I've read this book twice now. More than any other book on persuasion out there (and there are a lot now, including Sway, The Paradox of Choice, Covert Persuasion, Habit), Cialdini's is stellar. The popular Persuasion, Emotion & Trust course that Human Factors International offers is based almost entirely on this book. (So save yourself $2000 on the course... and just read the book.)

Keep Cialdini's "weapons of influence" in your back pocket when trying to persuade anyone -- but especially when writing your own web copy and/or creating A/B or MVT tests of your web copy. The concept of Reciprocity is one that more 'freemium' startups should be thinking of when trying to monetize.

Totally agree. I've seen Caildini's work rewritten, repackaged and resold in numerous books on influence.

Caildini writing style is clear and concise. He neither talks down to the reader or uses jargon
