There certainly are, but the later part of my comment tries to address this by illustrating how nothing is really "out of thin air" (still, the creative jumps from data/knowledge/premises/broken-models to a new hypothesis/better-models are invaluable, and almost always there's a prerequisite of years/decades of hard work to familiarize oneself with the data/old-models on such a level that the insight required for the jump basically comes intuitively "duh just try this, or that, or this helps to fit the data better" - which of course is intuitive to no one else, who did not put in those years).
