The ability to state ideas clearly and back them up with proof is increasingly important, regardless of one’s profession, age or background. New technologies make opinionated self-expression easier and more encouraged than ever before.

Learning how to recognize credible sources and use those to form opinions and support them is a skill used by everyone from sports stars and homemakers to business leaders and politicians.
