Common questions

Why must a working hypothesis be falsifiable rather than just plausible?+

A falsifiable hypothesis can be tested against evidence and disproven if wrong, which keeps the investigation objective; a vague or unfalsifiable hypothesis risks the examiner selectively gathering evidence that seems to confirm a preconceived conclusion.

What happens if fieldwork contradicts the working hypothesis?+

The examiner revises or replaces the hypothesis based on the new evidence rather than discarding the contradicting findings, since the hypothesis is a working tool meant to guide fieldwork, not a fixed conclusion set before the investigation begins.
