Primates,
especially humans, are very, very good at the facial communication:
Expressing
information through facial expressions
Interpreting
information expressed facially
Distinguishing
real from fake facial information
As
with any evolutionary adaptation, there is a range of degrees. For example,
there are real, heart-felt smiles, and there are fake smiles. Donald Trump
seems to know only the latter. He thinks a smile is to make a face like he is
about to pronounce a word that begins with the letter F, or the sound SH. What
about Mike Pence? He seems to smile only with great difficulty, making it hard
to tell if his smiles are real or fake.
