When the central forehead is contracted (CFC) without a smile - it's a very strong indicator of emotional or physical pain - either experienced directly, or felt secondarily via empathy. In such body language the mouth is configured in either a pain, fear or sadness expression. Occasionally, and often briefly, the mouth may have a neutral nonverbal expression.
However, when the central forehead is contracted with even a subtle or partial "smile" (thus really a pseudosmile), not only is the smile NEVER a sincere one, but at the very best this signals arrogant-incredulity. We all occasionally display this expression of a false smile with a CFC, however interestingly, this is either rare displayed (for the vast majority of people) or displayed very often (less than 5% of the population). When an individual displays this nonverbal cluster frequently, there is a very strong correlation for narcissistic personality disorder, sociopathic behavior or psychopathic behavior.
Mr. Ronaiah Tuiasosopo, displays the body language-facial expression of a central forehead contraction with a false smile during the 0:05 - 0:06 segment, just after Dr. Phil McGraw asks him, "Were you in love with him?" (Manti Te'o). Of course, this interview is a small sample size in the life of this admitted "catfishing" perpetrator, so the frequency of this very important red flag nonverbal cannot be established here. However, it is not at all an expression one would expect to see if he were truly sorry and remorseful for his actions. Its presence thus indicates the presence of emotional dissonance.
