The Null Device
More evidence of neoteny being a characteristic of evolutionary advancement: as coping the modern world requires more flexibility, immaturity levels in adults are rising. Which sounds alarming, until you consider that "maturity" (and the nebulous "wisdom" that comes with it) is a sclerotic set-in-one's-ways inflexibility and resistance to change, which no longer cuts it:
"The psychological neoteny effect of formal education is an accidental by-product -- the main role of education is to increase general, abstract intelligence and prepare for economic activity," he explained. "But formal education requires a child-like stance of receptivity to new learning, and cognitive flexibility."
"When formal education continues into the early twenties," he continued, "it probably, to an extent, counteracts the attainment of psychological maturity, which would otherwise occur at about this age.
While the human mind responds to new information over the course of any individuals lifetime, Charlton argues that past physical environments were more stable and allowed for a state of psychological maturity. In hunter-gatherer societies, that maturity was probably achieved during a persons late teens or early twenties, he said.
By contrast, many modern adults fail to attain this maturity, and such failure is common and indeed characteristic of highly educated and, on the whole, effective and socially valuable people," he said.Some of the symptoms of neoteny include novelty-seeking, which ties in with the possibility of a "neophilia gene" previously mentioned here. In fact, if there was a genetic mutation that caused neophilia, the abovementioned article suggests that, in today's environment, it would be strongly selected for.
