A personality trait usually seen as a weakness may have an unexpected advantage hidden beneath the surface.
High levels of creativity may go hand-in-hand with neuroticism.
This may be because the area of the brain linked to creativity also tends to promote overthinking and worry.
Neuroticism is characterised by negative thinking in a range of areas.
For many years, researchers believed that highly neurotic people had a heightened sensitivity to threat.
This doesn’t fit the facts, though, explains Dr Adam Perkins, the study’s first author, said:
“…it’s pretty difficult to explain neuroticism in terms of magnified threat perception because high scorers often feel unhappy in situations where there is no threat at all.
The second problem is, there’s literature showing neuroticism scores are positively correlated with creativity; and so why should having a magnified view of threat objects make you good at coming up with new ideas?”
Active imagination
The neuroscientists noticed, however, that neurotic people show high activity in part of the medial prefrontal cortex.
This area also plays an important role in self-generated thoughts.
Dr Adam Perkins said:
“It occurred to me that if you happen to have a preponderance of negatively hued self-generated thoughts due to high levels of spontaneous activity in the parts of the medial prefrontal cortex that govern conscious perception of threat and you also have a tendency to switch to panic sooner than average people, due to possessing especially high reactivity in the basolateral nuclei of the amygdale, then that means you can experience intense negative emotions even when there’s no threat present.
This could mean that for specific neural reasons, high scorers on neuroticism have a highly active imagination, which acts as a built-in threat generator.”
Dr Perkins said the theory may help explain some of the positive aspects of neuroticism:
“We’re still a long way off from fully explaining neuroticism, and we’re not offering all of the answers, but we hope that our new theory will help people make sense of their own experiences, and show that although being highly neurotic is by definition unpleasant, it also has creative benefits.
Hopefully our theory will also stimulate new research as it provides us with a straightforward unifying framework to tie together the creative aspects of neuroticism with its emotional aspects.”
