Question

Quizplus · Accepted Answer

The warning sign of pseudoscience that is described in the question is the lack of self-correction. This refers to the failure of proponents of a pseudoscientific practice to modify their beliefs even in the face of clear and unequivocal evidence that contradicts their claims. In the case of speed-reading courses and facilitated communication, for example, proponents of these practices continue to promote them even though there is no scientific evidence to support their effectiveness, and in fact, much evidence to suggest that they are not effective. By ignoring or dismissing this evidence, these proponents demonstrate a lack of self-correction and a willingness to cling to their beliefs despite contradictory evidence.
