There are three sorts of scientists: the journeyman, the lover, and the egoist. Journeymen scientists do not let their imagination run wild with possibilities. They are content with the small steps that will lead to the end of the next block. They are competent, but boring. The scientific lover are those who, like Sherlock Holmes, best enjoy scientific research when the game's afoot and realize that scientific discovery is merely puzzle-solving at its best. They are often brilliant, and may or may not be reliable. The scientific egoists find little joy in their search for truth, but rather merely use research as a means to an end, an end filled with money, power or prestige, or perhaps, some or all of these together. They are not nice people: they often spy on research competitors while simultaneously feeding their competitors false information. They are also very cliquish.
