Common questions
How should a report handle a finding with evidential ambiguity?+
By presenting the competing explanations and, where possible, an estimate of their relative likelihood, rather than selecting one interpretation and presenting it as certain. This lets the trier of fact weigh the evidence properly.
Does evidential ambiguity mean the evidence is worthless?+
No. Ambiguous evidence can still narrow the range of possibilities or corroborate other findings, even if it cannot support a single definitive conclusion on its own.
