Watch this video with no audio. What facial expression does Zac Efron display with a very high frequency? - An expression which he uses much more often than is seen in the general population?
These images above are but three of many examples: an Elevated Central Forehead Contraction (elevated CFC) simultaneous (or nearly simultaneous) with a partial (Insincere) mouth smile.
Now, of course, we all exhibit this same expression on occasion. These include the emotional displays of:
• Disbelief (more specifically, Smug Incredulity)
We're all allowed to feel these emotions - once in a while. As long as these feelings don't occur too frequently - they are part of the normal human experience. It's also important to note that all three of these emotions may be manifested via other facial expressions.
But Sociopaths (Antisocial Personality Disorder) and bad actors (can you name any other groups?) will display this facial configuration with much greater frequency compared with the general population.
Intriguingly - if we nuance this behavior further within the acting profession - men (both straight and gay) commit this theatric faux pas much more often than women.
What should immediately strike you is the common denominator of these two groups. For sociopaths are, to a large extent, actors. They're not great actors - but most of them, for at least small segments of time, are fair-to-good actors (exceptions exist of course). And to be clear, I'm NOT saying Zac Efron is a sociopath (however, in this "Vogue 73 Questions" interview, he WAS acting - he wasn't simply being "Zac").
No one who is psychologically healthy will display this facial expression too often. Thus, if you're an actor or an acting coach - eliminate it. And, for everyone else - be on guard.
Summary: When it's displayed frequently (not just within a single conversation) - an elevated central forehead contraction together with a simultaneous/nearly simultaneous mouth smile (usually just a partial smile, and by definition an insincere, mouth smile) - has a very high correlation with antisocial personality disorder (sociopathic behavior). Take heed.
