false assumption
Mistaken starting belief
A false assumption is a belief taken as true without verification that turns out to be incorrect.
The phrase emphasizes that the error lies not in reasoning but in the premise itself: The whole plan was built on the false assumption that funding would continue.
False assumptions often go unexamined until their consequences reveal them.
