What exactly is boredom? It is a deeply unpleasant state of unmet arousal: we are aroused rather than despondent, but, for one or more reasons, our arousal cannot be met or directed. These reasons can be internal – often a lack of imagination, motivation or concentration – or external, such as an absence of environmental stimuli or opportunities. We want to do something engaging, but find ourselves unable to do so and, more than that, are frustrated by the rising awareness of this inability.
Awareness, or consciousness, is key, and might explain why animals, if they do get bored, generally have higher thresholds for boredom. In the words of the British writer Colin Wilson: ‘most animals dislike boredom, but man is tormented by it’. In both man and animal, boredom is induced or exacerbated by a lack of control or freedom, which is why it is so common in children and adolescents, who, in addition to being chaperoned, lack the mind furnishings – the resources, experience and discipline – to mitigate their boredom.
Let’s look more closely at the anatomy of boredom. Why is it so damned boring to be stuck in a departure lounge while our flight is increasingly delayed? We are in a state of high arousal, anticipating our imminent arrival in a novel and stimulating environment. True, there are plenty of shops, screens and magazines around, but we’re not really interested in them and, by dividing our attention, they serve only to exacerbate our boredom. To make matters worse, the situation is out of our control, unpredictable (the flight could be further delayed, or even cancelled) and inescapable. As we check and re-check the monitor, we become painfully aware of all these factors and more. And so here we are, caught in transit, in a high state of arousal that we can neither engage nor escape.
