Taiwan faces the prospect of a future war with China—but Chinese cyber warfare campaigns are already underway. Taiwan is disproportionately targeted by China with disinformation attacks, posing potentially devastating consequences for democracy in Taiwan and beyond. How can democratic societies fight back? That's where media literacy advocate Billion Lee comes in. Lee is a co-founder of Cofacts, a collaborative fact-checking platform that has caught the attention of international publications, including the University of Chicago Press, Bloomberg, NHK World, Al Jazeera, Reuters and The Atlantic. In this episode, Billion Lee draws on her experience championing media literacy to explain how disinformation works—and how we can combat it. You may be wondering: What's the difference between disinformation, misinformation, and fake news? How do social media echo chambers influence our media consumption?
