Darwin even employed his new science to the history of his own life, as Sulloway explains: “Charles Darwin understood this human predilection for reaffirming the status quo. In his Autobiography he noted how quickly he tended to forget any fact that seemed to contradict his theories. He therefore made it a ‘golden rule’ to write this information down so that he would not overlook it. Like Darwin’s golden rule, hypothesis testing overcomes certain limitations in how the human mind processes information.”
