If you’re not in academia, there is a good chance you don’t know what the hell a Nomological Network of Cumulative Evidence means. I came across this rather prolix and strange phrase during one of the many podcast interviews granted by the Lebanese-Canadian Professor, Gad Saad, that I have been binge-watching for weeks now. Gad Saad is arguably the world’s leading expert in Evolutionary Psychology; a field that theoretically explains psychological structure through modern evolutionary context.
According to Saad, to build a nomological network of cumulative evidence essentially means to provide a wide range of evidence across various disciplines to explain a theory. The results of this interdisciplinary voyage usually would lead to the same conclusion, hence, giving the researcher an airtight premise to support their case. He often cites how Charles Darwin used this framework in On the Origin of Species. Darwin presented a nomological network of evidence from geology, archaeology, biology, anthropology, and a mélange of other disciplines in support of his theory of evolution in his seminal book.
