This Emotional Life

"For the INTP, emotions are seen as something mysterious and as uncontrollable as they are unalterable. Hence, the root of the fear of emotions is the fear that they cannot be controlled. Hence, when an INTP does finally respond emotionally to something, his emotions are indeed left uncontrolled, raw and open. However, when witnessing the emotional response of another person, the INTP intensely resists any similar emotion of his own. An example of this is when watching a 'weepy' cinema film in which some heart-wrenching scene is being shown. The INTP despises the attempt by the filmmaker to influence his emotions and is more likely to sneer than cry."

True. However -

"When an INTP female's feeling side does surface, it often does so with an intensity, an outpouring that can be frightening to both herself and others."
