“My son Aaron, who is a professor of computer science, encountered just such a careless signal when he was on the admissions committee at Carnegie Mellon University. One Ph.D. applicant submitted a passionate letter about why he wanted to study at CMU, writing that he regarded CMU as the best computer science department in the world, that the CMU faculty was best equipped to help him pursue his research interests, and so on. But the final sentence of the letter gave the game away: I will certainly attend CMU if adCMUted. It was proof that the applicant had merely taken the application letter he had written to MIT and done a search-and-replace with “CMU” . . . and hadn’t even taken the time to reread it! Had he done so, he would have noticed that every occurrence of those three letters had been replaced.”
