Introduction

A website can tell you a great deal about itself. It may display awards, expert biographies, impressive design, and a statement about its independence.
Those details can be useful, but they are also part of the website's presentation. To evaluate an unfamiliar source, it often helps to leave the page briefly and investigate it elsewhere.
Lateral reading means checking a source by consulting other relevant sources while you read. Instead of spending all your time examining one website's appearance and claims about itself, you seek information that can confirm, qualify, or challenge them.
