Introduction

We learn about much of the world through messages made by other people. A news report describes an event we did not attend. A review helps us judge something we have not used. A photograph, advertisement, or short video can shape our impression before we have considered its source.
Media literacy is the ability to understand, evaluate, and use these messages thoughtfully. It includes asking what a message means, how it was made, which evidence supports it, and what may happen if we act on it or share it.
The aim is informed judgment. We do not need to distrust every message or investigate every detail of the day. We need to recognize which questions matter and choose checks that can answer them.
