First, I would like you for writing this piece about curiosity and pointing out the importance of the excel in knowledge. You mention that there is no research on sparking/triggering adults curiosity, I have no idea about that, but, I would like to mention that there is a book I read few years back called Why? What makes us curious. By Mario Livio. I thought you may take a look at it since you have your dissertation on curiosity.
