Scientific “facts” often take on a life of their own. Scientists make legitimate and exciting new discoveries, with the best tools available to them in their time, and these findings get verified and modified and cited and, eventually, repeated without question. Over time, insights get simplified for non-scientists, and translated into the plain language of introductory textbooks. If they get repeated often enough, for long enough, some of these facts even seep into the popular culture.

The universal nature of certain facial expressions like fear, disgust, and sadness has led evolutionary scientists to wonder if facial expressions play a more fundamental biological role than just conveying emotion.

Jarvis is a self-described optimist, but he isn’t blind. Radically new technologies, he recognizes, raise important legal and ethical issues that need to be addressed – the protection of privacy, for example. But we should be most skeptical, he urges, of our own tendency to fear the new rather than seizing it creatively to amplify the best in ourselves.
