How did inductive divination use signs that were meant to be read by a fixed procedure?

Inductive divination relies on fixed, mechanical procedures that are intended to be objective and consistent, ideally yielding the same results regardless of the individual practitioner. This method operates on the premise that specific signs can be generated or observed through a set process, which is believed to be free from mundane or subjective control.1

These procedures often involve:

• Artificially Contrived Events: Diviners may create signs through controlled actions, such as the movement of sacrificial smoke, the casting of dice or lots (cleromancy), or the heating of bone or shell (scapulimancy).23
• Systematic Mapping: In practices like haruspicy, the liver of a sacrificial animal was mapped as a microcosm, with specific sectors assigned definite meanings, allowing the diviner to read the organ as one might read a palm.2
• Pre-existing Data: Some forms use predetermined information, such as the birth date and hour of individuals, which are analyzed according to established rules to reach a conclusion.1

By following these rigid frameworks, practitioners sought to discover divine will or future outcomes through a structured, quasi-scientific approach.21
