The lack of callbacks can be for all sorts of reasons, but I'd speculate that a lot of the employers simply tried to do a really quick validation check (name, school affiliation, etc.) that may even be automated and upon realizing that the individual is made up didn't call back. I think that this experiment indirectly showed how ineffective "cold-calling" via resume-dropping really is for even highly qualified individuals (although they'd have to do it with other industries perhaps for better validity, for example). Meanwhile, I'm sure callback rates are probably higher for industries with no shortage of demand for highly qualified individuals such as software engineering. Law and medicine are a bit overwhelmed with more students than there are jobs for them last I heard.
