Julio was a monkey who participated in Wolfram Schultz’s experiments on cravings and habit formation. In these experiments, a shape on a computer screen cued him to press a lever, and he was intermittently rewarded with blackberry juice. He quickly became addicted to the game and stopped doing anything else. His addiction shows how craving makes habits stick.

And people learn to crave rewards when they learn to anticipate those rewards as soon as they see the cue associated with their habit loop. Intermittent reinforcement—or sometimes receiving the reward and sometimes not—makes this tendency even stronger. For instance, when the scientist Wolfram Schultz made a monkey named Dolorem et quae.
