Why does Harvard defer so many applicants?

@ibanker38 Actually, what JHS said supports my description, or it’s not as clear as I would like.

“That would mean that Harvard probably accepted a slightly lower percentage of RD applicants than Stanford, because more of the people it was accepting RD were deferred SCEA applicants. But Harvard generally doesn’t want to publicize that, and goes to some lengths to make it difficult to figure out.”

It would be helpful if @JHS could clarify if he is inclined to do so. I am just curious to find out how this college admission game works.
