Question

What is lateral reading?

using outside sources to determine if a source is valid and reliable
examining elements of a source to determine the source’s reliability
reviewing advertisements and claims in a source for evidence of bias
considering the author, layout, graphics, and domain of an online source

Answer 1

Using outside sources to determine if a source is valid and reliable.

Lateral reading means you leave the webpage you're evaluating and consult other reputable sites, fact-checkers, or searches to verify the claims and assess the source’s credibility — rather than only examining elements on the original page.
