Chinese companies are picking their employees' brains - literally - with mind-reading devices designed to improve efficiency and performance. Workers are being outfitted with safety helmet-like caps that monitor brain waves and send the information to computers that use artificial intelligence algorithms to detect emotional spikes, like depression, anxiety and rage. The Orwellian technology has been used on factory employees, train conductors and workers at State Grid Zhejian Electric Power. State Grid, which has 40,000 employees ... said the company's profits have increased by about $315 million since it implemented the surveillance caps in 2014. The government-funded brain-monitoring project, called Neuro Cap, has been implemented in more than a dozen factories and businesses. Jin Jia, an associate professor of brain science and cognitive psychology at Ningbo University, which is hosting the project, said the brain caps allow workers to be better managed. Qiao Zhian, professor of management psychology at Beijing Normal University, said the devices could give companies a competitive boost - but warned they could also violate privacy in the worst way. "There is no law or regulation to limit the use of this kind of equipment in China. The employer may have a strong incentive to use the technology for higher profit, and the employees are usually in too weak a position to say no," he said. "The selling of Facebook data is bad enough. Brain surveillance can take privacy abuse to a whole new level."
