Making selections for those bracket pools takes time away from everything else, including scholarship, according to a new study  by a Duke University professor. Charles Clotfelter, Z. Smith Reynolds Professor of Public Policy at Duke’s Sanford School of Public Policy, analyzed data on journal article viewing at 78 research libraries. He found that a drop in usage in the week after the pairings are announced for the National Collegiate Athletic Association men's basketball tournament. Further, he found additional drops at colleges and universities that won "toss-up" games, in the days following those games. “This drop in research activity in these libraries is quantitative evidence of the NCAA tournament’s power to influence patterns of work,” Clotfelter said.
