The 3900 number is mostly spread by a single researcher at Harvard who is quoted and self-quoted and cited by his own students somehow making his shoddy research some kind of "fact". Anyone trying to question this basically gets shunned from any conference this gentleman will be involved in and labelled as "revisionist".
It is incredible that Wikipedia too just quotes this single individual on hundreds of pages somehow giving him and his claims credibility. His claims have been refuted by many using plethora of evidence but his citation cartel will simply dismiss it by attacking the authors instead of their research.
