How Do We Measure Creativity?

 Over the week I have been thinking about measuring creativity and I didn't expect it to be difficult. As we know creativity is an ambiguous term and how can we measure something like that!? With creativity, there can be no right or wrong answers but maybe we can measure the thought process rather than the creative work. For my research study what I will do to measure creativity is to ask about their thought process in creating a photo. The way I see it, someone who isn't creative can take photos without thought as someone who is more creative would take more time thinking about the photo. This way I can avoid measuring their work but measure their thought process.
