Evasion Versus Genuine Uncertainty
Launch library · evergreen read

A vague answer can mean two very different things: a subject who genuinely does not remember or does not know, or a subject who knows perfectly well and is choosing not to say. Telling these apart matters enormously, and conflating them leads an interviewer toward the wrong follow up entirely.
Tone offers some guidance, though never certainty. Genuine uncertainty often comes with visible effort: a pause that looks like searching, a qualified answer offered tentatively. Evasion more often arrives smoothly, sometimes with a quick change of subject, as though the answer has been prepared in advance for exactly this question.
When the distinction is unclear, a direct and respectful question can help more than further guessing: simply asking whether the subject recalls the detail, or would rather not discuss it, invites them to clarify their own position rather than leaving the interviewer to assume one on their behalf. Even a brief, respectful check can resolve the ambiguity faster than continued guessing ever would.
