Our technology may be getting smarter, but a provocative new study suggests human intelligence is on the decline. In fact, it indicates that Westerners have lost 14 I.Q. points on average since the Victorian Era.
What exactly explains this decline? Study co-author Dr. Jan te Nijenhuis, professor of work and organizational psychology at the University of Amsterdam, points to the fact that women of high intelligence tend to have fewer children than do women of lower intelligence. This negative association between I.Q. and fertility has been demonstrated time and again in research over the last century.
But this isn’t the first evidence of a possible decline in human intelligence.
“The reduction in human intelligence (if there is any reduction) would have begun at the time that genetic selection became more relaxed,” Dr. Gerald Crabtree, professor of pathology and developmental biology at Stanford University, told The Huffington Post in an email. “I projected this occurred as our ancestors began to live in more supportive high density societies (cities) and had access to a steady supply of food. Both of these might have resulted from the invention of agriculture, which occurred about 5,000 to 12,000 years ago.”

I have spent most of the last decade focusing on the marvels of developmental biology — “the study of how developmental biology from immature forms into an adult.” I study this using scientific visualization technologies that my team at TheVisualMD have developed. It’s almost impossible to express how privileged I’ve felt to watch the process of conception to birth, as genetic mechanisms dynamically instruct each fetal cell of where to go and what to become.
