why do we get bored, and what is the point of boredom? The science of being sick and tired

WheelSo, what is exactly is boredom?

The Oxford dictionary describes it as: “Feeling weary and impatient because one is unoccupied or lacks interest in one’s current activity”. For a feeling so common, it's surprising that the word first appeared written down in 1852, in Charles Dickens’ Bleak House. In it, Lady Dedlock says she is “bored to death” with her marriage. The late Robert Plutchik, a Professor Emeritus at the Albert Einstein College of Medicine, created a “Wheel of Emotions” (extended in order of intensity) in 1980, and placed boredom after disgust, as a milder form of disgust:

Although boredom is essential for human development it’s been given a bad rap. “Boredom has traditionally been associated with a range of negative outcomes, both within the workplace and outside it,” Sandi Mann and Rebekah Cadman of the University of Central Lancashire write in their 2014 paper. Mann and Cadman examined the relationship between boredom and creative potential on a range of tasks in two studies. In the first study, 80 eager volunteers visited their lab only to be given the dull, monotonous chore of copying out lengthy lists of telephone numbers, or to be excluded from it (this was the control group), followed by the creative task of thinking of as many possible uses for a pair of plastic cups. In the second study, a further 90 volunteers were split into three groups, each group being assigned to various types of boring activities (copying numbers, reading the numbers, or being excused from the whole thing – again, a control), followed by a creative task. “Results suggested that boring activities resulted in increased creativity and that boring reading activities lead to more creativity in some circumstances,” the authors write.
