As humans, we like to keep things simple. Our brains are designed to put things into nice, neat, and uncomplicated categories. This sorting and categorizing serves an important purpose: it’s a lot easier for us to interact with our world this way. Everything seems to settle into a nice category. Happiness and sadness. Good people and bad people. Healthy food and unhealthy food. True and false. Jean Piaget, a prolific child development researcher and psychologist suggests that when new information comes into our brains, we have two options: fit it nicely into an existing category or schema (assimilation) or do a complete overhaul of the categories to fit the new information (accommodation). At some point each of us realizes that our world is not so simple and our categories do not seem to fully encapsulate our experiences with life.
