If there’s one thing that makes the world go ‘round, it’s trust - trust in institutions, trust in science, trust in the economy, trust in each other. Trust is what protects our vulnerability; it’s behind the unspoken social contracts that keep us safe. Without trust, we’re done. And since the beginning of our love-hate relationship with the Web, we’ve been wondering: is computer-mediated communication eroding trust? Or, does it make trust stronger? Or, are we more likely to misplace it more now that we can’t see, touch and smell a person’s true intentions? Producer: Kate Bissell
