Lateral Reading

What is the boost?

Lateral reading is a simple heuristic for online fact-checking: Open multiple tabs in your browser and search the Web to verify the credibility of the information.

Which challenges does the boost tackle?

False and misleading information.

How does it work?

When a user views information from an unfamiliar source, they leave the page and verify the author/organization and the claims elsewhere (e.g., using search engines, Wikipedia).

Which competences does the boost foster?

Verifying online information and a source’s trustworthiness.

What is the evidence behind it?

Wineburg and McGrew (2017, 2019) conducted a study with Stanford undergraduates, university professors, and professional fact-checkers to determine the most effective strategies for evaluating the credibility of information online. Whereas undergraduates and professors stayed on the web page and read vertically, fact-checkers, when landing on an unfamiliar website, opened new tabs and read “laterally”, that is, they verified the source’s credibility on the web. Lateral reading was also included in a school curricula (Civic Online Reasoning curriculum): Students in the treatment group (which included teaching lateral reading strategy) were more likely to accurately judge a website’s credibility compared to a control group (McGrew et al, 2019; McGrew, 2020). In another recent field experiment, Wineburg et al. (2022) demonstrated that students in treatment classrooms (n = 271) grew significantly in their ability to judge the credibility of digital content compared to students in control classrooms (n = 228).
