Inside Higher Ed has a great piece on an April Fool's joke pulled by a faculty member at Brown on his colleagues in the math department. He sent out an email letting folks know about a new admissions policy that the university would use, since the standard admissions criteria were not successfully predicting students' academic performance. They would admit 20% of students using a random selection process. As he quoted one administrator, “In the absence of any other good criterion, it seems fair to give the benevolent hand of chance a greater role in guiding the future of higher education.”
While he included a link that led to a website that said, "Happy April Fools Day," several of them failed to click on the link, relied solely on the note, and took it seriously. They of course began a conversation where they expressed their concerns, raised questions about the technicalities of it, and discussed whether the 20% threshold was appropriate.
I love this kind of prank. I wish I had pulled it myself. Ah, I will just have to live vicariously... until next year!
