Nobel Prize–winning neuroscientist Eric Kandel took a risk and studied the tiny sea slug Aplysia based in part on a lesson he had learned from his wife regarding their recent marriage, which encouraged him to trust his intuition: “Denise was confident that our marriage would work, so I took a leap of faith and went ahead. I learned from that experience that there are many situations in which one cannot decide on the basis of cold facts alone—because the facts are often insufficient. One ultimately has to trust one’s unconscious, one’s instincts, one’s creative urge. I did this again in choosing Aplysia” (Kandel, 2006, p. 149).
