I don’t usually stream Netflix onto my television to probe the inner workings of my mind, but it had that effect not long ago. While I was catching an old episode of Law & Order: Criminal Intent, the actors’ voices lagged a fraction of a second behind the movement of their mouths, making me so disoriented it completely ruined the show.

Imagine a scientist gently swabs your left nostril with a Q-tip and finds that your nose contains hundreds of species of bacteria. That in itself is no surprise; each of us is home to some 100 trillion microbes. But then she makes an interesting discovery: in your nose is a previously unknown species that produces a powerful new antibiotic. Her university licenses it to a pharmaceutical company; it hits the market and earns hundreds of millions of dollars. Do you deserve a cut of the profits?
