The book "Influence" is one of Cialdinni's most famous books, which has swept the world's top 30 rankings and is the most cited in today's social psychology. This book has been sold for a long time because of the first book I bought while listening to Fan Deng, and this book is very versatile. The degree of application may be beyond your imagination, and we can basically use this book in our daily life and Xi, so we should read this book well and systematically. 
The author of the book begins with a turkey story. Mother Turkey is a very dutiful mother and she loves her little turkeys very much. It goes to great lengths to clean the coop, clean up, provide a comfortable living space for the children, and if the children are hungry, it feeds the children in time to give the little turkeys a full meal. It can be said that this mother is very conscientious and provides meticulous care and feeding to the little turkey. But all these activities have a premise that is too simple to be simpler, that is, the little turkey makes a "chirp" sound, which is like a command, or like a switch, as long as the little turkey makes this sound, the mother turkey will come forward to take care of the little turkey. If the baby turkey can't make a "chirp" sound, then the mother turkey won't notice the little turkey, and the probability of the little turkey surviving becomes very low.
From here we can see that the password or switch that makes the mother turkey a very qualified mother is the chirp of a little turkey, and without the chirp of a little turkey, a mother turkey cannot actively perform her duties as a mother. 
Later, scientists did an even more meaningful experiment. Skunks are the natural enemies of turkeys, one day, scientists put a toy skunk outside the turkey nest, when the mother turkey found the skunk toy, it mercilessly began to peck at the skunk, trying to find a way to drive away the skunk, so as to ensure the safety of the baby turkey. Although it is only a toy skunk, the mother turkey is still a very qualified mother and fulfills her obligation as a mother, which is to drive away the skunk in time to ensure the safety of the baby turkey. The scientists then installed a device in the stomach of the toy skunk that made a "chirp" sound, and then the skunk toy could make a "chirp" sound at any time, and then placed the skunk outside the turkey nest. When the turkey heard the "chirping" sound of the skunk, it did not have the previous expulsion action at all, but quickly put the skunk toy under its wings, carefully brought the skunk toy into its nest, and cared for it like any other little turkey. At this time, the mother turkey has already regarded this toy skunk that can make a "chirping" sound as her own child, and has put the fact that the skunk is her natural enemy out of the clouds. The root cause of such a change in the mother turkey before and after the toy skunk is the "chirp" sound, which determines how the mother turkey treats the toy skunk. Influence Cialdini We call the behavior pattern of the mother turkey because of the "chirping" of the turkey as a fixed behavior pattern, which is easy to exploit, if the skunk can think and imitate the "chirp" of the small turkey, then the skunk is very easy to catch the little turkey. This pattern of behavior of the mother turkey works normally in most cases, unless these scientists are encountered to do experiments, otherwise, in most cases, this behavior pattern turns out to be good. If the little turkey can't make a chirping sound, it is possible that the little turkey has a physical problem, then it will not get the normal care of the turkey mother and lose its life, which is also the result of natural selection, who makes the little turkey not crow. It's not just lower animals that have this pattern of behavior, but we, as higher animals, have a similar pattern of behavior.
Many drivers will have this feeling, when you want to plug in, if you say hello to the car behind you, or say hello, then the probability of the car behind you is more likely to give way to you. If you have to plug and do nothing, the car behind you will basically not give way to you. This is our fixed pattern of behavior, if the other party is friendly, we can also give in, after all, it is not a big deal.
When you are in a hurry to buy a ticket, if you rush to go, then the people behind you will definitely be unwilling. But if you greet the big brother of the person who was plugged in advance, and say that I am really in a bit of a hurry, and I won't be able to catch the car if I am late, then as a person, there will be no problem for you to add the plug.
