You suspect a patient's elaborate account of a dramatic personal history may be pseudologia fantastica rather than confabulation or ordinary lying. Which single approach would most usefully help clarify this?
Gently presenting clear factual evidence and observing the response tests exactly the feature the phenomenon's own text describes: an eventual admission of the truth when confronted with undeniable proof, distinguishing this from a fixed delusion that would remain unshaken. Direct accusation risks damaging rapport unnecessarily, uncritical acceptance misses useful diagnostic information, and general honesty reputation doesn't test this specific pattern.
Key discriminating feature: The phenomenon's own text notes that a person with pseudologia fantastica will usually admit the truth when confronted with undeniable proof, so gently testing the account against clear factual evidence, and observing whether an eventual admission follows, is diagnostically useful.
