Subject: Emotion as deception
Dear Jeffrey,
Recently, I realized that emotional expression did not evolve as a =eadout of the mental states of people, but via
adversarial deception. =s soon as people (or social animals) started to evolve the ability to =nfer the attitudes and
mental configurations of others by observing =heir posture, gaze and face, the observed ones evolved the ability to
=ame that modeling. Emotional expression is a hack on emotion =ecognition. In turn, the observers evolved the ability to
take this =nto account, and now expected that certain emotional states would be =ccompanied with default expressions,
and they'd have to look =or the subtle deviations from the defaults if they wanted to infer the =ctual mental state. The
result arms race is probably what is =esponsible for the expression archetypes.
I wonder if it is possible to simulate the adversarial evolution of =motional expression in a game theoretic setting. (I
thought you might =ike the idea that useful differentiation of communication may have =volved from deception.)
Unrelated: The Science of Consciousness Conference folks have published = short interview, this time with a better shirt:

Also, the IRS has written a letter demanding to get paid; could we =lease do something about that?
Bests,
