Centennial

Martin Gardner was born one hundred years ago, on October 21, 1914. To commemorate the centennial of the birth of one of the greatest figures in modern scientific skepticism, the SKEPTICAL INQUIRER plans to republish several of his classic SI “Notes of a Psi- Watcher” columns over the next several issues. We later changed the column’s title to “Notes of a Fringe-Watcher.” We begin with his very first column, from our Summer 1983 issue. “Lessons of a Landmark PK Hoax” was “a few general comments” on ’s elaborate Project Alpha, which Randi described in an article in the same issue. Randi had arranged for two young conjurors to visit the McDonnell Laboratory for Psychical Research at Washington University, St. Louis. During two years of experiments with them, the head of the lab, physicist Peter Phillips, became convinced that the two teenaged magicians, Steven Shaw and Mark Edwards, could bend metal objects, cause light streaks on film, turn a motor under a glass dome, make fuses blow, and perform other similar wonders all with the power of their minds. Randi’s intention was to demonstrate that -minded scientists would resist accepting expert conjuring assistance in designing proper controls and therefore be easily fooled by magic tricks. When revealed as a hoax, the revelations garnered worldwide media coverage and greatly embarrassed the lab. It closed in 1985. In 1986, Randi was given a MacArthur Foundation award to continue his work in debunking fraudulent claims. Here is Gardner’s column.
