Invert, always invert.
The book reminded me of this bit of wisdom from German mathematician Carl Jacobi.
Often, when we want to influence other people and create change within an organization, we believe that heightening the appeal of the idea is the most effective way to go about doing this. For example, if we’re trying to persuade someone to quit smoking, we might attempt to do this by providing them with more evidence that this habit will eventually lead to lung cancer. Clearly that won’t work, just like how providing more evidence seldom convinced people to wear masks during COVID.
The book’s main point is that although fuel is important to initiate change, more often that not, it is actually the “friction” that is stopping people from taking action. So for the COVID example, it’s not that people don’t believe that masks work (although some don’t); it was that they felt like their freedom was being taken away from them. So the more that the media told them that they were stupid or inconsiderate for not wearing masks, the more obstinate they were to changing their behavior.
The book goes over 4 key sources of friction and how to overcome them. At the end, the author gives some case studies to show how solving for these friction points motivated change.
Overall, the book was concise and I learned a few things from it. Would recommend
