the ‘Ben Franklin effect’. The eighteenth-century American founding father, polymath and politician had problems with the animosity of a rival Pennsylvania legislator who was a sort of Sarah Palin to Franklin’s Barack Obama. This legislator’s enmity was causing the great man difficulties, so how could he bring him round? Anticipating the sales techniques and cognitive science of three centuries later, the clever Franklin did something quite unexpected – he asked his rival for a favour.
Franklin knew that the man had a rare book in his library, so he asked him if he could borrow it for a few days. He returned it a week later with a note of thanks. In his autobiography, Franklin reports with satisfaction how when they next met, his rival spoke to him for the first time in a civil and even friendly way. He went on to offer Franklin any other help he needed and gradually their relationship flowered into a friendship that lasted throughout their lives.
