Purchase options and add-ons

The widely adopted, now classic book on influence and persuasion—a major national and international bestseller with more than four million copies sold!

In this highly acclaimed New York Times bestseller, Dr. Robert B. Cialdini—the seminal expert in the field of influence and persuasion—explains the psychology of why people say yes and how to apply these principles ethically in business and everyday situations.

You’ll learn the six universal principles of influence and how to use them to become a skilled persuader—and, just as importantly, how to defend yourself against dishonest influence attempts:

  1. Reciprocation: The internal pull to repay what another person has provided us.
  2. Commitment and Consistency: Once we make a choice or take a stand, we work to behave consistently with that commitment in order to justify our decisions.
  3. Social Proof: When we are unsure, we look to similar others to provide us with the correct actions to take. And the more, people undertaking that action, the more we consider that action correct.
  4. Liking: The propensity to agree with people we like and, just as important, the propensity for others to agree with us, if we like them.
  5. Authority: We are more likely to say “yes” to others who are authorities, who carry greater knowledge, experience or expertise.
  6. Scarcity: We want more of what is less available or dwindling in availability.

Understanding and applying the six principles ethically is cost-free and deceptively easy. Backed by Dr. Cialdini’s 35 years of evidence-based, peer-reviewed scientific research—as well as by a three-year field study on what moves people to change behavior—Influence is a comprehensive guide to using these principles effectively to amplify your ability to change the behavior of others.

I really enjoyed reading this book about persuasion techniques and how they are used in sales, marketing, and everyday life. This should be required reading for all high school and college students in order to better help them understand the psychology behind the use of influence. As the author says, these can be used for good or for a very manipulated process by bad actors.

Reviewed in the United States on September 8, 2013
Robert best summarizes the premise of his book: "Although there are thousands of different tactics that compliance practitioners employ to produce yes, the majority fall within six basic categories. Each of these categories is governed by a fundamental psychological principle that directs human behavior and, in so doing, gives the tactics their power. The book is organized around these six principles, one to a chapter. The principles--consistency, reciprocation, social proof, authority, liking, and scarcity--are each discussed in terms of their function in the society and in terms of how their enormous force can be commissioned by a compliance professional who deftly incorporates them into requests for purchases, donations, concessions, votes, assent, etc."

Below are key excerpts from this book that I found particularly insightful:

1- "The impressive aspect of the rule for reciprocation and the sense of obligation that goes with it is its pervasiveness in human culture. It is so widespread that after intensive study, sociologists such as Alvin Gouldner can report that there is no human society that does not subscribe to the rule. And within each society it seems pervasive also; it permeates exchanges of every kind."

2- "The reciprocation rule brings about mutual concession in two ways. The first is obvious. It pressures the recipient of an already made concession to respond in kind. The second, while not so obvious, is pivotally important. Just as in the case of favors, gifts. or aid, the obligation to reciprocate a concession encourages the creation of socially desirable arrangements by ensuring that anyone seeking to start such an arrangement will not be exploited."

3- "Certainly, then, good personal consistency is highly valued in our culture. And well it should be. It provides us with a reasonable and gainful orientation to the world. Most of the time we will be better off if our approach to things is well laced with consistency. Without it our lives would be difficult, erratic, and disjointed. But because it is so typically in our best interests to be consistent, we easily fall into the habit of being automatically so, even in situations where it is not the sensible way to be. When it occurs unthinkingly, consistency can be disastrous."

4- "Once an active commitment is made, then, self-image is squeezed from both sides by consistency pressures. From the inside, there is a pressure to bring self-image into line with action. From the outside, there is a sneakier pressure--a tendency to adjust this image according to the way others perceive us."

5- "The tendency to see an action as more appropriate when others are doing it normally works quite well. As a rule, we will make fewer mistakes by acting in accord with social evidence than contrary to it. Usually, when a lot of people are doing something, it is the right tiling to do. This feature of the principle of social proof is simultaneously its major strength and its major weakness. Like the other weapons of influence, it provides a convenient shortcut for determining how to behave but, at the same time, makes one who use the shortcut vulnerable to the attacks of profiteers who lie in wait along its path."

6- "These results suggest an important qualification of the principle of social proof. We will use the actions of others to decide on proper behavior for ourselves, especially when we view those others as similar to ourselves."

7- "Few people would be surprised to learn that, as a rule, we most prefer to say yes to the requests of someone we know and like. What might be startling to note, however, is that this simple rule is used in hundreds of ways by total strangers to get us to comply with their requests."

8- "Compliance professionals are forever attempting to establish that we and they are working for the same goals, that we must "pull together" for mutual benefit, that they are, in essence, our teammates."

9- "This paradox is, of course, the same one that attends all I major weapons of influence. In this instance, once we realize that obedience to authority is mostly rewarding, it is easy to allow ourselves the convenience of automatic obedience. The simultaneous blessing and bane of such blind obedience is its mechanical character. We don't have to think; therefore, we don't. Although such mindless obedience leads us to appropriate action in the great majority of cases, there will be conspicuous exceptions--because we are reacting rather than thinking."

10- "The evidence, then, is clear. Compliance practitioners' reliance on scarcity as a weapon of influence is frequent, wide-ranging, systematic, and diverse...The first is familiar. Like the other weapons of influence, the scarcity principle trades on our weakness for shortcuts. The weakness is, as before, an enlightened one. In this case, because we know that the things that are difficult to possess are typically better than those that are easy to possess, we can often use an item's availability to help us quickly and correctly decide on its quality. Thus, one reason for the potency of the scarcity principle is that, by following it, we are usually and efficiently right.In addition, there is a unique, secondary source of power within the scarcity principle: As opportunities become less available, we lose freedoms; and we hate to lose the freedoms we already have."

11- "Very often in making a decision about someone or something, we don't use all the relevant available information; we use, instead, only a single, highly representative piece of the total. And an isolated piece of information, even though it normally counsels us correctly, can lead us to clearly stupid mistakes--mistakes that, when exploited by clever others, leave us looking silly or worse."

12- "We are likely to use these lone cues when we don't have the inclination, time, energy, or cognitive resources to undertake a complete analysis of the situation. Where we are rushed, stressed. uncertain, indifferent, distracted, or fatigued, we tend to focus on less of the information available to us. When making decisions under these circumstances, we often revert to the rather primitive but necessary single-piece-of-good-evidence approach. All this leads to a jarring insight: With the sophisticated mental apparatus we have used to build world eminence as a species, we have created an environment so complex, fast-paced, and information-laden that we must increasingly deal with it in the fashion of the animals we g ago transcended."

I didn't even know what I was missing out on in Psychology until I read this book. I had taken a course in college that was not the most interested and I learned things like Pavlov's test with the dog and the bell and steak, where the dog's mouth would water when the bell was rang even if the dog were not presented with a steak. Those types of lessons were interesting but really didn't hit home with me as a person.

Robert Cialdini nails it with Influence: The Psychology of Persuasion. It is such a useful book in daily life: whether you are a normal consumer who is trying to avoid the guilt of sales pitches or a business owner, who is trying to utilize the teachings to take your product to the next level. We are all being manipulated by psychology at every moment, whether we like it or not. I have recently discovered that all of my favorite entrepreneurs, such as Mark Zuckerberg, had majored (or minored) in Psychology in school. Psychology is something that makes us stronger and more complete people for understanding.

I will go through some sections of the book that I found particularly helpful:

-Salespeople who offer a gift before they give you their pitch have subconsciously commanded a returned gift from you because of the theory of reciprocity: gift given is extremely powerful and it always makes the other person feel obligated to give back, even if it is in a different form like signing a petition or buying a product that is presented. As a consumer, you don't want to feel bad for objecting the gift because know you know the power and tactic that they are trying to use on you and you understand that there are no feelings hurt. I turn down these types of offers with a smile on my face now because I'm no sucker.

-Social proof: we are all taking other people's advice without even know it. If you see a homeless person on the street who may have fainted, yet everyone around is walking and going about their day normally, you will think that the person laying on the street is fine. Obviously, someone would have called the cops or an ambulance if there were something wrong. This is the fallacy: because nobody has called since everyone thinks that everyone else already has called. This is a good tactic to know to report these types of problems, like someone screaming for help, for instance. It is also good if you are a victim, so that you can call out to a specific person and point to them and ask them to call a doctor or a police officer, etc. This will better your chances of survival if you are in a dire situation where there are many observers but nobody knows what to do. Also, we purchase items because other people have purchased them. If there is only one can of soup on the shelf at the store it must be good, since others have been buying it as opposed to the other brands. The same goes for tipping at a bar or restaurant's tip jar: more people will feel the need to tip if they are not the only one doing it. I have heard that even some bars put their own starter money in the jar to alleviate the feeling of the tipper being an outsider and will cause more people to tip.

-Attractive people are more likable and agreeable. They are even more likable, still, if they dress in the same style as yourself and match your tone of voice and body language. This is important to know because people will work with you more if they see a little of themselves in your, or if you are so attractable that it is welcoming to them.

-Scarcity is powerful in controlling something's desirability: we often feel more want for something just because of its limited availability and if it is selling out quickly. We feel that we won't have a chance to have it again: which is wrong, yet we let ourselves think this way anyway. Salespeople are notorious for making products seem less available than they really are, just to elicit the sense of urgency when buying. Many times, after a product is bought, the consumer doesn't even remember what made them want it so much in the first place. It is usually scarcity that is a big factor.

Whichever side of the spectrum you are on: provider or consumer, you will find yourself in situations that are made easier with the knowledge that is in this book. It is like knowing how to play chess instead of just letting others take advantage of you on the playing board. If you want to win in life, you will need to know your fair share of psychology. I would argue that this book is a few Psychology courses wrapped into one: because a psychology course will probably reference material from this book anyway and not make it as interesting or understandable. I gave this book to my girlfriend so that she wouldn't get taken advantage of (because women are often an easier target for salespeople). I have also referenced it more than once and wouldn't mind reading it over again. The theories definitely stick and it is one of the books you will remember most in your life.

Reviewed in India on September 13, 2019
Click, Whirr.....Click Whirr....the the human brain keeps ticking away !

Robert Cialdini is spot on with his persuasive book on psychology and gives us brilliant examples and anecdotes on how 'Influence' works on us in the most subtle yet powerful ways possible.

The 6 'Weapons of Influence' as he calls them are Reciprocation, Commitment and Consent, Social Proof, Liking, Authority and Scarcity. Everyday we use one of these tools to soften, convince and sell to others. Conversely, these tools are used on us by others and we fall into traps of bargaining, buying and possessing.

The 'How Not To' at the end of each chapter reveals so much about consumer psychology.

Must read if you are Selling anything...
