From Salon:
For example, Flintoff tells a story about how he got very worried about global warming and decided the only solution was for everyone to grow their own produce. It wasn’t enough to just change his own habits — everyone would need to pitch in to make a dent in carbon consumption. He wanted to start with the people living in his section of London, but rather than harangue his neighbors, Flintoff devised a plan. First, around harvest time, he brought an armload of ripe tomatoes around to his neighbors’ doors, explaining he couldn’t possibly eat all the fruit he had grown. They accepted gladly. Phase I, Buttering Up, was a success. The next spring, he brought around tomato seedlings to the same neighbors. He had some cover story about having planted too many, and asked if they would be interested in growing their own tomatoes this year. Remembering the good tomatoes from last year, most accepted the plant. He had essentially tricked his neighborhood into growing its own tomatoes.
Devious? Maybe. Effective? In Flintoff’s case, yes. Although Flintoff doesn’t advise trickery in every case, he has some ideas about how to convince others to join in your righteous mission — including, paradoxically, offering them a gracious way out. “People do like to give advice or help,” he said. “The only time they don’t feel that happy is if they feel cornered.”
