The Skeptics Society and Skeptic magazine investigate claims by scientists, pseudoscientists, and pseudohistorians on a wide variety of theories and conjectures including but not limited to: evolution and creationism; cults and religion; Holocaust revisionism and extreme Afrocentrism; conspiracy theories; near-death and out-of-body experiences; cryonics, life after death and the quest for immortality; witchcraft and witch crazes; mass hysterias and urban myths; the relationship of science and science fiction; hypnosis and altered states of consciousness; the difference between science and pseudoscience and the difference between history and pseudo history; magic and the paranormal; the use and abuse of theory and statistics in science and pseudoscience; the role of skepticism; medical and psychiatric claims; the scope and limitations of science and technology; gender and race issues in science, society, and history; cultural influences on science and scientific influences on culture; the capacities and limitations of the human mind and body; scientific and academic fraud and hoaxes. The question the Skeptics Society asks about all claims it investigates is this: How well do they hold up under scientific scrutiny?
With regard to statements, hypotheses, theories, and ideologies considered by the Skeptics Society, the organization adopts the posture of the 17th-century Dutch philosopher Baruch Spinoza:
"I have made a ceaseless effort not to ridicule, not to bewail, not to scorn human actions, but to understand them."
With regard to its procedure of examination of all claims, the Skeptics Society adapts the scientific method developed in the 16th and 17th centuries. It recognizes the limitations and socio-cultural influences on science, yet adopts the philosophy of Albert Einstein:
"All our science, measured against reality, is primitive and childlike--and yet it is the most precious thing we have."
