The superfluous man (Russian: лишний человек, lishniy chelovek) is an 1840s and 1850s Russian literary concept derived from the Byronic hero.[42] It refers to an individual, perhaps talented and capable, who does not fit into social norms. In most cases, this person is born into wealth and privilege. Typical characteristics are disregard for social values, cynicism, and existential boredom; typical behaviors are gambling, drinking, smoking, sexual intrigues, and duels. He is often unempathetic and carelessly distresses others with his actions.
In Experience Without Qualities: Boredom and Modernity, Elizabeth Goodstein traces the modern discourse on boredom through literary, philosophical, and sociological texts to find that as "a discursively articulated phenomenon...boredom is at once objective and subjective, emotion and intellectualization—not just a response to the modern world but also a historically constituted strategy for coping with its discontents."[3] In both conceptions, boredom has to do fundamentally with an experience of time and problems of meaning.

Thomas Goetz, the lead researcher of the work and a professor at the University of Konstanz in Germany, says the multiple types of boredom can be loosely characterized along two dimensions. First, whether it is associated with a positive (score of 1) or negative (score of 5) emotion, and second, by degree of arousal, from calm (score of 1) to fidgety (score of 5).
In a learning environment, a common cause of boredom is lack of understanding; for instance, if one is not following or connecting to the material in a class or lecture, it will usually seem boring. However, the opposite can also be true; something that is too easily understood, simple or transparent, can also be boring. Boredom is often inversely related to learning, and in school it may be a sign that a student is not challenged enough, or too challenged. An activity that is predictable to the students is likely to bore them.[31]

The bored antihero became prominent in early 20th century existentialist works such as Franz Kafka's The Metamorphosis (1915),[43] Jean-Paul Sartre's La Nausée (1938) (French for 'Nausea'),[44] and Albert Camus' L'Étranger (1942) (French for 'The Stranger').[45] The protagonist in these works is an indecisive central character who drifts through his life and is marked by ennui, angst, and alienation.[46]
There’s no specific, medical treatment for boredom. However, there are tons of solutions if you’re experiencing boredom. For example, you may want to consider trying some new hobbies or other new diversional activities. Joining a club can be a good way to thwart your boredom. Reading clubs, hobby groups, or exercise groups are all great places to start. Joining a community group that organizes activities and outings is another good idea.
