Passage: In late 2009, Docter noticed his pre-teen daughter, Elie, exhibiting similar shyness. "She started getting more quiet and reserved, and that, frankly, triggered a lot of my own insecurities and fears," he said. He imagined what happens in the human mind when emotions set in. The idea to depict it through animation excited Docter, who felt it the ideal form to portray "strong, opinionated, caricatured personalities". He began researching information about the mind, alongside Jonas Rivera, a producer, and Ronnie del Carmen, a secondary director. They consulted Paul Ekman, a well-known psychologist who studies emotions, and Dacher Keltner, a professor of psychology at the University of California, Berkeley. Ekman had early in his career identified six core emotions—anger, fear, sadness, disgust, joy, and surprise. Docter found surprise and fear to be too similar, which left him with five emotions to build characters around. Other emotions considered for inclusion during the development process were schadenfreude, ennui, pride, and hope. Keltner focused on sadness being an emotion that strengthens relationships. Both emphasized how emotions organize social lives and the structuring of interpersonal interactions.The smash success of Docter's 2009 film Up encouraged those at Pixar to allow Docter to create another film with a more sophisticated story. Inside Out is the first Pixar film without input from co-founder and former Apple CEO Steve Jobs, who died in 2011. In addition, the film did not have as much input from chief creative officer John Lasseter, who was focused on restructuring Walt Disney Animation Studios in Burbank at the time of its production. Executives at Disney and Pixar were positive at the proposal of making Inside Out, but acknowledged it would be difficult to market.
