Because like you well indirectly stated, it is a matter of opinion. I base mine on many years dealing with different characters from different medical schools, and I have seen my fair share of everything. From those who consider basic sciences as a prep course for the USMLE(Both from the U.S. as wel as Caribbean schools) to those who consider basic sciences sacred religion. I have seen excellent basic sciences students who don't have a clue as to how medicine works until their clinical years, some in residency. (Both U.S. and Caribbean) and I have seen those who have mastered this science from day one.
Unfortunately the medical boards won't license people from KAPLAN studies. I agree though, that many exceptionally brilliant people who have never seen a medical school can take and pass the USMLE with a KAPLAN REFRESHER COURSE. and that is precisely my point concerning distance education and BASIC SCIENCES.
I do believe, however that eventually many,NOT ALL, U.S. Schools will do their basic sciences online, or independently like O.S.U. with some sort of supervision. My point is, that by the day they attempt this, it has already been done in Australia and the Caribbean. That the IUHS Model may be a failure or not, let time be the judge of that, not us. At least it has not been a failure at Ohio State or Sydney.
In my case, as long as the guy stiching me passed his clinicals and residency at a good hospital and passed his boards and is respected among his peers, I can care less were he learned basic sciences.
WE are all speculating here as to how the future will turn out. Some of us are more optimistic than others. This has been a great exercise.
Lets remember, the future is just once second ahead of us, and the past is one second behind.
I am leaving now for my 32 hour shift.
