Scientific skepticism has a long history—roughly 40 years in its most modern organized form, and centuries (arguably millennia) as a more or less recognizable tradition. (See my “Why Is There a Skeptical Movement?” for a discussion of this lengthy intellectual thread—PDF.)
We’ve learned a lot in that time. Generations of skeptics have devoted themselves to understanding paranormal and pseudoscientific claims, beliefs, and impostures. But even with those efforts, the fringe has remained radically under-examinded. Because this realm is so vast while the scholars and activists interested in exploring it are so few, our work has often had something of a scrambling quality. In our rush, skeptics have tended to neglect, or at least to set aside for some future time, some of the improvements of better-established fields.
