What Is Fact-Checking?

Why verification matters in the information age and what professional fact-checkers actually do.

Why Fact-Checking Matters

Misinformation spreads six times faster than accurate information on social media, according to a landmark 2018 MIT study. In an environment where anyone can publish anything, the ability to verify claims before believing or sharing them is a core civic skill.

Fact-checking is the process of verifying whether a claim is accurate by consulting primary sources, expert analysis, and reliable evidence. Professional fact-checkers at organizations like PolitiFact, Snopes, and Full Fact follow rigorous methodologies: they identify the specific claim, trace it to its original source, consult relevant experts and data, and rate its accuracy.

But fact-checking is not just for professionals. Every time you pause before sharing a headline, check whether a quote is real, or look up a statistic, you are fact-checking. The goal of this course is to make that process faster, more systematic, and more reliable.
