These authors suggest that attention plays an important role in creating boredom. In particular, there are a few conditions that need to be met for people to feel bored. First, people need to have a reasonable level of psychological energy or arousal to feel bored. When people have low arousal and there is not much happening in the world, then they often feel relaxed. When they have high arousal, though, they have energy they would like to devote to something, but they cannot find anything engaging.
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 is a universal experience. Almost everyone suffers from it in the course of their lives. Existing survey estimates show that between 30 percent and 90 percent of American adults experience boredom at some point in their daily lives, as do 91 percent to 98 percent of youth (Chin et al., 2017). Men are generally more bored than women. There is also a positive link between very low educational attainment and boredom.
Grunge lit is an Australian literary genre of fictional or semi-autobiographical writing in the early 1990s about young adults living in an "inner cit[y]" "...world of disintegrating futures where the only relief from...boredom was through a nihilistic pursuit of sex, violence, drugs and alcohol". Often the central characters are disfranchised, lacking drive and determination beyond the desire to satisfy their basic needs. It was typically written by "new, young authors" who examined "gritty, dirty, real existences" of everyday characters. It has been described as both a sub-set of dirty realism and an offshoot of Generation X literature. Stuart Glover states that the term "grunge lit" takes the term "grunge" from the "late 80s and early 90s—...Seattle [grunge] bands". Glover states that the term "grunge lit" was mainly a marketing term used by publishing companies; he states that most of the authors who have been categorized as "grunge lit" writers reject the label.
