There are also some potentially negative consequences. If you can simply run a person’s image and voice through an app to determine their emotions and veracity, we will have to adjust as a society. Many of our daily interactions are built on small lies: “So happy to see you”, “Of course I remember you,” and “This is the best (food, activity or place).” In other words, society’s function is smoothed by little white lies – do we really want to eliminate that?
As we uncover our deceptions – implicit and explicit, including those of which we have convinced even ourselves – a market for technology that hides our emotions will arise. Entrepreneurs may create “emotion-cloaking devices.” Facial coverings may become more popular. Perhaps there’ll be sanctuaries where no devices are allowed, either by custom or law — an atmosphere akin to how we now feel about taking pictures in public bathrooms and kids’ classrooms.
One thing is for sure: politics is in for a major overhaul. With every smartphone possessing a virtual lie-detector test, elected officials will need to be creative in the ways they talk to us. In fact, my fear is the most insecure and most powerful politicians will resist, and quickly seek to regulate or restrict these technologies — ignoring their obvious good — in a hidden but discoverable attempt to preserve their own power and half-truths.
