The sympathetic plot—featuring a goal-directed protagonist who confronts obstacles, overcomes them, and wins rewards—is ubiquitous. Here, I propose that it recurs because it entertains, engaging two sets of psychological mechanisms. First, it triggers mechanisms for learning about obstacles and how to overcome them. It builds interest by confronting a protagonist with a problem and induces satisfaction when the problem is solved. Second, it evokes sympathetic joy. It establishes the protagonist as an ideal cooperative partner pursuing a goal, appealing to mechanisms (...) for helping. When the protagonist succeeds, they receive rewards, and audiences feel sympathetic joy, an emotion normally triggered when beneficiaries triumph. The capacities underlying the sympathetic plot evolved for learning and cooperation before being co-opted for entertainment. (shrink)
