Upcoming Meetings

Saturday, September 15, 2018 - Guerrilla Skepticism on Wikipedia (GSoW)

Time: 2:00 PM
Location: Community College of Philadelphia, Room C2-28 Details
Speaker: Rob Palmer
Have you heard of the Guerrilla Skeptics? They are a dedicated team working on Wikipedia, battling conspiracy theories, alternative medicine, and pseudoscience, and improving the skeptical and scientific information in the world’s number one source of general knowledge. Though small in number, the team's work reaches tens of millions, in many languages. And their adversaries just can't stand them. In fact, GSoW has been publicly denounced by the likes of Gary Null, Rupert Sheldrake, and Deepak Chopra. In his talk, Rob will explain the importance of both Wikipedia and the GSoW project to the Skeptical movement, provide numerous examples of the work of the GSoW team, and discuss the impact that their efforts make on the general public.
Rob Palmer has been a member of GSoW since 2016 and has made over 6,100 edits to the encyclopedia in that time, doing everything from adding skeptical and science-based material to existing articles to writing brand new articles on a wide variety of topics of interest to the Skeptical movement. Rob’s Phactum article about GSoW appeared in the April 2018 edition. Since May, 2018, Rob has also been a columnist for the Skeptical Inquirer, writing under the banner "The Well-Known Skeptic." You can follow his work on Facebook at TWKSkeptic.
