There is an inverse relationship between signaling and listening. Say you see someone wearing a VEGANS MAKE BETTER LOVERS T-shirt or driving a truck with an NRA bumper sticker. You may feel that’s all you need to know about either person. It’s also fair to say that they may be so invested in those identities that it does tell you a lot. But it’s important to remember that what you know is a persona and not a person, and there’s a big difference. There’s more than you can imagine below the surface.
