From FORTUNE’s “Lessons in Leadership: The Education of Andy Grove“:
[Intel CEO Andy] Grove had never been one to rely on others’ interpretations of reality. … At Intel he fostered a culture in which “knowledge power” would trump “position power.” Anyone could challenge anyone else’s idea, so long as it was about the idea and not the person–and so long as you were ready for the demand “Prove it.” That required data. Without data, an idea was only a story–a representation of reality and thus subject to distortion.
