Useful cue one: brow position. Permanently high-set brows widen the eye and read as receptive; people with them tend to signal engagement early and revise openly. Adjust your pacing accordingly.
Useful cue two: lid exposure. Hooded lids hide micro-expression. If you cannot read someone, it may be geometry rather than hostility — ask instead of guessing.
Useful cue three: mouth line at rest. A fine, firm resting line usually means fewer words per turn, not disapproval. Leave silence for them to fill.
Useful cue four: mid-face volume. Fuller cheeks correlate with higher perceived warmth, which means those people receive more social bids and are often more socially tired than they appear.
Pure superstition: forehead lines as intelligence, ear size as longevity, and any claim that a feature predicts honesty. Discard all three.
