Origins & the Lab-Leak Question

The confidence gap

Read the investigation →
The Proximal Origin confidence gap, January–April 2020 A timeline plotting stated confidence in a natural origin for SARS-CoV-2. Private statements stay low to uncertain through mid-February; public statements jump to high certainty by mid-March, then again in April. HIGH — “a natural origin” LOW — “could be engineered” THE GAP Jan 31 “could look engineered” Feb 8 “isn’t conclusive enough” Feb 12 “a serious scientific theory” Mar 17 “not plausible” Apr 17 cited from the podium
Private — emails & testimony Public — the paper & the podium The vertical axis is the authors’ and officials’ stated confidence in a natural origin. Private correspondence held at “isn’t conclusive enough” into mid-February; the published paper declared a lab scenario “not plausible” five weeks later. Each point is sourced in the investigation.
