The Declared Anchor Errors, by Unit
Captions available
The idea
Where an anchor contradicted itself, the course resolved it on its own text or a primary source: TARP and the Populists in 02; Brooks's dates in 03, 04; Hidalgo in 06; three-fifths in 07; proven reserves in 12; national income and marginal rate in 14; trade balance in 15.
In practice
Each fix names its source.
Where people slip
A textbook's slip is not the learner's.
