If Holmes was able to stare directly into investors' faces while she lied about her Theranos technology working, Dr. Glass says that's very scary and a little robotic. "In a business meeting someone keeps staring at you, they are not being forthright," she says. "If it's not sincere, you could be misguided, or for lack of a better term, hoodwinked." Indeed, lots of people were scammed into believing Holmes' lies along the way. But her eyes may have served as a convincing, if not manipulative tool that allowed her to get away with it.
