The answer: Probably both.
I think most people question the sincerity of the series show “The Bachelor” and “The Bachelorette” (even though many of us may still watch it anyways!) Remember the theme song for his season “On the Wings of Love?”
Aside from the lack of sincerity and phoniness present in series, Jake appears to demonstrate a serious lack of genuineness and authenticity. His facial expressions are incongruent with the content of his speech. For example, he smiles when he is angry. He uses an upbeat happy tone of voice when really he is distraught and unhappy. Jake appears to be hiding his true intentions. He may be consciously deceitful to others in order to get what he is seeking. He may also be out of touch with his true self and have a lack of awareness of who he really is inside- which leads to a lack of sincerity in his interactions with others.
If you know someone who demonstrates a serious lack of sincerity, be careful. Be especially cautious in entering into a relationship with someone if they show other signs of deceit, lack of empathy and poor judgment this may be a sign of a very serious and destructive personality type.
