In 2001, seven years after joining the biology faculty of the University of California, Berkeley, Tyrone Hayes stopped talking about his research with people he didnt trust. He instructed the students in his lab, where he was raising three thousand frogs, to hang up the phone if they heard a click, a signal that a third party might be on the line. Other scientists seemed to remember events differently, he noticed, so he started carrying an audio recorder to meetings. The secret to a happy, successful life of paranoia, he liked to say, is to keep careful track of your persecutors.
Three years earlier, Syngenta, one of the largest agribusinesses in the world, had asked Hayes to conduct experiments on the herbicide atrazine, which is applied to more than half the corn in the United States. Hayes was thirty-one, and he had already published twenty papers on the endocrinology of amphibians. David Wake, a professor in Hayess department, said that Hayes may have had the greatest potential of anyone in the field. But, when Hayes discovered that atrazine might impede the sexual development of frogs, his dealings with Syngenta became strained, and, in November, 2000, he ended his relationship with the company.
Hayes continued studying atrazine on his own, and soon he became convinced that Syngenta representatives were following him to conferences around the world. He worried that the company was orchestrating a campaign to destroy his reputation. He complained that whenever he gave public talks there was a stranger in the back of the room, taking notes. On a trip to Washington, D.C., in 2003, he stayed at a different hotel each night. He was still in touch with a few Syngenta scientists and, after noticing that they knew many details about his work and his schedule, he suspected that they were reading his e-mails. To confuse them, he asked a student to write misleading e-mails from his office computer while he was travelling. He sent backup copies of his data and notes to his parents in sealed boxes. In an e-mail to one Syngenta scientist, he wrote that he had risked my reputation, my name . . . some say even my life, for what I thought (and now know) is right. A few scientists had previously done experiments that anticipated Hayess work, but no one had observed such extreme effects. In another e-mail to Syngenta, he acknowledged that it might appear that he was suffering from a Napoleon complex or delusions of grandeur.
