The principle. A handful of common body-language mistakes do most of the damage. Eliminating them lifts close rate before any script change.
The top 8 mistakes.
- Looking away when stating price. Reads as you don't believe in it.
- Crossed arms. Even if you're cold — buyers read it as defensive.
- Tapping or fidgeting — pen, leg, fingers. Anxiety leak.
- Filling silence with movement. Pacing, swaying, head bobbing.
- Over-nodding. Eager-to-please tell.
- Frozen smile during objections. Reads as scripted.
- Touching the face/neck under pressure. Self-soothing tell.
- Standing over a seated buyer in-home — power imbalance.
The fix for all of them. A 10-second pre-call body reset: feet planted, shoulders down, jaw unclenched, soft smile baseline, hands visible. The reset interrupts the nervous-system loop that creates these tells.
Key takeaway. Don't try to add confident body language. Subtract the tells first. The confidence is already there — the tells are masking it.
