[W]e humans are the last to notice our own limited nature. In seven words, Shakespeare sums up a good portion of the findings of modern psychology: “most ignorant of what he’s most assured.” A recurring discovery of social and cognitive psychology is that human beings are absurdly overconfident in their own knowledge, wisdom, and rectitude. Everyone thinks that he or she is in the right, and that the people they disagree with are stupid, stubborn, and ignorant. People reliably overestimate their own knowledge, and misjudge their own accuracy at making predictions. A common theme of both Shakespeare and modern social psychology is the human species’ overconfidence.
Remarkably, Shakespeare identifies this darker side with what we now know to be our evolutionary ancestry. With “like an angry ape,” he compares us to our primate cousins (an impressive 250 years before Darwin). What a striking simile for human impetuousness and foolishness! We tend to dignify displays of human emotion; presented with a burst of feeling, we seek its cause. But an angry ape we look on with amusement—the rage is infantile, comic, the result of ape’s own limited understanding. The detached amusement at the absurdity of human acts continues in the next line—“plays such fantastic tricks before high heaven.” “Playing a trick” refers to something lighthearted, trivial. Our feeble attempts at wisdom and justice, our petty exercise of power, appear ridiculous to wiser, celestial onlookers.
