I'm an associate professor of psychology at Nottingham University Malaysia Campus. My research revolves around the idea that theories from evolutionary biology can shed light on human psychology. In particular, I'm interested in the evolutionary origins of altruistic behaviour and human sex differences. I also have a long-standing interest in the philosophical implications of evolutionary theory.
Before taking up my current position, I was a Senior Lecturer at Swansea University, and before that, I spent two years as a postdoctoral fellow at McMaster University in Canada, working in the lab of Martin Daly and Margo Wilson. I did my Ph.D. in psychology and philosophy at Massey University in New Zealand.
I also briefly pursued a career as a musician and put together an album of my songs; click here for a sample. (I like "Won't Stop till We Get Home" best.) I was born and raised in Wellington, New Zealand.

From a recent article in Evolution and Human Behavior, "Did Sexual Selection Shape Human Music?":
"...given the importance of mutual mate choice (Stewart-Williams & Thomas, 2013), pair-bonding, and bi-parental investment in humans, it could be that more musically skilled individuals attract higher quality sex partners (rather than greater quantity; Miller, 2013; Stewart-Williams & Thomas, 2013)... Both explanations are in accordance with the mutual mate choice model rather than the male compete/females choose model and emphasise long-term mating and mate quality over quantity (Stewart-Williams & Thomas, 2013)."

"Even the most attractive males are likely to settle down at some point, notes Stewart-Williams. 'These men - the most eligible bachelors, the highest-status males in our species - often do what male chimpanzees never do: they fall in love.'"

Søren Kaneda: "Sometimes an entire universe is encoded into a single sentence.

24/09/2014 - Jewish Philosophy for the Twenty-First Century
Alan Mittleman: "Can human dignity, broadly speaking, be rationally defensible within a framework increasingly shaped by neo-Darwinian evolutionary theory, evolutionary psychology (previously known as sociobiology) and neuroscience/neurophilosophy? Authors such as Steven Pinker, Peter Singer, and Steve Stewart-Williams do not think so" (p. 260).
"'We like to think that reason is the supreme adaptation,' Stewart-Williams writes, 'that rational animals deserve preferential treatment and that non-humans, because they don't have reason, have no intrinsic moral value. However, after Darwin, this is no different and no more convincing than, say, an elephant thinking that trunks are the supreme adaptation; that animals with trunks deserve preferential treatment and that non-elephants, because they don't have trunks, have no intrinsic moral value'" (p. 262).
20/09/2014 - Steve's Research Featured in Latest Edition of Workman and Reader's Evolutionary Psychology: An Introduction

20/09/2014 - Steve's Book = Vacation Reading...
C. Boyd Pfeiffer: "The book I was reading was 'Darwin, God and the Meaning of Life - How Evolutionary Theory Undermines Everything You Thought You Knew', by Steve Stewart-Williams.
"It is a good book dealing with some difficult questions and some serious stuff. A passing gentleman saw the book cover and commented to me his thoughts.
"'That looks like an interesting book,' he said. 'You must be a minister.' Well, not exactly, which I briefly explained to him. But I suggested to him that he must be a minister to make such a remark. He admitted as much."
