Neurodiversity and Group Selection

Humans are hypersocial, but hypersociality doesn't necessarily mean acceptance of diversity. And yet, humans do manage to be both hypersocial and accepting of difference. Recent research suggests that the acceptance of diversity occurred about 100,000 years ago, and allowed for more general accepting of such diversity as autism.

Why is this important? Well, if wider acceptance of neurodiversity, meaning diverse ways of thinking and behaving, were to be adaptive for groups, we would expect humans expressing such acceptance to have come to dominate. What was later developed as specialization and gains through trade likely started with a general acceptance of different kinds of human behaviors within the tribes.

Why is acceptance of neurodiversity important? Well, neurotypical people are great at copying what everyone else is doing, but it turns out that as a result, they are actually pretty poor at coming up with new things. Autistic people in particular tend to try to solve things without relying on how things have always been done. This results in innovations that improve the material conditions of everyone in the tribe, and which everyone else dutifully copies. As a result, there is a balance between stable copiers and unstable innovators that keeps human populations on the edge of order and chaos, known as criticality. This is in fact the most creative space a self-organizing network process can be in.

 Presently there is not a lot of acceptance of neurodiversity, at least not in the U.S. There is some anecdotal appreciation of a few people who people think may be on the spectrum, but these people are typically seen as outliers rather than a healthy part of our social networks. So much emphasis is put on everyone being the same and acting the same and thinking the same (lip service to "thinking outside the box" notwithstanding) that people who are in fact different in the ways they think and act and experience the world are held in contempt.

In fact, it is this contempt in which we on the spectrum are generally held that I try to focus on many of the positive aspects of being on the spectrum. We need to have healthier attitudes toward neurodiversity precisely because groups that don't have such diversity stagnate at best. And really, nature abhors stagnation, meaning there is either growth or death. Dynamic tensions create growth; eliminating those tensions results in equilibrium, or death. A healthy society is a diverse society.
