For the Coolidge Effect to take place, though, an individual has to appreciate the value of novelty and be daring enough to go after it. You have to be willing to leave the comfortable shelter of an established order—sometimes actually leave, as in leave home, and sometimes leave metaphorically, as in step outside the bond. There’s risk involved in any such adventure. You may have to poach another individual’s mate, perhaps over the objections of that individual, who may engage in some pretty serious mate guarding.
