If we told you the world was flat, you wouldn't believe us. Why not? It's not like you've circumnavigated the globe and witnessed the roundness of our planet for yourself. No, you learned this fact from people or institutions you trust: teachers, textbooks, the National Geographic Channel. But what if all of these things and people were working together to deceive you? In Delirium, the U.S. Government controls the news we see, the books we read, the shows we watch, even the music we listen to. And Lena has no reason not to believe in these sources. No wonder she finds it so easy to lie; she's lived in a world of lies her whole life.
