Analytical Questions
What does the available evidence indicate about the origin of SARS-CoV-2?
The probability in parentheses is how likely each explanation is on its own; it does not compare explanations to each other.

Research-related origin
(unlikely)
Best case for Research-related origin
- DARPA grant proposal 'DEFUSE' submitted by EcoHealth Alliance in 2018 included plans to introduce furin cleavage sites into bat coronaviruses in collaboration with Wuhan Institute of Virology.
- Declassified documents released on June 20, 2026 reveal collaboration between Anthony Fauci and intelligence community leaders to influence intelligence agency assessments regarding COVID-19 origins.
- Lawrence Tabak, Deputy Director of National Institutes of Health, described to Congress in October 2021 a limited gain-of-function experiment in which researchers used WIV1 bat coronavirus with spike proteins replaced and infected genetically modified mice, with some mice becoming more severely ill than with unmodified virus.
Not resolvable on the available evidence
(unlikely)
