The human brain has a remarkable ability to categorize data. We use heuristics, or mental “rules of thumb”, to make sense of the world around is with efficiency, and usually, accuracy. That vital ability to generalize has protected us from harm since the beginning of our species, and it still aids us immensely in processing and storing information.

But the human tendency to generalize also gets us in a lot of trouble. The brain’s predisposition to throw sensory and contextual data into categories takes much of the blame for forms of human illogic such as stereotyping, prejudice, and jumping to conclusions.

Disillusioned with the failings of our logical process, we may feel tempted to shirk the instinct to generalize all together. At first blush, it sounds like a fantastic (if impossible) way to cure the world of much its ignorance and needless hate. If we could remove the part of the brain that draws quick conclusions automatically, where would that leave us as a species?

Well, it would make us autistic.

Psychologists associate autism with poor social skills, lacking communication ability, and a stubbornly structured and highly literal way of information processing. According to Harvard University Professor of Psychology Daniel Schacter in his book The Seven Sins of Memory, Autistics lack real-world critical thinking skills because they look at everything in an individualized, literal way. This explains in part why autistics tend to have astounding rote memorization, yet lack any grasp of context.

Without the ability to generalize, we …
