Understanding mistakes or exploring creativity?

This post from 'reckon' that I'm following on twitter is fascinating in itself. Does the creative use of language generate different changes in brain activity in the reader or listener? Can the creative use of language casue measurable, physical and profound effects in the human brain? The subject for this experiment is Shakespeare, who had a habit of using nouns as verbs or adjectives for example. These have an 'electric' effect on the reader/listener, as the unusual or even unique use of these words jump out at them. To find out what they did, read about it here.

But what also struck me in reading this was the fact that so many questions are framed around mistakes, incapacities and problems. There's nothing wrong with this in iteslf, but there are perhaps so many more wonderful discoveries to be made by framing questions around positive things in the way this experiment does. Is this down to some innate firefighting, or crisis-response human condition? To quote (or, more precisely, paraphrase) one of those motivational speakers, 'if only we could harness our breathtaking capacities to survive in the face of danger, and use them to imagine and achieve a positive peaceful future, what wonder could we see in the world?
