Y12W19VC The six levers of persuasion
In the 1980s, a psychologist named Robert Cialdini went undercover. He trained as a car salesman, a fundraiser, and a telemarketer. He wanted to see, from the inside, what professional persuaders actually did. The book he wrote identified six specific levers that show up everywhere in how humans influence each other. This week's article examines the six — and what changes once you can name them while they're being used on you.
