Extraordinary Claims and Unequal Skepticism |
Carl Sagan famously observed that “extraordinary claims require extraordinary evidence.” That principle is especially important when accusations are both highly sensational and politically explosive.
History repeatedly shows what can happen when emotionally overwhelming allegations outrun careful evidentiary scrutiny. The past half-century has seen multiple episodes in which extraordinary claims generated moral panic long before evidence justified certainty. During the Satanic Ritual Abuse panic of the 1980s and 1990s, daycare workers and others were accused of belonging to secret abuse cults that allegedly engaged in elaborate rituals, torture, hidden underground chambers, and organized sexual abuse of children. In cases such as the McMartin preschool prosecution, emotionally charged testimony and media amplification created overwhelming public certainty despite the absence of meaningful physical evidence. Innocent people spent years under prosecution, some serving prison time, before many of the allegations ultimately collapsed under scrutiny or were found to be unsupported.
Nor is this dynamic limited to one political or cultural setting. Modern history has repeatedly shown how emotionally powerful testimony, social reinforcement, ideological expectation, and media amplification can lead large numbers of otherwise intelligent people to accept extraordinary claims........
