See the New York Times story [here](http://economix.blogs.nytimes.com/2011/02/24/princeton-and-harvard-reinstate-early-admissions/?hp).
The original policy was announced with much fanfare, but Princeton’s falling yield rate in recent years no doubt encouraged this move. Stanford never followed in the steps of these schools, and it is interesting to note that Stanford’s yield rate has been steadily increasing over the same time period.
The question is, do early programs “advantage the advantaged” as Princeton’s original press release argues, or are there methods to ensure that early action/decision programs are diverse and well-balanced?
