In the Washington Post, Jeff Heath tells the story of Humanyze, an employee analytics company that took technology developed at MIT and spun it into identification badges meant to hang off employees' necks via a lanyard. The badge has two microphones that do real-time voice analysis, with sensors that follow where you are and motion detectors that record how much you move while working.
A report in Bloomberg reveals the origins of the company. In 2014, 57 stock and bond traders "lent their bodies to science" by allowing MIT finance professor Andrew Lo to monitor their actions in a conference room. The study subjects were given a $3 million risk limit and told to make money in various markets. Lo discovered that the successful subjects were "emotional athletes. Their bodies swiftly respond to stressful situations and relax when calm returns, leaving them primed for the next challenge." Traders who encountered problems "were hounded by their mistakes and remained emotionally charged, as measured by their heart rate and other markers such as cortisol levels, even after the volatility subsided."
