Cialdini’s Goal Of Writing His Book Influence: The Psychology of Persuasion

Cialdini spent several years undercover in sales departments of various trades to learn how the best in the business influenced and achieved high levels of compliance. His goal was to identify what made people say yes. And what type of compliance techniques worked best.

Then, disseminate these findings to in his book to the masses so that they would not fall prey to negative uses of influence. But too few regular folk picked up on the book. Cialdini’s persuasion techniques were mostly taught to MBAs and sales people. Who used it in their individual professions to much delight.

Now the time has come for the rest of us to discover how influence and human decision making actually occurs. So we can use it ethically for our benefit. And protect ourselves from their unscrupulous use by crafty salespeople who are only looking out for their profit.

The Science And Method Behind “Influence”

Based on Cialdini’s research, he believes that there are 6 main ways people say yes to requests. In “Influence,” he takes us through each of the 6 decision-making mental shortcuts that people use.

We learn that all these processes occur automatically in our sub-conscious brains. Which is why they are so powerful and universal. It is almost impossible to resist them. Even when you are aware someone is using them against you, you can still fall for them.

The proof? His very book and writing style. Remember he is the Godfather of Influence. When you read his words, you have to realize that he is using the same influence techniques on us, his audience. And he does influence the readers through his writing. Which is what makes the book so readable, in addition to the psychological wisdom it imparts to us.

While that might scare you now that you hear it put this way, fear not. Because if Cialdini’s techniques work so well on us, they prove themselves to be the true influence principles, right? Once you realize this, you will truly grasp the magnitude and importance of his findings.

Simply put, Cialdini’s book “Influence,” is the general theory of relativity for the social psychology world.

The 6 Principles Of Persuasion

In “Influence” we learn from Cialdini that almost all persuasion can be distilled down to 6 main shortcuts that people take when making decisions. They are reciprocation, commitment and consistency, social proof, liking, authority, and scarcity.

Cialdini calls them “weapons of influence” because they are extremely powerful psychological tugs that we all use to make decisions. From ordinary ones like our food choices, to larger choices for what we end up buying or the company we end up working for.

In the book, Cialdini devotes a fairly large chapter to each influence principle. He introduces the persuasion tactic and then through multiple narratives, illustrates how they operate on us. The anecdotes he uses to convey his research are engaging and make you not want to put the book down.

Each chapter ends with advice on how we can avoid being negatively influenced by others through these principles. We learn how to recognize these unwelcome compliance attempts and how to say say no to people who use them against our interests.

The 7th Principle Of Persuasion

A bonus of the New and Expanded 2021 version of “Influence” is a new chapter on Cialdini’s 7th principle of persuasion, unity. He introduced us to it in his recent book, Pre-Suasion. According to Cialdini, unity is the tendency people have to be influenced more by those who are similar to and behave like they do.

“Influence” Can Be A Life-Changing Book

Being a distinguished professor of marketing and psychology, he expectedly backs up his books with extensive examples and citations from psychology journals. This essentially is an example of Cialdini using the “authority” principle of influence on his readers to good effect.

If you want to have a fair chance in our world where everyone wants us to do what they want. And few listen or cater to our needs, then this is a must-read book for you. With Cialdini’s deft way of explaining how to employ these influence techniques in his book, you will notice a shift in your fortunes as an influencer.

Put his persuasion principles to practice in your life and beyond. And in about 6 months to a year you will realize the significance “Influence” has had on your life. It will be unmistakable.
