The Skeptic's Toolbox is an annual four-day workshop devoted to scientific skepticism. It was formed by psychologist and now-retired University of Oregon professor Ray Hyman, has been held every August since 1992, and is sponsored by the Committee for Skeptical Inquiry. The workshop focuses on educating people to be better critical thinkers, and involves a central theme. The attendees are broken up into groups and given tasks that they must work on together and whose results they must present in front of the entire group on the last day.
