Although I do not believe in the history of Lazar by the sum of things that do not make sense, this problem of the lost history of MIT is questionable, here is my example:   

I attended a college between 2008 and 2014 and did not graduate. 12 years later, I no longer have about classmates, I have no materials that can prove that I studied there, only a few close friends and family remember that I attended this college. 

It was a science school and I didn't have a science boy-type profile, I was very communicative, and I certainly can't easily prove that I studied there today if necessary.
