Final answer:
When conclusions are based on established authority rather than empirical evidence, the term pseudoscience is applicable; unlike science, pseudoscience lacks empirical testing and validation.
Step-by-step explanation:
Something that bases conclusions on established authority rather than empirical evidence is considered pseudoscience. In contrast, science relies on the scientific method, which includes observation, hypothesis development, experimentation, and revision based on empirical data. Pseudoscience, however, may invoke the authority or the appearance of science but lacks the rigorous methodology and is not supported by credible scientific research. Claims from pseudoscience cannot be easily tested or falsified, which is a key characteristic that separates it from science.
