This book is good to read and I found it very useful because it explains some of the tricks used around us that influence our decision making. I think that is important for us to be aware of such weapons used not only by professionals but by random people within our personal lives. Reading and reflecting about it helps us to detect such mechanisms allowing a more reasonable way to deal with it. I think the autor uses very simple examples to illustrate various situations in which influence is used and shows how to say no, but shows how it works too, which is interesting for any person working in marketing or in communication in general. I enjoyed it and think that is important reading.

There are several marks of a great book. The first is if the information seems so intuitive that we wonder why we didn’t think of it and synthesize it ourselves. The answer, of course, is that it’s not- or else we would have done it already. But when we feel that, that means the information is presented so forcefully, so systematically, that we feel it to be true- it has hit our brain and our gut.The second mark of a good book is if it forces us to pursue or wonder about additional lines of inquiry. The book sends our mind spiraling outward and into the world.   

And the final mark is if it also forces us to think about ourselves, to look inside, to question who we are. A great book reshapes our own actions and conceived notions; it turns us inward and into our tangled minds.

Influence, to its rare credit, accomplishes all three.

It answers the very simple question of how are we persuaded to action?

The answer lie with several factors: reciprocation, commitment and consistency, social proof, liking, authority and scarcity. Cialdini details each of these considerations with academic studies and real life examples. You’ll recognize some of them like Milgram’s shock experiment and Kitty Genovese’s murder. He does so in an accessible and intuitive way. And in doing so, equips the reader to defend themselves against, “compliance professionals”, and, if so inclined, to wield them ourselves.

The one thing I wish he had discussed more in depth is the influence of the Internet and the democratization of information and authority. But I guess that’s too much to ask for. Those questions unanswered, after all, send me into myself and into the world, searching for the answers to the questions he began to unlock in me.

A powerful book indeed.

Influencepg. 4- a well known principle of human behavior says that when we ask someone to do up a favor we will be more successful if we provide a reason.   

Pg. 33-34 – or, more generally, why should it be that small first favors often stimulate larger return favors? One important reason concerns the clearly unpleasant character of the feeling of indebtedness. Most of us find it highly disagreeable to be iota state of obligation. It weighs heavily on us and demands to be removed.

Pg. 52- once we make a choice or take a stand, we will encounter personal and interpersonal pressures to behave consistently with that commitment. Those pressures will cause us to respond in ways that justify our earlier decision. We simply convince ourselves that we have made the right choice and, no doubt, feel better about our decision.
we all fool ourselves from time to time in order to keep our thoughts and beliefs consistent with what we have already done or decided. For instance, immediately after casting a ballot, voters believe more strongly that their candidate will win.

Pg. 99- the principle of social proof. This principle states that we determine what is correct by finding out what other people think is correct (Lun et al., 2007). The principle applies especially to the way we decide what constitutes correct behavior. We view a behavior as correct in a given situation to the degree that we see others performing it.

Pg. 100- Cavett Robert said: “Since 95% of the people are imitators and only 5% initiators, people are persuaded more by the actions of others than by any proof we can offer.”

I started reading this book for work – one of the things I’m supposedly working on this year in my ability to have influence on project decisions and be able to effectively provide input. I figured this would be unspeakably boring and decided to read some vampire stuff at the same time to get me through it.I actually loved this book, though. He talks about all these methods that people – typically sales professionals – use to influence customers to buy more stuff. And I fall for this shit ALL THE TIME.   

Take reciprocity, for example. The person trying to sell something – or get people to donate something – gives a small gift, and the rate at which people actually do buy or donate skyrockets. When I get preprinted address labels? I feel guilty for not donating, even though I don’t want them in the first place. Or when I was in LAX and got accosted by some dude with a nametag who gave me directions and then asked for a donation? I totally gave it. Resentfully, but I gave it.

Another big one for me is commitment and consistency. If I make a commitment to buy something, or do something, I will almost always follow through on it, even if I no longer want to and the consequences for not doing so are minor. I don’t want to look like a unreliable flake, even to myself.

He also goes through a lot of other things that influence people, such as social proof (what everyone else is doing), scarcity, authority, etc.

I really enjoyed this. I learned a lot about why I do certain things and how to defend myself against nefarious salespeople who try to convince me to buy stuff I don’t want.

Why do we buy stuff we don’t need? Why do we comply with requests that “feel wrong” or make us uncomfortable? In this book, Arizona State professor Robert Cialdini examines the social psychology behind compliance, with the goal of helping us understand the “weapons of mass persuasion” that advertisers and salespeople can so easily use against us.Cialdini went undercover in the late 1970s/early 1980s to do research about compliance techniques. He apprenticed himself to Amway salesmen and car dealers, and mined their secrets. Based on his findings, Cialdini isolates six rules of human behavior that “compliance professionals” exploit in order to get us to purchase what they’re selling, to join their cult, or in other ways to go along with their goals. This is fascinating stuff, relayed in a romping, friendly, slightly nerdy voice that keeps the content accessible and appealing.   

The book first came out in 1984, and was most recently revised in 2007 (though it does not seem that substantive changes were made). My only beef with the 2007 edition is that it contains lots of very 1980s-looking black-and-white photos. Some of them are certainly still relevant, such as ads from that time period, but I would have liked to see newer visuals mixed in with them. That would have better underscored Cialdini’s point that these techniques of persuasion are still widely used today.
