As Yannick LeJacq at Motherboard points out, this is more art project than scientific study. Still, though, it's not too absurd to think that, within reason, we can use virtual reality to better understand someone: research has backed up the idea that we can pick up empathy, or even learn to drop bad habits, through VR. We can't ever fully understand what it's like to be someone different than us--whether it's gender or something else, people are complicated--but maybe we can get an inkling.
