On the first day I read this book I wanted to call the author to say "thank you for providing such a great explanation on how people can be easily influenced by some social triggers". I could recognise myself in different situations being exploited by this social triggers, like being influenced to accept some conditions in my job that were against my own interest, being fooled by women or friends or even strangers.
All of us have been exploited by this triggers more often than we think. But now, knowing this triggers I can confidently affirm that it will be much more difficult for exploiters to use them against me as I would be aware of them. So kudos for the author on that.
This social triggers are: social proof, likeliness, commitment, scarcity, authority, liking, reciprocity. The book is well documented on experiments and their outcomes, showing the study conducted by professor Cialdini and how this triggers are consistently used by sales people to profit from them or by exploiters to profit from different situations.
Knowing this triggers not also gives you the ability of not being exploited by them, but also to use them in your favour (but looking for win-win situations). By knowing what people like, you can build your business or products on this social factors, and that is in fact what the most successful people do to earn money, from polititians to business men or bloggers, they all know how to trigger this factors, and you will also know after reading this book.
