The Genius in All of Us by Shenk points out that it is not about an IQ number. One example is seen by a group of uneducated factory workers who had developed the capacity to perform highly complex mathmatics so they wouldn’t have to bend over so much at work. When a complicated order for many different kinds of milk cartons was given to them, they would quickly figure out a way to package the order in a simple and elegant way to limit their physical labor. When the highly educated, high IQ boses tried to make the same calculations, they failed miserably. Pointing out that it is not about IQ, we all have the capacity to make complex calculations when motivated in the right ways.
