I would love to see your system/tool for predicting future creativity. Or some evidence that creative people are more likely to be successful dropouts. The evidence I've seen at least suggests the biggest predictor of success is grit: the ability to grind through and stick with something longer than others. Now, you might argue the measure of success also needs to be updated to accommodate your "creative people" hypothesis, but then you're basically designing the question to meet your predefined outcome.
