BBC: Why it pays to be grumpy and bad-tempered

Next the two teams were pitched against each other in a game designed to test their creativity. They had 16 minutes to think of as many ways as possible to improve education at the psychology department. As Baas expected, the angry team produced more ideas – at least to begin with. Their contributions were also more original, repeated by less than 1% of the study’s participants. [...]

In essence, creativity is down to how easily your mind is diverted from one thought path and onto another. In a situation requiring fight or flight, it’s easy to see how turning into a literal “mad genius” could be life-saving.

“Anger really prepares the body to mobilise resources – it tells you that the situation you’re in is bad and gives you an energetic boost to get you out of it,” says Baas. [...]

Then in 2010 a team of scientists decided to take a look. They surveyed a group of 644 patients with coronary artery disease to determine their levels of anger, suppressed anger and tendency to experience distress, and followed them for between five and ten years to see what happened next.

Over the course of the study, 20% experienced a major cardiac event and 9% percent died. Initially it looked like both anger and suppressed anger increased the likelihood of having a heart attack. But after controlling for other factors, the researchers realised anger had no impact – while suppressing it increased the chances of having a heart attack by nearly three-fold. [...]

In some situations, happiness carries far more serious risks. It’s associated with the cuddle hormone, oxytocin, which a handful of studies have shown reduces our ability to identify threats. In prehistoric times, happiness would have left our ancestors vulnerable to predators. In modern life, it prevents us paying due attention to dangers such as binge drinking, overeating and unsafe sex.
