Abduce Deduce Validate Purpose Criteria Perceptions Concepts The Intelligence Process 3 We show here that validation can fail and the process will cycle until a solution (of some sort) is found. The decision to finish depends upon a validation criteria. Such a criteria will be different depending on the kind of problem to be solved. Mathematical induction will thus explore formally every natura...
