Only in the last decade has there been much scientific research looking into the nature of boredom. In 2006, a study classified boredom into four different types, with a follow-up study published this month in the journal Motivation and Emotion adding a fifth kind of boredom, called apathetic boredom, to the list. The researchers involved in the study had 63 university students and 80 high school students answer smartphone-based surveys about their activities and experiences over the course of two weeks.
A "banishment room" (also known as a "chasing-out-room" and a "boredom room") is a modern employee exit management strategy whereby employees are transferred to a department where they are assigned meaningless work until they become disheartened enough to quit.[37][38][39] Since the resignation is voluntary, the employee would not be eligible for certain benefits. The legality and ethics of the practice is questionable and may be construed as constructive dismissal by the courts in some regions.

"Meh" is an interjection used as an expression of indifference or boredom. It may also mean "be it as it may".[40] It is often regarded as a verbal shrug of the shoulders. The use of the term "meh" shows that the speaker is apathetic, uninterested, or indifferent to the question or subject at hand. It is occasionally used as an adjective, meaning something is mediocre or unremarkable.[41]
