Faces and vibes mislead you more than they guide you in judging truth

Many of us trust expressions and tone as windows into truth. Yet studies find our accuracy hovers just above chance when we judge lies in short clips. In courtrooms and meeting rooms, confident demeanor and smooth delivery are often mistaken for honesty, while nervousness gets misread as deception. That mismatch hurts both fairness and performance. It also explains why seasoned professionals can still be fooled by people who look and sound “right.”

Consider a hiring panel swayed by a polished answer, even as the candidate dodges specifics. The panel’s notes gush about confidence and culture fit. Weeks later, the same panel wonders why deadlines slip. The problem wasn’t malice. It was over‑weighting demeanor and under‑weighting verifiable behaviors. A checklist forces attention back to data that predicts outcomes.

A small experiment helps. Turn off cameras for the first interview. Rate only on predefined behaviors: evidence of prior results, clarity of process, and teach‑back ability. Notice how different your notes feel. The coffee on your desk might go cold as you reread tighter answers. You may still bring video back later for rapport, but the first pass stays clean of appearance bias.

The broader principle is simple. If faces and vibes add noise, blunt them early. If base rates carry quiet wisdom, bring them forward. You’re not removing humanity, you’re sequencing it. Let structure speak first, then feelings. The blend is kinder and more accurate than the vibe alone.

For your next evaluation, hide photos and turn off video for the first round, then rate candidates against a short checklist tied to outcomes, like evidence of past results or clarity of process. Look up a relevant base rate that applies in your context and compare your ratings to it before you let your gut weigh in, and then schedule a ten‑minute pause before you decide. When you return, skim your scores, not your first impressions, and only then add any human notes. Try this sequence once and compare results to your usual method.
