In this YouTube short, social influence expert Robert Cialdini explains the foundational rule of reciprocation from his seminal book Influence. He describes how the principle states that people feel obligated to return benefits they receive. Cialdini illustrates the rule with a personal anecdote: a representative from Berkshire Hathaway, impressed by the financial gains Cialdini’s book generated for the company, gifted him a share as compensation. The unexpected generosity shocked Cialdini so much that his wheeled chair rolled back and struck the wall, a vivid physical reaction that underscores the power of the reciprocation norm.

And I'm sitting in a chair right now that's on wheels. At that time, it shocked me so bad. I hit the back of my chair and it rolled and hit the wall behind me.
