Boredom is an emotional state experienced during periods of lack of activities or when individuals are uninterested in the activities surrounding them.
There appear to be three general types of boredom, all of which involve problems of engagement of attention. These include times when we are prevented from engaging in something, when we are forced to engage in some unwanted activity, or when we are simply unable, for no apparent reason, to maintain engagement in any activity or spectacle.
An important psychological construct is that of boredom proneness; a tendency to experience boredom of all types. This is typically assessed by the Boredom Proneness Scale. Consistent with the definition provided above, recent research has found that boredom proneness is clearly and consistently associated with failures of attention. Boredom and boredom proneness are both theoretically and empirically linked to depression and depressive symptoms. Nonetheless, boredom proneness has been found to be as strongly correlated with attentional lapses as with depression.
Although boredom is often viewed as a trivial and mild irritant, proneness to boredom has been linked to a very diverse range of possible psychological, physical, educational, and social problems.
Boredom also plays a role in existentialist thought. In contexts where one is confined, spatially or otherwise, boredom may be met with various religious activities, not because religion would want to associate itself with tedium, but rather, partly because boredom may be taken as the essential human condition, to which God, wisdom, or morality are the ultimate answers. Boredom is in fact taken in this sense by virtually all existentialist philosophers as well as by Schopenhauer. Heidegger wrote about boredom in two texts available in English, in the 1929/30 semester lecture course The Fundamental Concepts of Metaphysics, and again in the essay What is Metaphysics? published in the same year. In the lecture, Heidegger included about 100 pages on boredom, probably the most extensive philosophical treatment ever of the subject. He focused on waiting at train stations in particular as a major context of boredom. In Kierkegaard's remark in Either/Or, that "patience cannot be depicted" visually, there is a sense that any immediate moment of life may be fundamentally tedious.
Without stimulus or focus, the individual is confronted with nothingness, the meaninglessness of existence, and experiences existential anxiety. Heidegger states this idea nicely: "Profound boredom, drifting here and there in the abysses of our existence like a muffling fog, removes all things and men and oneself along with it into a remarkable indifference. This boredom reveals being as a whole.
Arthur Schopenhauer used the existence of boredom in an attempt to prove the vanity of human existence, stating, "...for if life, in the desire for which our essence and existence consists, possessed in itself a positive value and real content, there would be no such thing as boredom: mere existence would fulfil and satisfy us.
Erich Fromm and other similar thinkers of critical theory speak of bourgeois society in terms similar to boredom, and Fromm mentions sex and the automobile as fundamental outlets of postmodern boredom.
Above and beyond taste and character, the universal case of boredom consists in any instance of waiting, as Heidegger noted, such as in line, for someone else to arrive or finish a task, or while one is travelling.
Boredom, however, may also increase as travel becomes more convenient, as the vehicle may become more like the windowless monad in Leibniz's monadology. The automobile requires fast reflexes, making its operator busy and hence, perhaps for other reasons as well, making the ride more tedious despite being over sooner.
Boredom can be a symptom of clinical depression. Boredom can be a form of learned helplessness, a phenomenon closely related to depression. Some philosophies of parenting propose that if children are raised in an environment devoid of stimuli, and are not allowed or encouraged to interact with their environment, they will fail to develop the mental capacities to do so.
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.
Boredom has been studied as being related to drug abuse among teens.
Boredom has been proposed as a cause of pathological gambling behavior. A study found results consistent with the hypothesis that pathological gamblers seek stimulation to avoid states of boredom and depression.
John Sebastian, Iggy Pop, the Deftones, Buzzcocks, and Blink-182 have all written songs with boredom mentioned in the title. Other songs about boredom and activities people turn to when bored include Green Day's song "Longview", System of a Down's "Lonely Day", and Bloodhound Gang's "Mope".
