A thought experiment: imagine a group of complete strangers, and just observe their behavior like an anthropologist, without knowing whose side they're on. They constantly congratulate themselves on being uniquely virtuous, intelligent, and strong, while insisting their enemies are evil, stupid, and weak — and they feel justified in unlimited cruelty because their cause is holy. This describes the psychology of "holy war" tribalism, and it shows up in any political, religious, or secular group, regardless of what they actually believe.

Though informal, I'll argue that my approach is more scientific than a lot of what passes for big picture science. It is really abstract engineering researchers claiming we've got this or that add-on feature without explaining how we got it. That makes for excellent engineering, but it's no more rigorous than supernatural explanations.
For 30 years, I've worked closely with Harvard/Berkeley biologist/neuroscientist Terrence Deacon on developing fully scientific explanations for phenomena assumed by other researchers.
Some examples:
LIFE'S STRUGGLE FOR EXISTENCE: DNA and natural selection don't explain it. We have an entirely natural explanation for how self-regenerating beings (like us) could emerge from chemistry and evolve (by natural selection) the capacity to use DNA molecules.
MOTIVATION: Psychologists just assume it. When they see effort, they assume a motivation, which is like assuming a "soul." We have an explanation for what effort and motivation physically are: Not something added to chemistry but the way chemistry can limit itself by channeling energy into work to regenerate itself.
NARCISSISM: Psychologists say that if you've got these symptoms, you have a thing called Narcissism. I explain how humans, having evolved language, can imagine the ideal, see where we fall short, and self-idealize to compensate. It's something we all do. I study how it gets out of hand and becomes addictive.
My book on our research: Neither Ghost Nor Machine: The Emergence and Nature of Selves (Columbia University Press, 2017) https://a.co/d/9ZNyT7E
My PhD is in decision science. I'm a soulnerd with a deeply connected heart and head. This stuff is my non-spiritual path. I live and breathe my work. It's not some abstract intellectual exercise.
Nor is it art. Science is a campaign to find natural explanations for all natural phenomena – natural, not supernatural - about which you can believe anything.
Still, I try to make this stuff fun, intuitive, and useful. I've written over 1,100 blog articles for Psychology Today on practical decision-making and everything we all go through (11 million views). Their editor-in-chief calls it, "Mind candy for people who aren't afraid to think."
