In socionics black ethics (Fe) is called "the ethics of emotions." It is easiest to determine whether Fe is a strong function in person if you watch how he shows his emotions. However, emotion and Fe are different. All people have emotions (at the same time Fe may not be in someone's Ego). Also, normally, term 'emotional person' is commonly referred to sensitive people, and this fact has NOTHING to do with Fe. In socionics "sensitivity" is rather intuitive characterization. Fe in the structure of sociotype essentially is responsible for making unified and understandable (emotional) evaluations without words. If Fi is responsible for setting their own personal, individual, special relationship to the different objects of the world, Fe forms the general attitude of everything obvious.

Such judgments (or evaluation) of situation as "Class!", "Super!", "Sucks!", "Horror!" and the likes, are essentially Fe (these phrase don't have any meaning really, but we immediately understand the assessment of what is happening).Mobility of the emotional life is the distinguishing feature of Fe. Fe person very easily makes emotional judgments and is not shy about stating them. Fe is a public function: acting, ability to attract the audience's attention and hold it, the ability to impose a lot of emotions, inspire, generate passions and moods - all that is a lot easier for a Fe person than any other sociotype. and so on...
