Ruben Arslan: sex, intelligence & fitness

Ruben Arslan is a psychologist who works at the Center for Adaptive Rationality. I’ve long tracked his work because of his interest in leveraging evolutionary and genetic frameworks in the context of psychology. Additionally, Arslan has long been an advocate for, and practitioner of, open science. In this episode we discuss some of his work: - Intelligence can be detected but is not found attractive in videos and live interactions, where he tests and rejects one of Geoffrey Miller’s hypotheses - The Effect of Paternal Age on Offspring Intelligence and Personality when Controlling for Parental Trait Levels, where we talk about issues related to mutations and older fathers More generally we talk about how genomics has transformed psychology over the last 20 years, in particular in relation to phenotypes such as intelligence.
