Onychomancy or onymancy is an ancient form of divination using fingernails as a "crystal ball" or "scrying mirror" and is considered a subdivision of palmistry. As with palmistry, the contradictions between different interpretations and the lack of evidence for the predictions have led onychomancy to be viewed as a pseudoscience by academics.

Physiognomy or face reading is the practice of assessing a person's character or personality from their outer appearance—especially the face. The term can also refer to the general appearance of a person, object, or terrain without reference to its implied characteristics—as in the physiognomy of an individual plant or of a plant community.
