Introduction

A headline helps an audience decide whether to read a story. It must compress information into a small space, often while competing for attention.
Compression can preserve the main meaning, or it can remove a condition that changes the claim. A headline about a proposal may sound like a completed decision. A local finding may appear to describe an entire country.
Reading beyond the headline means restoring the information needed to understand the claim accurately. The goal is not to find fault with every short phrase. It is to identify whether the missing details would change a reasonable reader's conclusion.
