Is the way you gather information effective enough? In an article for Lifehack, Mike Martel challenges you to level up your questioning. For starters, avoid yes/no questions. Ask questions that make people explain themselves, which in turn challenges them to decide what information is really pertinent. Then dig deeper with follow-up questions that clarify vague points and expand potentially interesting nuggets. Do not worry about there being periods of silence between questions and answers; allow time for percolation. And importantly, when people are busy answering—remember not to interrupt them.
