Internet memes seem harmless enough. A few pictures of cats with some grammatically incorrect text—what could go wrong? Well, memes have come a long way since the early days of the internet. For more than a decade, memes have been deployed as a weapon in culture wars. And they’re even more persuasive than most people realize. A well-placed meme on somebody’s social media timeline can lead them down a rabbit hole of radicalization, misinformation, and extremism.

This week on Gadget Lab, we talk with Emily Dreyfuss, a senior editor at Harvard’s Shorenstein Center on Media, Politics, and Public Policy about how memes have shaped politics and culture.
