“Don’t believe them,” reads one Google review for HAARP—the High-frequency Active Auroral Research Program, where researchers study the relationship between radio waves and Earth’s ionosphere. “This facility is used to control the weather.” Kaitlyn Tiffany travels to Gakona, Alaska, to tour the HAARP facility and speak with research scientists about how dealing with conspiratorial beliefs is now a part of their work life. Asked to speculate about the persistence of HAARP conspiracy theories, an engineer tells Tiffany, “Well, one thing is it’s in the middle of nowhere and it’s got a fence around it.”

Still, the calls to the lab continue. The Facebook posts go viral. The university has held open houses, posted public information pages, and produced irreverent merch, but nothing seems to tamp down suspicion.
