Like Dr. John Mack at Harvard, Brown has aroused strong criticism from some of his university peers for delving into UFO and ET investigations. In Brown's case, the criticism is compounded because his methodology -- remote viewing -- has not been established as a reliable investigative tool by academic standards. According to assistant professor of psychology Dr. Scott O. Lilienfeld, Brown's credibility took a severe tumble when he refused to participate in a controlled experimental test of remote viewing. Yet, while concerns about Brown's work run deep, and are echoed by academic critics at other institutions, a strong adherence to the principle of academic freedom seems likely, for the moment, to protect Brown from any formal repercussions on the Emory campus.
