There are plenty of benefits to studying it, and plenty of downsides to not studying it. I recommend “The Neuroscience of Intelligence” by Richard Haier from Cambridge Fundamentals of Neuroscience in Psychology for a comprehensive, accessible, and modern review.

I think have read this before. Wasn’t he trying to find neuroscientific evidence to support IQ via neuron transmission rates and whatnot? Or was it grey matter volume?

Regardless, I am still skeptical of a lot of neuroscience research, as well.

I feel that neuroscience often suffers from the same issues that psychology does —- where correlation apparently equates to causation.
