest and questions from President Donald Trump.
