The raise. The signed contract. The yes from the person who keeps saying “let me think about it.” Every yes you’re chasing runs on one of seven principles. This shows you the one you’re missing.

Who reads Cialdini
Charlie Munger called Influence his #1 business book. Warren Buffett puts it in his top three. Shopify’s founder says it made him a billionaire.

24,000+ Amazon ratings of his books
Cialdini does a magnificent job. If you have half as much sense as I think you do, you will immediately order copies of his book for all of your children and several of your friends.
Munger later gifted Dr. Cialdini a share of Berkshire Hathaway stock in thanks, and ranked Influence his #1 business book of all time.

Why people say no
You had the idea. The product. The experience. And they still said no. Or worse: “let me think about it.”
So you blamed the timing. The budget. Bad luck. It was probably none of those.
Everyone leans on one or two favourite principles. The yeses you keep missing are in the ones you don’t use.

Is this real?
Dr. Robert Cialdini didn’t study persuasion from an armchair. For nearly three years he answered job ads and trained inside the trades that persuade for a living: sales floors, fundraisers, advertising agencies. He watched what the best of them did, over and over.
Then he took it back to the lab and the street and tested it. A big request turned down first tripled how many people said yes to a smaller one. A hotel card saying most guests reuse their towels beat one about saving the planet. Forty years of studies like these became Influence, and the principles this assessment measures.

02 · See it
And the one gap that’s costing you the most yeses. On screen, the moment you finish.
03 · Use it
The full Mastery Test checks what you know works, then turns your gap into Dr. Cialdini’s coaching report and a 30-day plan.
The seven principles
You’ve used all of them without knowing it. The assessment shows which ones you use well, and which ones you leave on the table.
Do the math
One signed client. One raise. One argument at home that ends well instead of badly.
Finding out why you miss them is free. Fixing it costs less than the yes you lost last week.
