Change Details: A previous version of this article erroneously stated that one of Ryan Raver’s thesis-committee members was reluctant to sign off on Raver’s PhD. In fact, the comment about how Raver spent his leisure time was made long after signing off on the doctorate. The text has been corrected accordingly.
