"Despite the near-universal cult of happiness and unprecedented material wealth, happiness and life satisfaction in Western societies has not improved for decades.
It’s time to re-assess the role of bad moods in our lives. We should recognise they are a normal, and even a useful and adaptive part of being human, helping us cope with many everyday situations and challenges."
Psychological benefits of sadness
There is now growing evidence that negative moods, like sadness, has psychological benefits.
To demonstrate this, researchers first manipulate people’s mood (by showing happy or sad films, for example), then measure changes in performance in various cognitive and behavioural tasks.
Feeling sad or in a bad mood produces a number of benefits:
- better memory In one study, a bad mood (caused by bad weather) resulted in people better remembering the details of a shop they just left. Bad mood can also improve eyewitness memories by reducing the effects of various distractions, like irrelevant, false or misleading information.
- more accurate judgements A mild bad mood also reduces some biases and distortions in how people form impressions. For instance, slightly sad judges formed more accurate and reliable impressions about others because they processed details more effectively. We found that bad moods also reduced gullibility and increased scepticism when evaluating urban myths and rumours, and even improved people’s ability to more accurately detect deception. People in a mild bad mood are also less likely to rely on simplistic stereotypes.
- motivation Other experiments found that when happy and sad participants were asked to perform a difficult mental task, those in a bad mood tried harder and persevered more. They spent more time on the task, attempted more questions and produced more correct answers.
- better communication The more attentive and detailed thinking style promoted by a bad mood can also improve communication. We found people in a sad mood used more effective persuasive arguments to convince others, were better at understanding ambiguous sentences and better communicated when talking.
- increased fairness Other experiments found that a mild bad mood caused people to pay greater attention to social expectations and norms, and they treated others less selfishly and more fairly."
