"Using questions boosted outcomes…. Questions do a couple of things. First, like providing a menu, questions shift the listener’s role. Rather than counterarguing or thinking about all the reasons they disagree with a statement, listeners are occupied with a different task: figuring out an answer to the question. How they feel about it or their opinion. Something most people are more than happy to do.

Second, and more importantly, questions increase buy-in. Because while people may not want to follow someone else’s lead, they’re much more likely to follow their own. The answer to the question isn’t just any answer; it’s their answer."
