Testimonials and recommendations

“There is arguably no more important book in the world of persuasive selling than Robert Cialdini’s “Influence: The Psychology of Persuasion”. With the rise of online marketing, it was, therefore, only a matter of time before the principles of influence that Mr. Cialdini talked about began to be used by online business owners and marketers to increase sales and conversions on their websites.”

 “Dr. Robert Cialdini is the seminal expert in the rapidly expanding field of influence and persuasion.”

"Cialdini, one of the greatest social thinkers of our time."

“Robert Cialdini is the Benjamin Franklin of research on influence–a keen observer of human nature, great writer, minter of pithy phrases, and clever experimenter who’s able to capture lightning in a jar.”

“Robert Cialdini is the world’s foremost expert on persuasion and the author of the book, “Influence: The Psychology of Persuasion” which is a classic no adviser should go without reading.”

“This program will help executives make better decisions and use their influence wisely… Robert Cialdini has had a greater impact on my thinking on this topic than any other scientist… The best popular book that demonstrates six or eight ways in which the quirks of your own mind will frequently prove dysfunctional to your best interests is Cialdini’s Influence.”

“His presentation was stirring and full of information to help in the influencing decisions and more specific in getting closure on your ideas and services.

Our agents are now better positioned to influence their clients — in an ethical manner — to make better buying decisions. We could not be happier with his presentation.”

“Bob Cialdini was the top-scoring speaker at our Financial Advisers Conference, where some awarded him scores above the maximum. Additionally, he was at the top of the speakers of the European Annual Meeting. Bob’s ability to bring together fundamental behaviours of vital importance, with the logic and scientific evidence that support his concepts, made the presentations particularly powerful. He presented in an attractive and entertaining way that held the interest of the audiences throughout both conferences.”

“Dr. Cialdini was a perfect fit for our event. He and his team were incredible to work with leading up to the event and they delivered as promised, and more! Dr. Cialdini was polished and professional on stage, delivering a message tailored to our audience, and was gracious and kind to our attendees following his presentation. From our initial booking through Nancy Vogl Speakers Bureau, through Cialdini’s stage presentation, to the Q&A sessions and attendee photo ops, we could not be more pleased with Dr. Cialdini!”

“Anybody writing about persuasion and influence today stands on Cialdini’s shoulders. If you’ve got time for only one book, this is it.”

“After Dr. Cialdini’s program, the noise of praise was almost deafening.”

“Dr. Cialdini’s book was the foundation for much of what we spearheaded in the FBI that moved professional negotiators towards becoming crisis interveners. We copied very heavily from Cialdini’s book. We looked at ways people gain influence with another and it is all about relationship building, earning trust and demonstrating a genuine interest in their issues and concerns.” 

“Dr. Cialdini amazed our audience with his immense knowledge on the psychology of persuasion. His presentation style is relaxed, intense and ‘pleasantly confronting’. A brilliant mix! Over 350 managers could not get enough of Dr. Cialdini’s highly interesting lectures. After his last talk, he received a standing ovation, which is very rare in Holland. It was a sign of deep appreciation for his contribution to the success of the day.”

“Dr. Cialdini was the top speaker we’ve ever had…in or out of the organization. They loved him.”

“Both your content and style of presentation make it easy for one to relate your ’Principles of Influence‘ to virtually any business or endeavor.”

“Dr. Cialdini’s program at the Training Leadership Summit was most impressive. His passion for translating science into ethical business actions gave these industry leaders powerful tools to use immediately. This program is a must for those serious about effective ethical influence.“ 

“The Training Directors’ Forum is the third event Robert Cialdini has keynoted for us and each time he has done an outstanding job—providing ethical and actionable information on the ‘Science of Influence’ that our participants can immediately apply in their work.”

“We’ve known for years that people buy based on emotions and justify their buying decision based on logic. Dr. Cialdini was able, in a lucid and cogent manner, to tell us why this happens. Our agents are now better positioned to influence their clients — in an ethical manner — to make better buying decisions. We could not be happier with his presentation.”

“Not only was his lecture and the subsequent discussion fascinating but for weeks afterward I heard people here and elsewhere referring to his insights and examples. My sense is also that Robert’s work is being taken very seriously in Government so I hope that his research will come in time to be more fully reflected in public policy.”

“Robert Cialdini, through his intensive research, has clearly shown that it is possible to increase the efficiency and effectiveness of persuasion to bring about amazingly positive results.” 

“I want to express my appreciation for your excellent presentation at The Forum on Executive Decision Making and Influence… the audience was composed entirely of senior executives from major U.S. and Canadian companies… The evaluations were in the ’excellent‘ range and you received more mentions as ’The part of the program I liked most‘ than any other speaker — quite an accomplishment given the competition!”

“There is no more famous influence expert than the ‘Godfather of Influence’: himself, Robert Cialdini. He is the author of the 1984 book that single-handedly revolutionized the study and practice of INFLUENCE.”

“Bob Cialdini is the most brilliant student of influence and negotiation I’ve encountered. If everything were on the line in a negotiation, I can’t think of anyone I’d rather have advising me.”

“I have admired Dr. Cialdini’s research and gift for communication for nearly 20 years since I first read “Influence”; for this reason, my expectations were already quite high. I am so pleased to say that this was one of those moments where the saying “never meet your heroes” proved to be entirely incorrect. Dr. Cialdini was every bit the authority in his field: deeply knowledgeable and ready with insightful answers to our questions, and thoroughly engaging as a presenter. What made his visit to our company especially enjoyable for my colleagues and I was his genuine interest in our work, his enthusiastic support while we tested ideas and workshopped options based on his principles, and his authenticity and warmth throughout the day.”

“Dr. Cialdini held our audience ‘spellbound’ for hours. His advice was both strategic and practical and was geared perfectly for our audience from about 40 countries. His principles were put into practice by the delegates immediately.”

“Dr. Cialdini’s ability to make the science of Influence understandable and immediately useable is only exceeded by his contagious knowledge and passion for the subject. Dr. Cialdini’s message is a must business investment for healthcare or leadership!”

“Bob’s work is so important to what we do, it’s like walking on the beach and finding a bottle with a genie in it.”

“Dr. Cialdini’s program was the best I have taken in 25 years of taking courses. Not a day goes by that I don’t apply one or more of the principles in my work and with my family. This material is like a hidden gem which I am glad that I discovered!”

“Dr. Robert Cialdini has played an integral role in the development of our high-potential leaders. His practical insights and real-world perspectives have challenged our executives to step back and reassess their global leadership and influence skills. He provides an important link in the development of our future leaders.” 

“Dr. Cialdini was one of the best speakers we have ever had in the eight years of our Institute! The audience was captivated by his message and style. His information was not only interesting, but had substance. Dr. Cialdini provided practice information that could easily be utilized by the audience in the future.”

“In short, Dr. Cialdini is a great speaker with a great topic for today’s savvy businessmen and businesswomen. I recommend Dr. Cialdini to any professional group seeking to inform and enthuse its members.”

“Our people have had a lot of different training classes, but this one is different. The six principles of influence appear to be simple, but the more we learned, the more we realized that this course is really a tight little system that allows us to think in different ways. This Principles of Persuasion course was excellent for our Senior Managers, customer service directors, and salespeople. We saw a measurable difference right away. The only problem is, now the word has spread and everyone wants it.” 

“The Principles of Persuasion workshops have been very useful indeed. Our colleagues here at Schering Health Care became much more personally effective whether they are new to their role of very experienced. The POP really helped our selling model for instance and really helped increase one’s personal impact without being too rigid and conformist to a model. People here are very enthused. Thank you once again.”

“If you have a choice, don’t miss the opportunity to expose your people to this man. His work, his science, his ethics and his method for putting it all together are an experience you can’t get elsewhere.”

“Thanks for your excellent presentation on the strategy of influence and change in attitude. It was very well received by our distributors and Hercules representatives, and I’m sure will create a better thought process by all in selling and in management.”

“This book is the de facto standard to learn the psychology of persuasion. If you don’t read it, I hope you enjoy pounding your head against the wall and throwing away marketing dollars.”

“Dr. Cialdini is by far our best-rated speaker…. again.” 

“Robert Cialdini, through his intensive research, has clearly shown that it is possible to increase the efficiency and effectiveness of persuasion to bring about amazingly positive results.” 

“You promised, and delivered! People were talking about Dr. Cialdini’s presentation. It gave our whole CMO event an important added dimension beyond the “usual” marketing strategies and tactics that most sessions emphasize.” 

“I am sure that the conclusions you draw will have a major influence on management and sales practices.”

“Dr. Cialdini, I was concerned that because my sales team is very senior, sophisticated, and experienced, if you did not keep their attention, they would simply walk out, get on their Treos or start taking phone calls. I was most pleased that they stayed, were engaged and, from their responses, now months afterward, found: new, useful, long-term and important lessons to make these ‘old pro’s’ even better. Mission accomplished!”

“The feedback from the audience so far has been great – they really loved Dr. Cialdini!”

“The message given in your presentation is just what our people needed to confirm that the psychology of influence can be learned… If these messages are applied, then our objective of creating a more successful business will have been met.”

“Very rarely do I hear a speaker whose message stays with me after I leave the session… I am still amazed how often I am drawn to his words…informative, motivational, interactive and downright helpful with everyday life situations. I immediately put into practice some of his techniques, and found them very beneficial.”

One attendee remarked after his address that hearing his presentation was time and money well spent to attend the entire conference.”

“After Dr. Cialdini’s program, the noise of praise was almost deafening.”

“He blew everybody away. They were thrilled. In fact, afterward, one of our lead people pulled me aside and said he came into this program thinking he had been oversold about Dr. Cialdini’s effectiveness. He admitted he was wrong, and ended up taking 6 pages of notes on ways he can apply this information immediately to his work. And yes, you can quote me on this.”

“An instant classic.”

“Mind-blowing.”

“Cialdini book is fascinating and immediately actionable, highly recommended.”

“Drift says the one book you need to read is Influence by Robert Cialdini. It's one of the best business books out there because it accurately explains buyer behavior — and if you're in the business of selling, that's kind of a big deal.”

“Utterly fascinating.”

“The Psychology of Persuasion was written by Robert Cialdini, a world-renowned psychologist who has previously worked at many universities, including Stanford. His principles have stood well the test of time, and this book has topped the New York Times Bestseller List.”

“Robert Cialdini, PhD, has been the go-to psychology expert in marketing since his best-selling book Influence: The Psychology of Persuasion was first published in 1984.”

“This one is a deep dive into behavioral science and human psychology. It’s shocking, entertaining, and introduces you to the fallibility of your own brain in quite a delightful way.”

“I have been using this in class at Stanford for over 25 years, and I have had dozens of students say to me years later 'I don't remember much else about your class, but I still use and think about that Cialdini book.'”

“Behavioral science is widely accepted. Behavioral economists Daniel Kahneman and Richard Thaler have won Nobel prizes for their work, and both penned bestselling books. Robert Cialdini's classic, Influence, has sold millions of copies. Governments around the world have set up "nudge units" to apply behavioral science to improve program outcomes, and some corporations are doing the same.”

“Cialdini does a magnificent job and you’re all going to be given a copy of Cialdini’s book. And if you have half as much sense as I think you do, you will immediately order copies for all of your children and several of your friends. You will never make a better investment.”

“Robert Cialdini has had a greater impact on my thinking on this topic than any other scientist.”

“Shockingly insightful.”

“Cialdini is the expert on influence. His research reveals principles that any leader, or any person for that matter, can apply.”

“I just read this book for the 3rd time. It’s the best book there is to understand the cognitive biases we all use to make decisions.”

“It taught me so much about marketing and human psychology. I keep referring back to that book all the time. It has been instrumental in inspiring the marketing strategies I used to propel Rails and Basecamp.”

“I’m not teaching anyone to be evil. But we need to understand what works at the highest level: those who survive due to influence.”

“In his global bestseller Influence, Professor Robert Cialdini transformed the way we think about the craft of persuasion. Now he offers revelatory new insights into the art of winning people over: it isn't just what we say or how we say it that counts, but also what goes on in the moments before we speak.”

“Drawing on the latest research, and packed with fascinating case studies, Pre-Suasion is a masterclass in enhancing your powers of influence.”

"For anyone interested in the science of persuasion, psychology professor Robert Cialdini has been the expert of choice since the 1970s. During his long career at Arizona State University, he has studied everything from the ways blood banks attract donations to the reasons why some people pick up litter and others don’t. Cialdini’s best-known book, Influence, has sold 2.5 million copies worldwide. It remains one of Amazon’s top 500 titles, 31 years after its debut."

“It’s pure gold for product marketers.”

“This book is the de facto standard to learn the psychology of persuasion. If you don't read it, I hope you enjoy pounding your head against the wall and throwing away marketing dollars.” 

“This the most important book a marketer can read," says Kawasaki. "Learn the social psychology principles that will make you a more effective communicator, leader, and parent. If you don't change a few things about your business after reading this book, you're probably hopeless."

“This book is already a classic in terms of how to influence people and persuade them to do what you want, and how to protect yourself from persuasion by others. These are two must-have skills for leaders and you should continually work on improving them.”

“Robert Cialdini is the most influential person in the world. And by that I mean, he wrote the book, 'Influence', which sold three million copies and defines the six critical aspects of all influence. Now he has a new book, “Pre-Suasion“, going 10x deeper into the concepts of persuasion.”

“This is not an optional read if you're in business or want to be in business. If you go into any category, niche or field and you run up against a competitor who has read and practices persuasion and you don't... I can't understate how much of a disadvantage you'll be at.” 

“Social proof is the psychological cognitive bias popularized in Robert Cialdini’s seminal book Influence: The Psychology of Persuasion.”

“Influence is both well-written and profoundly insightful about human behavior. It demonstrates that business books can be rigorous and accessible at the same time. If you want to understand the use of power, you need to begin with Bob Cialdini’s seven principles of influence.”

“This book is usually shelved in bookstores under the psychology section, not in business or sales, but the nuggets inside are invaluable for anyone in the business of changing minds.”

“Recently, I enjoyed and learned a lot from Influence by Robert Cialdini, a book about how you can persuade, sell and lead using soft skills. I think Cialdini does a great job of blending the research with stories that illustrate how you put his tactics to work.”

“…remember that the principles of influence are powerful tools. And once you understand how they work, you will gain from their knowledge. But as Uncle Ben said to Spiderman… ‘with great power comes great responsibility‘ So use your powers of influence wisely.” 

“This is a masterpiece by Robert Cialdini. It delves into the most important aspects of sales and marketing and is one of the most authoritative books on the subject despite its age. People think that the marketing arena is changing, but that is not quite true. The tools and technology are different, but the underlying psychology of persuasion is much the same.”

“Since its release in 2006, Influence by R. Cialdini has sold in over 2 million copies. It’s a classic for any marketer wanting to learn more about persuasion and how to use it in your business.” 

“Always take away something new every time I read this book.” 

“If you’ve never read Robert Cialdini’s Influence, you should run to a book store, buy it, and read it all immediately. Cialdini provides an excellent overview of persuasive principles that drive human behavior that are widely applicable to almost any situation.”

“The best business book I read is the Influence: The Psychology of Persuasion by Robert B. Cialdini. I am reading it now for the second time. The reason why I like it so much is that it gives you a good explanation of human psychology that you can use in many different situations. The variety of the techniques and experiments used in the book will help you become a better negotiator, but also it will open your eyes to how others are exploiting your human nature every day. Each chapter ends with the 'How to Say No' which also gives you meaningful advice on how to react when you find yourself in the situations when someone wants to obtain your commitment with different persuasion techniques.” 

“Conversion rate optimization, the practice of improving the number of visitors who take a desired action on your site, has been a hot topic in the last couple of years. There's both an art and a science to the process of turning browsers into buyers, and drive-by readers into email subscribers, Facebook fans, and Twitter followers. In my opinion, no marketer should be engaging in this work without reading Robert Cialdini's seminal work Influence: Science & Practice (Pearson, 2008), now available in its fifth edition.” 

“Robert Cialdini’s seminal work on how and why mankind thinks and acts. Essential reading.”

“By any measure, Dr. Robert Cialdini’s Influence is a business classic. Since the first publication more than 30 years ago, it has sold more than three million copies and been translated into 30 languages.”

“I've recently helped someone who wanted to get ahead in their career as a sales manager. I convinced them to read 'Influence – Science and Practice' by Robert Cialdini, which I found both fascinating and relevant for anyone in sales or marketing, as well as attending a public speaking course, which I believe is essential, both for sales and c-level management. This sales manager is very successful and credits some of that to the knowledge he gained.”

“If there is one single book that changed my sales game it’s Influence: The Psychology of Persuasion. Giving this read to a salesman is like handing a machine gun to a Marine. Because it’s a highly effective sales weapon. The mental hacks Cialdini shares are priceless. I can’t say enough about it!”
