Men Show Feelings In Lower Left Quadrant Of Face: “When it comes to men, women and emotion, pet theories abound on
whether one sex is more emotional or inhibited than the other.

But since such notions are rarely backed by data, University of Florida
researchers turned to computer technology to quantify gender differences in
one component of emotional expression — how it is revealed by the face.

They discovered that although men and women are equally expressive, men
display most of their joy, disgust or other sentiments in the lower left
quadrant of their face. Women, on the other hand, show their emotions
across their entire countenance.” UniSci
