Have you heard the story of how Thomas Edison screened potential new research assistants? Legend has it that he would invite applicants out for a meal and order soup for the table. As the story goes, he did this to see how the applicants approached the situation. Did they make assumptions about the blandness and season the soup before tasting it, or did they allow themselves to taste it first and decide afterward if seasoning was necessary? Edison’s purpose was to weed out those who seasoned before tasting, reasoning that those who relied on assumptions would not produce the kind of open-minded Scientists and Engineers he needed in his laboratory. The lesson from this tale is to think about how best to evaluate a candidate for a potential position on your team.
