| The Physical Trait | The NT Misinterpretation | The ND Biological Reality |
| Fixed Gaze (“Dark Eyes”) | Hostility, anger, or “psychopathic” lack of empathy. | Amygdala Overload: Deep focus requires visual stability. Moving the eyes breaks the “flow state.” |
| Furrowed Brow | Confusion or disapproval of the speaker. | Muscular Effort: Physical manifestation of the “heavy lifting” happening in the prefrontal cortex. |
| Head Tilt | Skepticism or “looking down” on someone. | Peripheral Processing: Many ND individuals process auditory info better when not forced into direct eye contact. |
