From that fundamental misunderstanding of science as a position, not a method, Bloom and Weisberg go on to enumerate their prejudices:
Many believe in the efficacy of unproven medical interventions, the mystical nature of out-of-body experiences, the existence of supernatural entities such as ghosts and fairies, and the legitimacy of astrology, ESP, and divination.
Bloom and Weisberg sneer at these beliefs as "unscientific". But of course what is unscientific is to make a dogmatic judgement for or against the reality of a phenomenon without evidence. Actually, most of their "roll of anti-scientific errors" are in fact supported by scientific research and anecdotal evidence of the highest quality. These two authors seem to feel that all belief systems should be discounted, except their own, which cannot be questioned or examined scientifically because it is a priori true.
The question must be asked, why do people like Bloom and Weisberg resist the scientific inquiry of their materialistic belief system?
