Paul Silvia: The 2015 paper was our first toes-in-the-water. The whole brain view is really a good way to think about it. Traditionally with creativity and brain work, investigations have addressed: What’s the creative part? Where’s creativity in the brain? What’s the part that lights up?
And traditionally, the view has been: The right side is the creative part. But there’s really no part or piece or even single system. Creativity is a very complex thing. Our earlier study was really a pilot study. We had a small number of people and we were pretty limited in how we were looking at creativity. People weren’t especially selected because they were creative or eminent or accomplished. It was kind of a proof of concept. There was enough to suggest that we were on to something with the idea.
Suzan Mazur: But why were all of your participants in that first study right-handed?
Paul Silvia: The world is not fair to lefties, Suzan.More.
No, it isn’t. In many cultures, children have been tied or beaten to force right-handedness. So the actual number of natural lefties may not be easily known.
But some of us ask, if people are totally right-handed, why can most people clip their right fingernails? How can most women polish their right-hand nails?
